System and method for adaptive intelligent noise suppression

摘要

Systems and methods for adaptive intelligent noise suppression are provided. In exemplary embodiments, a primary acoustic signal is received. A speech distortion estimate is then determined based on the primary acoustic signal. The speech distortion estimate is used to derive control signals which adjust an enhancement filter. The enhancement filter is used to generate a plurality of gain masks, which may be applied to the primary acoustic signal to generate a noise suppressed signal.

主权项

1. A method for adaptively controlling a noise suppressor, comprising:
receiving an acoustic signal; determining, using at least one hardware processor, a speech loss distortion estimate based on the acoustic signal, the speech loss distortion estimate being an estimate of potential degradation of speech introduced by the noise suppressor and being a function of a signal-to-noise ratio estimate of the acoustic signal; and controlling the noise suppressor based on the speech loss distortion estimate.
