In this paper English word-final /s/ and /z/ produced by English and Korean speakers were investigated. The durations and maximum intensities of these fricatives with those of their preceding vowels were compared. In the English speakers' productions, they relied on the ratio of the durations of them as well as the ratio of the maximum intensities of them. In their productions, the /s/ was long in duration and high in maximum intensity and its preceding vowel was short in duration whereas the /z/ was short in duration and low in maximum intensity and its preceding vowel was long in duration. However, the maximum intensities of the preceding vowels were not different in their productions. But in the Korean speakers' productions, they relied on neither the ratio of the durations of them nor the ratio of the maximum intensities of them. In their productions, the /s/ and the /z/ were not different in durations, but the duration of the preceding vowel of the /s/ was shorter than that of /z/, and the maximum intensities of the /s/ and /z/ as well as their preceding vowels were not different. Based on these results we can conclude that in distinguishing /CVs/ and /CVz/ words, English speakers used durations and intensities of the word-final fricatives in addition to durations of the vowels whereas Koreans used only durations of the vowels.

Although Korean university students' primary concern is academic success in their higher degrees in the UK, they highly desire to develop English communicative competence through a number of opportunities to speak with natives speakers. The paper aims at examining to what extent they are able to be socialised into a new environment while they are studying at UK universities. The in-depth, longitudinal interviews with the targeted group of six Korean masters' students at the University of York was undertaken to observe the pace of their progress in developing social skills. Reluctance and hesitance to contact and interact with their supervisors and other academic staff persisted for most of them to the final term caused by cultural reasons such as face and hierarchy rather than language problems. Despite the six participants' variation in their patterns of social interaction, they struggled with pressures towards monoculture-biased interaction with Korean people, which was quite extreme for the five participants. This passivity can be explained by several reasons such as the students' lack of communicative competence and other situational factors on one-year course. It is important to note that students' failure to develop network with native speakers is strongly associated with experience of cultural withdrawal and frustration with developing communicative competence in English.

This study compared the relative contributions of intensity, F0, duration and vowel spectra of L2 English lexical stress by Japanese and Korean learners of English. Recordings of Japanese, Korean and native English speakers reading eighteen 2 to 4 syllable words in a carrier sentence were analyzed using multiple regression to investigate the influence of each acoustic correlate in determining whether a vowel was stressed. The relative contribution of each correlate was calculated by converting the coefficients to percentages. The Japanese learner group showed phonological transfer of L1 phonology to L2 lexical prosody and relied mostly on F0 and duration in manifesting L2 English stress. This is consistent with the results of the previous studies. However, advanced Japanese speakers in the group showed less reliance on F0, and more use of intensity, which is another parameter used in native English stress accents. On the other hand, there was little influence of F0 on L2 English stress by the Korean learners, probably due to the transfer of the Korean intonation pattern to L2 English prosody. Hence, this study shows that L1 transfer happens at the prosodic level for Japanese learners of English and at the intonational level for Korean learners.

This study aims to investigate the rhythmic patterns in the English speech produced by Chinese learners of English who learn English as a foreign language (EFL learners). Utilizing interval-based rhythm metrics, namely, VarcoC, VarcoV, nPVI-C, nPVI-V, and %V, the study compared the rhythmic differences in English speech between ten native speakers from the United States and forty Chinese EFL learners from mainland China. A sentence elicitation task consisting of thirty picture prompts and corresponding thirty stimuli sentences with at least five vocalic and four consonantal intervals was conducted. Statistical results reveal that both Chinese advanced learners and beginners had significantly lower degree of stress-timed in their English speech, indicating that the acquisition of the L2 speech rhythm was influenced by the learners' L1 rhythmic pattern. In addition, the results also show that the Chinese advanced learners had significantly higher degree of stress-timed in their English speech than beginners and showed no significant difference with native speakers in VarcoC and nPVI-C. These results indicate that the direction of L2 speech rhythm development was from more syllable-timed to more stress-timed.

The phonetic mastery of English has been considered next to impossible to many non-native speakers of English, including even some teachers of English. This paper takes issue with this phonetic problem of second language acquisition and proposes that combination of cognitive and physical approaches can help master English faster and more easily.

This study explored the discrimination of synthesized English vowel pairs by twenty-seven American and Korean, male and female listeners. The average formant values of nine monophthongs produced by ten American English male speakers were employed to synthesize the vowels. Then, subjects were instructed explicitly to respond to AX discrimination tasks in which the standard vowel was followed by another one with the increment or decrement of the original formant values. The highest and lowest formant values of the same vowel quality were collected and compared to examine patterns of vowel discrimination. Results showed that the American and Korean groups discriminated the vowel pairs almost identically and their center formant frequency values of the high and low boundary fell almost exactly on those of the standards. In addition, the acceptable range of the same vowel quality was similar among the language and gender groups. The acceptable thresholds of each vowel formed oval to maintain perceptual contrast from adjacent vowels. The results suggested that nonnative speakers with high English proficiency could match native speakers' performance in discriminating vowel pairs with a shorter inter-stimulus interval. Pedagogical implications of those findings are discussed.

This research examines Japanese non-native speakers' (JNNS) modal auxiliary verb use from two different perspectives: frequency of use and preferences for modalities. Additionally, error analysis is carried out to identify errors in modal use common among JNNSs. Their modal use is compared to that of English native speakers within a spoken dialogue corpus which is part of the International Corpus Network of Asian Learners' English. Research findings show at a statistically significant level that when compared to native speakers, JNNSs underuse past forms of modals and infrequently convey epistemic modality, indicating the possibility that JNNSs fail to express their opinions or thoughts indirectly when needed or to convey politeness appropriately. Error analysis identifies the following three types of common errors: (1) the use of incorrect tenses of modal verb phrases, (2) the use of inflected verb forms after modals, and (3) the non-use of main verbs after modals. The first type of error is largely because JNNSs do not master how to express past meanings of modals. The second and third types of errors seem to be due to first language transfer into second language acquisition and JNNSs' overgeneralization of the subject-verb agreement rules to modals respectively.

This paper examines the pragmatic features of the thanking and apologizing moves which appear in requestive email of Korean speakers of English as a foreign language and American English native speakers. It is important for second language learners to behave appropriately in a target language when communicating with other English speakers who have different cultural backgrounds. The result of this study revealed the differences in the use of thanking and apologizing moves in the requestive email between Koreans and Americans. Koreans used fewer moves of thanking and more moves of apologizing than Americans in three different situations. Koreans' underuse of thanking which is a routine and formulaic expression for Americans could be a marked phenomenon to a recipient of the email in English bringing about a minus effect.

This study investigated the influences of probabilistic accessibility of the word being produced - as determined by its usage frequency and neighborhood density - on native and high-proficiency L2 speakers' realization of six English monophthong vowels. The native group hyperarticulated the vowels over an expanded acoustic space when the vowel occurred in words with low frequency and high density, supporting the claim that vowel forms are modified in accordance with the probabilistic accessibility of words. However, temporal expansion occurred in words with greater accessibility (i.e., with high frequency and low density) as an effect of low phonotactic probability in low-density words, particularly in attended speech. This suggests that temporal modification in the opposite direction may be part of the phonetic characteristics that are enhanced in communicatively driven focus realization. Conversely, none of these spectral and temporal patterns were found in the L2 group, thereby indicating that even the high-proficiency L2 speakers may not have developed experience-based sensitivity to the modulation of sub-categorical phonetic details indexed with word-level probabilistic information. The results are discussed with respect to how phonological representations are shaped in a word-specific manner for the sake of communicatively driven lexical intelligibility, and what factors may contribute to the lack of native-like sensitivity in L2 speech.
