Abstract

　話者の切替わり時の異音の発生の低減。パワー計算部１１１、・・は、入力音声信号のパワーを計算する。話者選択部２００は、各パワーを元に入力音声信号を選択する。全信号加算器３００は、選択された全ての入力音声信号を加算し、ミキシング音声として加算器１３１、・・および共通雑音抑圧部４００に出力する。共通雑音抑圧部４００は、入力信号の雑音を抑圧して出力する。加算器１３１、・・は、選択された音声信号をミキシング音声から減算して雑音抑圧部１４１、・・に出力する。雑音抑圧部１４１、・・は、入力信号の雑音を抑圧して出力する。メモリ切替器１５１、・・は、話者選択部２００の選択結果を元に共通雑音抑圧部４００の過去の情報を雑音抑圧部１４１、・・にコピーする。音声データ切替器１６１、・・は、話者選択部２００の選択結果を元に出力音声信号を切替える。
