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.

본 논문에서는 외국어 학습 영역인 영어 듣기와 말하기 평가를 웹과 VoiceXML 기반 교육 평가 시스템을 이용하여 장소와 시간적 제한을 받지 않고 평가하는 방법을 연구하였다. VoiceXML 기반교육 평가 시스템은 사용자 등록 모듈, 평가 모듈, 평가 결과 모듈로 구성된다. 사용자 등록 모듈은 사용자 이름과 아이디, 비밀번호를 사용자 데이터베이스에 등록하여, 학습자가 평가를 하기 위해 전화를 했을 때 vxml 시나리오에 의해 제공되어지는 음성을 듣고 로그인을 하여 사용자를 확인할 수 있도록 하였다. VoiceXML 기반 전화 평가 시스템에서 출제자는 문제 출제와 평가, 평가 결과를 얻기 위한 시간, 노력을 경감할 수 있으며, 학습자는 언제 어디서나 유무선 전화기를 이용하여 VoiceXML 마크업 언어로 제공되는 시나리오에 의해 대화형 음성으로 제공되는 평가 문항을 듣고 직접 음성으로 평가함으로써 외국어 학습에 대한 효과를 올릴 수 있다.

The best method to study language is to talking with a native speaker. A voice recognition technology can be used to develope a language study machine. SD(Speaker dependant) and SI(speaker independant) voice recognition method is used for the language study machine. MP3 Player. FM Radio. Alarm clock functions are added to enhance the value of the product. The machine is designed with a DSP(Digital Signal Processing) chip for voice recognition. MP3 encoder/decoder chip. FM tumer and SD flash memory card. This paper deals with the application of SD ad SD voice recognition. flash memory file system. PC download function using USB ports, English conversation text function by the use of SD flash memory. LCD display control. MP3 encoding and decoding, etc. The study contents are saved in SD flash memory. This machine can be helpful from child to adult by changing the SD flash memory.

This article addresses the roles of the speech language pathologist (SLP) for singers who require prompt and effective treatment when a voice problem arises. The causes of voice problem are often vocal abuse/misuse/overuse, muscle tension dysphonia and inappropriate singing technique. The SLP should conduct voice counseling and voice assessment for maintaining healthy voice of singer constantly.

This study introduces an innovative model for zero-shot voice conversion that utilizes the capabilities of HuBERT. Zero-shot voice conversion models can transform the speech of one speaker to mimic that of another, even when the model has not been exposed to the target speaker's voice during the training phase. Comprising five main components (HuBERT, feature encoder, flow, speaker encoder, and vocoder), the model offers remarkable performance across a range of scenarios. Notably, it excels in the challenging unseen-to-unseen voice-conversion tasks. The effectiveness of the model was assessed based on the mean opinion scores and similarity scores, reflecting high voice quality and similarity to the target speakers. This model demonstrates considerable promise for a range of real-world applications demanding high-quality voice conversion. This study sets a precedent in the exploration of HuBERT-based models for voice conversion, and presents new directions for future research in this domain. Despite its complexities, the robust performance of this model underscores the viability of HuBERT in advancing voice conversion technology, making it a significant contributor to the field.

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.

Recently, Computer Assisted Language Learning (CALL) received widely held attention from diverse audiences. However, to the author's knowledge, relatively little attention was paid to the educational implications of voice recognition (VR) softwares in language teaching in general, and teaching and learning pronunciation in particular. This study explores, and extends the applicability of VR softwares toward second language research areas addressing how VR softwares might facilitate interview data entering processes. To aid the readers' understanding in this field, the background of classroom interaction research, and the rationale of why interview data, therefore the role of VR softwares, becomes critical in this realm of inquiry will be discussed. VR softwares' development and a brief report on the features of up-to-date VR softwares will be sketched. Finally, suggestions for future studies investigating the impact of VR softwares on second language learning, teaching, and research will be offered.

The purpose of this paper is to find prosodic characteristics in voice imitation. Speakers change various phonetic features in voice imitation. Speakers change their pitch ranges in the most cases. Especially, the pitch range is important for word conditions. And, as imitators change the voice, the average value of f0 is close to high frequence than low frequence or middle level.

In this paper, we explain telecommunication services based on spoken language information technology. There are three different kinds of services. The first is based on Advanced Intelligent services(AIN). We built a Intelligent Peripheral(IP)with speech recognition, speech synthesis and VoiceXML interpreter. The second is based on KT-HUVOIS, a proprietary speech platform based on VoiceXML. The third is based on VoiceXML interpreter. We explain various services depending on these platforms in detail.
