ABSTRACT
OBJECTIVE: Describe and correlate the auditory-perceptual characteristics of the voice of nondysphonic school children from private and public schools from 8:0 to 10:0 years old, female and male. METHODS: Cross-sectional, quantitative and retrospective study of students from schools in a small city. Auditory-perceptual evaluations of 154 nondysphonic students were analyzed. Where considered nondysphonic those presenting overall severity bellow 34 mm using Consensus Auditory-Perceptual Evaluation of Voice. RESULTS: There was significantly higher strain in girls; significant positive correlation between age and the parameters overall severity, breathiness, and strain; significant differences in the mean values of the vocal parameters, with more evident roughness and breathiness in girls and breathiness in boys; in children from 8:0 to 9:0 years, all parameters were positively correlated; in children from 9:1 to 10:0 years, all vocal parameters except roughness increased and positive correlations became stronger. CONCLUSIONS: The strain was higher in girls; roughness, and breathiness were higher in girls, and breathiness was higher in boys. As age increased, all vocal parameters except roughness increased, and positive correlations became stronger.
