This study aimed to investigate construct convergent validity of the Persian version of consensus auditory perceptual evaluation of voice (called ATSHA), using the acoustic measurements. Moreover, the effect of voice tasks on the perceptual ratings was studied. The study data were gathered from a total of 40 dysphonic patients (Mean±SD age=36.79±8.26 years). Perceptual voice evaluation was performed using the ATSHA during sustained vowels and sentence reading tasks. The acoustic features including fundamental frequency (F0), intensity, jitter, shimmer, and Harmonics-to-Noise Ratio (HNR) were extracted using Praat application. To assess construct validity of ATSHA, correlation between perceptual and acoustic measures were studied. The effect of tasks was investigated by mean comparison and Pearson correlation. The results demonstrate that ATSHA has significant correlation with all acoustic measures except the frequency (r=-0.08-0.35; P≥0.05). There was no significant correlation between pitch and the acoustic measures of intensity and jitter (r=-0.31; P=0.05 and r=0.24; P=0.14, respectively). The highest correlation observed between the overall severity and the HNR (r=-0.85; P<0.001). The correlation between the perceptual scores in both tasks was high (r=0.82-0.99, P<0.05). The ATSHA is a valid scale for perceptual judgment on intensity, jitter, shimmer, and HNR. However, this scale could not estimate the frequency of voice in dysphonia. The current study demonstrate that vowel prolongation and sentence reading has no noticeable effect on the perceptual ratings in dysphonia.

Auditory-perceptual assessment of voice a main approach in the diagnosis and therapy improvement of voice disorders. Despite, there are few Iranian studies about auditory-perceptual assessment of voice. The aim of present study was development and determination of validity and rater reliability of Persian version of the Consensus Auditory Perceptual Evaluation of Voice (CAPE -V). The qualitative content validity was detected by collecting 10 questionnaires from 9 experienced speech and language pathologists and a linguist. For reliability purposes, the voice samples of 40 dysphonic (neurogenic, functional with and without laryngeal lesions) adults (20-45 years of age) and 10 normal healthy speakers were recorded. The samples included sustain of vowels and reading the 6 sentences of Persian version of the consensus auditory perceptual evaluation of voice called the ATSHA. The qualitative content validity was proved for developed Persian version of the consensus auditory perceptual evaluation of voice. Cronbach’s alpha was high (0.95). Intra-rater reliability coefficients ranged from 0.86 for overall severity to 0.42 for pitch; inter-rater reliability ranged from 0.85 for overall severity to 0.32 for pitch (p<0.05). The ATSHA can be used as a valid and reliable Persian scale for auditory perceptual assessment of voice in adults.
