The purpose of this study is to revisit the property of the Korean plain stops in intervocalic position. More specifically, focusing on a word-internal, intervocalic position, this study investigates 1) how often speakers pronounce intervocalic. stops as fully voiced, 2) in what amount each speaker voice the plain stops during the stop closure, 3) whether the preceding or the following vowel influences the voicing of target consonants, and 4) the fundamental frequency pattern at the vowel onset after the target consonant shows any consistent pattern, regardless of whether voicing is present during the closure. The results of this study give strong support for the phonetic account of the voicing distinction in Korean. (Jun 1995, 1996).

The purpose of this paper is to study deletion of the Arabic glottal stop /'/ in Literary Arabic(LA) and Cairene Arabic(CA). Arabic has a diglossia structure - Literary and Colloquial Arabic. The former is the standard and written language, while the latter is the oral language used in dialects of many areas. Of the various Colloquial Arabic dialects the Cairene Arabic is the most influential and powerful dialect, hence it was chosen as the subject study. In this paper the followings are found: (1) The deletion of the Arabic glottal stop /'/ in CA is found much more frequently than that in LA. (2) In a word the deletion is found more frequently in the middle position than in the initial or final position, in which /'/ is sometimes converted weak consonants /w/ or /y/.

The goal of this paper is to examine how Case Drop (the drop of the case markers) correlates with the prosodic structure in Korean. On the assumption that intervocalic Lenis Stop Voicing (LSV) applies within the domain of the Accentual Phrase (AP), voicing analyses are performed on intervocalic lenis stop consonants before and after Case Drop. A statistical analysis reveals that the drop of the nominative and accusative case markers significantly alter the AP structure. Pitch values will then be extracted to verify that such changes in the AP structure conform to the pitch properties proposed for the AP (Jun 1993, 1998). The results show that the AP structure suggested by LSV does not always coincide with that imposed by the pitch properties.

The two specific research questions pursued in this paper are: (i) how Korean speakers perceive Hindi stops in terms of the three laryngeal categories of Korean stops; (ii) how well Korean speakers do with an ABX perception test that utilizes a total of 52 Hindi minimal pairs where all sounds are identical except for the laryngeal features of a stop in each word. A total of 45 university students participated in this experiment. The results showed that (i) Koreans tended to perceive Hindi voiceless unaspirated stops as Korean fortis ones, voiceless aspirated stops as aspirated ones, voiced stops as lenis ones, and breathy stops as aspirated ones, and (ii) Koreans had difficulty in distinguishing between voiceless aspirated and breathy stops in Hindi.

Acoustic and aerodynamic characteristics of Cheju consonants were examined with the focus on the well-known three-way distinction among stops (i.e., lenis, fortis, aspirated) and the two-way distinction between sand s*. Acoustic parameters examined for the stops included VOT, relative stop burst energy, Fo at the vowel onset, H1-H2, and H1-F2 at the vowel onset. For the fricatives s and s*, acoustic parameters were fricative duration, Fo, centroid of the fricative noise, RMS energy of the frication, H1-H2 and Hl-F2 at the onset of the following vowel. In investigating aerodynamics, intraoral pressure and oral flow were included for the bilabial stops. Results indicate that, although Cheju and Korean are not mutually intelligible, acoustic and aerodynamic properties of Cheju consonants are very similar in every respect to those of the standard Korean. Among other findings there are three crucial points worth recapitulating. First, stops are systematically differentiated by the voice quality of the following vowel. Second, stops are also differentiated by aerodynamic mechanisms. The aspirated and fortis stops are similar in supralaryngeal articulation, but employ a different relation between intraoral pressure and flow. Finally, our study suggests that the fricative s is better categorized as 'lenis' than as 'aspirated' in terms of its phonetic realization.

It is known that Korean stop consonants in syllable-initial position are of three types : lax, aspirated and forced (or unaspirated). In syllable-final position, however, these three different types are merged to a single type with the same place of articulation, although the original three-way distinction is preserved in Korean orthographic (Hangul) system. Thus the syllable-final stops are phonetically realized as voiceless "applosives" which are characterized by the absence of oral release. The aim of the present study is to investigate the laryngeal adjustments for these syllable-final stops in various phonological conditions by using fiberscope, and, is to further investigate electromyographically the laryngeal adjustments for Korean stops both in the syllable-initial and final positions in various phonological conditions. The results can be summarized as follows : 1. In the case of syllable-initial stops, the glottal widths in each three types of the Korean stops during the articulatory closure are clearly different. And the pattern of thyroarytenoid(VOC) activity appeared to characterize the three different types of Korean stops. 2. The basic laryngeal feature of the Korean syllable-final applosives is characterized by a small degree of glottal opening which begins at or slightly after the oral closure. 3. In the case, syllable-final stop followed by the copula "ita", the syllable- final stop is pronounced as the stop consonant at the initial position of the following syllable containing the vowel[i], the underlying features of three-way distinction for the stops in the Korean orthographic(Hangul) system being manifested at the laryngeal adjustment. 4. In the case of the final applosives followed by the initial stops and fricatives, the laryngeal feature of the final applosives appears to be assimilated by that of the following consonant irrespective of the difference in the place of articulation, as far as the glottal abduction/adduction is concerned. It is clearly demonstrated in the case of syllable-initial stop that thyoarytenoid(VOC) activity is suppressed for the production of the stop consonants in question, the degree of which is slightest for the forced type and most marked for the aspirated type, while it is moderate for the lax type.

General American English(=A.E.) has conservative elements as well as progressive elements. A.E. and B.E. are languages which have more similarities than differances. In this paper. I studied the process of English progress before the A.E. had come into being, and the historical background and the cahristics of A.E. coming into being. Considering the differences between A.E. and B.E. from spelling, pronunciation, vocabulary and grammar, I can give the outline as follows. A spelling 1. B.E. : au, ou $${\rightarrow}$$A.E. : a, o 2. B.E. : e $${\rightarrow}$$A.E. : i 3. B.E. : $${\ae}$$ oe $${\rightarrow}$$A.E. : e 4. B.E. : our $${\rightarrow}$$A.E. : or 5. B.E. : re $${\rightarrow}$$A.E. : er B. pronunciation 1. B.E. : [e] $${\rightarrow}$$A.E. : [i], [e], $$[\partial]$$ 2. B.E. : [a] $${\rightarrow}$$A.E. : 3. B.E. : [i(:)] $${\rightarrow}$$A.E. : [ai], $$[\partial]$$, $$[{\varepsilon}]$$ 4. B.E. : $$[{\ae}]$$ $${\rightarrow}$$A.E. : [e], [c] 5. B.E. : [ai] $${\rightarrow}$$A.E. : $$[{\ae}]$$, [e] 6. B.E. : [c] $${\rightarrow}$$A.E. : [e], [a], [o] 7. In case of "Vowel+[t]+Vowel", [t] is pronounced into [d] or [r] 8. In case of "-nt", [t] becomes a mute. 9. [t]+[j, l, m, n, r, u, or, w] $${\rightarrow}$$A.E. : [?] (=glottal stop) 10. B.E. : [w] $${\rightarrow}$$A.E. : [hw] 11. B.E. : [Voiceless consonants], [Voiced consonants] $${\leftarrow}$$A.E. : [Voiced consonants], [Voiceless consonants] C. Vocabulary The historical background and geographical conditions of those days caused lots of new compounds and neologies. D. Grammar Though we use "of" to indicate the possessive case of inanimate object, -s genitive is used in A.E. In the perfect tense, "have" is often omitted and also auxiliary verb "will" is used in any case

The present study investigates supralaryngeal articulatory characteristics of denti-alveolar (coronal) stops /t, $t^h$, $t^*$/ and /n/ in /aCa/ context in Seoul Korean. An Electromagnetic Articulograph (EMA, Carstens) was used to explore kinematics of the consonants by examining the kinematic data of the tongue tip (the primary articulator for the coronal consonants), along with some additional supplementary position data of the tongue body, the tongue dorsum and the jaw. The results showed that the constriction duration was the most robust articulatory correlates of the three-way stop contrast with a pattern of /t/$t^h$/$t^*$/. The contrast was further reinforced by the tongue body position (higher for /$t^h$, $t^*$/) and the tongue tip opening displacement (less displaced for /$t^h$, $t^*$/). The articulation of /n/ was quite similar to that of the lenis /t/ in terms of the constriction duration, and it was different from the oral stops in that it was produced with larger tongue tip displacement and lower jaw position than the oral stops, indicating its weak articulatory nature. The results are also discussed in comparison with those of bilabial stops with implications that the three-way contrast may be kinematically expressed differently depending on the physiological constraints imposed on the primary articulator (the tongue tip versus the lips). The present study, therefore, provides new articulatory (kinematic) data of denti-alveolar consonants in Korean, and demonstrates that the three-way stops, that have been known to differ primarily in their laryngeal settings, are indeed produced with kinematic distinctions at the supralaryngeal level.

Based on the observation that Korean speakers of English have difficulties in producing English fricatives, a perception experiment was designed to investigate whether Korean speakers also have difficulties perceiving English labial consonants including fricatives. Forty Korean college students were asked to perform a multiple-choice identification test. The consonant perception test consisted of nonce words which contained English labial consonants [p, b, f, v] in 4 different prosodic locations: initial onset position, intervocalic position before stress, intervocalic position after stress, and final coda position. The general perception pattern was that the mean accuracy rates were higher in strong position like CV and VCVV than in weak position like VC and VVCV. The difficulties in perceiving the English targets resulted mainly from bidirectional manner confusion between stop and fricative across all prosodic locations. The other types of misidentification were due to place confusion as well as voicing confusion. Place confusion was generated mostly by the target [f] in all prosodic position due to acoustic properties. Voicing confusion was heavily influenced by prosodic position. The misperception of the participants was accounted for by phonetic properties and/or the participants' native language properties.
