Abstract
Techniques for processing incoming audio using multiple wakeword detectors are described. Audio data representing an utterance may be processed by different wakeword detectors that can detect different wakewords and are associated with different speech processing components. When a wakeword is detected by one of the wakeword detectors, it may be processed by the corresponding speech processing component.
Claims20
A computer-implemented method, comprising:
- receiving first audio data corresponding to an utterance;
- processing the first audio data using:
- a first wakeword detection component configured to detect a representation of at least a first wakeword, the first wakeword detection component being associated with a first speech processing component, and
- a second wakeword detection component configured to detect a representation of at least a second wakeword different from the first wakeword, the second wakeword detection component being associated with a second speech processing component;
- determining the utterance includes the first wakeword;
- and
- causing the first speech processing component to process further audio data.
4 more elements
A system comprising:
- at least one processor;
- and
- at least one memory comprising instructions that, when executed by the at least one processor, cause the system to:
- receive first audio data corresponding to an utterance;
- process the first audio data using:
- a first wakeword detection component configured to detect a representation of at least a first wakeword, the first wakeword detection component being associated with a first speech processing component, and
- a second wakeword detection component configured to detect a representation of at least a second wakeword different from the first wakeword, the second wakeword detection component being associated with a second speech processing component;
- determine the utterance includes the first wakeword;
- and
- cause the first speech processing component to process further audio data.
7 more elements
A computer-implemented method, comprising:
- receiving first audio data corresponding to an utterance;
- processing the first audio data using a first wakeword detection component to determine that the utterance includes at least a first wakeword;
- at least partially in response to determining that the utterance includes the first wakeword, using a second wakeword detection component different from the first wakeword detection component to determine that the utterance includes at least a second wakeword;
- and
- based at least in part on determining that the utterance includes the second wakeword, causing a speech processing component associated with the second wakeword to process further audio data.
