ABSTRACT
BACKGROUND AND

OBJECTIVES:

The purpose of this study was to investigate the criterion-related concurrent validity of two standardized auditory-perceptual assessments and the Acoustic Voice Quality Index (AVQI) for measuring dysphonia severity in patients with vocal cord paralysis (VCP). MATERIALS AND

METHODS:

Total 210 patients with VCP and 236 normal voice subjects were asked to sustain the vowel [a] and to read aloud the Korean text “Walk”. A 2 second mid-vowel portion of the sustained vowel and two sentences (with 26 syllables) were recorded. And then voice samples were edited, concatenated, and analyzed according to Praat script. Two standardized auditory-perceptual assessment (GRBAS and CAPE-V) were performed by three raters.

RESULTS:

The VCP group showed higher AVQI, Grade (G) and Overall Severity (OS) values than normal voice group. And the correlation among AVQI, G, and OS ranged from 0.904 to 0.926. In ROC curve analysis, cutoff values of AVQI, G, and OS were < 3.79, < 0.00, and < 30.00, respectively, and the AUC of each analysis was over .89.

CONCLUSION:

AVQI and auditory evaluation can improve the early screening ability of VCP voice and help to establish effective diagnosis and treatment plan for VCP-related dysphonia.
