Contextual hotwords

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:
• determining, by a computing device, a context associated with the computing device;
• based on the context associated with the computing device, identifying, by the computing device, a hotword that, upon receipt by the computing device, initiates execution of an operation that is available for execution by a user;
• after identifying the hotword, receiving, by a microphone of the computing device, audio data that corresponds to an utterance;
• determining, by the computing device, that the audio data does not include the hotword by providing the audio data as an input to a hotword model;
• receiving, by the computing device and from a user, a non-audible request to perform the operation associated with the hotword;
• in response to receiving the non-audible request to perform the operation associated with the hotword, executing, by the computing device, the operation associated with the hotword and updating the hotword model;
• after updating the hotword model, receiving, by the microphone of the computing device, additional audio data that corresponds to an additional utterance;
• determining, by the computing device, that the additional audio data includes the hotword by providing the additional audio data as an input to the updated hotword model;
• and
• in response to determining that the additional audio data includes the hotword, executing, by the computing device, the operation associated with the hotword.

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:

• determining, by a computing device, a context associated with the computing device;
• based on the context associated with the computing device, identifying, by the computing device, a hotword that, upon receipt by the computing device, initiates execution of an operation that is available for execution by a user;
• after identifying the hotword, receiving, by a microphone of the computing device, audio data that corresponds to an utterance;
• determining, by the computing device, that the audio data does not include the hotword by providing the audio data as an input to a hotword model;
• receiving, by the computing device and from a user, a non-audible request to perform the operation associated with the hotword;
• in response to receiving the non-audible request to perform the operation associated with the hotword, executing, by the computing device, the operation associated with the hotword and updating the hotword model;
• after updating the hotword model, receiving, by the microphone of the computing device, additional audio data that corresponds to an additional utterance;
• determining, by the computing device, that the additional audio data includes the hotword by providing the additional audio data as an input to the updated hotword model;
• and
• in response to determining that the additional audio data includes the hotword, executing, by the computing device, the operation associated with the hotword.
