This experimental study has a goal to explore the perceptual sensitivity to phonetic evidence such as duration, phrase accent, or pause in disambiguation. We argue that the realization of the intonational phrasal boundary at the meaningful grammatical boundary in structurally ambiguous sentences facilitates English native listeners to distinguish the meanings of the ambiguous sentences. Moreover, the duration of the phrase-final syllable, pitch range reset, or phrasal tones also provides listeners with important phonetic evidence in disambiguation. In our perception experiment, however, Korean English learners largely depend on the realization of pause. In the results from the perception experiment, all of the groups showed an increase in the response time from the perception of no pause to pause realization. This means that pause at the phonological phrasal boundary plays a role of facilitator to English native speakers with other prosodic cues such as duration, pitch accent, or phrasal tones, while an absolutely important cue to Korean English learners.

Korean (L1)-English (L2) bilingual adults' and children's production of Korean and English stops was examined to determine the age effects and L2 experience on the development of L1 and L2 stop contrasts. Four groups of Seoul Korean speakers (experienced and inexperienced adult and child groups) and two groups of age-matched native English speakers participated. The overall results of voice onset time (VOT) and fundamental frequency (F0) of phrase-initial stops in Korean and word-intial stops in English showed a delay in the acquisition of L1 due to the dominant exposure to L2. Significantly longer VOT and lower F0 for aspirated stops as well as high temporal variability across repetitions of lenis stops were interpreted to indicate a strong effect of English on Korean stop contrasts for bilingual children. That is, the heavy use of VOT for Korean stop contrasts shows bilingual children's attention to the acoustic cue that are primarily employed in the dominant L2. Furthermore, inexperienced children, but not adults, were shown to create new L2 categories that are distinctive from the L1 within 6 months of L2 experience, suggesting greater independence between the two phonological systems. The implications of bilinguals' age at the time of testing to the degree and direction of L1-L2 interaction are further discussed.

This paper reports the results of an experimental phonetic study of intonation contrasts perception by speakers of British English, Japanese and Russian. Six series of re-synthesized two-syllable rise-fall contours with manipulated parameters of the rise in the first and the fall in the second syllable were employed in the experiment. Modifications of pitch height were executed in 2 st steps, and of duration - in 30ms steps. The subjects, who were native speakers of British English, Japanese and Russian, identified the sentence type of presented re-synthesized stimuli. The results of the experiments demonstrate overall similarity of the perception strategies across the three groups of subjects, especially regarding the thresholds of 'declarative' sentence type judgement. Non-declarative judgements are more language-specific. The results can be employed for the teaching of English, Japanese and Russian as foreign languages as well as for speech synthesis and recognition.

We investigate whether the word frequency effects occur in native speakers' homophone speech in such a way that less frequent words are produced with greater magnitudes in duration and F0 than more frequent words. Acoustic analyses of homophone data produced by four speakers reveal that there is a tendency that vowels in less frequent words get longer than those in more frequent words, and statistical tests verify the significance of their differences. On the other hand, no considerable correlation has been discovered between F0 and word frequency.

영어 강세는 발화된 영어 단어를 이해하는 데 상당히 중요한 역할을 하며 잘못된 강세의 위치는 의사소통의 실패로 이어질 수 있다. 강세가 없는 것으로 알려진 한국어를 모국어로 둔 영어 학습자는 영어 운율체계를 습득하는 데 어려움을 겪을 것으로 예상된다. 본 연구는 한국어가 단어 수준에서 이러한 강세를 실현하는 것이 영어와 어떻게 다른지 그리고 한국인 영어 학습자의 중간언어가 이 두 언어와 어떻게 다른지 연구하였다. 다음 절로 이루어진 4개의 영어 외래어와 그들의 영어 원어 4개가 실험단어로 사용되었다. 10명의 영어 원어민이 영어 원어를 읽었으며 10명의 한국인 영어 학습자가 먼저 영어 외래어를 한국어로 그리고 나중에는 영어 원어를 영어로 읽었다. 120개의 발화 샘플을 분석한 결과 한국어에는 모든 강세 자질로 (즉, 조음 길이, 조음 크기, 조음의 높이) 실현되는 두드러진 음절이 없었다. 반면에 영어는 모든 강세 자질에 의해 일관되게 실현되는 상대적으로 두드러진 음절을 가지고 있었다. 흥미롭게도 영어 강세 실현에 있어 한국인 영어 학습자의 중간언어는 모국어보다도 영어와 비슷한 특징을 보여 주었다.

영어 마찰음을 발음하기 어려운 점은 잘 알려졌는데, 한국 대학생들이 마찰음을 포함하는 영어 순자음을 인지하는데도 마찬가지로 어려움을 느끼는지 알아보기 위하여 40명의 한국 대학생들을 대상으로 영어 순자음이 들어간 임시어를 4가지 다른 운율적 위치(초성, 종성, 강세 앞 모음사이, 강세 뒤 모음사이)에서 인지하는 테스트를 실행하였다. 실험 참가자들은 초성이나 강세 앞 모음사이처럼 강한 위치의 자음을 종성이나 강세 뒤 모음사이의 약한 위치보다 더 정확하게 판별하는 인지패턴을 보여주었다. 한국 학생들의 인지의 어려움은 모든 운율 위치에서 영어 목표자음의 조음방법 혼동 때문에 대부분 발생하였다. 그밖에, 조음장소와 유무성의 혼동도 일어났는데, 조음장소의 혼동은 모든 운율 위치에서 주로 [f]의 음향적 속성 때문에 일어났으며 유무성의 혼동은 운율 위치의 영향 때문에 발생하였다. 이러한 조음방법, 조음장소, 유무성의 혼동은 목표자음의 음성적 속성 그리고/또는 피실험자의 모국어 속성으로 설명되었다.

Twenty five English native speakers with two different L2 experienced groups and nineteen native Koreans heard both Korean word-initial nasals (/m/ and /n/) in three vowel contexts (low, mid, and high) produced by a native Korean speaker. The experiment examined the hypothesis that Korean nasals are more likely to be judged or perceived correctly by the L2-experienced English learners of Korean than the unexperienced counterparts. The result showed that L2 experienced group was more sensitive to effects of vowel height in judging the Korean nasals in which the perception of nasals before the high vowels was more subject to it. In addition, place of nasal articulation causes asymmetry relations - bilabial nasal /m/ is more likely to be perceived as plosives rather than alveolar nasal /n/. The study found that the L2 experience has a somewhat limited role in perceiving the nasals correctly in the word-initial position, especially before the high vowels, in that even the L2 experienced English subjects have difficulty in identifying the Korean nasals correctly in this environment. Nevertheless, low L2 proficiency might be accounted for the difficulty in the bilabial nasal identification observed by the L2 experienced group.

This study explores the study experiences of Southeast Asian students at a reputable Korean private university in Seoul. In particular, this study focuses on difficulties and coping strategies of both non-native speaker of English and native-speakers of English who are working for their undergraduate or postgraduate degrees. Interviews of fourteen students from five Southeast Asian countries were collected and analyzed by NVivo 9. Thematic analysis result shows that many students, particularly non-native speakers of English, had much more difficulties than their counterparts, in contemporary Korean university context, where internationalization indices-driven strategies including expanding courses conducted in English language. Also, this study observes and documents contrasting patterns of different degree of difficulties experienced by students, depending on their degree levels and majors. Undergraduate students in science and engineering majors had the greatest degree of difficulties among all. In contrast, their graduate counterparts seem to have less difficulties. This might be related to the fact that graduate students in science and engineering majors are mostly working with their peers in their own labs, which provides institutional support. Coping strategies of students show that international students, facing unfavorable or unfriendly treatments by their Korean peers, developed innovative strategies, including using the internet technology to catch up with the classes that they could not fully understand. As a whole, adaptation process of international students do not seem to be passive or one-way. This study also provides policy implications for international students, particularly, who can be categorized as linguistic and ethnic minorities.

The present study investigated Korean learners' knowledge on the range of possible interpretations of English locative PPs with manner of motion verbs, and considers whether learners can arrive at a superset L2 grammar on the basis of positive L2 input. Unlike Korean, some English locative PPs occurring with manner of motion verbs (such as in John jumped on the bed) are ambiguous as they can be interpreted as either directional or locational. Thirty Korean learners of English in three distinct groups (Advanced EFL-only group; Intermediate-EFL-only group; and ESL-experienced group) participated in an experimental study, along with a control group of nine native speakers of English. The results of the study showed that I) Korean learners, overall, tended to interpret English locative PPs as only locational, failing to recognize the ambiguity between the directional and locational readings in the target structure; 2) For the learners who experienced only the EFL context, even highly proficient learners, as well as intermediate level learners, failed to acknowledge the ambiguity; 3) The learners who experienced the ESL context for an extended period of time could identify the target reading to some extent, although they still could not reach the native-like competence. From these results, it is argued that robustness of positive evidence, not simply its availability, is critical in the acquisition of the superset L2 targets like the present one.
