    Abstract: A method includes determining, based at least in part on a type of information to be displayed at a display device associated with a computing device, a privacy level for the information to be displayed; and determining whether the privacy level satisfies a threshold privacy level. The method also includes, responsive to determining that the privacy level satisfies the threshold privacy level, determining whether an individual not associated with a currently active user account of the computing device is proximate to the display device. The method also includes determining an estimated speed of the individual not associated with the currently active user account relative to the display device. The method further includes determining, whether the estimated speed satisfies a threshold speed, and responsive to determining that the estimated speed satisfies the threshold speed, outputting the information such that at least a first portion of the information is obscured.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving audio data corresponding to an utterance, determining that the audio data corresponds to a hotword, generating a hotword audio fingerprint of the audio data that is determined to correspond to the hotword, comparing the hotword audio fingerprint to one or more stored audio fingerprints of audio data that was previously determined to correspond to the hotword, detecting whether the hotword audio fingerprint matches a stored audio fingerprint of audio data that was previously determined to correspond to the hotword based on whether the comparison indicates a similarity between the hotword audio fingerprint and one of the one or more stored audio fingerprints that satisfies a predetermined threshold, and in response to detecting that the hotword audio fingerprint matches a stored audio fingerprint, disabling access to a computing device into which the utterance was spoken.

    Abstract: A method includes receiving, from an audio streaming system, a probe audio sample and identifying sufficiently matching reference audio samples based on a first comparison of a first portion of the probe audio sample to reference audio samples. The method also includes, in response to determining that the sufficiently matching reference audio samples do not meet a predetermined score threshold, retaining the sufficiently matching reference audio samples, identifying additional matching reference audio samples based on a second comparison a second portion of the probe audio sample to the reference audio samples, and outputting at least one of the reference audio samples based on the first comparison and the second comparison.

    Abstract: In some implementations, a language proficiency of a user of a client device is determined by one or more computers. The one or more computers then determines a text segment for output by a text-to-speech module based on the determined language proficiency of the user. After determining the text segment for output, the one or more computers generates audio data including a synthesized utterance of the text segment. The audio data including the synthesized utterance of the text segment is then provided to the client device for output.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for verifying an identity of a user. The methods, systems, and apparatus include actions of receiving a request for a verification phrase for verifying an identity of a user. Additional actions include, in response to receiving the request for the verification phrase for verifying the identity of the user, identifying subwords to be included in the verification phrase and in response to identifying the subwords to be included in the verification phrase, obtaining a candidate phrase that includes at least some of the identified subwords as the verification phrase. Further actions include providing the verification phrase as a response to the request for the verification phrase for verifying the identity of the user.

    Abstract: Systems and methods for editing an MP4 multimedia container without transcoding are disclosed herein. Editing operations can be accomplished by transforming data included in the multimedia container rather than by transforming raw data streams and then reconverting to MP4 (or another) file format. In response to a target range that identifies a portion of the media content to maintain, a corresponding sample range in terms of the MP4 format can be constructed and data outside that range can be discarded, e.g., from the mdat atom and the sample tables atom(s).
