This paper presents an objective singing quality evaluation approach based on a study of the relationship between acoustic measurements and perceptual ratings of singing voice quality. Individual perceptual criteria's contributions to the overall rating are also investigated to find significant evaluation terms. Experimental results show that critical perceptual criteria for singing evaluation have strong correlation with objective acoustic parameters, especially with combined acoustic features. And the proposed objective evaluation approach is tested to be comparable to human judges.
