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.

Backgroud : Now a days, most studies for professional voice user have been performed after artificial voice abuse without consideration of environmental and personal factors, and occupational specificity, therefore those studies have some problems. Objectives : To make a basic guideline for the management of untrained professional voice user, practically we ananalyzed the voice of experimental group. Materials and methods : Just after working, the sustained vowel sounds of the 15 female telephone operators (subjective group) and the 20 normal female persons (control group) were analysed, using a history paper, acoustic analyzer and videostroboscopy. Results : The most common symptom in subjective group was dysphonia. Stroboscopic findings in subjective group were as following ; posterior chink 11 cases (73%), incomplete closure 2 cases (13%), anterior chink 1 case (7%). The mean maximal phonation time in telephone operators was 12.8 seconds and in control group was 16.8 seconds. Jitter, pitch pertubation quotient (PPQ), shimmer and amplitude pertubation quotient (ASQ) were significantly increased in subjective group than control group, but there is no difference between two group in fundamental frequency and noise to harmonic ratio. Conclusion : Untrained professional voice user needs professional career guidance and counseling. And when we manage the untrained professional voice user, we should consider specific occupational, personal and environmental factors as well as laryngeal factors.

This survey was to identify voice symptoms and vocal-health service related experiences of occupational voice users(teachers, telemarketers, speech therapists). The 91.8% of teachers, 97.9% of telemarketers, 86% of speech therapists surveyed reported more than one voice symptom. The symptoms were classified as 9 categories(running a temperature, getting dry, dry and cough, pain, phlegm, tingled, hoarseness, cracks, swollen) and the most frequently reported from 3 groups was 'getting dry'. The 85.7% of teachers, 87.8% of telemarketers, 66% of therapists surveyed had no experience of vocal-health related services. The 19.6%, 19.9%, and 72% of each group reported they have heard both of 'voice/speech therapist'. The 36.8% of teachers and 43.6% of telemarketers answered they don't know how to use their voice efficiently and 45.3% of the teachers, 43.6% of the telemarketers, 28% of the therapists surveyed asked professional help for their voice. The result showed that most of the occupational voice users surveyed experienced voice symptoms but rarely knew professional vocal-health related services.

As the range of professional voice users are expanding, interest towards voice increases as well. Especially as teachers compose the occupational group, exposed to high risk of voice disorder, it is necessary to identify the cause of speech problems and speech disorders. The purpose of this study is to analyze the voice characteristics of teachers and to investigate the causes of voice disorders. From 2000 to 2018, 414 studies were found under a combinated set search words of 'profession', 'Teacher', 'Professional Voice User', 'Voice', 'Voice disorders', 'Risk' and out of them, 8 studies were selected as final focus analysis subjects. The qualitative evaluation was carried out by modifying the Quality: checklist for assessing the Risk of bias. The study confirmed that voice misuse frequently occurred to teachers when they used their voice and this feature was affected by the environment. These results suggest that environment improvement of teachers' speech abuse and consistent voice education are necessary.
