Summary
This study established the first pediatric normative voice database using the Multi-Dimensional Voice Program (MDVP). Children with vocal fold nodules showed elevated frequency perturbation, indicating potential for diagnosing voice disorders.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Acoustic Analysis
Background:
- The Multi-Dimensional Voice Program (MDVP) is a computerized system for voice analysis.
- Establishing normative pediatric voice data is crucial for accurate diagnosis and treatment.
- Previous research has not comprehensively characterized pediatric voice profiles using MDVP.
Purpose of the Study:
- To create the first normative pediatric database for the Multi-Dimensional Voice Program (MDVP).
- To characterize the vocal profiles of children aged 4-18 years.
- To compare normative data with the vocal profiles of pediatric patients diagnosed with vocal fold nodules.
Main Methods:
- A cross-sectional, observational design was employed to build the normative database.
- A case-control design was used for the comparative study.
- One hundred healthy children (50 boys, 50 girls) and 26 children with vocal fold nodules participated.
Main Results:
- Acoustic variables were extracted using the MDVP, yielding up to 33 measures per voice sample.
- Boys aged 12 exhibited a significant decrease in fundamental frequency.
- Patients with vocal fold nodules displayed significantly elevated frequency perturbation compared to controls (P<.001).
Conclusions:
- Pediatric vocal profiles are consistent across girls and prepubescent boys.
- Vocal fold nodules are associated with a distinct acoustic profile marked by increased frequency perturbation.
- Normative acoustic ranges can aid in detecting vocal fold abnormalities and monitoring voice therapy outcomes.
