Jun 10, 2010 · The algorithm is based on finding the minimum statistics of noisy speech for each subband over a time window. Its major drawback is that when ...
A new method of parametric spectral estimation, which is called minimum-free-energy (MFE) estimation, is introduced. The MFE method produces a generic theoretic ...
The subband noise estimate is updated by adaptively smoothing the noisy signal power. The smoothing parameter is chosen as a function of the estimated ...
