Acoustic Analyses of Prolonged Vowels in Young Adults With Friedreich Ataxia.

Objectives: Finding measures that track disease progression and determine treatment efficacy is vital for appropriate management in Friedreich ataxia (FA). The purpose of this study was to determine which cepstral- and spectral-based measures extracted from prolonged vowels using Analysis of Dysphonia in Speech and Voice (ADSV) program discriminate between those who have FA and normal voice (NV) peers.

Study Design: This is a descriptive, prospective study.
