DEVICE-DIRECTED UTTERANCE DETECTION

Abstract: a speech interface device is configured to detect an interrupt event and process a voice command without detecting a wakeword. the device includes on-device interrupt architecture configured to detect when device-directed speech is present and send audio data to a remote system for speech processing. this architecture includes an interrupt detector that detects an interrupt event (e.g., device-directed speech) with low latency, enabling the device to quickly lower a volume of output audio and/or perform other actions in response to a potential voice command. in addition, the architecture includes a device directed classifier that processes an entire utterance and corresponding semantic information and detects device-directed speech with high accuracy. using the device directed classifier, the device may reject the interrupt event and increase a volume of the output audio or may accept the interrupt event, causing the output audio to end and performing speech processing on the audio data.
