  • Patent number: 10964335
    Abstract: Methods, systems, and devices for auditory enhancement are described. A device may receive a respective auditory signal at each of a set of microphones, where each auditory signal includes a respective representation of a target auditory component and one or more noise artifacts. The device may identify a directionality associated with a source of the target auditory component (e.g., based on an arrangement of the multiple microphones). The device may determine a distribution function for the target auditory component based at least in part on the directionality associated with the source and on the received plurality of auditory signals. The device may generate an estimate of the target auditory component based at least in part on the distribution function and output the estimate of the target auditory component.

  • Patent number: 10798513
    Abstract: Methods, systems, and devices for head-related transfer function generation are described. A device may receive a digital representation of a first audio signal associated with a location relative to a subject, and select from a database a first reference head-related transfer function measurement pair corresponding to the location of the first audio signal. The device may then obtain a second head-related transfer function measurement pair by performing a style transfer operation on the selected reference head-related transfer function measurement pair based on a set of head-related transfer function measurement pairs specific to the subject. As a result, the device may output a second audio signal based on the digital representation of the first audio signal and the second head-related transfer function measurement pair.

  • Publication number: 20200286491
    Abstract: A device includes a processor configured to determine a feature vector based on an utterance and to determine a first embedding vector by processing the feature vector using a trained embedding network. The processor is configured to determine a first distance metric based on distances between the first embedding vector and each embedding vector of a speaker template. The processor is configured to determine, based on the first distance metric, that the utterance is verified to be from a particular user. The processor is configured to, based on a comparison of a first particular distance metric associated with the first embedding vector to a second distance metric associated with a first test embedding vector of the speaker template, generate an updated speaker template by adding the first embedding vector as a second test embedding vector and removing the first test embedding vector from test embedding vectors of the speaker template.

  • Patent number: 10720165
    Abstract: A method of authenticating a user based on voice recognition of a keyword includes generating, at a processor, clean speech statistics. The clean speech statistics are generated from an audio recording of the keyword spoken by the user during an enrollment phase. The method further includes separating speech data and noise data from noisy input speech using the clean speech statistics during an authentication phase. The method also includes authenticating the user by comparing the speech data to the clean speech statistics or by comparing the noisy input speech to noisy speech statistics. The noisy speech statistics are based at least in part on the noise data.
