This paper aims to contrast phonology of Korean and Thai in terms of language universality. Considering consonants, both languages having 21 typologically most plausible consonants display high universality in the number of consonants. However, Thai shows higher universality in regards to their substance, i.e. it differs from Korean when it comes to the structure of plosives and fricatives. Both Korean and Thai show similarities regarding the plosives due to the fact that both languages possess three contrastive consonants. However, the Thai plosives consist of plain voiced, plain voiceless and aspirated voiceless sounds that have higher universality than the Korean plosives which are plain voiced, plain voiceless and aspirated voiceless. In case of vowels, both Korean with its 10 vowels and Thai with its 9 vowels show lower universality when it comes to the total number of vowels. However, all of those vowels belong to the list of most plausible vowels which makes their universality higher in substance. In respect of syllable structure, Korean with its CVC type shows a moderately complex structure while Thai with its CCVC type has a complex structure. The coda may consist of only one consonant in each language but onset is composed of one consonant in Korean, and two consonants in Thai. The contrastive study of similarities and differences between Korean and Thai in terms of phonology will help not only understand the two languages but also provide useful information for increasing the efficacy of Korean language education for Thai learners of Korean whose number is rapidly increasing.

This study tests the hypothesis that the voiced-voiceless distinction is influenced by the relationship between acoustics and perception. Production and perception tests are conducted with temporal cues in different environments(CV, VCV, VC). The result showed that acoustic cues indicating significant difference between voiceless/voiced plosives do not behave just as do in perception. The result also showed that there existed an asymmetry between acoustics and perception.

The purpose of this work is to examine the voice onset times (VOTs) of the three types of plosives from the Seoul Corpus male speakers in their twenties. In addition, the factors known to affect VOTs were analyzed, including the place and manner of articulation, speakers, location in words, type of following vowels and speech rates calculated from the three consecutive words. Much of the findings agreed with those from earlier studies on Korean and other languages and new discoveries were made.

The purpose of this work was to examine the factors affecting the identities of the voiceless plosives, i.e. English [p, t, k] and Korean [p^h, t^h, k^h], from the spontaneous speech corpora. The factors were automatically extracted by a Praat script and the percent correctness of the discriminant analyses was incrementally assessed by increasing the number of factors used in predicting the identities of the plosives. The factors included the spectral moments and tilts of the plosive release bursts, the post-burst aspirations and the vowel onsets, the durations such as the closure durations and the voice onset times (VOTs), the locations within words and utterances and the identities of the following vowels. The results showed that as the number of factors increased up to five, so did the percent correctness of the analyses, resulting in 74.6% for English and 66.4% for Korean. However, the optimal number of factors for the maximum percent correctness was four, i.e. the spectral moments and tilts of the release bursts and the following vowels, the closure durations and the VOTs. This suggests that the identities of the voiceless plosives are mostly determined by their internal and vowel onset cues.

In the literature on the tense consonants in Korean, it has been proposed that this consonant is underlyingly represented by a single consonant (the singleton hypothesis) and that it is represented by a sequence of two lenis consonants (the geminate hypothesis). One piece of the empirical evidence supporting the geminate hypothesis is that the closure duration of tense consonants in intervocalic position is more than twice as long in comparison with their lenis counterparts. In this paper, we report on the closure duration of three types of plosives in various phonotactically permitted contexts in Korean. The results of the measurement show that the duration of the tense consonants in post-sonorant contexts is reduced by a third in comparison with that of the intervocalic ones. These temporal differences suggest that the measurement of closure durations in intervocalic position alone is not sufficient to sustain the geminate hypothesis.

The purposes of this study are (1) to see if the length of residence in Korea affects to the VOT values of Korean plosives produced by Chinese speakers (2) to investigate if such VOT values are different in non-sense words and real words and (3) to find out how such VOT values are related to the native Korean speakers' understanding of the words. For these purposes, eighteen Chinese speakers' VOT values of Korean plosives were measured using Speech Analyzer and their pronunciations were evaluated by three native Korean speakers. The results show that there is no effect of both (1) length of residence in Korea and (2) production of non-sensed words and sensed words. In addition, it is noticed that VOT values of some plosives affect more to the native Korean speakers' understanding of the words, while some are not.

Background and Objectives The compensatory articulation not only influences general speech intelligibility, but also prevents precise assessment of the velopharyngeal function. This study was performed to investigate frequently affected phonemes, prevalence and the characteristics of compensatory articulation in the patients with cleft palate having velopharyngeal insufficiency. Material and Method An archival review was taken on 103 cleft palate subjects. Their age ranged from 2.6 to 63 years (mean age of 9.8 years). They were grouped into two : preschool group (n=71) and older patient group (n=32). The prevalence and patterns of compensatory articulation were examined on oral high pressure consonants such as plosives, fricatives and affricates. Results : Compensatory errors were observed in $49.5\%$ of the subjects and were mostly glottal stops with the exception of 4cases who had pharyngeal fricatives in addition to glottal stops. The most frequently substituted phonemes were velar plosives and tense sound. There was no significant difference of prevalence in both groups. However, errors for bilabial and alveolar plosives were more frequently observed in preschool group. Conclusion High prevalence of compensatory articulation observed in both preschool and older age group indicates that their articulation errors tend to remain unless appropriate speech therapy is provided. To improve speech intelligibility of the patients with cleft palate having velopharyngeal insufficiency, it is advisable to address and correct the compensatory articulation errors in their earlier ages.

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.
