Linguistically, 'Focus' is the element which includes new or unpresupposed information. It is usually signalled by prosodic prominence called the 'pitch accent'. The purpose of this study is to observe the realization of the focal accent in VP-ellipsis, especially, to affect the meaning recovery of elided VP. Asher (1999) gave evidence that focal stress should be on the higher verb and the AUX in order to recover the elided VP to the lower one. In this paper, the systematic patterning of focal accent to decide the elided meaning in VP-ellipsis is to be observed. The realization of focal accent by English native speakers is set as the criteria for the meaning recovery of the elided VP and is compared to Koreans'. Moreover, the focal accents of Koreans are observed and compared with respect to their English proficiency levels.

In this paper prosodic characteristics of French language are analysed with a corpus of radio interview. Intonation patterns are interpreted in terms of raising pattern, focal raising pattern and falling pattern. Accentual prominence is classified in two types, rhythmic accent and focal accent. Focal accent permit to explain the cohesion in a utterance or between two utterances. As a prosodic variable of discourse pauses are described by their form of realization (filled pause, silent pause, hesitation etc), their distribution and their function in utterance.

The current study exploresacoustic variation induced by prosodic contexts in different speech styles,with a focus on motherese or child-directed speech (CDS). The patterns of variation in the acoustic expression of voicing contrast in English stops, and the role of prosodic factors in governing such variation are investigated in CDS. Prosody-induced acoustic strengthening reported from adult-directed speech (ADS)is examined in the speech data directed to infants at the one-word stage. The target consonants are collected from Utterance-initial and -medial positions, with or without focal accent. Overall, CDS shows that the prosodic prominence of constituents under focal accent conditions variesin the acoustic correlates of the stop laryngeal contrasts. The initial position is not found with enhanced acoustic values in the current study, which is similar to the finding from ADS (Choi, 2006 Cole et al, 2007). Individualized statistical results, however, indicate that the effect of accent on acoustic measures is not very robust, compared to the effect of accent in ADS. Enhanced distinctiveness under focal accent is observed from the limited subjects' acoustic measures in CDS. The results indicate dissimilar strategies to mark prosodic structures in different speech styles as well as the consistent prosodic effect across speech styles. The stylistic variation is discussed in relation to the listener under linguistic development in CDS.

This study investigates the accentual realization of negation denying the presupposition of a previous utterance compared with that of a general negation. Specifically we study what types and positions of accent are realized in the speech of Korean speakers using English as a second language as well as English native speakers. Gussenhoven (1983) and Bolinger (1985, 1986) suggested that when presupposition of previous utterances is denied through negation, focal accent is assigned to empty (functional) words, rather than negative morphemes. The results of this study, however, show that negation sentences denying presupposition have accents not only on empty (functional) words but also on content words. Almost every English native speaker places an H* accent on the negative morphemes themselves (not, no, nothing, etc.) in general negation, as well as on the other lexical items-verbs and prepositions in our data-in negations denying presuppositions. On the other hand, Korean speakers hardly distinguish between the two kinds of negation sentences, unlike native speakers through accentual differences. Rather, they give accent an every content word, including the negative morphemes in both general negations and negations denying presuppositions. Therefore, the results of this study do not absolutely support the previous studies on the denial of presupposition.

The current study observes the durational interaction of tautosyllabic consonants and vowels in the word-initial position of English and Korean child-directed speech (CDS). The effect of phonological laryngeal contrasts in stops on the following vowel duration, and the effect of the intrinsic vowel duration on the release duration of preceding stops in addition to the acoustic realization of the contrastive segments are explored in different prosodic contexts - phrase-initial/medial, focal accented/non-focused - in a marked speech style of CDS. A trade-off relationship between Voice Onset Time (VOT), as consonant release duration, and voicing phonation time, as vowel duration, reported from adult-to-adult speech, and patterns of durational variability are investigated in CDS of two languages with different linguistic rhythms, under systematically controlled prosodic contexts. Speech data were collected from four native English mothers and four native Korean mothers who were talking to their one-word staged infants. In addition to the acoustic measurements, the transformed delta measure is employed as a variability index of individual tokens. Results confirm the durational correlation between prevocalic consonants and following vowels. The interaction is revealed in a compensatory pattern such as longer VOTs followed by shorter vowel durations in both languages. An asymmetry is found in CV interaction in that the effect of consonant on vowel duration is greater than the VOT differences induced by the vowel. Prosodic effects are found such that the acoustic difference is enhanced between the contrastive segments under focal accent, supporting the paradigmatic strengthening effect. Positional variation, however, does not show any systematic effects on the variations of the measured acoustic quantities. Overall vowel duration and syllable duration are longer in English tokens but involve less variability across the prosodic variations. The constancy of syllable duration, therefore, is not found to be more strongly sustained in Korean CDS. The stylistic variation is discussed in relation to the listener under linguistic development in CDS.

Focal parts of utterance can be determined by new/contrastive information, a focus particle, a contrastive topic marker, or a nominative case marker in Busan Korean. Among these factors, new or contrastive information is the most important element in determining the intonational nucleus of an utterance. However, unlike Seoul Korean, when a focus particle, a topic marker, or a case marker contributes to the placement of the most prominent peak of an utterance, the peak is on the noun to which they are attached. Moreover, the case marker-ga shows more prominent pitch on the preceding noun than the noun followed by the topic marker-nun when-ga is used as emphatic or contrastive. This is one of the major problems for Busan Korean users in commanding natural and fluent Seoul Korean intonation even if they use standard written form of Seoul Korean in their speech.

This paper presents results from speech production experiments on English, Korean, and Hindi that compare variation in the acoustic expression of dissimilar phonological laryngeal contrast in stops conditioned by prosodic prominence. Target stops are analyzed from utterance-initial, -medial, and -final positions, with a variation in contrastive focal accent, from the speech data by six male American English speakers, five male Seoul Korean speakers, and five male Delhi Hindi speakers. The results show that prosodic prominence conditions enhanced distinctiveness between contrastive segments in the three languages. The manner in which prosodic prominence and prosodic phrase structure is marked at the level of segmental variation is, however, found to be language-specific to some extent. In addition, a correlation between the size of the phonological inventory and the corresponding acoustic variation was found but the linear correlation was not strongly supported with the findings in the present study.

본 연구는 동궐도에 나타난 괴석의 배치를 바탕으로 조선시대 궁궐에 쓰인 괴석의 배석형식과 활용을 고찰한 것이다. 동궐도에서 축선을 보조하여 정형성을 형성하는 괴석 배열의 종류는 단식, 대식, 연식으로 구분된다. 단식은 기존 건축물을 통해 형성된 축선상에 괴석 1개를 배치하여 시각적 초점을 부여하거나 중심성을 강조하기 위해 사용되었다. 대식의 경우, 주로 건물 양옆에 괴석 2개를 대칭구도로 놓아 건축물에 질서와 위계를 부여하기 위해 사용되었다. 또한 세 개의 돌을 나열한 연식은 주석(主石)의 역할을 하는 가운데 돌이 축선 상에 놓여 강한 방향성과 정면성을 부여하는 방법으로 사용된다. 이러한 괴석 배치법은 수목의 배식에도 동일하게 적용되는 것으로, 수목의 요점식재와 대칭식재 방법에서 유사성이 발견되었다. 따라서 괴석과 수목은 장소의 성격과 규모에 따라 취사선택될 수 있으며, 축 형성과 정형적 공간창출의 효과는 근본적으로 같다고 할 수 있다. 이상의 결과를 바탕으로 동궐도 괴석의 배치 특성을 고찰한 결과는 다음과 같다. 첫째, 괴석은 중요한 건물에 위계를 표현하기 위해 설치되어 구심적인 공간을 창출하는 수단으로 사용되었다. 둘째, 괴석간 거리는 가운데에 있는 건축물의 크기에 비례하여 조정되었으며, 이는 중심축과 좌우 대칭물 간의 비례적 균형구도를 통해 안정감을 부여하기 위함이었다. 셋째, 불규칙한 괴석의 외형이 규칙적인 대칭성을 형성하는데 제한요소가 되므로 석함을 활용하여 정형성을 더하였다. 넷째, 연식(3입식) 배치에서 가운데 괴석에 변화를 주어 중심성을 강조하였다. 다섯째, 괴석은 타 점경물의 종류와 배합 및 위치조정이 수월하도록 크기를 제한함으로써 얻어지는 이동성이 있었다. 여섯째, 사의적 대상으로 감상되던 궁궐 괴석은 근본적으로 수석과 동질적인 개념의 조형물 이었으며 감상되는 방법, 형태, 구성에서 같은 맥락으로 전개되었다. 일곱째, 연식으로 놓인 괴석은 짝수일 경우 균등분할 식으로 배치되며, 홀수일 경우 중심 괴석을 중심으로 나머지가 대칭하도록 배열하는 방법을 따랐다. 이상의 배석원칙은 조선 궁궐에서 괴석을 제작하고 활용했던 특징적인 방법으로 판단된다.
