Abstract
We have developed the real-time speech visualization system called “KanNon” [1], which supports speech communication of hearing-impaired people. The KanNon system presents informations of the speech such as loudness, pitch, sound spectrogram and characters by speech recognition system in real-time.Furthermore we have attempted to develop the vowels recognition system which recognizes phonemes of speeches. For this purpose, in this paper, we develop a method for distinction of phoneme sections and we propose two discrimination indices of dividing phonemes. Finally, we show experimental results of discrimination of phoneme sections as well as the recognition of phonemes.
