| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Since body-conducted speech has a noise-robust characteristic under noise environment, noise-robust speech recognition systems using body-conducted speech are expected. However, body-conducted signal can not capture characteristics of high-frequency sounds sufficiently. In conventional methods to improve quality of body– conducted speech, both speech and body-conducted speech are needed. On the other hand, we propose a method using only a differential acceleration of body-conducted speech and conventional noise reduction methods. Results of isolated word recognition experiments have shown significant effectiveness of the methods. |
