Outline of Final Research Achievements

We proposed a speech support system using body-conducted speech recognition. This system retrieves speech from body-conducted sound via a transfer function, using recognition to select a sub-word sequence and its duration. In this study, we demonstrate the effectiveness of producing clear body-conducted speech using a linear predictive coefficient instead of a transfer function and used continuous sub-word recognition automatically. To confirm the improvement in synthesized speech, a jury test and articulatory feature analysis were employed. Then we confirmed the lost informations involving disabled were recovered with these methods. Practical tablet system was developed and got a good evaluation by disorders. And a database of speech disorders was also constructed.
