  • Patent number: 11876905
    Abstract: A trust token may be created including authentication data for a user and his or her associated communication device. The trust token may be transmitted by the communication device to one or more recipients, such as a token server. The recipients may interpret the trust token and verify it against data written to one or more nodes of a blockchain when the user and the communication device registered for the trust token. Once the trust token is verified, the token server may be configured to generate, maintain, and provision account tokens representing sensitive data. The token server may push one or multiple account tokens to the communication device, thereby allowing the communication device to perform transactions with the account tokens. In other words, the implementation of a trust token may allow the communication device to be provisioned with multiple account tokens, without requiring multiple logins or transmissions of sensitive data.

  • Patent number: 11776563
    Abstract: A method includes receiving an overlapped audio signal that includes audio spoken by a speaker that overlaps a segment of synthesized playback audio. The method also includes encoding a sequence of characters that correspond to the synthesized playback audio into a text embedding representation. For each character in the sequence of characters, the method also includes generating a respective cancelation probability using the text embedding representation. The cancelation probability indicates a likelihood that the corresponding character is associated with the segment of the synthesized playback audio overlapped by the audio spoken by the speaker in the overlapped audio signal.

  • Publication number: 20230298609
    Abstract: A method for training a generalized automatic speech recognition model for joint acoustic echo cancellation, speech enhancement, and voice separation includes receiving a plurality of training utterances paired with corresponding training contextual signals. The training contextual signals include a training contextual noise signal including noise prior to the corresponding training utterance, a training reference audio signal, and a training speaker vector including voice characteristics of a target speaker that spoke the corresponding training utterance. The operations also include training, using a contextual signal dropout strategy, a contextual frontend processing model on the training utterances to learn how to predict enhanced speech features. Here, the contextual signal dropout strategy uses a predetermined probability to drop out each of the training contextual signals during training of the contextual frontend processing model.
