Abstract :
Vocal quality was quantified in 64 normal subjects and 57 glottal cancer patients in terms of various averages of four measures of short-term signal stability. The combined and individual measures were evaluated by comparison with values of two perceptual qualities. The results show that the combined measures perform slightly better than the individual parameters
