A study of selected acoustic parameters of voice in typically developing children

A voice disorder can bring about deep implications to social life, both in children and in adults. Voice disorders in children

are relatively frequent, affecting 6 to 23% of the children population (Nicollas, Triglia 2008).The etiological factors associated

with childhood dysphonia require early and precise assessments. In order for these assessments to be reliable it is necessary to

establish well defined normality standards among the genders and different age ranges. This study aims to assess acoustic voice

parameters of normally developing male and female children aged between 4 and 12 years in order to provide a representative

normative database. The range of etiological factors associated with child dysphonia requires precise diagnosis. Because of the

differences in anatomy between adults and children, normative data for the adult population should not be used as evaluative

standards for the pediatric population (Sapienza, Ruddy and Baker, 2004). Participants will be instructed to make a deep

inhalation before sustaining the phonation of the vowel and then will be instructed to sustain phonation of /a/, /i/, /u/ for 5

seconds, keeping a constant pitch and at a loudness level which would be comfortable for him/her. Two trials will be taken

and phonation on the second trial will be recorded using Sony digital recorder. The wave files will be transferred to Visipitch-

IV as per the instructions in the manual. Thus preventing recording characteristics which influence acoustic parameters. The

aforementioned acoustic parameters will be analysed. Results will be discussed in terms of gender and age differences.
