Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for hotword detection on multiple devices are disclosed. In one aspect, a method includes the actions of receiving, by a first computing device, audio data that corresponds to an utterance. The actions further include determining a first value corresponding to a likelihood that the utterance includes a hotword. The actions further include receiving a second value corresponding to a likelihood that the utterance includes the hotword, the second value being determined by a second computing device. The actions further include comparing the first value and the second value. The actions further include based on comparing the first value to the second value, initiating speech recognition processing on the audio data.
Claims18
A computer-implemented method comprising:
- receiving, by a computing device that is in a low power mode, audio data that includes an utterance of a particular, predefined hotword;
- while the computing device remains in the low power mode, and in response to receiving the audio data that includes the utterance of the particular, predefined hotword, transmitting, by the computing device, a message;
- while the computing device remains in the low power mode, receiving, by the computing device and from an additional computing device that is in a low power mode, an additional message;
- and
- based on the message and the additional message, determining, by the computing device, to exit the low power mode.
A system comprising:
- one or more computers;
- and
- one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
- receiving, by a computing device that is in a low power mode, audio data that includes an utterance of a particular, predefined hotword;
- while the computing device remains in the low power mode, and in response to receiving the audio data that includes the utterance of the particular, predefined hotword, transmitting, by the computing device, a message;
- while the computing device remains in the low power mode, receiving, by the computing device and from an additional computing device that is in a low power mode, an additional message;
- and
- based on the message and the additional message, determining, by the computing device, to exit the low power mode.
A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:
- receiving, by a computing device that is in a low power mode, audio data that includes an utterance of a particular, predefined hotword;
- while the computing device remains in the low power mode, and in response to receiving the audio data that includes the utterance of the particular, predefined hotword, transmitting, by the computing device, a message;
- while the computing device remains in the low power mode, receiving, by the computing device and from an additional computing device that is in a low power mode, an additional message;
- and
- based on the message and the additional message, determining, by the computing device, to exit the low power mode.
