Abstract
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.

Abstract
Background and Aim: Vocal abuse and misuse are the most frequent causes of voice disorders. Consequently some therapy is needed to stop or modify such behaviors. This research was performed to study the effectiveness of vocal hygiene program on perceptual signs of voice in people with dysphonia. Methods: A Vocal hygiene program was performed to 8 adults with dysphonia for 6 weeks. At first, Consensus Auditory- Perceptual Evaluation of Voice was used to assess perceptual signs. Then the program was delivered, Individuals were followed in second and forth weeks visits. In the last session, perceptual assessment was performed and individuals&apos opinions were collected. Perceptual findings were compared before and after the therapy. Results: After the program, mean score of perceptual assessment decreased. Mean score of every perceptual sign revealed significant difference before and after the therapy (p≤0.0001). «Loudness» had maximum score and coordination between speech and respiration indicated minimum score. All participants confirmed efficiency of the therapy. Conclusion: The vocal hygiene program improves all perceptual signs of voice although not equally. This deduction is confirmed by both clinician-based and patient-based assessments. As a result, vocal hygiene program is necessary for a comprehensive voice therapy but is not solely effective to resolve all voice problems.

Abstract
Background and Aim: An imbalance between phonatory subsystems may lead to disturbing phonatory muscular balance and consequently voice disorders. Based on theoretical issues, criterion-based laryngeal manual therapy, as a novel treatment method which is supported by classical laryngeal manual therapy, can improve voice quality using manual maneuvers combined with phonatory tasks. The present study aimed to report the treating effects of this method on hyperfunctional voice disorders. Methods: Twenty adult participants with hyperfunctional voice disorders by the least three months history of voice disorder were selected. The participant’s voices were assessed multidimensionally using acoustic, audio-pecreptual and stroboscopic assessments before and after treatment. Results: There were a decrease in jitter (p=0.003) and shimmer (p<0.001) and also, increase in harmonic-to-noise ratio (HNR) (p<0.001) of vowel /a/ after treatment. Besides, there was an increase in harmony to noise ratio (p=0.009) and decrease in jitter (p=0.020) of vowel /i/, too. There were not significant changes in shimmer amount of vowel /i/ (p=0.170) after treatment. There were highly significant changes in all aspects of audio-perceptual (p<0.001) and videostroboscopic (p<0.001) parameters. Conclusion: Using voice-based laryngeal manual therapy can be a treatment method in handling hyperfunctional voice disorders.
