Hotword detection on multiple devices
First Claim
1. A computer-implemented method comprising:
- receiving, by a computing device that is configured to process voice commands that are preceded by a predefined hotword, audio data;
while receiving the audio data, performing, by the computing device, an operation;
determining, by the computing device, that the audio data includes the predefined hotword and an audio signal indicating that the computing device is to bypass further processing of the audio data;
after determining that the audio data includes the predefined hotword and the audio signal indicating that the computing device is to bypass further processing of the audio data, continuing, by the computing device, to perform the operation; and
in response to determining, by the computing device, that the audio data includes the predefined hotword and the audio signal indicating that the computing device is to bypass further processing of the audio data, bypassing, by the computing device, further processing of the audio data.

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 computing device, audio data that corresponds to an utterance. The actions further include determining a likelihood that the utterance includes a hotword. The actions further include determining a loudness score for the audio data. The actions further include based on the loudness score, determining an amount of delay time. The actions further include, after the amount of delay time has elapsed, transmitting a signal that indicates that the computing device will initiate speech recognition processing on the audio data.

8. A system comprising:
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 configured to process voice commands that are preceded by a predefined hotword, audio data; while receiving the audio data, performing, by the computing device, an operation; determining, by the computing device, that the audio data includes the predefined hotword and an audio signal indicating that the computing device is to bypass further processing of the audio data; after determining that the audio data includes the predefined hotword and the audio signal indicating that the computing device is to bypass further processing of the audio data, continuing, by the computing device, to perform the operation; and in response to determining, by the computing device, that the audio data includes the predefined hotword and the audio signal indicating that the computing device is to bypass further processing of the audio data, bypassing, by the computing device, further processing of the audio data. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. 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 configured to process voice commands that are preceded by a predefined hotword, audio data; while receiving the audio data, performing, by the computing device, an operation; determining, by the computing device, that the audio data includes the predefined hotword and an audio signal indicating that the computing device is to bypass further processing of the audio data; after determining that the audio data includes the predefined hotword and the audio signal indicating that the computing device is to bypass further processing of the audio data, continuing, by the computing device, to perform the operation; and in response to determining, by the computing device, that the audio data includes the predefined hotword and the audio signal indicating that the computing device is to bypass further processing of the audio data, bypassing, by the computing device, further processing of the audio data. - View Dependent Claims (16, 17)
