    摘要： A method system for use of Doppler shift as a basis to detect user focus, such as to detect that a user was attracted to audio media and/or to an associated object. A portable processing device carried by the user receives audio media emitted from an audio source at a fixed location, the audio media having periodic watermarking encoded at a baseline frequency. The portable processing device detects a change in frequency of the periodic watermarking over time, such as the frequency progressing from at least being higher than the baseline frequency to being the baseline frequency for at least a predefined threshold period of time. Based on the detected change in frequency of the periodic watermarking over time, the portable device then provides a report indicating that the user was attracted to the audio media and/or to an object (e.g., a commercial object) collocated with the audio source.

    摘要： Disclosed example people monitoring methods include detecting a first watermark in a first audio signal obtained from an acoustic sensor, the first watermark identifying media presented by a monitored media device, determining whether a second watermark, different from the first watermark, is embedded in the first audio signal obtained from the acoustic sensor, the second watermark identifying at least one of a mobile device or a user of the mobile device, classifying the second watermark as a media watermark or a people monitoring watermark based on a characteristic of the second watermark, and when the second watermark is determined to be embedded in the first audio signal, reporting at least one of the second watermark or information decoded from the second watermark to identify at least one of the mobile device or the user of the mobile device as being exposed to the media presented by the monitored media device.

    摘要： Display badges employing scene embedded digital watermarks for authenticating media data typically comprising: an audio detection component detecting at least a portion of ambient audio data of an actual event; a computing device operably connected to a recording component; the computing device converting at least a portion of the detected ambient audio data into a digital representation of the at least a portion of the ambient audio data; a display presenting a succession of images comprising the digital representation; where the display badges are designed such that the digital representation is sufficiently visible that it may be extracted by a computer upon replay of audio and video of some or all of the actual event, and the replay audio may be verified as authentic by comparing the digital representation with the audio associated with the replay. Methods for encoding and authenticating media data are also disclosed.

    摘要： Approaches presented herein provide for insertion of watermarks into synthesized content, such as audio content that may include synthesized speech to appear to be spoken by a digital avatar in a 3D virtual environment. A Text-to-Speech (TTS) generator, such as a trained neural network, can be used to produce synthetic speech audio, which can have an audio watermark inserted therein. This watermark can be detected by a process of a collaborative content generation platform, for example, and an indication can be provided that the content contains synthesized speech. The presence of the audio watermark will generally not be detectable by the human ear during presentation. To make it difficult to remove or modify the watermark, the watermark can be generated using a key or other unique piece of data known only to authorized entities.

    摘要： An audio file associated with a user voice query may be received at a user device. The audio file may be compared to a plurality of references, such as cache entries, corresponding to a plurality of other voice queries. Based on a determination that the voice query corresponds to one of the references, an operation associated with the voice query may be executed. An indication may be received that the operation was not an intended operation associated with the voice query. Based on receiving this indication, the incorrectly identified operation, associated reference, e.g., voice query, may be disabled for the user or the device. However, the cache entry may remain enabled for one or more of a plurality of other devices.

    摘要： A method operable in a receiver comprises the steps of: receiving an audio signal from a broadcaster; obtaining digital information comprising an identifier associated with the broadcaster; retrieving an audio watermark associated with the identifier; encoding the audio watermark in the audio signal; and outputting an acoustic signal based on the encoded audio signal so that the audio watermark can be sensed by a listening device without being audible by a human listener.
