Hotword recognition and passive assistance

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 (i) that is operating in a low-power mode and that includes a display that displays a graphical 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;
• 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 user interface;
• and
• while the computing device remains in the low-power mode, providing, for output on the display, the additional graphical interface.

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 (i) that is operating in a low-power mode and that includes a display that displays a graphical 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;
• 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 user interface;
• and
• while the computing device remains in the low-power mode, providing, for output on the display, the additional graphical interface.
