  • Earbud speech estimation
    Patent number: 11134330
    Abstract: Embodiments of the invention determine a speech estimate using a bone conduction sensor or accelerometer, without employing voice activity detection gating of speech estimation. Speech estimation is based either exclusively on the bone conduction signal, or is performed in combination with a microphone signal. The speech estimate is then used to condition an output signal of the microphone. There are multiple use cases for speech processing in audio devices.
    Type: Grant
    Filed: July 12, 2019
    Date of Patent: September 28, 2021
    Assignee: Cirrus Logic, Inc.
    Inventors: David Leigh Watts, Brenton Robert Steele, Thomas Ivan Harvey, Vitaliy Sapozhnykov
