A computer-implemented method, comprising: identifying, by a first computing device that is configured to respond to a particular, predefined hotword, a second computing device that is configured to respond to the particular, predefined hotword; receiving, by the first computing device and by the second computing device, audio data for an utterance spoken by a user; determining, by the first computing device and by the second computing device, that the utterance includes the particular, predefined hotword; determining, by the first computing device and by the second computing device, that the second computing device will output an initial response to the utterance; receiving, by the first computing device, a transcription of the initial response to the utterance, wherein the transcription of the initial response is provided by the second computing device; based on the transcription of the initial response and based on the utterance, generating, by the first computing device, a subsequent response to the initial response, wherein generating the subsequent response to the initial response comprises: determining user information that is associated with a first user of the first computing device or with a second user of the second computing device and/or accessing data that is associated with the initial response and/or determining, by the first computing device, a location of the first computing device; and wherein generating the subsequent response to the initial response is based on the user information and/or the accessed data and/or the location of the first computing device such that the subsequent response augments the initial response and provides additional information; and providing, for output by the first computing device, audio data for the subsequent response or a transcription of the subsequent response. identifying, by a first computing device that is configured to respond to a particular, predefined hotword, a second computing device that is configured to respond to the particular, predefined hotword; receiving, by the first computing device and by the second computing device, audio data for an utterance spoken by a user; determining, by the first computing device and by the second computing device, that the utterance includes the particular, predefined hotword; determining, by the first computing device and by the second computing device, that the second computing device will output an initial response to the utterance; receiving, by the first computing device, a transcription of the initial response to the utterance, wherein the transcription of the initial response is provided by the second computing device; based on the transcription of the initial response and based on the utterance, generating, by the first computing device, a subsequent response to the initial response, wherein generating the subsequent response to the initial response comprises: determining user information that is associated with a first user of the first computing device or with a second user of the second computing device and/or accessing data that is associated with the initial response and/or determining, by the first computing device, a location of the first computing device; and wherein generating the subsequent response to the initial response is based on the user information and/or the accessed data and/or the location of the first computing device such that the subsequent response augments the initial response and provides additional information; and determining user information that is associated with a first user of the first computing device or with a second user of the second computing device and/or accessing data that is associated with the initial response and/or determining, by the first computing device, a location of the first computing device; and wherein generating the subsequent response to the initial response is based on the user information and/or the accessed data and/or the location of the first computing device such that the subsequent response augments the initial response and provides additional information; and providing, for output by the first computing device, audio data for the subsequent response or a transcription of the subsequent response.
