Pediatric voice analysis: comparison of 2 computerized analysis systems.

Importance: This research contributes to the pediatric objective voice measurement database while identifying comparable measurements between 2 available voice analysis systems.

Objective: To compare selective normative pediatric acoustic variables between the Multi-Dimensional Voice Program (MDVP) and the Voice Evaluation Suite (VES) computerized voice analysis systems. Additionally, it describes the first comprehensive pediatric database analyzing fundamental frequency, jitter, shimmer, and noise to harmonic ratio using the VES.

Establishment of a normative pediatric acoustic database.

OBJECTIVES To establish a normative pediatric acoustic database and to analyze the acoustic characteristics of the age groups studied. DESIGN Prospective gathering of acoustic parameters on healthy children aged 4 to 18 years. SETTING An outpatient pediatric otolaryngology clinic.

Pediatric laryngeal diadochokinetic rates: establishing a normative database.

Objective: Laryngeal diadochokinetic (L-DDK) rate is a measure of laryngeal neural integrity. The objectives for this study included the following: (1) establish the first comprehensive pediatric normative database for L-DDK rates (DDK) using the Voice Evaluation Suite, a computerized voice analysis program; and (2) analyze normal L-DDK rates for age and gender differences.

Study Design: Cross-sectional study with planned data collection.
