Comparison of voice perceptual charactheristics between speech - language pathologists % dysphonic and normal voiced adultʹs view

Background and Aim: In recent years, several tools for assessment of quality of patient life have been designed especially for dysphonics. Nowadays, we have useful assessments in health system that are refered for numerous clinical decisions. In this way, this investigation compares clinician and patient perception in dysphonic and normal voiced for first time. Methods: This study was carried out on 30 dysphonic and 30 subjects with normal voice. Their age, sex and job were same. In two groups, Consensus Auditory - Perceptual Evaluation of Voice (CAPE- V) was used for evaluation of clinician perception and Voice Handicap Index - 30 (VHI-30) for assessment of patient perception. After collecting data, they were analyzed by Mann- witney and Wilcoxon tests. Results: The research revealed that mean of total and each section score of VHI-30 have significant difference between dysphonic and control group (p<0.01). Comparison of total and every parameter score of CAPE-V and speed also indicated significant difference between two groups (p<0.01). Study of reliability shows weak reliability (r=0.34) between clinician and patient perception of voice in dysphonics. Conclusion: Dysphonic patients percept their voice problem different and severe rather than clinicians that shows physical, psychological and social affects of dysphonia. This research confirms that patient - based assessment of voice is necessary to be part of common assessments of dysphonia.
