Vocal Shimmer in Sustained Phonation Vocal shimmer during the sustained phonation of/a/, /i/, /u/ was investigated for thirty-one adult male speakers using an automatic analysis program. The results showed an overall average shimmer of 0.39 dB with a critical value of 0.98 dB. Significant correlations were found among shimmer, jitter and fo standard deviation. ... Research Article
