An Improved MMSE Amplitude Estimator under Generalized Gamma Distribution Based on Auditory Perception
This paper describes a new speech enhancement approach which employs the minimum mean square error (MMSE) estimator based on the generalized gamma distribution of the short-time spectral amplitude (STSA) of a speech signal. In the proposed approach, the human perceptual auditory masking effect is in...
