ECU (environmental control unit) takes an important role in self-support for developmentally-disabled individual. Some ECU use speech recognition for operation. It is important for a crippled-disabled person to use speech recognition. However, it is very difficult for a person with articulation disorder to use the ECU with speech interface since conventional ECU targets non-articulation disorder as user. Our subject is to build the ECU which can recognize articulation disorder’s speech. In this paper, we built an acoustic model for a person with articulation disorder and evaluated speech recogniton in the task of operation for home information appliances. We used two different speech data as test data. One is recorded under a familiar environment. The other is recorded under an unfamiliar environment. In the experiment for speech data which recorded under the unfamiliar environment, the word-recognition rate of 56.4% was obtained. The speaking style of a person with cerebral palsy tends to fluctuate by the change of environments. Therefore, we carried out speaker adaptation in the test environment, and the word-recognition rate improved to 83.9%. |
