The intent of the present study is to investigate the acoustic properties of Korean /w/ in various phonological contexts, compare them with those of English /w/, and attempt to explain why English /w/'s are perceived differently by Korean speakers depending on the phonological contexts. Experiments 1 and 2 present the acoustic measure of F2 of Korean /w/ in various linguistic positions and show that unlike English /w/, Korean /w/ shows quite a strong coarticulation with the following vowel. Based on these experiments, Experiment 3 investigates why English /w/ is adapted differently into Korean. Specifically, it discusses why English /wain/ is adapted as /wain/ whereas English /twin/ is adapted into Korean as $/t^{h_i}win/$ with an extra vowel. This study argues that the different perception of English /w/ by Korean and English speakers is due to the different F2 transitional pattern of /w/ in Korean and English in various phonological contexts. It also argues that the F2 transitional pattern is an important factor in the perception of /w/.

The aim of this study is to find out how the labiovelar onglide /w/ in English kwV sequences that have minimal pairs with kV sequences is pronounced differently among Korean EFL learners based on acoustic evidence. This study tries to identify /w/ sound in English kwV sequences through spectrograms and to examine the duration ratios of each segment in kwV words to compare the patterns of an English native speaker with those of Korean speakers of English. In spectrographic analyses, the complete deletion of /w/ and partial pronunciation of /w/ dubbed [$k^{w}$] were identified as well as the targetappropriate production of /w/. The general production patterns with respect to the duration ratios in English [kw] sequence words showed that the subjects who produced /w/ had similar ratio patterns that the native speaker had in that the vowel duration ratio in kwV sequences was shorter than that in kV sequences. By contrast, the subjects who deleted [w] had a long ratio of the onset [$k^{h}$] while the speaker with a partial pronunciation of /w/ had a long ratio of the following vowel.

This study concerns the constraints of English Poetic Meter. In English poems, the metrical pattern doesn't always match the linguistic stress on the lines. These mismatches are found differently among the poets. For the lexical stress mismatched with the weak metrical position, W⇒ Strength is established by the concept of the strong syllable. The peaks of monosyllabic words mismatched with the weak metrical position are divided according to which side of the boundary of a phonological domain they are adjacent to. Adjacency Constraint I is suggested for the mismatched peak which is adjacent to the left boundary of a phonological domain; /sup */Peak] and Adjacency ConstraintⅡ for the mismatched peak which is adjacent to the right boundary of a phonological domain. These constraints are various according to the poets (Pope, Milton and Shakespeare) : /sup */[Peak [-stress], /sup */W⇒ Strength and /sup */Peak] in Pope; /sup */[+stress][Peak[-stress] and /sup */Peak] in Milton; /sup */[ +stress][Peak[-stress], /sup */W⇒Strength and Adjacency ConstraintⅡ in Shakespeare.

This paper aimed at examining the influence of L1 (native language) phonology when speakers of L1 perceive L2 (foreign language) sounds. Korean and Japanese learners of English took a perception test of Australian English words 'work', 'walk' and 'wok'. Based on Korean and Japanese phonology, it was predicted that Korean subjects would face more difficulties than Japanese subjects. The results of the experiment substantiated the influence of L1 phonology in L2 learners' L2 sound perception.

This study analyzes Korean high school students' pronunciation errors in word-initial onglides in English. For this study, 24 Korean high school students read 34 English words including glide-vowel sequences in word-initial positions and vowel-initial words in a frame sentence. The results showed 2 different error types: glide deletion and vowel distortion. After the analysis of the first recording, the subjects were taught how to pronounce glide-vowel sequences properly in a 60-minute class. Comparison of the analyses of the first and second recordings showed that the subjects improved on the pronunciation of glide-vowel sequences. After the training, the pronunciation errors of diphthongs unique to English, [$j_I$], decreased substantially. However, most subjects still had difficulties in pronouncing [$w{\mho}$], [wu], and [wo]. There was no significant correlation between English course grade and error reduction.

본 연구는 최소짝을 이용하여 한국인 피 실험자들의 영어자모음과 반모음의 음소구별능력을 살펴본 실험적 연구이다. 음소구별능력을 알아보는 실험의 방법으로는 청해시험을 활용하였으며, 거기에서 얻어진 결과를 통해 다음의 세 가지를 확인할 수 있었다. 첫째, 피 실험자들이 영어자음음소의 구별에 비해 영어모음음소의 구별에 상대적인 어려움을 겪고 있다는 점이다. 둘째, 영어모음음소 중에서도/ə:/와 /ɔ:/의 구별에 심각한 어려움을 겪고 있음을 확인할 수 있었다. 셋째로, 반모음/w/음의 유무에 따른 구별능력에서는 피 실험자 전원이 어려움 없이 구별해내고 있었는데, 이는 반모음/w/의 유무를 단어의 발음에서 쉽게 구별하고 있음을 보여주는 증거이다. 이러한 실험의 데이터 분석을 시각화함으로써 실험결과를 영어교육현장에서 활용할 수 있도록 스펙트로그램의 그림분석을 병행하였다.

호주 영어의 단어 중 한국인과 일본인이 구별하기 어려운 'work', 'walk', 'wok' 세 단어에 대해 다룬다. 우선 한국인과 일본인이 이들 세 단어를 어떻게 조음할 것인가를 예측하고, 실제로 한국인과 일본인 화자들이 조음한 자료를 가지고 모듬의 음질과 길이 두가지 측면으로 나누어 예측한 사항과 비교하고 또 이들 단어를 조음할 때 한국인과 일본인 사이에 어떤 음성 음운적 특징이 나타나는지도 비교 분석한다. 결과는 모국어의 음성, 음운적 영향이 목표어의 음소를 습득하고 발음하는데에 영향을 미친다는 사실을 보여주고 있다. 하지만 wok/wo k/의 예는 언어 보편적인 요소가 L2의 음소를 습득하는데 있어 또 하나의 요소로 작용하고 있음도 알려주고 있다.

The aim of this paper is to analyse difficulties of the pronunciation in swedish vowels encountered by Koreans learners and to seek solutions in order to correct the possible errors. In the course of the analysis the swedish and Korean vowels in question are compared with the purpose of describing differences aha similarities between these two systems. This contrastive description is largely based on the students' articulatory speech level ana the writer's auditory , judgement . The following points are discussed : 1 ) Vowel length as a distinctive feature in Swedish compared with that of Korean. 2) A special attention is paid on the Swedish vowel [w:] that is characterized by its peculiar type of lip rounding. 3) The six pairs of Swedish vowels that are phonologically contrastive but difficult for Koreans to distinguish one from the other: [y:] ~ [w:], [i:] ~ [y:], [e:] ~ [${\phi}$:], [w;] ~ [u:] [w:] ~ [$\theta$], [$\theta$] ~ [u] 4) The r-colored vowel in the case of the postvocalic /r/ that is very common in American English is not allowed in English sound sequences. The r-colored vowel in the American English pattern has to be broken up and replaced hi-segmental vowel-consonant sequences . Korean accustomed to the American pronunciation are warned in this respect. For a more distinct articulation of the postvocalic /r/ trill [r] is preferred to fricative [z]. 5) The front vowels [e, $\varepsilon, {\;}{\phi}$) become opener variants (${\ae}, {\;}:{\ae}$] before / r / or supradentals. The results of the analysis show that difficulties of the pronunciation of the target language (Swedish) are mostly due to the interference from the Learner's source language (Korean). However, the Learner sometimes tends to get interference also from the other foreign language with which he or she is already familiar when he or she finds in that language more similarity to the target language than in his or her own mother tongue. Hence this foreign language (American English) in this case functions as a second language for Koreans in Learning Swedish.
