The purpose of this paper is to show how the coda of a syllable and word-final clusters are represented in the English syllable structure. Previous theories on the syllable assume that there is only one segment in the coda position. And, as we know, the theories that license only one segment in the coda make it difficult to syllabicate the word-final cluster appropriately when more than two segments in the word-final cluster are encountered. I considered three approaches: the previous syllable structure (Selkirk, 1982; Borowsky 1989), sonority sequencing (Giegerich, 1992; Roca, 1999) and feature analysis (Goldsmith, 1990), But, all the considered methods don't give us a satisfactory explanation regarding word-final clusters. Finally, I will suggest a modified syllable representation as an alternative by placing two different appendixes under the Phonological Word which forms a constituent above the syllable node. From this it is possible to explain the former problematic word-final clusters including morphological information asan inflectional suffix in the structure.

This experimental study shows that, in reading of the English isolated words that are enumerated, the releasing of the word-final stop is employed for signaling enumeration in company with the well-known intonational pattern for it. Furthermore, this study tries to find the aspects of the releasing of the stops in the word-final positions, focusing on the association of the stop releasing/nonreleasing with i) the POA (Place of Articulation) distinction of the word-final stop, ii) the various qualities of the vowel before the final stop, and iii) the voice distinction of the stop in the word-final position.

The purposes of this study are (1) to investigate the correlation between English word-final stop and the duration of vowels before word-final stop and (2) to suggest a way to detect pronunciation errors and teach the pronunciation of English word-final stops. For these purposes, 18 Korean speakers' production was recorded and analysed using Speech Analyzer and their production was compared with that of native English speakers. In addition, two native English speakers evaluated the subjects' pronunciation. The major findings are the voicing dependent effect of the English vowels produced by native Korean speakers is lower than that of native English speakers; Korean speakers release English word-final stops less than native English speakers; and the pronunciation of English word-final stops and the duration of adjacent vowels are closely related in that the pronunciation score of final stops and the ratio of vowels between the vowels before voiced stops and voiceless stops are correlated. In addition, this study concludes with pedagogical suggestions that may be useful for English pronunciation teaching.

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.

본 연구는 영어에서 어말 자음의 유무성성에 따라 선행하는 모음의 길이에 차이가 나타나는 현상이 어말 자음, (부분) 무성음화 정도, 폐쇄음의 파열 여부와 가지는 상관관계에 대해서 살펴보고자 한다. 또한, 선행 모음의 길이 차이에 대한 여러 설명 중 무성 자음 앞 모음보다 유성 자음 앞 모음을 더 길게 발화하여 어말 자음의 유무성성을 구별한다는 기능적인 관점을 중심으로 연구 결과를 보고자 한다. 본 연구는 영어 원어민 화자들을 대상으로 발화 실험을 진행하고 선행하는 모음의 길이, 어말 유성 자음의 (부분) 무성음화 정도, 어말 폐쇄음의 파열 유무를 측정하였다. 발화 실험 결과, 어말 자음의 유무성성에 따른 선행 모음 길이 차이의 비율은 어말 자음이 폐쇄음인지, 마찰음인지에 따라 달라지지 않았다. 또한, 어말 유성 자음의 (부분) 무성음화 정도가 크게 나타날수록 어말 유성 자음 앞 모음의 길이가 길게 나타나며 기능적 관점에서 예측한 바와 일치하는 결과가 나타났다. 마지막으로, 기능적 관점에 따른 예측과는 다르게 선행 모음 길이 차이의 비율은 어말 폐쇄음이 파열 없이 발화되었을 때보다 파열하여 발화되었을 때 더 크게 나타났다. 이러한 결과는 어말 자음의 유무성성에 따른 선행 모음 발화 길이의 차이를 기능적 관점으로만 설명하기에는 한계가 있다는 것을 시사한다.

This study aims at examining the relationship between tonal events and their related vowel and syllable duration in Korean. Two things were investigated: one is to see if there is a hierarchical relationship in prosodic unit-final-lengthening and the other is to see if accentual phrase initial high tone syllable gets lengthened. Generally, higher prosodic units show larger degree of lengthening of the final vowel and also final syllable duration than the lower ones except for accentual phrase: Mean duration of utterance-final or intonational-phrase-final syllable(and its vowels) was longer than that of accentual-phrase-final or word-final syllable(and its vowels). However, mean duration of accentual phrase final syllable was shorter than that of word final syllable. Mean vowel duration of accentual phrase initial high tone syllable was shorter than that of any other prosodic unit. Its mean syllable duration, however, was longer than that of accentual-phrase-final or word-final syllable, indicating that strong consonants(fortis and aspirated) frequently appear in the accentual phrase initial position and this position is a prosodically strong position showing longer duration as well as high tone.

This study investigated final consonant error characteristics at word-medial position in children with functional articulation disorder. Data was collected from 11 children with functional articulation and 11 normal children, ages 4 to 5. The speech samples were collected from a naming test. Seventy-five words with every possible bi-consonants matrix at the word-medial position were used. The results of this study were as follows : First, percentage of correct word-medial final consonants of functional articulation disorder was lower than normal children. Second, there were significant differences between two groups in omission, substitution and assimilation error. Children with functional articulation disorder showed a high frequency of omission and regressive assimilation error, especially alveolarization in regressive assimilation error most. However, normal children showed a high frequency of regressive assimilation error, especially bilabialization in regressive assimilation error most. Finally, the results of error analysis according to articulation manner, articulation place and phonation type of consonants of initial consonant at word-medial, both functional articulation disorder and normal children showed a high error rate in stop sound-stop sound condition. The error rate of final consonant at word-medial position was high when initial consonant at word-medial position was alveolar sound and alveopalatal sound. Futhermore, when initial sounds were fortis and aspirated sounds, more errors occurred than linis sound was initial sound. The results of this study provided practical error characteristics of final consonant at word-medial position in children with speech sound disorder.

The Korean high back vowels /o/ and /u/ have been reported to be in a state of near-merger especially among young female speakers. Along with cross-generational changes, the vowel position within a word has been reported to render different phonetic realization. The current study examines native English speakers' ability to attend to the phonetic cues that distinguish the two merging vowels and the positional effects (word-initial vs. word-final) on the identification accuracy. 28 two-syllable words containing /o/ or /u/ in either initial or final position were produced by native female Korean speakers. The CV part of each target word were excised and presented to six native English speakers. The results showed that although the identification accuracy was the lowest for /o/ in word- final position (41%), it increased up to 80% in word-initial position. The acoustic analyses of the target vowels showed that /o/ and /u/ were differentiated on the height dimension only in word-initial position, suggesting that English speakers may have perceived the distinctive F1 difference retained in the prominent position.

The purpose of this study was to investigate the phonological error patterns of korean children with and without specific phonological disorders(SPD). In this study, 29 normally developing children and 10 SPD children were involved. The children were matched the percentage of consonants correct(PCC). 22 picture cards were used to elicit korean consonants in word initial syllable initial, word medial syllable initial, word medial syllable final, word final syllable final positions. The findings were as follows. First, the phonological error patterns of SPD were 1) similar to those of normal children with the same PCC, 2) similar to those of normal children with the lower PCC, or 3) unusual to those of normal children. Second,. korean children showed phonological processes reflecting the korean phonological characteristics: tensification, reduction of the word medial syllable final consonant. This study suggests that both the PCC and error patterns should be considered in assessing phonological abilities of children.
