A computer-implemented method comprising: receiving, by a computing device (i) that is operating in a low-power mode and that includes a display that displays a graphical user interface while the computing device is in the low-power mode and (ii) that is configured to exit the low-power mode in response to detecting a first hotword, audio data corresponding to an utterance; and while the computing device remains in the low-power mode: determining, by the computing device, that the audio data includes a second, different hotword; in response to determining that the audio data includes the second, different hotword, obtaining, by the computing device, a transcription of the utterance by performing speech recognition on the audio data; based on the second, different hotword and the transcription of the utterance, generating, by the computing device, an additional graphical user interface; and providing, for output on the display, the additional graphical user interface, wherein: the low-power mode consumes less power than a high-power mode of the computing device, while in the low-power mode, the computing device does not perform at least one action that is performed by the computing device while in the high-power mode, and each of the first and second hotwords is a predetermined word that is spoken to invoke the attention of the computing device. receiving, by a computing device (i) that is operating in a low-power mode and that includes a display that displays a graphical user interface while the computing device is in the low-power mode and (ii) that is configured to exit the low-power mode in response to detecting a first hotword, audio data corresponding to an utterance; and while the computing device remains in the low-power mode: determining, by the computing device, that the audio data includes a second, different hotword; in response to determining that the audio data includes the second, different hotword, obtaining, by the computing device, a transcription of the utterance by performing speech recognition on the audio data; based on the second, different hotword and the transcription of the utterance, generating, by the computing device, an additional graphical user interface; and providing, for output on the display, the additional graphical user interface, determining, by the computing device, that the audio data includes a second, different hotword; in response to determining that the audio data includes the second, different hotword, obtaining, by the computing device, a transcription of the utterance by performing speech recognition on the audio data; based on the second, different hotword and the transcription of the utterance, generating, by the computing device, an additional graphical user interface; and providing, for output on the display, the additional graphical user interface, wherein: the low-power mode consumes less power than a high-power mode of the computing device, while in the low-power mode, the computing device does not perform at least one action that is performed by the computing device while in the high-power mode, and each of the first and second hotwords is a predetermined word that is spoken to invoke the attention of the computing device. the low-power mode consumes less power than a high-power mode of the computing device, while in the low-power mode, the computing device does not perform at least one action that is performed by the computing device while in the high-power mode, and each of the first and second hotwords is a predetermined word that is spoken to invoke the attention of the computing device. <EOS>
