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.
