Abstract
An improved noise suppression system (800) improves speech quality at the speech-over-noise signal available at the input (205) to generate a clear speech signal at the output (265) by modification of the spectral gain. The improvements of the present invention include the addition of a signal-to-noise ratio (SNR) threshold mechanism (830) to reduce hopping background noise by shifting the gain increase from the gain tables until a certain SNR threshold, the use of a speech metric calculator (810) to produce more precise estimates of background noise by means of update decisions based on global characteristics similar to speech in channels and interval of time since the last update, as well as the use of a channel SNR modifier (820) to develop immunity against narrowband noise pulses by modifying the calculation-based SNR estimates vocal metrics and channel energies.
