A computer-implemented method comprising: receiving audio data corresponding to an utterance that is received while a computing device is in a locked mode, the computing device being configured to exit the lock mode based on determining that the audio data corresponds to a hotword of a hotword recognition process that uses the hotword to unlock the computing device; determining whether the audio data corresponds to an utterance of the hotword; in response to determining that the audio data corresponds to an utterance of the hotword of the hotword recognition process that uses the hotword to unlock the computing device, generating a hotword audio fingerprint of the audio data that is determined to correspond to the utterance of the hotword of the hotword recognition process that uses the hotword to unlock the computing device; determining a similarity between the hotword audio fingerprint and one or more stored audio fingerprints of audio data that was previously determined to correspond to an utterance of the hotword of the hotword recognition process that uses the hotword to unlock the computing device; detecting whether the hotword audio fingerprint matches a stored audio fingerprint of audio data that was previously determined to correspond to an utterance the hotword of the hotword recognition process that uses the hotword to unlock the computing device based on whether the similarity between the hotword audio fingerprint and one of the one or more stored audio fingerprints satisfies a predetermined threshold; and in response to detecting that the hotword audio fingerprint matches a stored audio fingerprint, disabling access to the computing device into which the utterance was spoken by preventing the computing device from exiting the lock mode despite determining that the audio data corresponds to the utterance of the hotword of the hotword recognition process that uses the hotword to unlock the computing device; and the method comprising: receiving additional audio data corresponding to a voice command or query; and determining a type of the voice command or query, wherein the predetermined threshold is adjusted based on the type of the voice command or query, wherein the type of the query is representative of a context that is indicative of a sensitivity of the voice command or query. receiving audio data corresponding to an utterance that is received while a computing device is in a locked mode, the computing device being configured to exit the lock mode based on determining that the audio data corresponds to a hotword of a hotword recognition process that uses the hotword to unlock the computing device; determining whether the audio data corresponds to an utterance of the hotword; in response to determining that the audio data corresponds to an utterance of the hotword of the hotword recognition process that uses the hotword to unlock the computing device, generating a hotword audio fingerprint of the audio data that is determined to correspond to the utterance of the hotword of the hotword recognition process that uses the hotword to unlock the computing device; determining a similarity between the hotword audio fingerprint and one or more stored audio fingerprints of audio data that was previously determined to correspond to an utterance of the hotword of the hotword recognition process that uses the hotword to unlock the computing device; detecting whether the hotword audio fingerprint matches a stored audio fingerprint of audio data that was previously determined to correspond to an utterance the hotword of the hotword recognition process that uses the hotword to unlock the computing device based on whether the similarity between the hotword audio fingerprint and one of the one or more stored audio fingerprints satisfies a predetermined threshold; and in response to detecting that the hotword audio fingerprint matches a stored audio fingerprint, disabling access to the computing device into which the utterance was spoken by preventing the computing device from exiting the lock mode despite determining that the audio data corresponds to the utterance of the hotword of the hotword recognition process that uses the hotword to unlock the computing device; and the method comprising: receiving additional audio data corresponding to a voice command or query; and determining a type of the voice command or query, wherein the predetermined threshold is adjusted based on the type of the voice command or query, wherein the type of the query is representative of a context that is indicative of a sensitivity of the voice command or query. receiving additional audio data corresponding to a voice command or query; and determining a type of the voice command or query, wherein the predetermined threshold is adjusted based on the type of the voice command or query, wherein the type of the query is representative of a context that is indicative of a sensitivity of the voice command or query.
