Subjective voice evaluation is necessary and important to assess the voice disorders in addition to objective voice evaluation. Subjective voice evaluation is divided into examiner and examinee subjective voice assessment. The examiner assessment represents perceptual judgment to the patient's voice such as GRBAS scale, Buffalo voice profile, consensus auditory perceptual evaluation of voice (CAPE- V) and so on. The examinee assessment consists of indirect method including voice handicap index (VHI), voice outcome survey (VOS), voice symptom scale (VoiSS), voice related quality of life (V-ROQL) and direct method which is called patient's self-subjective voice rating. This review article describes a general rule, advantages and pitfalls about GRBAS scale, VHI and patient's self-subjective voice rating which are presently most representative voice assessment tools.

Background and Objectives:The Voice Handicap Index (VHI) evaluates the patients perception of impact of voice disorder in term of functional, physical, emotional factors. The purpose of this study was to evaluate the change of patient's subjective voice handicap index before and after laryngeal microsurgery for benign vocal cord lesions. Materials and Methods:We analyzed 55 patients who received laryngeal microsurgery for benign vocal cord disease from January 2011 to February 2013 retrospectively. There were 50 vocal nodules, 3 vocal polyps, 2 vocal cysts. VHI were analyzed before surgery and 3 months after surgery. Results:The VHI scores showed statistically significant reductions postoperatively in functional and emotional VHI (p=0.01 and p=0.034). Also, Emotional VHI score after microsurgery was higher in female than male [adjusted odd ratio (AOR)=0.292 ; 95% confidence interval, CI=0.098-0.869, p=0.01]. Conclusion:In other words, males experience significant more emotional effects that are improved after microscopic surgery.

The purpose of this study is to evaluate the prevalence of voice disorders and the Korean voice handicap index in the elderly. For this study, 169 elderly performed two types of questionnaires and vowel /a/ prolongation. Self-reported voice symptoms and the Korean voice handicap index were analyzed and acoustic voice evaluation was performed by MDVP. The results showed that the prevalence of voice disorders in the elderly are significantly higher than that of adults in self-reports. In acoustic evaluation, 32.2% of the male elderly and 40.9% of the female elderly exceeded the thresholds of Jitter (%), Shimmer (%) and NHR. In addition, Korean voice handicap index scores of the female elderly are significantly higher than those of female adults. These findings indicate the high frequency of voice disorders in the elderly and the need to focus on this group. Additional studies on the voice related quality of life for the elderly are needed.

Objectives : The purpose of this paper is to know the efficacy of voice therapy for vocal fold nodules in children. Materials and Methods : Sixty two patients with vocal nodules(46 boys and 16 girls) were retrospectively reviewed. Age ranged from 4 to 15 years with mean age of 8 years. Questionnaire survey was carried out with voice handicap index, at pretherapy and post-therapy(3 months and 5 years after voice therapy). Results : Sixty two percent of the patients showed improvement by voice therapy. Twenty five patients continued education at home after voice therapy, but only eight childrens were included this group in pre-school aged children. Voice handicap index was improved in 3 months and 5 years after voice therapy. In contrast, pre-school children group showed slight aggravation in 5 years, especially in emotional subdomain. Conclusion : Voice therapy is effective primary treatment in children with vocal fold nodules. Different result between preschool aged children and school aged group shows needs for age specific approach of voice therapy.

Background and Objectives : Voice disorder is recognized as a major problem because it negatively affects the elderly's social participation and quality of life. The purpose of this study was to examine the validity and reliability of Korean aging voice index (KAVI), which assesses the quality of life related to the voice of the elderly. Materials and Method : This study was conducted on 211 elderly people aged 65 years or older : 111 patients with voice disorder (mean age 69.8, range 65-80 years) and 100 nomorphonic participants (mean age 70.6, range 65-82 years). Aging voice index was translated into Korean and used and Korean voice-related quality of life (KVQOL) was conducted to verify KAVI. The validity (item validity, concurrent validity, and construct validity) and reliability (test-retest reliability and internal consistency reliability) of KAVI. Results : The item validity (ICC=0.895) and construct validity (r=0.765) showed a high correlation, respectively. And concurrent validity (r=0.748), test-retest reliability (0.851), and internal consistency reliability (${\alpha}=0.832$) were statistically significant in voice disorder group. In addition, there was a significant difference between the voice disorder and the nomorphonic group in AVI total score. Conclusion : KAVI is a validated and reliable quality of life tool that will be useful for assessing the presence and effectiveness of interventions in clinical settings.

Speech language pathologists depend on their voice for livelihood and are high risk group of voice disorders. But there are few studies on their prevalence of voice symptoms and voice handicap index. This study aimed to evaluate prevalence of voice symptoms and Korean voice handicap index with 86 speech language pathologists and 90 individuals employed in other occupations. We analyzed self-reported voice symptoms and voice handicap index using a questionnaire for this study. The results showed that the prevalence of voice symptoms of speech language pathologists is 60.5% and voice handicap index scores of speech language pathologists group are significantly higher than those of control group in physical and total score. And we found that alcohol history was a risk factor for voice symptoms. These findings indicate that special vocal hygiene program for speech language pathologists and follow up studies for comparisons of prevalence of voice symptoms and voice handicap index with other professional voice users are necessary.

Background and Objectives : The aim of this study is to introduce Korea version of pediatric VHI and to compare pVHI-K scores between children with dysphonia and children without voice problems before pVHI-K is developed as a preliminary study. Additionally, the relationship between pVHI and acoustic measures were investigated. Materials and Methods : pVHI-K scores in normal group were obtained from 15 parents who have children with no present or past history of a voice disorder, hearing loss, or related disability that can affect the their voice or speech. Dysphonia group consisted of 15 parents who have children with bilateral vocal fold nodule's at Department of Otolaryngology, the Seoul National University Hospital (SNUH). pVHI-K and acoustic parameters were measured in two group. Results : The mean pVHI scores (total, functional, physical, emotional) in normal group were 2.33 (T), 0.80 (F) 1.33 (P) and 0.27 (E), respectively whereas those of pVHI in children group with dysphonia were 23.13 (T), 11.07 (F), 5.73 (P) and 6.13 (E), respectively and significant differences were revealed in total pVHI score as well as in all of the sub-pVHI scores. Moreover, significant correlation between pVHI-K parameters (T, F, P) and acoustic measures [Shimmer(%)] were shown in children in dysphonia group. Conclusion : Reported by parents can be useful as a supplementary clinical tool for diagnosing and measuring treatment effectiveness in young children with dysphonia.

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.
