摘要： Natural language controlled devices may be configured to activate command recognition in response to one or more wake words. Techniques are provided to allow for multiple operating modes in which different recognition parameters are employed in recognizing wake words that activate the natural language control functionality of a computing device.

摘要： An audio device may be configured to produce output audio and to capture input audio for speech recognition. In some cases, a second device may also be used to capture input audio to improve isolation of input audio with respect to the output audio. In addition, acoustic echo cancellation (AEC) may be used to remove components of output audio from input signals of the first and second devices. AEC may be implemented by an adaptive filter based on dynamically optimized filter coefficients. The filter coefficients may be analyzed to detect situations in which the first and second devices are too close to each other, and the user may then be prompted to increase the distance between the two devices.

摘要： Techniques for using both speaker-identification information and other characteristics associated with received voice commands to determine how and whether to respond to the received voice commands. A user may interact with a device through speech by providing voice commands. After beginning an interaction with the user, the device may detect subsequent speech, which may originate from the user, from another user, or from another source. The device may then use speaker-identification information and other characteristics associated with the speech to attempt to determine whether or not the user interacting with the device uttered the speech. The device may then interpret the speech as a valid voice command and may perform a corresponding operation in response to determining that the user did indeed utter the speech. If the device determines that the user did not utter the speech, however, then the device may refrain from taking action on the speech.
摘要翻译：用于使用扬声器识别信息和与接收到的语音命令相关联的其它特征的技术来确定如何以及是否响应于所接收的语音命令。用户可以通过提供语音命令通过语音与设备交互。在开始与用户的交互之后，设备可以检测来自用户的后续语音，来自另一个用户，或从另一个源。然后，设备可以使用与语音相关联的扬声器识别信息和其他特征来尝试确定用户与设备进行交互是否发出语音。然后，设备可以将该语音解释为有效的语音命令，并且可以响应于确定用户确实发出语音来执行相应的操作。然而，如果设备确定用户没有发出该语音，则设备可以不对该语音采取行动。
