ASTALI - Automatic Speech-Text Alignment

Functional Description: ASTALI is a software for aligning a speech signal with its corresponding orthographic transcription (given in simple text file for short audio signals or in .trs files as generated by transcriber for longer speech signals). Using a phonetic lexicon and automatic grapheme-to-phoneme converters, all the potential sequences of phones corresponding to the text are generated. Then, using acoustic models, the tool finds the best phone sequence and provides the boundaries at the phone and at the word levels. The web application makes the service easy to use, without requiring any software downloading. Also, the software is currently under integration in the EQUIPEX ORTOLANG platform.
