[0021] Transient Noise Suppression Method Based on Optimal Modified Log Spectral Amplitude Estimation (OM-LSA)
[0022] In order to realize speech noise suppression under low signal-to-noise ratio and non-stationary background noise, Cohen et al. proposed a transient noise suppression method based on Optimal Modified Log Spectral Amplitude Estimation (OM-LSA). This method has good robustness in low signal-to-noise ratio and non-stationary noise environment. The idea is to obtain the optimal spectral gain function of the observed signal through the prior signal-to-noise ratio estimation, noise estimation, and speech existence probability estimation of the observed signal, and finally multiply the frequency-domain observed signal with the gain function to obtain the denoised speech Signal. The functional block diagram based on the optimal modified log spectrum amplitude est...
