Method for objectively estimating voice quality on the basis of perceptual parameters

The invention discloses a method for objectively estimating voice quality on the basis of perceptual parameters, particularly a method for objectively estimating the voice quality by using a human auditory model considering the change in both time and frequency. The human auditory model which is established according to the physiological, physical and neurophysiological phenomena can successfully describe the estimation and the analysis of the voice signal in two human auditory perception stages, three characteristic parameters which can probably affect the voice quality judgment by the hearer perceptually are captured in the two human auditory perception stages to objectively estimate the voice quality, wherein the three characteristic parameters are respectively the intelligibility, the clarity and the naturalness. The relationships among the three characteristic parameters and the voice quality which can be affected by the three characteristic parameters are combined through the complex regression analysis
