Abstract: Techniques for indicating to a voice-controlled device that a user is going to provide a voice command to the device. In response to receiving such an indication, the device may prepare to process an audio signal based on sound captured by a microphone of the device for the purpose of identifying the voice command from the audio signal. For instance, a user may utilize a signaling device that includes a button that, when actuated, sends a signal that is received by the voice-controlled device. In response to receiving the signal, a microphone of the voice-controlled device may capture sound that is proximate to the voice-controlled device and may create an audio signal based on the sound. The voice-controlled device may then analyze the audio signal for a voice command of the user or may provide the audio signal to a remote service for identifying the command.

Abstract: A speech recognition platform configured to receive an audio signal that includes speech from a user and perform automatic speech recognition (ASR) on the audio signal to identify ASR results. The platform may identify: (i) a domain of a voice command within the speech based on the ASR results and based on context information associated with the speech or the user, and (ii) an intent of the voice command. In response to identifying the intent, the platform may perform a corresponding action, such as streaming audio to the device, setting a reminder for the user, purchasing an item on behalf of the user, making a reservation for the user or launching an application for the user. The speech recognition platform, in combination with the device, may therefore facilitate efficient interactions between the user and a voice-controlled device.
