Abstract | Background
Currently, there is a lack of pediatric normative database on how Cantonese dysphonic children manifest differently
from vocally healthy Cantonese children in terms of vocal functions. Data reported in the literature on English-speaking
children cannot be directly applied to Cantonese-speaking children because Cantonese is a tone language and
English is a non-tone language. Voice measures can manifest differently between tone and non-tone languages.
Objective
The aim of the present study was to evaluate the dysphonic severity for Cantonese-speaking school-age children
using a multi-parametric approach.
Methods
Thirty dysphonic children with laryngeal pathologies and 30 controls with normal voices participated in the study.
All children were native Cantonese speakers and were aged from 6 to 12 years. Each child undertook several voice
recordings for perceptual, acoustic perturbation, voice range profile (phonetogram) and aerodynamic evaluation.
Results
The dysphonic group demonstrated significantly more severe voice quality (p<0.001) than the control group. The
dysphonic group also demonstrated significantly smaller voice range profile area (p<0.001), shorter maximum phonation
time (p<0.001), significantly higher level of jitter and shimmer values (both p<0.01) than the control group.
Conclusions
The study provides a preliminary database of vocal functions in Cantonese-speaking children.
