This study aimed to provide knowledge helpful for understanding voice problems related to occupations in the clinical field through an investigation and comparison of subjective vocal symptoms of 12 professional actors and 12 speech-language pathologists Among the 11 symptoms, "Difficulty with high pitch when singing," "Hypertension in the neck when speaking," and "Feel voice fatigue" were the most frequent symptoms in both groups. Additionally, the professional voice users reported a higher frequency of "Difficulty with high pitch when singing" (p=.049), "Hoarse voice" (p=.021), "Difficulty (requiring effort) when speaking" (p=.032), "Pain in the neck when speaking" (p=.009), and "Feel vocal fatigue" (p=.018) than the elite vocal performer group. This may be due to the different voice-related environments and differences in voice demands during occupational activities between the two groups.

폐쇄성 수면무호흡의 치료를 목적으로 한 구개수구개인두성형술 이후의 음성변화 유무를 파악하여, 성악가 등의 전문적인 음성사용자에게 상기한 수술을 결정함에 있어서 가능한 guideline을 제시하여 보고자 하였다. 수면다원검사상 폐쇄성 수면무호흡증으로 진단된 성인남자 20명을 대상으로 수술전후의 음성변화에 대한 설문조사를 하였고, 수술전, 수술후 1개월에 각각 /아/, /이/, /우/ 모음의 제1, 2, 3 음향대를 비교하였으며, 표준 비음비율이 각기 다른 세가지 문장을 이용하여 수술전후의 비음비율의 변화를 측정하였다. 환자 자신은 수술전후의 음성이나 음색의 변화를 느낄 수 없었고, 비음비율의 변화나 모음의 음형대에 대부분은 변화가 없었지만, /우/ 음의 제3음형대 특성에 변화가 있음을 관찰하였고, 구인두가 중요한 역할을 담당할 수 있는 특정언어의 일부 발음이나 vibrato, singer's formant등의 변화유무에 대한 연구가 없는 점을 감안한다면, 성악가를 비롯한 전문적 음성사용자에？서는 구개수 구개인두성형수술을 결정함에 있어 신중을 기하여야 할 것으로 사료되었다.

본 연구에서는 음성메모 기능을 통해 스마트폰에서 메모를 편리하게 작성할 수 있는 방안을 제안하였다. 이 제안은 취약 계층을 포함한 다양한 사용자들이 스마트폰을 보다 쉽고 효율적으로 활용할 수 있는 기회를 제공한다. 음성메모를 통해 중요한 정보를 빠르게 기록하고, 필요할 때 언제든지 액세스할 수 있으며, 기억력에 의존하지 않고 안정적인 방식으로 정보를 보존할 수 있다. 이러한 기능은 취약 계층을 위해 스마트폰 사용의 장벽을 낮추어 정보 접근과 활용의 평등성을 증진시킬 것으로 기대된다. 또한, 연구 결과는 스마트폰 기술과 사용자 경험 분야에 대한 심층적인 이해를 제고하고, 향후 관련 연구와 개발에 영향을 미칠 것으로 기대된다.

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.

The purpose of this study is to investigate the problems of the rapidly increasing voice interface and to find out what results will be obtained when the new gesture interaction is applied to the product, and to suggest the improvement method for a better user experience. Through the literature review, I have conducted a theoretical review on the changes in the product interface used in the product and the difference between them, and then conducted in-depth interviews on the 20-30 users who used voice recognition as a product trigger. As a result, it was concluded that the decline in the reliability of accuracy leads to a decrease in the preference of voice recognition interactions and an needs of appropriate interface for the functional aspect of non-relavancy in physical distance as a product trigger. This study is meaningful in that it has found a problem with the study of the product trigger interface and suggested improvement measures, and hope to be helpful in follow-up study.

최근 기존 PSTN망을 이용하던 음성전송방식이 VoIP 기반의 인터넷 전화 서비스로 바뀌어가고, 그 사용수도 늘어가는 추세이다. 그와 동시에 악의적인 사용자에 의한 도청, 피싱 등의 사건이 일어나면서 VoIP 보안 이슈가 늘어가고 있다. 본 논문에서는 이러한 보안 이슈들에 대한 해결책으로 SIP의 사용자 인증을 신뢰받는 기관에서 UA를 인증하여 사용자 인증에 대해 안정성을 강화하는 보안 프로토콜을 제안한다.

Mean F0, Jitter, Shimmer, and NHR were measured in 21 opera singers, 13 Korean traditional 'pansori' singers, and 21 non-singers. Four voice sampling conditions were ordinary /α/ prolongation, /α/ prolongation using vocal technique as if the subjects were singing, oral reading of the words of a song, and singing. One-way ANOVA and Sheffe post-hoc analysis were used to identify significant differences among the groups. The mean F0 was significantly different among the 3 groups in all conditions except for the ordinary /α/ prolongation condition. The opera singers produced lower jitter and NHR compared to 'pansori' singers and non-singers only in the singing condition.

This study examines the effectiveness of semi-occluded vocal tract exercise (SOVTE) conducted through telepractice for 10 female teachers who have experienced vocal discomfort while working in early childhood education facilities (childcare centers, kindergartens). The effects of SOVTE conducted through telepractice were evaluated based on the Korean voice handicap index (KVHI), the Korean version of the voice activity and participation profile (K-VAPP), vocal effort, and auditory perception evaluation by using the grade, roughness, breathiness, asthenia, and strain (GRBAS) scale. The results show that total, functional, and physical scores of KVHI significantly reduced after SOVTE. The total score in K-VAPP significantly reduced after SOVTE. Moreover, vocal effort significantly decreased after SOVTE. However, statistically significant differences were not noted in GRB scales before and after SOVTE. In conclusion, early childhood teachers experienced reduced vocal discomfort SOVTE conducted through telepractice. The study results indicate that voice therapy conducted through telepractice is an effective method for reducing vocal discomfort in early childhood teachers.

Speech recognition and motion recognition technologies are applied and used in various smart devices, but they are composed of simple command recognition forms and are used as simple functions. Apart from simple functions for recognition data, professional command execution capabilities are required based on data learned in various fields. Research is being conducted on a system platform that provides optimal data to users using Generative AI, which is currently competing around the world, and can interact through voice recognition and motion recognition. The main technical processes designed for this study were designed using technologies such as voice and motion recognition functions, application of AI technology, and two-way communication. In this paper, two-way communication between a device and a user can be achieved by various input methods through voice recognition and motion recognition technology applied with AI technology.
