| 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 the speech tends to become unstable due to strain of a muscle and that causes degradation of speech recognition. In this paper, we focus on the fact that recognition rate of a person with an articulation disorder decreases compared with that of a physically unimpaired person, expecially in speech recognition using dynamic features only. Therefore, we use multiple acoustic frames as an acoustic feature to solve this problem. Its effectiveness is confirmed by word recognition experiments. |
