Keywords : speech modeling, speech recognition, broadcast news indexing, beam-search.

Speech recognition search engine, Sirocco

Participant : Guillaume Gravier.

In collaboration with the computer science dept. at ENST, METISS actively participates in the development of the freely available Sirocco large vocabulary speech recognition software [48] based on the algorithm described in [60]. The Sirocco project started as an INRIA Concerted Research Action now works on the basis of voluntary contributions.

In the METISS group, the Sirocco speech recognition software is used to validate algorithms within an entire indexing system. In particular, it has been used to study noise robustness of speech recognition using source separation techniques [38]. We are also currently using Sirocco as the heart of a broadcast news indexing system to illustrate the know-how of METISS in terms of segmentation into sound classes and into speakers. Our broadcast news indexing system will be evaluated in the framework of the national evaluation campaign ESTER (Broadcast News Rich Transcription System Evaluation).
