The phonatory signature of the vocal pathology is a subject concerning the teams working on the voice abnormality, mainly for diagnostic and rehabilitation purposes. Classically, it is assumed that the pathology changes the fundamental frequency of the voice and does not modify the formants. The present study was made on a group of profoundly deaf children. Altogether 60 children (20 patients and 40 people in a control group) were included in this study. Eleven oral vowels were taken in a spoken sentence. The authors tested the discriminating capacity of the fundamental frequency of the voice and the three first formants. The results show the parameters variability, the parameters modified by the pathology and some characteristics of the voice of the deaf child.
