2 Overall objectives

The goal of the project is the modeling of speech for facilitating oral-based communication. The name MULTISPEECH comes from the following aspects that are particularly considered.

  • Multisource aspects - which means dealing with speech signals originating from several sources, such as speaker plus noise, or overlapping speech signals resulting from multiple speakers; sounds captured from several microphones are also considered.
  • Multilingual aspects - which means dealing with speech in a multilingual context, as for example for computer assisted language learning, where the pronunciation of words in a foreign language (i.e., non-native speech) is strongly influenced by the mother tongue.
  • Multimodal aspects - which means considering simultaneously the various modalities of speech signals, acoustic and visual, in particular for the expressive synthesis of audio-visual speech.

Our objectives are structured in three research axes, which have evolved compared to the original project proposal in 2014. Indeed, due to the ubiquitous use of deep learning, the distinction between `explicit modeling' and `statistical modeling' is not relevant anymore and the fundamental issues raised by deep learning have grown into a new research axis `beyond black-box supervised learning'. The three research axes are now the following.

  • Beyond black-box supervised learning This research axis focuses on fundamental, domain-agnostic challenges relating to deep learning, such as the integration of domain knowledge, data efficiency, or privacy preservation. The results of this axis naturally apply in the various domains studied in the two other research axes.
  • Speech production and perception This research axis covers the topics of the research axis on `Explicit modeling of speech production and perception' of the project proposal, but now includes a wide use of deep learning approaches. It also includes topics around prosody that were previously in the research axis on `Uncertainty estimation and exploitation in speech processing' in the project proposal.
  • Speech in its environment The themes covered by this research axis mainly correspond to those of the axis on `Statistical modeling of speech' in the project proposal, plus the acoustic modeling topic that was previously in the research axis on `Uncertainty estimation and exploitation in speech processing' in the project proposal.

A large part of the research is conducted on French and English speech data; German and Arabic languages are also considered either in speech recognition experiments or in language learning. Adaptation to other languages of the machine learning based approaches is possible, depending on the availability of speech corpora.

3 Research program

3.1 Beyond black-box supervised learning

This research axis focuses on fundamental, domain-agnostic challenges relating to deep learning, such as the integration of domain knowledge, data efficiency, or privacy preservation. The results of this axis naturally apply in the domains studied in the two other research axes.

3.1.1 Integrating domain knowledge

State-of-the-art methods in speech and audio are based on neural networks trained for the targeted task. This paradigm faces major limitations: lack of interpretability and of guarantees, large data requirements, and inability to generalize to unseen classes or tasks. We research deep generative models as a way to learn task-agnostic probabilistic models of audio signals and design inference methods to combine and reuse them for a variety of tasks. We pursue our investigation of hybrid methods that combine the representational power of deep learning with statistical signal processing expertise by leveraging recent optimization techniques for non-convex, non-linear inverse problems. We also explore the integration of deep learning and symbolic reasoning to increase the generalization ability of deep models and to empower researchers/engineers to improve them.

3.1.2 Learning from little/no labeled data

While fully labeled data are costly, unlabeled data are cheap but provide intrinsically less information. Weakly supervised learning based on not-so-expensive incomplete and/or noisy labels is a promising middle ground. This entails modeling label noise and leveraging it for unbiased training. Models may depend on the labeler, the spoken context (voice command), or the temporal structure (ambient sound analysis). We also study transfer learning to adapt an expressive (audiovisual) speech synthesizer trained on a given speaker to another speaker for which only neutral voice data has been collected.

3.1.3 Preserving privacy

Some voice technology companies process users' voices in the cloud and store them for training purposes, which raises privacy concerns. We aim to hide speaker identity and (some) speaker states and traits from the speech signal, and evaluate the resulting automatic speech/speaker recognition accuracy and subjective quality/intelligibility/identifiability, possibly after removing private words from the training data. We also explore semi-decentralized learning methods for model personalization, and seek to obtain statistical guarantees.

3.2 Speech production and perception

This research axis covers topics related to the production of speech through articulatory modeling and multimodal expressive speech synthesis, and topics related to the perception of speech through the categorization of sounds and prosody in native and in non-native speech.

3.2.1 Articulatory modeling

Articulatory speech synthesis relied on 2D and 3D modeling of the dynamics of the vocal tract from real-time MRI data. The prediction of glottis opening is also considered so as to produce better quality acoustic events for consonants. The coarticulation model developed to handle the animation of the visible articulators will be extended to control the face and the tongue. This helps characterize links between the vocal tract and the face, and illustrate inner mouth articulation to learners. The suspension of articulatory movements in stuttering speech is also studied.

3.2.2 Multimodal expressive speech

The dynamic realism of the animation of the talking head, which has a direct impact on audiovisual intelligibility, continues to be our goal. Both the animation of the lower part of the face relating to speech and of the upper part relating to the facial expression are considered, and development continues towards a multilingual talking head. We investigate further the modeling of expressivity both for audio-only and for audiovisual speech synthesis. We also evaluate the benefit of the talking head in various use cases, including children with language and learning disabilities or deaf people.

3.2.3 Categorization of sounds and prosody

Reading and speaking are basic skills that need to be mastered. Further analysis of schooling experience will allow a better understanding of reading acquisition, especially for children with some language impairment. With respect to L1/L2 language interference1, a special focus is set on the impact of L2 prosody on segmental realizations. Prosody is also considered for its implication on the structuration of speech communication, including on discourse particles. Moreover, we experiment the usage of speech technologies for computer assisted language learning in middle and high schools, and, hopefully, also for helping children learning to read.

3.3 Speech in its environment

The themes covered by this research axis correspond to the acoustic environment analysis, to speech enhancement and noise robustness, and to linguistic and semantic processing.

3.3.1 Acoustic environment analysis

Audio scene analysis is key to characterize the environment in which spoken communication may take place. We investigate audio event detection methods that exploit both strongly/weakly labeled and unlabeled data, operate in real-world conditions, can discover novel events, and provide a semantic interpretation. We keep working on source localization in the presence of nearby acoustic reflectors. We also pursue our effort at the interface of room acoustics to blindly estimate room properties and develop acoustics-aware signal processing methods. Beyond spoken communication, this has many applications to surveillance, robot audition, building acoustics, and augmented reality.

3.3.2 Speech enhancement and noise robustness

We pursue speech enhancement methods targeting several distortions (echo, reverberation, noise, overlapping speech) for both speech and speaker recognition applications, and extend them to ad-hoc arrays made of the microphones available in our daily life using multi-view learning. We also continue to explore statistical signal models beyond the usual zero-mean complex Gaussian model in the time-frequency domain, e.g., deep generative models of the signal phase. Robust acoustic modeling will be achieved by learning domain-invariant representations or performing unsupervised domain adaptation on the one hand, and by extending our uncertainty-aware approach to more advanced (e.g., nongaussian) uncertainty models and accounting for the additional uncertainty due to short utterances on the other hand, with application to speaker and language recognition “in the wild”.

3.3.3 Linguistic and semantic processing

We seek to address robust speech recognition by exploiting word/sentence embeddings carrying semantic information and combining them with acoustical uncertainty to rescore the recognizer outputs. We also combine semantic content analysis with text obfuscation models (similar to the label noise models to be investigated for weakly supervised training of speech recognition) for the task of detecting and classifying (hateful, aggressive, insulting, ironic, neutral, etc.) hate speech in social media.

4 Application domains

Approaches and models developed in the MULTISPEECH project are intended to be used for facilitating oral communication in various situations through enhancements of communication channels, either directly via automatic speech recognition or speech production technologies, or indirectly, thanks to computer assisted language learning. Applications also include the usage of speech technologies for helping people in handicapped situations or for improving their autonomy. Related application domains include multimodal computer interaction, private-by-design robust speech recognition, health and autonomy (more precisely aided communication and monitoring), and computer assisted learning.

4.1 Multimodal Computer Interaction

Speech synthesis has tremendous applications in facilitating communication in a human-machine interaction context to make machines more accessible. For example, it started to be widely common to use acoustic speech synthesis in smartphones to make possible the uttering of all the information. This is valuable in particular in the case of handicap, as for blind people. Audiovisual speech synthesis, when used in an application such as a talking head, i.e., virtual 3D animated face synchronized with acoustic speech, is beneficial in particular for hard-of-hearing individuals. This requires an audiovisual synthesis that is intelligible, both acoustically and visually. A talking head could be an interface between two persons communicating remotely when their video information is not available, and can also be used in language learning applications as vocabulary tutoring or pronunciation training tool. Expressive acoustic synthesis is of interest for the reading of a story, such as an audiobook, as well as for better human-machine interaction.

4.2 Private-by-design robust speech recognition

Many speech-based applications process speech signals on centralized servers. However speech signals exhibit a lot of private information. Processing them directly on the user's terminal helps keeping such information private. It is nevertheless necessary to share large amounts of data collected in actual application conditions to improve the modeling and thus the quality of the resulting services. This can be achieved by anonymizing speech signals before sharing them. With respect to robustness to noise and environment, the speech recognition technology is combined with speech enhancement approaches that aims at extracting the target clean speech signal from a noisy mixture (environment noises, background speakers, reverberation, ...).

4.3 Aided Communication and Monitoring

Source separation techniques should help locate and monitor people through the detection of sound events inside apartments, and speech enhancement is mandatory for hands-free vocal interaction. A foreseen application is to improve the autonomy of elderly or disabled people, e.g., in smart home scenarios. In the longer term, adapting speech recognition technologies to the voice of elderly people should also be useful for such applications, but this requires the recording of suitable data. Sound monitoring in other application fields (security, environmental monitoring) can also be envisaged.

4.4 Computer Assisted Learning

Although speaking seems quite natural, learning foreign languages, or one's mother tongue for people with language deficiencies, represents critical cognitive stages. Hence, many scientific activities have been devoted to these issues either from a production or a perception point of view. The general guiding principle with respect to computer assisted mother or foreign language learning is to combine modalities or to augment speech to make learning easier. Based upon an analysis of the learner’s production, automatic diagnoses can be considered. However, making a reliable diagnosis on each individual utterance is still a challenge, which is dependent on the accuracy of the segmentation of the speech utterance into phones, and of the computed prosodic parameters.

5 Social and environmental responsibility

A. Deleforge co-founded and co-chairs the Commission pour l'Action et la Responsabilité Ecologique (CARE), formerly called the Commission Locale de Développement Durable, a joint entity between Loria and Inria Nancy. Its goals are to raise awareness, guide policies and take action at the lab level and to coordinate with other national and local initiatives and entities on the subject of the environmental impact of science, particularly in information technologies.

6 Highlights of the year

Asteroid, our Python toolbox for audio source separation and speech enhancement was released in May 2020 51. It has received more than 700 Github stars since then. Using this toolbox, Manuel Pariente and Michel Olvera won the first place in the PyTorch Summer Hackathon 20202 with DeMask, a method to enhance speech spoken by talkers wearing face masks.

Emmanuel Vincent co-organized the first VoicePrivacy Challenge 61.

We participated in the Oriental Language Recognition Challenge (OLR 2020). The system we have proposed has been ranked in first position (among the systems proposed by about 20 teams) for the two tasks in which we participated: Task 1 on cross-channel language identification, and Task 3 on noisy data language identification.

7 New software and platforms

7.1 New software

7.1.1 COMPRISE Voice Transformer

  • Name: COMPRISE Voice Transformer
  • Keywords: Speech, Privacy
  • Functional Description: COMPRISE Voice Transformer is an open source tool that increases the privacy of users of voice interfaces by converting their voice into another person’s voice without modifying the spoken message. It ensures that any information extracted from the transformed voice can hardly be traced back to the original speaker, as validated through state-of-the-art biometric protocols, and it preserves the phonetic information required for human labelling and training of speech-to-text models.
  • Release Contributions: This version gives access to the 2 generations of tools that have been used to transform the voice, as part of the COMPRISE project (https://www.compriseh2020.eu/). The first one is a python library that implements 2 basic voice conversion methods, both using VLTN. The second one implements an anonymization method using x-vectors and neural waveform models.

7.1.2 COMPRISE Weakly Supervised STT

  • Name: COMPRISE Weakly Supervised Speech-to-Text
  • Keywords: Speech recognition, Language model, Acoustic Model
  • Functional Description: COMPRISE Weakly Supervised Speech-to-Text provides two main components for training Speech-to-Text (STT) models. These two components represent the two main approaches proposed in the COMPRISE project, namely (a) semi-supervised training driven by error predictions and (b) weakly supervised training based on utterance level weak labels. These two approaches can be used independently or together. The implementation builds on the Kaldi toolkit. It mainly focuses on obtaining reliable transcriptions of un-transcribed speech data which can be used for training both STT acoustic model (AM) and language model (LM). AM can be any type, although we choose the state-of-the-art TDNN Chain AM in our examples. Statistical n-gram LMs are chosen to support limited data scenarios.

7.1.3 Kaldi-web

  • Name: Kaldi-web
  • Keyword: Speech recognition
  • Functional Description: Today, developers willing to implement a voice interface must either rely on proprietary software or become experts in speech recognition. Conversely, researchers in speech recognition wishing to demonstrate their results need to be familiar with other technologies (e.g., graphical user interfaces). Kaldi-web is an open-source, cross-platform tool which bridges this gap by providing a user interface built around the online decoder of the Kaldi toolkit. Additionally, because we compile Kaldi to Web Assembly, speech recognition is performed directly in web browsers. This addresses privacy issues as no data is transmitted to the network for speech recognition.

7.1.4 Asteroid

  • Name: Asteroid: The PyTorch-based audio source separation toolkit for researchers.
  • Keywords: Source Separation, Deep learning
  • Functional Description: Asteroid is an open-source toolkit made to design, train, evaluate, use and share neural network based audio source separation and speech enhancement models. Inspired by the most successful neural source separation systems, Asteroid provides all neural building blocks required to build such a system. To improve reproducibility, Kaldi-style recipes on common audio source separation datasets are also provided. Experimental results obtained with Asteroid’s recipes show that our implementations are at least on par with most results reported in reference papers.

7.1.5 DNNuep

  • Name: DNN uncertainty estimation and propagation
  • Keyword: Speech recognition
  • Functional Description: From a noisy signal and its noiseless version, the system estimates the uncertainty and propagates it in an automatic speech recognition system.

  • Participants: Irina Illina, Dominique Fohr, Ismaël Bada

7.1.6 DNNsem

  • Keywords: Speech recognition, Semantic
  • Functional Description: DNNsem is a software for rescoring the N-best list of hypotheses of an automatic speech recognition (ASR) system. It is useful in the situation when the training and testing conditions differ due to noise or other acoustic distortions. To improve performance in such conditions, DNNsem accounts for long-term semantic relations. It takes as inputs the list of N-best ASR hypotheses and the corresponding acoustic scores, and it outputs a reranked list by favoring words that better correspond to the semantic context of the sentence. To do so, it uses two continuous word representations: word2vec or FastText.
  • News of the Year: Development of version 1.0 of the software. Implementation of two methods, based on static word embeddings (word2vec) or dynamic word embeddings (BERT). Performance evaluation on a noisy speech corpus.
  • Contact: Irina Illina
  • Participants: Irina Illina, Dominique Fohr

7.1.7 Web-based Pronunciation Learning Application

  • Keywords: Pronunciation training, Talking head, Second language learning
  • Functional Description: This web-based application is dedicated to foreign language pronunciation learning (current version was developed for the German language). It is intended for high school and middle school students. There are two types of exercises that are integrated in this application. (1) Flashcards: Cards are presented, then a virtual teacher (a 3D talking head) pronounces the words and sentences corresponding to these cards. Students can practice and make an evaluation of their word comprehension. (2) Speech recognition. The application displays a list of words/phrases that the student pronounces and the system gives feedback on the quality of the pronunciation. This application is composed of two modules: one for students (described above) and one for teachers, allowing them to create lessons, and to follow the results and progress of student evaluations.

7.1.8 Grapheme-phoneme aligner

  • Keywords: Grapheme-to-phoneme converter, Grapheme-phoneme alignment
  • Functional Description: This software processes French words or sentences to determine their pronunciation, and to provide the association between letters and sounds. It calls SOJA to preprocess the text, and LORIA-PHON to determine the pronunciation of the words. It then aligns, through a set of rules, the letters of the text with the phonemes of the predicted pronunciation.

8 New results

8.1 Beyond black-box supervised learning

8.1.1 Integrating domain knowledge

Integration of signal processing knowledge

State-of-the-art methods for single-channel speech enhancement or separation are based on end-to-end neural networks including learned real-valued filterbanks. We tackled two limitations of this approach. First, to ensure that the representation properly encodes phase properties as the short time Fourier transform and other conventional time-frequency transforms, we designed complex-valued analytic learned filterbanks and defined corresponding representations and masking strategies which outperformed the popular ConvTasNet algorithm 52. This advance formed the basis for the Asteroid toolbox 51 which provides various choices of filterbanks, network architectures and loss functions, as well as training and evaluation tools and recipes for several datasets. Asteroid performs on par with or better than the results reported in reference papers, and it has received more than 700 Github stars since its release in May 2020. Second, in order to allow generalization to mixtures of sources not seen together in training, we pursued the modeling of speech signals by variational autoencoders (VAEs), which are a variant of the probabilistic generative models classically used in source separation before the deep learning era. We extended the model developed last year for magnitude spectra to complex-valued spectra.

8.1.2 Learning from little/no labeled data

Unsupervised or semi-supervised acoustic modeling

ASR systems are typically trained in a supervised fashion using manually labeled data. To reduce the cost of labeling, we investigated semi-supervised training of acoustic models in practical scenarios with a limited amount of labeled in-domain data 55. We proposed an error detection driven semi-supervised training approach, in which an error detector controls the hypothesized transcriptions or lattices used as training targets on additional unlabeled data, and achieved word error recovery rates of 28 to 89%. We also studied the recognition of accented speech, where the accented training data is unlabeled 63. To do so, we computed xvector-like accent embeddings and used them as auxiliary inputs to an acoustic model trained on native data only. We achieved a 15% relative word error rate reduction on accented speech w.r.t. acoustic models trained with regular spectral features only, and an additional 15% relative reduction by semi-supervised training using 1 hour of untranscribed speech per accent only.

Transfer learning applied to speech synthesis

We worked on the disentanglement of speaker, emotion and content in the acoustic domain for transferring expressivity information from one speaker to another one, particularly when only neutral speech data is available for the latter. We have proposed an approach relying on multiclass N-pair based deep metric learning in a recurrent conditional variational autoencoder (RCVAE) for implementing a multispeaker expressive text-to-speech system. The proposed approach conditions the text-to-speech system on speaker embeddings, and leads to a clustering with respect to emotion in a latent space. Deep metric learning helps to reduce the intra-class variance and increase the inter-class variance. We transfer the expressivity by using the latent variables for each emotion to generate expressive speech in the voice of a different speaker for which no expressive speech is available 42. The approach has then been applied using an inverse autoregressive flow as a way to perform the variational inference 43, and more recently using an end-to-end text-to-speech synthesis system based on Tacotron 2 92.

8.1.3 Preserving privacy

Speech signals involve a lot of private information. With a few minutes of data, the speaker identity can be modeled for malicious purposes like voice cloning, spoofing, etc. To reduce this risk, we investigated speaker anonymization strategies based on voice conversion. In contrast to prior evaluations, we argue that different types of attackers can be defined depending on the extent of their knowledge. We compared three simple conversion methods in three attack scenarios, and showed that these methods fail to protect against an attacker that has extensive knowledge of the type of conversion and how it has been applied, but may provide some protection against less knowledgeable attackers 60. We then developed a more advanced conversion method and explored several design choices for the distance metric between the source and target speakers, the region of x-vector space where the target speaker is picked, and gender selection to find the optimal combination of design choices in terms of privacy and utility 59. The resulting software served as a baseline for the 1st Voice Privacy Challenge 61. We have investiagted the modification of the fundamental frequency to improve consistency with the selected target x-speaker 89, 23. We also conducted a comparative study of speech anonymization metrics from a theoretical and experimental point of view 48.

8.2.1 Articulatory modeling

Exploitation of dynamic MR images

Magnetic resonance imaging (MRI) has been used to study the movement of the tongue tip which is involved in the production of dental consonants. We evaluated its velocity using two independent approaches 13. The first one consists in acquisition with a real-time technique in the mid-sagittal plane. Tracking of the tongue tip manually and with a computer vision method allows its trajectory to be found and the velocity to be calculated. The second approach - phase contrast MRI - enables velocities of the moving tissues to be measured directly. Evaluation on data from two French-speaking subjects articulating /tata/ shows that both methods are in qualitative agreement and consistent with other techniques used for evaluation of the tongue tip velocity.

Tongue contour extraction from real-time MRI is a nontrivial task due to the presence of artifacts (as blurring or ghostly contours). In this work, the automatic tongue delineation is achieved by means of a U-Net auto-encoder convolutional neural network. We particularly investigated both intra- and inter-subject validation using real-time MRI and manually annotated 1-pixel wide contours. Predicted probability maps were post-processed in order to obtain 1-pixel wide tongue contours. The results are very good and slightly outperform published results on automatic tongue segmentation 14.

We investigated the creation a 3D dynamic atlas of the vocal tract that captures the dynamics of the articulators in all three dimensions in order to create a generic speaker model. The core steps of the proposed method are temporal alignment of the real-time MRI acquired in several sagittal planes and their combination with adaptive kernel regression 30, 31. As a preprocessing step, a reference space is created and used to remove anatomical speaker specificities, thus keeping only the variability in speech production for the construction of the atlas 33, 32. The adaptive kernel regression addresses the choice of atlas time points independently of the time points of the frames that are used as an input for the atlas construction. The evaluation with data from two new speakers showed that the use of the atlas helps in reducing subject variability, can capture the dynamic behavior of the articulators and is able to generalize the speech production process by creating a universal-speaker reference space.

Multimodal coarticulation modeling

We have investigated labial coarticulation to animate a virtual face from speech. We have used phonetic information as input to ensure speaker independence. We used a Recurrent Neural Network (RNN), more specifically Gated Recurrent Units (GRU), to account for the dynamics of the articulation which is an essential point of the model. The initialization of the last layers of the network has greatly eased the training and helped to handle coarticulation. It relies on dimensionality reduction strategies, which have allowed us to inject knowledge of a useful latent representation of the visual data into the network. The robustness of the RNNs allowed us to predict lip movements for French and German, and tongue movements for English and German. The evaluation of the model was carried out by means of objective measurements of the quality of the trajectories and by evaluating the realization of the critical articulatory targets. We also conducted a subjective evaluation of the quality of the lip animation of the talking head.

Identifying disfluency in stuttered speech

Within the ANR project BENEPHIDIRE, the goal is to automatically identify typical kinds of stuttering disfluency using acoustic and visual cues for their automatic detection. This year, we started working on existing stuttering acoustic speech datasets. We proposed to use a Time Delay Neural Network (TDNN) model for stuttering identification which takes into consideration the temporal evolution of the acoustic signal of the stuttered speech. We have also started collecting French audiovisual data of subjects who stutter. However the current sanitary context has slowed down this procedure. We are working on alternative remote recording protocols.

8.2.2 Multimodal expressive speech

Arabic speech synthesis

We have continued working on Modern Standard Arabic text-to-speech synthesis with ENIT (École Nationale d’Ingénieurs de Tunis, Tunisia), using HMM and neural network based approaches 87. We have also investigated deep learning modeling of the sound durations for Arabic speech synthesis taking into account specificities of the Arabic language such as vowel quantity and gemination 20.

Expressive audiovisual synthesis

After having acquired a high quality expressive audio-visual corpus based on fine linguistic analysis, motion capture, and naturalistic acting techniques, we have analyzed, processed, and phonetically aligned it with speech 9, 70. We used conditional variational autoencoders (CVAE) to generate the duration, acoustic and visual aspects of speech. The emotion clusters in the latent space were clearly distinguishable although the training was carried on without using emotion labels. Perceptual experiments have confirmed the capacity of our system to generate recognizable emotions. Moreover, the generative nature of the CVAE allowed us to generate well-perceived nuances of the six emotions and to blend different emotions together. The PhD thesis related to these works has been defended 85.

8.2.3 Categorization of sounds and prosody

Non-native speech production

The voicing contrast is realized differently in German and in French, either in the phonetic dimension or in the phonological one, and voicing assimilations appear in opposite direction in these two languages (regressive assimilation in French, progressive in German). We have designed a corpus devoted to the analysis of assimilations made by French people learning German, and the determination of possible links between various aspects of German voicing mastery in French/German productions. We have recorded, segmented and analysed 20 French people learning German.

A corpus of a series of German fricatives have been designed and recorded with the articulograph of the laboratory by four speakers (one German and three French speakers).

Language and reading acquisition by children having some language impairments

We continued investigating the acquisition of language by hard of hearing children via cued speech. In cooperation with DevAH-EA3450 (Univ de Lorraine), we have devised a protocol to examine the use of a digital book and of a children’s picture book for hard-of-hearing children in order to compare scaffolding by the speech therapist or the teacher in these two situations. We also questioned nearly two thousand kindergarten teachers regarding their use of visual language encoding gestures strengthening spoken French Language. The 493 answers received show that teachers use both gestures, French Sign Language or Signed Supported French, with children who don’t have hearing loss more than with deaf children with the aim of developing a better communicational base.

We started examining the intelligibility of the talking head developed by MULTISPEECH. We undertook a scoping study comparing three different modalities: a talking head, a human speaker and a strictly auditory modality. First qualitative results from 8 children with deafnes showed that the avatar, which provides additional visual cues, allows for faster and better understanding of sentences, and was most appreciated by the children.

Computer assisted language learning

The goal of the METAL project is to provide tools to assist in foreign language pronunciation learning. We have developed a web-based learning platform that presents tutoring aspects illustrated by a talking head to show proper articulation of words and sentences; as well as using automatic tools derived from speech recognition technology, for analyzing student pronunciations. The web application is almost finished and will be used by teachers to prepare pronunciation lessons, and by secondary school students learning German. The analysis of student pronunciation is still not completed, and more development will be continued.

The ALOE project dealt with children learning to read. In this project, we were involved with tutoring aspects based on a talking head, and with grapheme-to-phoneme conversion which is a critical tool for the development of the digitized version of ALOE reading learning tools (tools which were previously developed and offered only in a paper form). We have developed a text coder, which predicts the pronunciation of French sentences and returns the alignment between the letters and the sounds.

Prosody

Prosodic correlates of a few discourse particles have been investigated further. In particular prosodic correlates of pragmatic functions have been compared accross languages (French and English) on prepared speech 72, and accross various speech styles 44.

8.3 Speech in its environment

Participants: Emmanuel Vincent, Denis Jouvet, Antoine Deleforge, Dominique Fohr, Mostafa Sadeghi, Md Sahidullah, Irène Illina, Odile Mella, Romain Serizel, Tulika Bose, Guillaume Carbajal, Diego Di Carlo, Stephane Dilungana, Sandipana Dowerah, Ashwin Geet Dsa, Raphaël Duroselle, Nicolas Furnon, Xuechen Liu, Mohamed Amine Menacer, Mauricio Michel Olvera Zambrano, Sunit Sivasankaran, Prerak Srivastava, Nicolas Turpault, Nicolas Zampieri, Ismaël Bada, Joris Cosentino, Louis Delebecque, Mathieu Hu, Stephane Level, Krist Kostallari, Francesca Ronchini.

8.3.1 Acoustic environment analysis

Sound event detection is the task of finding what sound event occurred in a recording and when. As it is prohibitive to get a large dataset with so-called strong labeled soundcases (i.e., with onset and offset timestamps), one alternative is to rely on so-called weakly labeled soundscapes (i.e., without timestamps) that are considerably cheaper to obtain. We explored the limitations introduced by relying only on such weak labels 65. Another alternative would be to generate synthetic soundscapes for which strong annotations are then cheap to obtain but a the cost of possible domain mismatch with recorded evaluation data. We studied the impact of training a sound event detection system using a heterogeneous dataset (including both recorded and synthetic soundscapes) and different label granularity (strong, weak) 64. An additional problem when working with real, complex soundscapes is that they can involve multiple overlapping sound events. We proposed to adapt a standard sound separation algorithm and used it as a front-end to sound event detection on such complex soundscapes 50.

Pursuing our involvement in the community on ambient sound recognition, we co-organized a task on sound event detection and separation as part of the Detection and Classification of Acoustic Scenes and Events (DCASE) 2020 Challenge 64, 66 and published a detailed analysis of the submissions to the previous iteration of this task in 2019 54. In 2020, the task still focused on the problem of learning from audio segments that are either weakly labeled or unlabeled, targeting domestic applications. We also proposed to investigate possible improvement obtained with a sound separation front-end used jointly with sound event detection in the case of complex soundscapes 66. This additional aspect attracted researchers from the sound separation community, including some researchers from the team (not involved in the task organization) who proposed two different approaches to combine sound event detection and sound separation 25, 24.

We also pursued our work in estimating acoustical properties of environments from recorded audio, e.g., room shape, reverberation time or absorption coefficients. Much of the information is contained in early acoustic echoes, stemming from the sound interaction with reflective materials in the room. A new anaytical method for blind early acoustic echo retrieval based on the framework of continuous dictionary learning was proposed in 29. A new approach for mean absorption coefficient estimation from impulse reponses using virtually-supervised learning was presented in 22.

8.3.2 Speech enhancement and noise robustness

Sound source localization and counting

We studied the problem of detecting the activity and counting overlapping speakers in distant-microphone recordings 26. We proposed to treat supervised voice activity detection, overlapped speech detection, and speaker counting as instances of a general supervised classification task. We designed a temporal convolutional network (TCN) based method to address it and showed that it significantly outperforms state-of-the-art methods on two real-world distant speech datasets.

Speech enhancement

We pursused our investigation of multichannel speech separation. We proposed a deflation method which iteratively estimates the location of one speaker, derives the corresponding time-frequency mask and removes the estimated source from the mixture before estimating the next one 58. Sunit Sivasankaran successfully defended his PhD on this topic 88.

We also finalized our work on joint reduction of acoustic echo, reverberation and noise. Our method models the target and residual signals after linear echo cancellation and dereverberation using a multichannel Gaussian modeling framework and jointly represents their spectra by means of a neural network. We developed an iterative block-coordinate ascent algorithm to update all the filters. The proposed approach outperforms in terms of overall distortion a cascade of the individual approaches and a joint reduction approach which does not rely on a spectral model of the target and residual signals 6. Guillaume Carbajal successfully defended his PhD on this topic 84.

In the context of ad-hoc acoustic antennas, we proposed to extend the distributed adaptive node-specific signal estimation approach to a neural network framework. At each node, a local filtering is performed to send one signal to the other nodes where a mask is estimated by a neural network in order to compute a global multi-channel Wiener filter. In an array of two nodes, we showed that this additional signal can be efficiently taken into account to predict the masks and leads to better speech enhancement performance than when the mask estimation relies only on the local signals 37, 38, 76. We also proposed an extension of the approach to speech separation from several concurrent speakers 91.

Robust speech recognition

Achieving robust speech recognition in reverberant, noisy, multi-source conditions requires not only speech enhancement and separation but also robust acoustic modeling. In order to motivate further work by the community, we created the series of CHiME Speech Separation and Recognition Challenges in 2011. This year, we organized the 6th edition of the Challenge 67. Compared to the 5th edition, we introduced a second track, which is the first challenge activity in the community to tackle an unsegmented multispeaker speech recognition scenario with a complete set of reproducible open source baselines providing speech enhancement, speaker diarization, and speech recognition modules.

In the framework of the MMT project, we have revised two methods that take into account the uncertainty, that is the variance of the residual distortion of speech after enhancement: the DNNU method which propagates the uncertainty through the acoustic models and the GMMD method which modifies the acoustic vectors. Evaluations were carried on the TED corpus with additive noises and on 2 corpora close to our aeronautical application. We evaluated different acoustic models: the noiseless model, the noisy model and the noisy and enhanced model. The experimental results show that on the TED corpus, the GMMD uncertainty method with the noisy and enhanced model improves recognition results compared to the other models studied.

Speaker recognition

Developing a robust speaker recognition system remains a challenging task due to the variations in environmental conditions, channel effect, speakers’ intrinsic characteristics, etc. To improve robustness, we have investigated a data-driven acoustic feature extraction method 18. We have explored statistical methods to compute optimal filterbank parameters such as the frequency warping scale and filter shape from the audio dataset. The proposed scheme showed considerable improvement over the popular handcrafted feature such as mel-frequency cepstral coefficients (MFCCs) for clean and noisy conditions. Acoustic front-ends developed for improving robustness in a statistical speaker recognition framework were not investigated so far in a deep learning framework. In 46, we compared different acoustic front-ends for deep speaker embeddings. Our extensive study revealed that robust speech features involving long-term processing are more effective than commonly used MFCCs, especially in noisy conditions. Our study also demonstrates the potentiality of phase-based features for robust deep speaker embeddings. In another work 47, we explored learnable MFCCs where differentiable units replace all the linear modules of the MFCC processing chain. The results indicate that learnable MFCCs are substantially better than MFCCs computed with fixed parameters.

We have also participated in the first short-duration speaker verification (SdSV) challenge, where the key problem was to recognize speakers from short-duration utterances spoken in varying channel conditions 53. Our study demonstrates that phonetic bottleneck features are promising for text-dependent speaker recognition. Our final submission to the challenge ranked fifth among 20 submissions in the text-dependent subtask of the challenge. We have also participated in the third DIHARD challenge, where the key problem was the speaker diarization on audio-data collected from diverse real-world conditions. We have substantially improved the challenge baseline system by integrating domain-identification and domain-dependent processing 74.

Speaker recognition systems are highly prone to the spoofing attacks performed with voice conversion and speech synthesis technology 19, 16. The spoofing is more prevalent due to the recent technological advancements in creating fake media contents popularly known as deepfakes. In a recent study 17, we have demonstrated that spoofing detection becomes a more challenging task when a natural speech signal is augmented with a small portion of synthetic speech. We have proposed a solution with frame-selection, which substantially improves the spoofing detection performance for such a scenario.

Language identification

State-of-the-art spoken language identification systems consist of three modules: a frame level feature extractor, a segment level embedding extractor and a classifier. The performance of these systems degrades when facing mismatch between training and testing data. Although most domain adaptation methods focus on adaptation of the classifier, we have developed an unsupervised domain adaptation method for the embedding extractor. The proposed approach consists in adding a regularisation term in the loss function used for training the segment level embedding extractor. Experiments were conducted with respect to transmission channel mismatch between telephone and radio channels using the RATS corpus. The proposed method is superior to adaptation of the classifier and perform on par with published language identification approaches but without using labelled data from the target domain 71, 34. Another approach has been investigated to control the domain missmatch, which relies on combining a classification loss with the metric learning n-pair loss for training the x-vector DNN model. Such a system achieves comparable robustness to a system trained with a domain adaptation loss function but without using the domain information 35.

These DNN based approaches for language identification have been combined with a conventional Gaussian mixture model approach, and the resulting system has been ranked first for cross channel language recognition, and for noisy data language identification at the Oriental Language Recognition challenge (OLR 2020).

8.3.3 Linguistic and semantic processing

Transcription, translation, summarization and comparison of videos

Within the AMIS project, we studied different subjects related to the processing of videos. One objective of the project was to summarize videos (for example in Arabic) into a target language (for example English). The demonstrator exploits research carried on in several areas including video summarization, speech recognition, machine translation, audio summarization 21.

Detection of hate speech in social media

The spectacular expansion of the Internet led to the development of a new research problem in natural language processing, the automatic detection of hate speech, since many countries prohibit hate speech in public media. In the context of the M-PHASIS project, we explored a label propagation-based semi-supervised learning system for the task of hate speech classification. We showed that pre-trained representations are label agnostic, and when used with label propagation yield poor results. Neural network-based fine-tuning was adopted to learn task-specific representations using a small amount of labeled data 28.

We also designed binary classification and regression-based approaches aiming to determine whether a comment is toxic or not. We compared different unsupervised word representations and different DNN based classifiers. Moreover, we studied the robustness of the proposed approaches to adversarial attacks by adding one (healthy or toxic) word. Our experiments showed that using BERT fine-tuning outperforms feature-based BERT, Mikolov’s and fastText representations with different DNN classifiers 392711.

In the framework of the M-PHASIS project, a new hate speech corpus has been created. More than 8,000 comments (about 4,000 in French and 4,000 in German) have been collected on News websites and manually annotated.

Introduction of semantic information in an automatic speech recognition system

Current Automatic Speech Recognition (ASR) systems mainly take into account acoustic, lexical and local syntactic information. Long term semantic relations are not used. The ASR performance significantly degrades when the training and testing conditions differ due to noise, etc. In this case the acoustic information can be less reliable. To improve performance in such conditions, we propose to supplement the ASR system with a semantic module. This module re-evaluates the N-best list of ASR hypotheses and can be seen as a form of adaptation in the context of noise. Words in the processed sentence that could have been poorly recognized are replaced by words that better correspond to the semantic context of the sentence. To achieve this, we introduced the notions of a context part and possibility zones that measure the similarity between the semantic context of the document and the corresponding possible hypotheses. We conducted experiments on the publicly available TED conferences dataset (TED-LIUM) mixed with real noise. The proposed method achieves a significant reduction of the word error rate (WER) over the ASR system without using semantic information 457573.
