Systems, methods, apparatus, and computer program products for speech signal processing using spectral contrast enhancement

摘要

Systems, methods, and apparatus for spectral contrast enhancement of speech signals, based on information from a noise reference that is derived by a spatially selective processing filter from a multichannel sensed audio signal, are disclosed.

主权项

1. A method comprising performing each of the following acts within a device that is configured to process audio signals:
performing a spatially selective processing operation within a spatially selective processing filter on a multichannel sensed audio signal to produce a source signal and a noise reference; and performing a first spectral contrast enhancement operation within a first spectral contrast enhancer on a far end speech signal and the noise reference to produce a first processed speech signal.
