본 논문의 목적은 한국어 표준어와 경상 지역 방언의 한국어 모음 발음의 영어 모음 발음에 대한 영향을 연구하는데 있다. 데이터 자료는 한국인의 영어 발음 음성 코퍼스(Korean-Spoken English Corpus, K-SEC)를 활용하였다. 이중 일곱 개의 한국어 단모음이 포함된 단어와 열 개의 영어 단모음이 포함된 단어가 선정되어 분석되었다. 선정된 자료는 외국 거주 경험이 없는 성인 남성 표준어 화자와 경상 지역 방언 화자에 의해 발화되었다. 녹음된 코퍼스 자료의 포먼트 주파수는 음성 분석 프로그램인 Praat에서 제공하는 스펙트로그램을 통해 측정되었다. 녹음된 자료들은 포먼트 구역 그래프로 나타내어 분석되었다. 결과에 의하면, 한국어와 영어 모음의 발화에서 경상 지역 방언 화자가 강한 후설성을 보인 반면에 표준어 화자는 비교적 전설성이 강하게 나타났다. 또한, 표준어와 경상 지역 방언의 한국어 모음 발음 차이 (/으/, /어/)는 대치되는 영어 모음 발음(/ə/, /ʊ/)의 조음 방식에 영향을 미쳤다. 지역 방언의 사용과 무관한 한국인의 일반적인 모음 발음 특징은 영어 원어민 화자보다 조음 구역이 좁다는 것이다. 이에 한국인은 전반적으로 긴장 모음과 이완 모음을 구별하는 데 어려움이 있지만, 영어 원어민 화자는 모음 조음에 명확한 구분이 있다.

The aim of this study was to identify production difficulties of Korean learners of English in their articulation of English bilabial stops /p, b/ and labiodental fricatives /f, v/. Sixty non-sense syllables and twelve words were produced three times by nine graduate students. Test scores were measured from the score board made by FluSpeak, a speech training software program, which was designed for English pronunciation practice and improvement. Results show that 1) the subjects had lower scores in producing /p, b/ than /f, v/ from all positions, and 2) subjects had lower scores in medial (inter-vocalic) position than in initial (pre-vocalic) position and in final (post-vocalic) position when they produced /p/, /b/, /f/, and /v/. The results suggest that on the whole, Korean learners of English have much difficulty in producing /b/ and that they also have more articulatory problems in intervocalic than in the other positions when they produce these bilabial stops and labiodental fricatives.

The purpose, this experimental study was to identify pronunciation difficulties between male and female Korean speakers in their articulation of English vowels. Ten English mono-syllabic words were spoken six times by six male and six female college students. Formant frequencies were measured from sound spectrograms made by Pitch Works. Results show that Korean female speakers uttered English vowels more similar to those uttered by English native speakers than did Korean male speakers. While Korean male speakers could not readily distinguish between /i/ and /I/, /u/ and /v/, and /$\epsilon$/ and /ae/, respectively, Korean female speakers had difficulty only with /$\epsilon$/ and /ae/. The tentative results suggests that on the whole Korean speakers have difficulty in discriminating tense vowels from lax vowels, and they also have articulatory problems pronouncing low and back vowels such as /ae/. /a/ and /c/.

This study has two aim: one is to clarify the restructuring of English in utterance and the other is to make use of text-setting to be applied to getting accustomed to the English rhythm and pronunciation. Clitics prove to play a crucial role on the English restructuring, and are found to be attached to their previous and to their next head or host, thus forming, respectively, an on-cliticized rhythm, trochee and a pro-cliticized rhythm, iambus. En-cliticization proves to be preferred to pro-cliticization in most types of English rhythms. Accordingly, the restructuring turn out to occur all over the levels of the Prosodic Hierarchy. That is, syllables, words and clitic groups are restructured in poetry as well as in song words, which means the necessity of restructuring throughout the levels of the Prosodic Hierarchy from the syllable to the utterance. The present study suggests a good use of a rhythmic textsetting for learners of English to get accustomed to the stress-timed rhythm as well as to such changes in pronunciation as reductions, deletions, resolutions, contractions, and rhythms in English.

The purpose of this experimental study is to investigate and compare the. vowel lengths of English diphthongs and low vowels among native-English-speaking Americans with Korean college students from the Chungnam and Gyungnam provinces. Eight words and sixteen sentences were uttered five times by twenty five subjects from three groups; 1) Chungnam dialect speakers, 2) Gyungnam dialect speakers and 3) five native-English-speaking Americans. Acoustic features (duration) were measured from sound spectrograms made by the PC Quire. Results showed that the vowel lengths of English diphthongs and low vowels between native English speakers and Korean collegians of Chungnam and Gyungnam provinces were different. Comparing the average length of English diphthongs of Korean collegians with those of American natives, we can see that native English speakers tend to pronounce the English diphthongs shorter than Korean collegians do. However, native English speakers tend to pronounce the English low vowels longer than Korean collegians do. In this study we also tried to find out the differences of English diphthongs and low vowel lengths in relation to their utterance positions among American natives and Chungnam and Gyungnam dialect speakers. By the results of this experiment, we observed a lengthening effect in the three groups. However, in the pronunciation of American natives, a lengthening effect of English vowels was more clearly observed, especially in the pronunciation of English diphthongs.

Computer-Assisted Pronunciation Training system is considered to be a useful tool for pronunciation learning for students who received elementary level English pronunciation education, especially for students who have difficulty in correcting their pronunciation in front of others or who are not able to receive face-to-face training. The conventional Computer-Assisted Pronunciation Training system shows the word to the user, the user pronounces the word, and then the system provides phoneme or audio feedback according to the pronunciation of the user. In this paper, we propose a Computer-Assisted Pronunciation Training system that can practice on the varying pronunciation according to positions of adjacent phonemes. To achieve this, the proposed system is implemented by recommending a series of words by focusing on adjacent phonemes for simplicity and clarity. Experimental results showed that word recommendation considering adjacent phonemes leads to improvement of pronunciation accuracy.

The purpose of this study is to compare the first two vowel formants of the stressed and unstressed English vowels produced by ten young males (in their twenties and thirties) and ten old males (in their forties or fifties) from the Buckeye Corpus of Conversational Speech. The results indicate that the stressed and unstressed vowels, /i/ and $/{\ae}/$ in particular, from the two groups are different in their formant frequencies. In addition, the vowel space of the unstressed vowels is somewhat smaller than that of the stressed vowels. Specifically, the range of the second formant of the unstressed vowels and that of the first formant of the unstressed front vowels were compressed. The findings from this study can be applied to the pronunciation training for the Korean learners of English vowels. We propose that teachers of English pay attention to the stress patterns of English vowels as well as their formant frequencies.

Koreans and English have different phonotactic constraints and phonological rules. It causes Korean learners to have difficulty in pronouncing certain English consonant clusters correctly. This paper aims to discuss what English consonant clusters are difficult for Korean learners to learn and why this difficulty arises by comparing phonotactic constraints and phonological rules of English and Korean.

Pronunciation teaching is once again coming into the foreground of ELT. Japan is, however, lagging far behind many countries in the development of pronunciation curricula and in the actual speech performance of the Japanese learners of English. The reasons for this can be found in the prevalence of communicative methodologies unfavorable for pronunciation teaching, in the lack of trained professionals, and in the large numbers of students in Japanese foreign language classes. This paper offers a way to promote foreign language pronunciation teaching in Japan and other countries by means of employing computer and internet facilities. The paper outlines the major directions of using modem speech technologies in pronunciation classes, like EVF (electronic visual feedback) training at segmental and prosodic levels; automated error detection, testing, grading and fluency assessment. The author discusses the applicability of some specific software packages (CSLU, SUGIspeech, Multispeech, Wavesurfer, etc.) for the needs of pronunciation teaching. Finally, the author talks about the globalization of pronunciation education via internet resources, such as computer corpora and speech and pronunciation training related web pages.
