| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In order to provide an efficient means of communication for those who cannot move muscles of their whole body except eyes due to amyotrophic lateral sclerosis (ALS), we are studying a speech synthesis interface based on electrooculogram (EOG) input. The system consists of an EOG input module, an eye motion recognizer, and a speech synthesizer. In this paper, we improve the EOG input based eye motion recognizer applying speech recognition techniques. In our previous system, a hidden Markov model (HMM) based bi eye-motion model was used. However, it was not enough to effectively model the context effects of eye motions. In this study, we investigate using a tied-state tri eye-motion model. Moreover, an N-gram model is integrated to the recognition system. In the experiment, it is shown that 96.2% of character ecognition accuracy is obtained by using the tri eye-motion model whereas it is 84.3% and 89.1% for mono and bi eye-motion models, respectively. By using a character 3-gram model in combination with the tri eye motion-model, the highest character accuracy of 97.3% has been obtained. | |
