PROBLEM TO BE SOLVED: To provide a voice collection device and voice collection device control method for facilitating the highly accurate acquisition of the voice of an utterer while reducing the number of components and suppressing the complication of a structure.SOLUTION: Whether an operation mode is the operation mode (an utterance mode or a speech mode) for acquiring the voice of a crew member being an utterer or not is determined (step S1A). When the operation mode is the other operation mode (a voice reproduction mode or a head position measurement mode), the directivity of a microphone array is set to be an outer side of the crew member or to be non-directional (steps S4A, S5A), so as to acquire the input voice of the microphone array. When the operation mode is the operation mode (the utterance mode or the speech mode) for acquiring the voice of the crew member, the directivity of the microphone array is directed to the crew member (step S2A).SELECTED DRAWING: Figure 6
【課題】部品点数の低減や構造の複雑化を抑えつつ、発話者の音声を高精度に取得し易い集音装置、及び集音装置の制御方法を提供する。【解決手段】発話者である乗員の音声を取得する動作モード(発話モード、通話モード)か否かを判定し(ステップS1A)、他の動作モード(音声再生モード、頭部位置測定モード)であった場合に、マイクアレイの指向性を乗員の外側、又は無指向に設定し(ステップS4A、S5A)、マイクアレイの入力音声を取得し、乗員の音声を取得する動作モード(発話モード、通話モード)の場合に、マイクアレイの指向性を乗員に向けるようにした(ステップS2A)。【選択図】図6
