Abstract
The maximum duration times for /s/ and /z/ and the calculated s/z ratio were obtained from 123 dysphonic children, 69 with vocal cord nodules and 54 with no vocal cord pathology. Significant differences were found in the duration of /s/ versus /z/. The s/z ratio was found not to be significantly different for the two groups. The results indicate that the s/z ratio does not discriminate the presence of mass lesions in dysphonic children.
