Latest Patents

One of his latest patents is titled "Optimizing personal VAD for on-device speech recognition." This computer-implemented method involves receiving a sequence of acoustic frames corresponding to an utterance and generating a reference speaker embedding for the utterance. The method also includes receiving a target speaker embedding for a target speaker and generating feature-wise linear modulation (FiLM) parameters, which include a scaling vector and a shifting vector based on the target speaker embedding. Additionally, the method generates an affine transformation output that scales and shifts the reference speaker embedding based on the FiLM parameters. Ultimately, it produces a classification output indicating whether the utterance was spoken by the target speaker based on the affine transformation output.

Another significant patent is "Voice shortcut detection with speaker verification." This patent focuses on streaming keyphrase detection that can be customized to detect specific keyphrases without requiring retraining of any models. The implementation includes processing audio data using a speaker separation model to generate separated audio data, isolating an utterance spoken by a human speaker from other sounds. The separated audio data is then processed using a text-independent speaker identification model to determine if a verified user spoke the utterance. The system can perform actions corresponding to the detected keyphrase when the conditions are met.
