Hotword detection on multiple devices
First Claim
1. A computer-implemented method comprising:
- receiving, by a first computing device that is configured to respond to a particular, predefined hotword and from a second computing device that is in a vicinity of the first computing device, data indicating that the second computing device is configured to respond to the particular, predefined hotword;
transmitting, to the second computing device and by the first computing device, data indicating that the first computing device is configured to respond to the particular, predefined hotword;
determining a group identifier that identifies the first computing device and the second computing device;
receiving, by the first computing device, audio data that corresponds to an utterance;
determining that the utterance likely includes the particular, predefined hotword;
in response to determining that the utterance likely includes the particular, predefined hotword, transmitting, to a server, (i) data indicating that the first computing device likely received the particular, predefined hotword, (ii) data identifying the first computing device, and (iii) the group identifier that identifies the first computing device and the second computing device;
receiving, from the server, an instruction to commence speech recognition processing on the audio data; and
in response to receiving the instruction to commence speech recognition processing on the audio data, processing at least a portion of the audio data using an automated speech recognizer on the first computing device.

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 audio data that corresponds to an utterance. The actions further include determining that the utterance likely includes a particular, predefined hotword. The actions further include transmitting (i) data indicating that the computing device likely received the particular, predefined hotword, (ii) data identifying the computing device, and (iii) data identifying a group of nearby computing devices that includes the computing device. The actions further include receiving an instruction to commence speech recognition processing on the audio data. The actions further include in response to receiving the instruction to commence speech recognition processing on the audio data, processing at least a portion of the audio data using an automated speech recognizer on the computing device.

10. A computer-implemented method comprising:
-
receiving, by a server and from a first computing device, data indicating that the first computing device is configured to respond to a particular, predefined hotword; receiving, by the server and from a second computing device that is in a vicinity of the first computing device, data indicating that the second computing device is configured to respond to the particular, predefined hotword; determining a group identifier that identifies the first computing device and the second computing device; receiving, by a server and from the first device, (i) data indicating that the first computing device likely received the particular, predefined hotword, (ii) data identifying the first computing device, and (iii) the group identifier that identifies the first computing device and the second computing device; accessing context data that indicates a context of the first computing device; based on the context data of the first computing device, determining that the first computing device commence speech recognition processing on audio data associated with the particular, predefined hotword; and transmitting, to the first computing device, an instruction to commence speech recognition processing on the audio data associated with the particular, predefined hotword. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
