In this paper voice quality of normal speech is qualitatively classified by five components of breathy, creaky, rough, nasal,and thin/thick voice. To determine whether a correlation exists between a subjective measure of voice and an objectivemeasure of voice, each voice is perceptually evaluated using the 1/2/3 scale by speech processing specialists and acousticallyanalyzed using speech analysis tools such as the Praat, MDVP, and VoiceSauce. The speech parameters include featuresrelated to speech source and vocal tract filter. Statistical analysis uses a two-independent-samples non-parametric test. Experimental results show that statistical analysis identified a significant correlation between the speech feature parametersand the components of voice quality.
