|
The purpose of this study was to explore the criterion-related concurrent validity of two standardized auditory-perceptual assessments and the Acoustic Voice Quality Index (AVQI) for measuring dysphonia severity in aging voice population. Materials and Methods：292 subjects with aging voice and 121 normal voice subjects were asked to sustain the vowel [a:] and to read aloud the Korean text ‘‘Walk’’. A 2second mid-vowel portion of the sustained vowel and two sentences (with 26 syllables) were edited, concatenated, and analyzed according to Praat script. And then auditory-perceptual assessment was performed by three raters. Results：The aging voice group showed higher AVQI, G and OS values than normal voice group. And the correlation among AVQI, G, and OS ranged from 0.827 to 0.902. In ROC curve analysis, cutoff values of AVQI, G, and OS were ＜4.22, ＜0.00, and ＜30.00, respectively, and the AUC of each analysis was over .90. Conclusions：AVQI and auditory evaluation can improve the early screening ability of aging voice and help to establish effective diagnosis and treatment plan for age-related dysphonia.
