Summary
This study created the largest English-language pediatric voice database, revealing distinct vocal profiles and key developmental changes in children
Area of Science:
- Pediatric Otolaryngology
- Speech Science
- Voice Acoustics
Background:
- Establishing normative pediatric voice data is crucial for understanding vocal development.
- Existing databases often lack comprehensive acoustic analysis for diverse age groups.
Purpose of the Study:
- To create a normative pediatric acoustic database for children aged 4-18 years.
- To analyze acoustic characteristics and identify sex- and age-specific vocal changes.
Main Methods:
- Prospective collection of acoustic parameters from 335 healthy children (165 girls, 170 boys).
- Utilized computerized voice analysis in a pediatric otolaryngology clinic setting.
Main Results:
- Identified discrete fundamental frequency changes at specific ages in girls (11, 14) and boys (12, 16).
- Jitter, shimmer, and noise-to-harmonic ratio values were within adult normative thresholds.
- Established distinct vocal profiles for boys and girls, with significant differences in fundamental frequency.
Conclusions:
- This is the largest pediatric computerized voice analysis database in English.
- The database enables age- and sex-based growth charts for tracking pediatric voice maturation.
- Findings support future voice therapy, phonosurgical strategies, and research on pediatric voice development.
