Objective quality evaluation of speech band-limited signals
Наталия Владимировна Богданова, Arkadiy Prodeus · Electronics and Communications · 2014
Dependence of objective quality evaluation of speech band-limited signals is experimentally obtained. As part of this task, a comparison of the considered indicators of the speech quality had been made. It is shown that computationally simple indicators, such as segmental SNR (SSNR) and log-spectral distortion (LSD), may not adequately respond to changes in bandwidth. More complex computationally perceptual indicators, such as bark spectral distortion (BSD) and perceptual evaluation of speech quality (PESQ), behave much more correct and, in the end, clarify the real needs of the human auditory system to speech perception.Reference 14, figures 5.
