Abstract :
The perceptual spectrum distortion (PSD), based on the auditory properties of a human being, is presented as a speech distortion measure. The PSD measure calculates the speech distortion distance by simulating the auditory properties of a human being and converting the short-time speech power spectrum to the auditory perceptual spectrum. Preliminary simulative experiments in comparison with Itakura´s measure have been done. The results of experiments show that the PSD measure is a preferable speech distortion measure which is consistent with a subjective assessment of speech quality.
