Patent attributes
A device having a voice-based interface activates or “wakes” when it detects an utterance that includes a wakeword. The device includes a digital-signal processor (DSP) that implements a first, lower-power speech-processing component that detects when captured audio includes the wakeword; the first speech-processing component then activates a second, higher-accuracy wakeword detection component that confirms that the captured audio includes the wakeword. The device may configure a wakeword-detection parameter, speaker-identification parameter, and/or wakeword-detection model of the first speech-processing component based on device-use data corresponding to the device, such as an environment of the device and/or a usage pattern of the user of the device.
