Cultural, social, economic and other various environmental factors affect our language and different words and terminology are used and coined for different contexts, resulting in quantitative change of vocabulary. This paper presents an automatic pronunciation generator using selection procedure for exceptional pronunciation words from added text corpus, which reflects this dynamic nature of language. For our experiment, we used the text corpus released by ETRI for speech recognition. consisting or 53,750 sentences (740.497 Eojols), and obtained a 100% performance level of the proposed automatic pronunciation generator.

This study is concentrated to search for the effective teaching method of Korean pronunciation as one of Korean language teaching for the chinese. Pronunciation is the most basic factor in the use of language. pronunciation is the basic factor for learners to judge the fluency and accuracy of the target language in the process of communication. but people usually learn the second- language when they are adults, who are surely influenced by mother language. Therefore, it is the main purpose of this thesis to seek vocal sound system and phonological phenomena in Korean and Chinese and figure out the common and difference of these two languages through contrastive analysis.

In this paper, we propose the stochastic pronunciation lexicon model for large vocabulary continuous speech recognition system. We can regard stochastic lexicon as HMM. This HMM is a stochastic finite state automata consisting of a Markov chain of subword states and each subword state in the baseform has a probability distribution of subword units. In this method, an acoustic representation of a word can be derived automatically from sample sentence utterances and subword unit models. Additionally, the stochastic lexicon is further optimized to the subword model and recognizer. From the experimental result on 3000 word continuous speech recognition, the proposed method reduces word error rate by 23.6% and sentence error rate by 10% compare to methods based on standard phonetic representations of words.

The purpose of this study is to compare and analyze phonetic items such as the phonemic system, phonological rules, and pronunciation descriptions and notations incorporated in the textbooks. Based on our analysis results, we point out the problems related to pronunciation education, and suggest directions for improvement. First, the presentation order of consonants and vowels in the phonological systems sections of each textbook was different. We recommend that a standard for consonant and vowel presentation order should be prepared, but that this standard should take into consideration the specific purpose of the textbook; the learning strategies and goals, as well as the possibility of teaching and learning. Second, similar to phonemic systems, the presentation order of phonological rules was different for each textbook. To create a standard order for phonological rules, we have to standardize the order of presentation of rules and determine which rules should be presented. Furthermore, when describing phonological rules, the content should be described in common and essential terms as much as possible without the use of jargon. Third, in other matters of pronunciation, there were problems such as examples for pronunciation and lack of exercises. Regarding this, we propose to provide sentences or dialogues as examples for pronunciation, and to link these to various activities and other language functions for pronunciation practice.

우리말에서 띄어쓰기와 버금갈 정도로 어려운 것이 우리말의 발음이다. 이에 실생활에서 혼란스럽게 사용되는 발음법과 그로 인해 올바른 발음의 선택에 대한 어려움을 덜어낼 수 있도록 표준어 규정의 표준 발음법에 따른 한국어 음소열 자동 생성기를 구현하여 교육용으로 쓸 수 있도록 하는 것이 이 논문의 목적이다.

이 논문은 일본의 호리따씨가 1983년 8월 고베시에서 열린 제4차 세계음성학자 대회에서 발표한 내용의 영역본이다. "음성언어의 직감적 개발"이란 부제가 붙은 "위이훠 방법"이란 호리따씨가 개발해 낸 농아와 그 밖의 언어장애자의 발음 훈련 및 교정법인데, 혀의 감각이 둔한 장애자의 혀에 종이같이 얇은 고자 조각을 붙여서 발음하게 함으로써 정확한 조음 위치를 파악하여 올바른 발음을 익히도록 하는 방법이다. 대회에서도 상당한 관심을 끈 논문이므로 우리나라의 언어치료계를 위하여 소개한다. 이 방법은 음성훈련 및 외국어의 발음교육에도 이용될 수 있을 듯 하다.

본고는 일본어화자의 한국어 학습에 나타나는 발음상의 제문제를 논한다. 문제점은 초급, 중급의 단계별로 고찰할 필요가 있고 또한 학습자의 이론적인 인식상의 문제와 학습자의 실제 발음 실천상의 문제를 구별해서 검토할 필요가 있다. 본고에서는 모음, 자음, 음운변화 및 표기상에 나타나지 않는 발음의 문제 등, 음운단위에 관한 요소, 그리고 높낮이(pitch)와 억양(intonation) 등, 운율적인 요소를 다루었다. 서울말의 높낮이에 대한 기술도 시도하였다.

One of the most important means in modem NQ (Network Quotient) emphasized society is the communication skill. Therefore, it is mostly necessary to accurately express his or her own idea and maximize own communication competence. For this, efforts on improving pronunciation accuracy, such as pronunciation stretching practice and vocal cords reflex point acupressure therapy, have been devoted for communication competence in daily life. However, objective and positive method to substantiate such efforts has not yet been studied to find if the methods can improve pronunciation accuracy in effect. We, therefore, propose an IT based method of substantiation and quantization for such pronunciation accuracy improvement methods. Voice analysis on voice data sample of 30 males in 20s, before and after pronunciation stretching practice and vocal cords reflex point acupressure, has been performed in this paper.

In this paper we extracted control rules of synthetical pauses and syllable durations depending on pronunciation speed in Korean speech from the spoken sentences recorded by 18 professional announcers. Pause rules were divided into three categories : pause between sentences(PBS), pause between clauses(PBC) and pause between intonational phrases(PBI). From the analysis results it is found that comparing the slowly spoken sentence with the fast spoken sentence the duration difference between them is due to the synthetical pause increments, expecially, of PBS and PBC. In addition, it is also found that the increment ratio of the mean syllable duration Is low. On the other hand, PBI was not pronounced in the fast spoken sentences. PBI was pronounced at the pronunciation speed(PS) over some PS.

사용자가 컴퓨터와 자연스럽고 인간적으로 대화할 수 있고, 사람의 요구에 지능적인 해답을 능동적으로 제시할 수 있는 사용자 인터페이스 에이전트가 활발히 연구되고 있다. 음성, 펜, 제스쳐인식 등을 비롯한 다양한 방법을 통하여 사람의 의사전달방식을 컴퓨터의 입력수단으로 구현하여 사용자 편의성을 도모하고 있다. 본 논문에서는 컴퓨터를 블랙박스로 하고, 표면적으로 지능형 3차원 그래픽 얼굴 에이전트와 사용자가 의사소통을 하는 사용자 인터페이스를 대상으로 하였다. 컴퓨터가 단순문제 해결을 위한 도구에서 많은 정보를 다양한 매체를 통해 제공하는 보조자의 역할을 수행하게 되었기 때문에 위의 방법은 보다 적극적인 방법이라 할 수 있다. 이를 위한 기반 기술로써 국어를 발음하는 얼굴 애니메이션을 연구하였다. 발음을 표현하기 위한 데이터로써 디지털 카메라를 사용하여 입술 운동의 특징점의 위치를 조사하였고, 모델링 시스템을 개발하여 데이터를 입력하였다. 적은 데이터로도 복잡한 자유곡면을 표현할 수 있는 B-Spline곡면을 기본데이터로 사용하였기 때문에 애니메이션을 위한 데이터의 양 또한 줄일 수 있었다. 그리고 국어음소의 발음시간 수열에 대한 입술모양의 변화를 조사하여 발음소리와 입술 움직임을 동기화 시킨 발음 애니메이션을 구현하였다.
