The purpose of this study was to compare professional (Pro) and non-professional (Non-pro) voice users with voice disorders in self-reporting voice evaluation using Korean-Voice Handicap Index (K-VHI) and Korean-Voice Related Quality of Life (K-VRQOL). In addition, those were compared by voice quality and voice disorder type. 94 Pro and 106 Non-pro were asked to fill out the K-VHI and K-VRQOL, perceptually evaluated on GRBAS scales, and divided into three types of voice disorders (functional, organic and neurologic) by an experienced speech-language pathologist and an otolaryngologist. The results showed that the functional (F) and physical (P) scores of K-VHI in Pro group were significantly higher than those in Non-pro group. As the voice quality evaluated by G scale got worse, the scores of all aspects except emotional (E) of K-VHI and social-emotional (SE) of K-VRQOL were higher. All scores of K-VHI and K-VRQOL in neurologic voice disorders were significantly higher than those in functional and organic voice disorders. In conclusion, professional voice users are more sensitive to their functional and physical handicap resulted by their voice problems and that goes double for the patients with severe and neurologic voice disorders.

This paper investigates the relationship between acoustic characteristics and voice handicap index for 29 males with esophageal speakers. Acoustic characteristics were measured by using a sustained vowel /a/ three times. The stable vocalization for 2 seconds was analyzed by MDVP program. Specifically, relationships between four VHI scores (total, functional, physical, and emotional) and three acoustic characteristics (jitter, shimmer, and NHR) were investigated using the Pearson correlation coefficient. As results, we found no relationship between NHR and VHI scores. However, both jitter and shimmer had statistically significant correlations with all four VHI scores. This research will contribute to establishing a baseline related to speech characteristics in voice rehabilitation with esophageal speakers. Further research could be done to examine the overall quality of life survey, which is widely used as a subjective measure about voice for patients with esophageal speakers.

The purpose of this study was to examine the relationship between subjective and objective evaluation in speakers with voice disorders. Subjective evaluation indicates the self-reports of voice problems by dysphonic speakers. The relating protocol is the Voice Handicap Index (VHI) and the self-awareness index of voice problems (SAIVP-14). A total of 48 individuals with voice disorders replied to the questionnaire and participated in a voice assessment. Objective evaluations included the perceptual judgement of G grade in GRBAS, acoustic measurements (jitter, shimmer, NHR) by MDVP (CSL 4400), and aerodynamic measurements (MPT, MFR, psub) by PAS (Phonatory Aerodynamic System, KayPentax, USA). Pearson and Spearman correlations were used for the analysis. In the correlation with perceptual judgement (G grade) and VHI-Total, VHI-Physical, and SAIVP-14, there was a significant correlation, but the overall correlation was poor. NHR, jitter, and shimmer were significantly correlated with overall VHI and SAIVP-14. Specifically, the correlation with shimmer was stronger compared to the other measurements. In aerodynamic measures, MFR and MPT showed a significant correlation with VHI-Total, VHI-Emotional, and SAIVP-14, but their correlation was poor. The results of this study suggested that subjective evaluation of self voice problems is meaningfully correlated with objective evaluations, but more data in the multidimensional voice assessment should be collected and analyzed for the reliability and validity of the voice handicap questionnaire.

주관적 음성평가는 음향분석기기를 이용한 객관적 음성 평가와 함께 음성분석에 유용하고 의미있는 평가방법이며 현재 알려진 검시법정 중에서 GRBAS 음성평가, VHI, patient self-perceptual voice rating이 가장 널리 사용되고 있고 인정받는 방법이다. 주관적 음성평가는 음성의 상태를 모두 대변할 수은 없으며 객관적인 음성평가에 대한 보완적인 의미를 가진다. 현재 개발되어 있는 주관적 음성평가 방법들이 유용한 평가도구이긴 하지만 나름대로의 문제점과 제한점을 가지고 있기 때문에 이에 대한 개선과 보완을 위한 지속적인 연구와 개발이 요구된다.

후두 미세 수술을 받은 환자에서 수술 전과 후 전체적인 음성 장애 지수를 비교했을 때 모두 호전이 있는 것으로 나타났다. 영역별로는 기능적, 물리적 영역에서는 남녀간의 차이가 없었으나 감성적 영역에서는 여자보다 남자에서 수술 후 만족도가 큰 것으로 나타났다. 이번 연구를 통해 음성 장애 지수가 음성의 상태를 모두 대변할 수는 없지만 객관적인 음향, 공기역학적 검사로 평가할 수 없었던 음성 장애에 대한 환자의 인식 정도를 정량화하여 평가할 수 있는 편리한 도구임을 확인 할 수 있었다.

This paper will discuss the difference between self assessment of voice disorders and the hearer voice assessment of a comparative group of normal subjects. The study was conducted on 25 voice disorder subjects and 32 hearers of a comparative group of normal subjects. The results are as follows. Firstly, in K-VHI and VHI-H, the hearers of the comparative group of normal subjects perceived more serious voice disorders than the voice disorder group in all sub-domains. Likewise, in K-VQOL and VRQOL-H, the hearers of the comparative group of normal subjects perceived more serious voice disorders than the voice disorder group in all sub-domains. Secondly, the hearer voice assessment of the comparative group of normal subjects showed no difference in gender regarding the perception of the severity of voice disorder issues. Thirdly, the hearer voice assessment of the comparative group of normal subjects states that in the emotional aspects of VHI-H, professional voice users perceive more serious voice disorders than others. Accordingly, in VRQOL-H, there was no difference in use of the voice between professionals and others.

Voice disorders are most common in female teachers due to work-related vocal demands; however, only a few studies tried to evaluate individual risk factors with work-related risk factors to diagnose voice disorders. This study evaluated sixty-seven female elementary teachers (36 with voice disorders and 31 without voice disorders) to compare their vocal misuse, overuse, and vocal hygiene behaviors. Total Voice Handicap Index scores and VHI subscale (P, E, F) scores were not significantly different between two groups (p>0.05) and there was no relationship between VHI and acoustic measures (p>0.05). Loud talking, talking in noisy situations, and excessive speaking were significantly more frequent in female teachers with voice disorders (p<0.05) and thereby these overuse and misuse behavioral patterns were identified as risk factors to develop voice disorders in female teachers. Also, hydration was the most common behavior for vocal hygiene when experiencing vocal fatigue; however, hydration with hot green tea or coffee and throat clearing were often misused for vocal hygiene. This study found that female teachers from both groups presented higher voice handicap regardless of voice disorders. This study suggests a multidimensional voice assessment protocol is required to reflect voice problems in teachers and a vocal education program may be important to improve vocal hygiene knowledge and behavioral changes in female teachers.

The study examined that parents and teachers were aware of what extents behavioral characteristics were related to the children's voice problems. The voice samples of 89 children in the ages of 3 to 5 were collected and their voice quality were graded by G scale of GRBAS. The parents and teachers of the children were asked to complete the questionnaire composed of the pediatric Voice Handicap Index (pVHI) and the psycho- and voice behavioral characteristics of their children. The results are as follows. First, there were no significant differences in both pVHI and behavioral characteristics of their children by G scale. However, significant differences were shown in the behavioral characteristics between parents and teachers, but no difference in pVHI between them. In addition, there was a significant correlation between the psycho-behavioral characteristics and the voice behavioral characteristics in both parents and teachers. These results represent that parents and teachers are not aware of the presence of their children's voice problems and such voice problems are affected by behavioral characteristics associated with the use of voice.

Objectives : The purpose of this study is to evaluate the voice handicaps of the idiopathic Parkinson's Diseases (PD) and their voice-related quality of life. Methods : Voice handicap index-10 (VHI-10) and Voice related Quality of Life were completed by 17 idiopathic PD patients, and Unified Parkinson's Disease Rating Scale (UPDRS) part I, II, III were assessed. The relations between VHI-10, VRQOL and UPDRS scores were analysed. Results : VHI-10 score of PD patients was $14.35{\pm}8.07$ and VRQOL total score of PD patients was $59.12{\pm}20.25$, social-emotional $59.93{\pm}20.50$, physical function $58.58{\pm}21.77$. There were significant relations between VHI-10, VRQOL score and UPDRS II (activities of daily living). Conclusions : These results suggest that voice impairments affect the daily living of PD patients and their quality of lives.

Background and Object: The aim of this study is to evaluate the change of patient's subjective voice handicap index (VHI) and acoustic parameters before and after laryngeal microsurgery for benign vocal cord disease. Materials and Method: We analyzed 78 patients who received laryngeal microsurgery for benign vocal cord disease from January 2004 to February 2007 retrospectively. There were 28 vocal polyp, 40 vocal nodule, 5 intracordal cyst and 5 Reinke's edema. Jitter, shimmer, harmony to noise ratio (HNR) were analyzed before surgery and 2-3months after surgery using the Doctor's speech science program. The voice handicap index introduced by the Pittsburgh Voice Center was used to examine patient's subjective change of voice quality. Results: Acoustic parameters of jitter, shimmer and HNR were improved in patients with vocal polyp and vocal nodule after surgery. The acoustic parameters were not improved in patients with Reinke's edema, statistically. Only jitter was improved significantly in patients with intracordal cyst (p<0.05). The VHI was significantly improved after surgery. The change of jitter and shimmer was significantly correlated with the change of VHI after surgery. Conclusion: The acoustic parameters and VHI were significantly improved in patients with benign vocal disease after laryngeal microsurgery.
