| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A language generally has several tens of phonemes. Acoustic substances of the phoneme depend upon its phonemic environment and the context-sensitive phonemes are called allophones. The number of the allophones in a language is naturally much larger than that of the phonemes. Although the allophones represent finer acoustic differences between linguistic sounds, it is very strange that they completely ignore the acoustic variations in an allophone caused by differences in age, gender, microphone, room, etc. The triphones, which are acoustic models widely used in speech recognition, correspond to the allophones and the ignorance of the acoustic variations caused by the non-linguistic factors are implemented by collecting speech samples from an enormous number of speakers and training statistical acoustic models of the individual allophones. In this paper, it is mathematically shown that the ignorance can be realized not by collecting samples but by capturing timbral differences between two sounds. Then, the possibility of speaker-independent speech recognition only with a very small number of training speakers is experimentally examined. In the proposed framework, what is modeled is not the elementary sound substances, i.e., reductionism, but the holistic sound system exclusively composed of the timbral differences, i.e., holism. | |
