    Abstract: In a mobile device, a bone conduction or vibration sensor is used to detect the user's speech and the resulting output is used as the source for a low power Voice Trigger (VT) circuit that can activate the Automatic Speech Recognition (ASR) of the host device. This invention is applicable to mobile devices such as wearable computers with head mounted displays, mobile phones and wireless headsets and headphones which use speech recognition for the entering of input commands and control. The speech sensor can be a bone conduction microphone used to detect sound vibrations in the skull, or a vibration sensor, used to detect sound pressure vibrations from the user's speech. This VT circuit can be independent of any audio components of the host device and can therefore be designed to consume ultra-low power. Hence, this VT circuit can be active when the host device is in a sleeping state and can be used to wake the host device on detection of speech from the user. This VT circuit will be resistant to outside noise and react solely to the user's voice.

    Abstract translation: 在移动设备中，使用骨传导或振动传感器来检测用户的语音，并且所得到的输出被用作可以激活主机的自动语音识别（ASR）的低功率语音触发（VT）电路的源 设备。 本发明可应用于诸如具有头戴式显示器的可穿戴计算机，移动电话和无线耳机以及使用语音识别来输入输入命令和控制的耳机的移动设备。 语音传感器可以是用于检测颅骨中的声音振动的骨传导麦克风或用于检测来自用户的语音的声压振动的振动传感器。 该VT电路可以独立于主机设备的任何音频组件，因此可以被设计为消耗超低功耗。 因此，当主机处于睡眠状态时，该VT电路可以是活动的，并且可以用于在从用户检测到语音时唤醒主机设备。 该VT电路将抵抗外部噪声，并仅对用户的声音作出反应。
