    • A small array microphone system includes an array microphone having a plurality of microphones and operative to provide a plurality of received signals, each microphone providing one received signal. A first voice activity detector (VAD) provides a first voice detection signal generated using the plurality of received signals to indicate the presence or absence of in-beam desired speech. A second VAD provides a second voice detection signal generated using the plurality of received signals to indicate the presence or absence of out-of-beam noise when in-beam desired speech is absent. A reference signal generator provides a reference signal based on the first voice detection signal, the plurality of received signals, and a beamformed signal, wherein the reference signal has the desired speech suppressed. A beamformer provides the beamformed signal based on the second voice detection signal, the reference signal, and the plurality of received signals, wherein the beamformed signal has noise suppressed. A multi-channel noise suppressor operative to further suppress noise in the beamformed signal and provide an output signal. A speech reliability detector provides a reliability detection signal indicating the reliability of each frequency subband. The first voice detection signal, the second voice detection signal, the reliability detection signal and the output signal are provided to the speech recognition engine.
    • 小阵列麦克风系统包括具有多个麦克风并且可操作以提供多个接收信号的阵列麦克风,每个麦克风提供一个接收的信号。 第一语音活动检测器(VAD)提供使用多个接收信号产生的第一语音检测信号,以指示波束内期望语音的存在或不存在。 第二VAD提供使用多个接收信号产生的第二语音检测信号,以在不存在束内期望语音时指示出射外噪声的存在或不存在。 参考信号发生器基于第一语音检测信号,多个接收信号和波束形成信号提供参考信号,其中参考信号具有所需的语音抑制。 波束形成器基于第二语音检测信号,参考信号和多个接收信号提供波束形成信号,其中波束形成的信号被抑制噪声。 一种多声道噪声抑制器,用于进一步抑制波束形成信号中的噪声并提供输出信号。 语音可靠性检测器提供表示每个频率子带的可靠性的可靠性检测信号。 第一语音检测信号,第二语音检测信号,可靠性检测信号和输出信号被提供给语音识别引擎。

    • A hands-free voice communication apparatus with integrated speakerphone and earpiece is described. The speakerphone includes a loudspeaker and zero, one or multiple microphones. The earpiece includes a small loudspeaker, one or more microphones, a wireless module, and a digital signal processing (DSP) module. The hands-free device support hands-free voice communication via the speakerphone or the earpiece. The earpiece is functional when removed from the speakerphone case and may be used for voice communication with privacy. When the earpiece is placed back in the speakerphone case, the speakerphone is functional and may be used for voice communication with convenience. The DSP module performs digital signal processing for both the earpiece and the speakerphone, e.g., using different sets of parameters. The speakerphone may be a standalone device or may be part of a communication device. The wireless module communicates with the communication device, which provide end-to-end communication with a far-end user.
    • 描述了具有集成扬声器和耳机的免提语音通信装置。 扬声器包括扬声器和零个,一个或多个麦克风。 听筒包括一个小型扬声器,一个或多个麦克风,无线模块和数字信号处理(DSP)模块。 免提设备通过扬声器或耳机支持免提语音通信。 从扬声器外壳中取出时,耳机功能正常,可用于隐私的语音通信。 当耳机放回扬声器外壳时,扬声器功能正常,可方便地用于语音通信。 DSP模块对耳机和扬声器电话进行数字信号处理,例如使用不同的参数组。 扬声器可以是独立设备,也可以是通信设备的一部分。 无线模块与通信设备通信,该通信设备提供与远端用户的端到端通信。

    • The invention provides an Internet communication device. The Internet communication device plays a remote audio signal received via a network and transmits an audio signal back to the remote party to complete the communication. The Internet communication device comprises a line-in speech detection module and a line-in channel control module. The line-in speech detection module detects whether the remote audio signal is speech or not to generate a remote speech detection result. The line-in channel control module then attenuates the remote audio signal if the remote speech detection result indicates that the remote audio signal is not speech, thus, all noise including non-stationary noise is removed from the remote audio signal.
    • 本发明提供一种因特网通信设备。 互联网通信设备播放通过网络接收到的远程音频信号,并将音频信号发送回对方以完成通信。 互联网通信设备包括线路输入语音检测模块和线路输入信道控制模块。 线路输入语音检测模块检测远程音频信号是否是语音,以产生远程语音检测结果。 如果远程语音检测结果指示远程音频信号不是语音,则线路输入信道控制模块会衰减远程音频信号,从而从远程音频信号中去除包括非平稳噪声的所有噪声。
