Noëlle Carbonell, Dominique Fohr, Jean‐Paul Haton · International Journal of Pattern Recognition and Artificial Intelligence · 1987
The acoustic-phonetic decoding of sentences is a major bottleneck in continuous speech recognition. Our group has been working in this area for the past twelve years. In order to improve the accuracy of present phonetic decoders, we are now developing an expert system called APHODEX that should emulate the competence of an experienced spectrogram reader. After a brief description of the methodology used to elucidate the expert's knowledge and strategies, we focus on the expert's approach and results. Finally we explain how this expertise has been implemented; some results from the present experimental version of our system are given.
