In this paper, we examine the allophones of an underlying segment /l/ in Korean dialects. In particular, we examine how an underlying /l/ sound surfaces in the Korean dialect spoken at Yonbyon, China. To do so, we employ the following processes: First, we perform the phonetic studies on the allophones of an underlying /l/ in the Yonbyon dialect. Secondly, we compare the phonological environments of the allophones of an underlying /l/ in the Yonbyon dialect with the South Korean dialect. Finally, we discuss the phonological implications of the allophones of the underlying /l/ in terms of Feature Geometry and Syllable Contact Law. Based on the phonetic study, we will argue that the distinctive feature [sonorant] should be placed outside the root node and that the flap, an allophone of an underlying /l/, should be understood as an obstruent, not a sonorant.

This study, as a successive study of Ko(1998a) which investigates the effect of vowel length contrast on the voicing of the word-final consonants in English, examines if other phonetic features of word-final stops themselves affect the Perception of their voicing. They are closure duration, voicing status during closure period, release portion. 68 Korean students learning English as a second language in Wonkwang University participate as subjects for this study. The results showed that they are not important clues to Korean students to the voicing identification of the word-final stops in English.

To improve the performance of automatic labelling system, the context-dependent demiphone unit was proposed. A phone is divided into two parts: a left demiphone that accounts for the left side coarticulation and a right demiphone that copes with the right side context. Demiphone unit provides a better training of the transition between phones. In this paper, If the length of the phone is less than 120 msec, it is split into two demiphones. If the length of the phone is greater than 120 msec, it is divided into three parts. In order to evaluate the performance of the system, we use 452 phonetically balanced words(PBW) database for training and testing phoneme models. According to the experiment, the system using proposed demiphone unit compared with that using old demiphone unit gains 3.83% improved result(71.63%) within 10ms of the duo boundary, and 2.20% improved result(86.41%) within 20ms of the true boundary.

The Purpose of this paper is to gather pairs of heteronyms in modern Korean and transcribe them in the IPA and the Roman alphabet in order to propose that all of them should be differentiated in Hanngul orthography. More than a quarter of the whole Korean vocabulary consists of words with a long vowel and the number of minimal pairs distinguished only by the chroneme reaches nearly ten thousand (i.e. twenty thousand words). The letter h syllable-finally is used here to represent the long vowel in Romanization except the vowel '으‘[?:] which is transcribed by doubling the letter u (i.e. uu). Another factor bringing forth lots of heteronyms in Korean is the lack of full indication as to the non-automatic reinforcement in the initial consonant of a word (or a morpheme) when preceded by another within a phrase (or a word). These reinforced word-initial consonants are written with the letter c and an apostrophe (like c'g- , c'd- , c'b-, c's-, c'j-) in Romanization here. The reinforced morpheme-initial consonant within a word is written with the letters k t, p, ss and cz for ㄲ, ㄸ, ㅃ, ㅆ and ㅉ sounds respectively. The contrasted pronunciations of pairs of heteronyms beginning with ㅅ /s/sup h// and ㅆ /s/ sounds are transcribed here for exemplification.

The prosodic characteristics of Korean particles in read speech were examined in this paper based on K-ToBI labeling system in order to see whether they are prosodically weak form like functions words in English. Acoustic measurements and statistical analysis were done focusing on the distribution of particles over a variety of prosodic positions, prosodic positional effects on the phonetic realization of particles, and acoustic strength of particles compared to those of their surrounding syllables. The panicles were distributed rather equally over all 4 prosodic positions with the highest frequency at IP-medial/AP-final position and the lowest at IP-medial/AP-medial position except that topic marker 'Un/nUn' showed preference for IP-final/AP-final position. There was a significant prosodic positional effect on the duration and F0 of the particles. Duration was the longest at IP-final/AP-final position and interestingly, at IP-medial/AP-medial position while F0 was the highest at IP-final/AP-medial Position as expected. The comparison of the acoustic properties of the particles with those of neighbor syllables showed that duration was generally significantly longer and energy also showed larger values, if not significant, in particles suggesting that the particles in Korean are not prosodically weaker like function words in English.

본 논문은 한국인과 일본인이 영어 유음 /l/과 /r/을 발음하는데 있어서 어떤 요소들이 가장 큰 영향을 미치는가를 알아보는데 중점을 두고 있다. Park & Ingram (1995)에서는 한국인과 일본인의 영어 발음인지(perception) 실험을 통해 동 문제에 대해 분석을 해보았는데 본 논문에서는 같은 주제를 발음 실험을 통해 그 해답을 찾고 있다. 실험의 결과는 언어 의존적인 요소인 모국어 음운 체계의 영향뿐만 아니라 언어 독립적인 요소인 화자(speaker), 유음이 나타나는 위치(position), 유음의 유형(type) 그리고 영어 유음을 발음하는 각 개인 등의 요소들이 모두 한국인과 일본인의 영어 유음 /l/과 /r/ 발음에 영향을 미치고 있음을 보여 주고 있다. 이는 인지 실험에서도 드러난 바로 인지와 발음은 서로 밀접한 관계를 맺고 기제가 일어나고 있음을 보여 준다.

이 논문의 목적은 일본 학생들의 영어 청취 능력에 대한 확실한 평가를 내릴 수 있는 청취판별테스트를 개발하는 데에 있다. 이 테스트를 통하여 일본사람들이 범하는 청취 오류를 평가, 분석하고 일본어의 음성·음운체계가 이러한 오류에 미치는 영향을 평가한다. 테스트의 결과는 청취 및 발음훈련에 적용될 수 있으므로 일본인의 영어 능력을 향상시키는데 공헌할 수 있을 것이다.
