Intelligibility measurement is one criterion for the assessment of the severity of speech disorders especially of dysarthric persons. Rate control, usually rate reduction, is used with many dysarthric speakers to improve their intelligibility. The purpose of this study is to compare how change intelligibility of speech produced by cerebral palsic speakers according to three speaking conditions. Speech samples were collected from 10 adults with cerebral palsy were asked to speak under three speaking conditions-(1) naturally(control), (2) more slowly(rate control), (3) louder and accurately(clear speech). In a perception test, after listening to the speech samples, a group of three judges were to write down whatever they heard. The result showed that total cerebral palsic subjects were divided into two subgroups according to their intelligibility according to three speaking conditions. Some subjects showed that speech intelligibility increased greatly if asked to speak 'louder and more accurately'. and the others showed no difference of intelligibility according to the speaking conditions. This study suggested that it would be useful clinically to find out the best instruction to improve intelligibility suitable for each speaker with cerebral palsy.

The purpose of this study is to investigate the relations between phonetic differences among Korean learners' production of English front vowels, pronunciation intelligibility and speaking proficiency test score. To do so, thirty Korean university students were asked (1) to read English text book paragraphs and (2) describe a picture. Two English native raters and one Korean rater evaluated Korean subjects' English pronunciation intelligibility and speaking. In addition, subjects' English vowel productions were acoustically analyzed(F0, F1, F2, vowel duration, intensity). The results of the study show that the vowel quality and pitch of the unstressed vowels and lax vowel are related to the pronunciation intelligibility. In addition, the scores of pronunciation intelligibility and speaking are highly related.

This research mainly focuses on intonational characteristics of synchronous English speech. Intonation contours were extracted from 1,848 utterances produced in two different speaking modes (solo vs. synchronous) by 28 (12 women and 16 men) native speakers of English. Synchronous speech is found to be slower than solo speech. Women are found to speak slower than men. The effect size of speech rate caused by different speaking modes is greater than gender differences. However, there is no interaction between the two factors (speaking modes vs. gender differences) in terms of speech rate. Analysis of pitch point features has it that synchronous speech has smaller Pt (pitch point movement time), Pr (pitch point pitch range), Ps (pitch point slope) and Pd (pitch point distance) than solo speech. There is no interaction between the two factors (speaking modes vs. gender differences) in terms of pitch point features. Analysis of sentence level features reveals that synchronous speech has smaller Sr (sentence level pitch range), Ss (sentence slope), MaxNr (normalized maximum pitch) and MinNr (normalized minimum pitch) but greater Min (minimum pitch) and Sd (sentence duration) than solo speech. It is also shown that the higher the Mid (median pitch), the MaxNr and the MinNr in solo speaking mode, the more they are reduced in synchronous speaking mode. Max, Min and Mid show greater speaker discriminability than other features.

The purpose of this study is to examine the speaking rate(overall speaking rate and articulatory rate) of Parkinson's disease patients with palilalia(PDP). Palilalia is traditionally characterized by not only compulsive repetitions of words and phrases, but also by increased rate of speech based on auditory perception. Since Souques(1908) first characterized palilalia as fast speech rate from the perspective of auditory perception, few studies have evaluated PDP speech using acoustic methods. To compare the speech rate between PDP and normal subjects, we included five PDP and eight control subjects(age over 55), as well as the date acquired under reading tasks(standardized Korean paragraph). The difference in median of the overall speaking rate was not statically significant between the PDP group(median 5.25, IQR 1.30) and normal group(median 4.76, IQR 0.71). The PDP, however, had a significantly higher syllables per second on the articulatory rate(median 6.60, IQR 1.04) than normal subjects(median 5.60, IQR 0.52). Results indicated no differences in pause over 250msec and disfluency duration between the two groups. To provide useful insight into PDP speech, multiple levels of analysis should be employed.

언어학습에서 어휘는 가장 필수적이고 기본이 되는 단위임에도 불구하고 교육현장에서는 학생들에게 어휘를 지도하고 별도의 학습시간을 제공하는 경우는 매우 드물다. 어휘를 습득한다는 것은 소리 내어 말하고 듣는 과정을 통해 이루어진다. 눈으로 내용을 이해하고 암기하는 전통적인 언어 습득 방식은 분명 한계가 있을 수밖에 없다. 본 논문에서는 학습자 특성을 고려한 인지전략과 음성인식을 기반으로 한 Speaking 중심의 학습 방법을 연구하여 초등 영어 어휘 습득을 위한 인지전략 기반의 Speaking Training system을 설계하고 구현하였으며, 초등학교 5학년 두 개 학급을 선정하여 수준 테스트 후 실험 그룹과 비교 그룹으로 각각 편성하여 분석한 결과 학습자의 동기부여와 성취감을 높임으로써 학습자의 소리 영어 중심의 어휘 습득을 강화할 수 있었고, 학력향상 뿐만 아니라 학습참여도, 과제수행 정도, 흥미도 등의 자기주도적 능력까지도 향상시킬 수 있다는 놀라울만한 성과가 있었다. 본 연구를 통해 학생들의 실용적인 영어 말하기 능력을 향상시킬 것으로 기대한다.

Up to January 2003, the amount of English translated works of Korean Literature are 399, among which 170 are translated abroad, 189, in Korea, and 40, abroad as well as in Korea at the same time. Like other language speaking countries, the 1980s and the 1990s are peak not only for the translation of Korean Literature but also for its scholarly attention. The statistic analysis of information, accumulated in various databases such as The Harvard Korean Studies Bibliography, Hawaii Korean Studies Bibliography, and MLA International Bibliography, shows that up to February 2004, 33 books, 16 dissertations and one thesis, 200 articles, and 84 reviews are wholly devoted to the study of Korean Literature in English speaking countries. However, why certain works of poets like Kim Sowol, Han Youngun, So Chungju, and novelists like Hwang Sunwon, Han Moosook, Kim Dongri are mostly translated in English speaking countries remain to be analysed in their socio-political details in breadth and depth. Likewise, why the works of So Chungju, Yi Kwangsoo, Kim Manjoong, Han Youngun, Kim Sowol, Chung Jiyoung are mostly taught and studied in English speaking countries are open to further scholarly discussion and debate.

This paper is to help the students in elementary schools develop and improve their English listening and speaking skills by presenting effective teaching and learning techniques using puppetry. It is absolutely obvious that listening and speaking are very important skills for most EFL students. Using puppets in the classroom is a creative English teaching technique which can involve authentic, communicative language situations. Moreover, puppets appeal to children and can aid in lowering affective filters thereby creating a more comfortable learning environment. The study clearly showed that using puppets is feasible and enjoyable in elementary English classes. However, caution must be exercised in drawing and generalizing conclusions from this experience. The results of the experiment are as follows: First, using puppetry in the English class was found to have positive influence on students' affective domains (interst, attitude). Second, using puppets in the English classes was found to be efficient for improving students' English listening and speaking skills. Third, appropriate materials should be selected and well thought-out plans should be made to be successful English class using puppetry. Perhaps the most interesting line of future research is to use qualitative research to examine the effect of this technique on the teacher variable. Further research is recommended, especially on using puppetry for speaking proficiency and creating affectively comfortable learning atmospheres.
