  • Pitch model for noise estimation
    Patent number: 8180636
    Abstract: Pitch is tracked for individual samples, which are taken much more frequently than an analysis frame. Speech is identified based on the tracked pitch and the speech components of the signal are removed with a time-varying filter, leaving only an estimate of a time-varying speech signal. This estimate is then used to generate a time-varying noise model which, in turn, can be used to enhance speech related systems.
    Type: Grant
    Filed: March 7, 2011
    Date of Patent: May 15, 2012
    Assignee: Microsoft Corporation
    Inventors: James G. Droppo, Alejandro Acero, Luis Buera
