Speech enhancement with noise estimation in bark domain;

During the noise estimation,the estimation of its spectrum is updated by tracking the speech-absent frames.

After capturing theneighborhoods of discontinuity in the image and acquiring their spatial features based on noise estimation,adaptive optimal.

The method can track eigenvalue minima on each eigenvector without any distinction between the speech activity and the speech pause,thus updating the noise estimate throughout the entire signal.

When the statistics of noise are changing or signal-noise-ratio(SNR)is low,the noise estimated value by voice activity detection is not exact.
