| Abstract(in English) | Recently, the accuracy of speaker-independent speech recognition has been remarkably improved by use of stochastic modeling of speech. However, there has been very little research on orally-challenged people, such as those with speech impediments. Therefore we have tried to build the acoustic model for a person with articulation disorders. The articulation of speech tends to become unstable due to strain on speech-related muscles, and that causes degradation of speech recognition. Therefore, we consider temporal dependence to solve this problem. Though HMM makes it possible to recognize clear utterance with high accuracy, the speech including the noise or the continuous utterance causes degradation of speech recognition. To solve this problem, J. Bilmes proposed buried Markov model which contains the conditional independence between the observation nodes. In this paper, we perform phone recognition experiments using buried Markov model. |
