  • 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.

  • 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 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.

  • Studies on the risk factors of voice disorders in Korean adults are rare. I evaluated the association between the duration of self-reported voice problem and voice disorders in Korean adults. Data were from the 2008 Korea National Health and Nutritional Examination Survey. Subjects were 3,135 people (1,310 men and 1,825 women) aged 19 years and older. Multi-nominal logistic regression analyses were used to examine the association between the duration of self-reported voice problem and voice disorders. The prevalence of self-reported voice problems was 5.9% among Korean adults. Adjusting for covariates (age, sex, education level, length of employment, tobacco consumption, alcohol consumption, thyroid disorders, pain and discomfort during the last two weeks), self-reported voice problems lasting longer than three weeks were independently associated with functional voice disorders (OR=5.30, 95% CI: 3.30-8.50) and organic voice disorders (OR=4.84, 95% CI: 1.82-12.89). Self-reported voice problems in the past three weeks were significantly associated with functional voice disorders (OR=3.64, 95% CI: 1.84-7.19), but not significantly associated with organic voice disorders. Self-reported voice problems are prevalent among adults. This study highlights that self-perception of a voice problem for more than three weeks is related to functional voice disorders and organic voice disorders.

  • This research was conducted to investigate the voice related needs of occupational voice users. The data collected from teachers(379), tele-marketers(156), therapists(50) was classified according to its content, by colaizzi's inductive categorical analysis. The voice related needs are classified into 3 big categories, 1) how to use, 2) how to care, 3) how to be healthy. Again the category 'how to use' my voice was into 6 sub-categories: (1) efficiently, (2) as I desired, (3) without pain(discomfort), (4) expressively, (5) phonation (methods) and (6) clear articulation. The result showed that the needs from 3 groups of occupational voice users reflect their own environment which they have to use their voice as well as the voice characteristics wanted from their specific listeners.

  • VoiceXML (Voice extensible Markup language)은 음성 대화를 웹의 마크업 언어로 기술할 수 있는 차세대 대화형 음성 서비스를 위한 표준이다. 현재 발표된 VoiceXML 1.0 사양은 음성대화의 기술에 초점을 두고 있으며, 음성 서비스의 시작 시점에 관해서는 언급이 없다. 본 논문에서는 사용자에 의해 시작하는 주문형 (on-demand) 음성 서비스 (inbound call) 뿐만 아니라, 최근에 고객관계관리 (CRM: Customer Relationship Management) 등에서 요구되는 시스템에 의한 푸쉬형 음성 서비스 (outbound call)가 가능한 VoiceXML 플랫폼을 설계하고 구현하였다. 또한, 본 논문에서는 W3C (World Wide Web Consortium)의 호 제어 요구사항 (Call Control Requirements)을 바탕으로 음성 대화 중에 팩스 송수신이 가능하도록 VoiceXML 문서형 정의 (UTD: Document Type Definition)를 확장하였다.

  • 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.

  • The purpose of this study was to analyze the association between self-reported voice problems and voice disorders in the Korean adult population. Data were collected from the 4th Korea National Health and Nutritional Examination Survey (2008) from 3,135 subjects (1,310 men and 1,825 women) aged 19 years and older. Multi-nominal logistic regression analyses were used to examine the association between self-reported voice problems and voice disorders in the Korean adult population. Adjusting for covariates (age, sex, education level, job, smoking, alcohol drinking, thyroid disorders, pain and discomfort during the last 2 weeks), self-reported voice problems included independently associated functional voice disorders (OR=4.70, 95% CI: 3.14-7.03) and organic voice disorders (OR=3.89, 95% CI: 1.57-9.65). The results of the present study verified that self-reported voice problems are valuable indicators for voice disorders. Further research is needed to ascertain the effect of self-reported voice problems on voice disorder in adults.

  • Background and Objectives : Patients with so-called 'functional voice disorders' who have structurally normal larynges and demonstrate muscle misuse in the larynx, and those with several interacting causes including habitual muscle tension, are probably better defined as having a 'muscle misuse voice disorder'. The purpose of this study was to analyze the voice and effectiveness of voice therapy in patients with functional voice disorders and to provide a guide for the treatment of functional voice disorder. Materials and Method : The records of 35 patients, presenting with functional voice disorder and receiving voice therapy during October, 2001 to September, 2002, were reviewed. Prior to voice therapy, the stroboscopic examination of their larynx, aerodynamic and acoustic analysis was done. The results of voice therapy were compared according to the patient's subjective, perceptual evaluation of voice, and maximal phonation time. Results : Patient's subjective, perceptual evaluation, and maximal phonation time showed superior results after voice therapy. Conclusion : The result of this study indicates that voice therapy is an effective treatment method of patients with functional voice disorder, especially muscular tension dysphonia.

  • 본 논문에서는 철도예약서비스를 위한 SIP를 기반으로 하는 텔레포니 환경에서의 VoiceXML을 이용한 실시간 음성인식을 구현하는 방안을 제안하였다. 제안된 방법은 PSTN 또는 인터넷을 통하여 들어온 음성신호를 VoiceXML을 이용한 Dialog 처리를 하고 전송된 음성신호를 음성인식 시스템에서 처리하여 출력된 결과값을 VoiceXML의 Dialog에 반환하여 사용자에게 전달하는 방식이다. VASR 시스템은 Dialog를 처리하는 Dialog 서버, 음성신호를 처리하기 위한 APP서버, 그리고 음성인식을 처리하는 음성인식 시스템으로 구성된다. 본 논문에서는 텔레포니 환경에서의 음성신호 처리를 위하여 VoiceXML의 Record Tag 기능을 이용하여 음성신호를 녹음하고 이를 실시간 재생하여 음성인식 시스템으로 전송하는 방식을 구현하였다.
