概要

• 論文の詳細を見る

• For some applications such as hands-free teleconferencing and telecommunication systems, the near-end speech signal to be transmitted is disturbed by ambient noise and by an echo due to the coupling between the microphone and the loudspeaker. In the present paper, we introduce a new approach using echo cancellation and Maximum A Posteriori(MAP)environmental adaptation technique to improve hands-free speech recognition accuracy. In this approach, it is shown that our proposed new system is effective for hands-free speech recognition in the echo and noise environments.
