    • An audio analysis apparatus includes the following components. A strap has an end portion connected to a main body and is used to hang the main body from a user's neck. A first audio acquisition device is at the end portion or in the main body. Second and third audio acquisition devices are at positions separate from the end portion by substantially the same predetermined distances, on the respective sides of the strap extending from the user's neck. An analysis unit discriminates whether an acquired sound is an uttered voice of the user or another person by comparing audio signals of acquired by the first and second or third audio acquisition devices and detects an orientation of the user's face by comparing the audio signals acquired by the second and third audio acquisition devices. A transmission unit transmits the analysis result to an external apparatus.
    • 音频分析装置包括以下部件。 带子具有连接到主体的端部,用于将主体从使用者的脖子上悬挂下来。 第一音频采集装置位于主体的端部或主体。 第二和第三音频采集装置在从用户的颈部延伸的带的相应侧上处于与端部分开大致相同的预定距离的位置。 分析单元通过比较由第一和第二或第三音频获取装置获取的音频信号来鉴别所获取的声音是用户或另一人的发声,并且通过比较由第一和第三音频获取装置获取的音频信号来检测用户的脸部的方位, 第二和第三音频采集设备。 传输单元将分析结果发送到外部设备。

    • A voice analyzer includes a first voice acquisition unit provided in a place where a distance of a sound wave propagation path from a mouth of a user is a first distance, plural second voice acquisition units provided in places where distances of sound wave propagation paths from the mouth of the user are smaller than the first distance, and an identification unit that identifies whether the voices acquired by the first and second voice acquisition units are voices of the user or voices of others excluding the user on the basis of a result of comparison between first sound pressure of a voice signal of the voice acquired by the first voice acquisition unit and second sound pressure calculated from sound pressure of a voice signal of the voice acquired by each of the plural second voice acquisition units.
    • 语音分析器包括:第一语音获取单元,设置在来自用户的口部的声波传播路径的距离为第一距离的位置,多个第二语音获取单元,设置在距离用户的声波传播路径的距离 用户的口径小于第一距离,以及识别单元,其基于第一和第二语音获取单元获取的语音是否基于用户的语音或除了用户之外的其他人的语音,基于 由第一语音获取单元获取的语音的语音信号的第一声压和由多个第二语音获取单元中的每一个获取的语音的语音信号的声压计算的第二声压。
