To quickly detect an utterance direction of a prescribed word (for example, a wake-up word or the like) uttered in a vehicle, and exclusively extract a voice uttered by a speaker of the prescribed word following the prescribed word, with respect to voices other than that of the speaker.SOLUTION: In a voice processing device, a voice control part 140 includes: a speaker position detection part 143 for identifying as a speaker position microphone among microphones MC1-MC6, a microphone picking up a sound signal of WuW on the basis of respective characteristics of a voice signal for a prescribed time period held in a voice signal buffer part 142 when a voice of WuW is detected; and a CTC part (an example of a voice processing part) 144 for outputting a voice uttered by a speaker by using the voice signal for the prescribed time period held in the buffer part 142 as well as information on the speaker position microphone, while inhibiting voices uttered by occupants other than the speaker.SELECTED DRAWING: Figure 3

    【課題】車両内で発声される所定ワード(例えば、ウェイクアップワード等)の発声方向を迅速に検出し、その所定ワードの話者が所定ワードに続けて発声する音声をその話者以外の音声に対して排他的に抽出する。【解決手段】音声処理装置において、音声制御部140は、WuWの音声が検出された場合に、音声信号バッファ部142に保持される所定時間分の音声信号のそれぞれの特性に基づいて、WuWの音声信号を収音したマイクMC1〜MC6を話者位置マイクとして特定する話者位置検出部143と、音声信号バッファ部142に保持される所定時間分の音声信号と話者位置マイクに関する情報とを用いて、話者が発声した音声を出力するとともに、話者でない乗員が発声した音声を抑圧するCTC部(音声処理部の一例)144とを備える。【選択図】図3
