Background Measurement of treatment outcomes is critical for the spectrum of voice
treatments (ie, surgical, behavioral, or pharmacological). Outcome measures typically …

Objectives The validity and sensitivity to change of instrumental acoustic measurements in
patients with functional dysphonia have been controversially discussed. This work examines …

Summary Objectives The Acoustic Voice Quality Index (AVQI) and the Cepstral Spectral
Index of Dysphonia (CSID) are two multiparameter acoustic indices designed to objectively …

Voice practitioners require an objective index of dysphonia severity as a means to reliably
track treatment outcomes. To ensure ecological validity however, such a measure should …

Purpose The purpose of this experiment was to assess the ability of an acoustic model
composed of both time-based and spectral-based measures to track change following voice …

Summary Background The original Dysphonia Severity Index (ie, DSI) weighs and combines
four voice markers in a single number to size dysphonia gradation in the clinic: percent jitter …

Measurement of dysphonia severity involves auditory-perceptual evaluations and acoustic
analyses of sound waves. Meta-analysis of proportional associations between these two …

Purpose Instrumental voice assessment plays a critical role in identifying vocal issues and
for documenting treatment outcomes. The reported voice data, however, are sensitive to the …

Introduction Over the past several decades, many acoustic parameters have been studied
as sensitive to and to measure dysphonia. However, current acoustic measures might not be …

OBJECTIVES: To examine the validity of the Cepstral Spectral Index of Dysphonia (CSID) as
an objective treatment outcomes measure of dysphonia severity. METHOD: Pre-and …
