Speech Enhancement from the Fullband Output SNR Perspective

Chapter
Part of the SpringerBriefs in Electrical and Computer Engineering book series (BRIEFSELECTRIC)

Abstract

Most of the speech enhancement algorithms are implemented in the timefrequency domain, i.e., the short-time Fourier transform (STFT) domain. The two main advantages of the STFT are that the algorithms can be implemented very efficiently and the different frequency bins can apparently be manipulated in a very flexible way in order to better compromise between noise reduction and speech distortion. Therefore, it is important to understand how things work from the fullband output SNR perspective and how gains/filters for noise reduction can be improved by fully exploiting all facets of this fundamental measure.
