Ellipsis is the figure of speech characterized by the deliberate omission of words that are obviously understood, but that must be supplied to make a construction grammatically or semantically complete. The purpose of this study is to examine how ellipsis affects its adjacent elements acoustically and phonologically in English VP-ellipsis, sluicing and gapping. In the experiment, the realizations by English native speakers are set as the criteria for the observing point and are compared to Korean speakers' realizations. For the results, while English native speakers utilized various acoustic information such as word duration and pitch range and phonological information such as pith accent realization in order to intend the cues for decoding the missing constituent, Korean English learners relied on only duration information and could not use various information effectively.

The purpose of this paper is to examine how Chinese speakers realize Korean prosodic phrases in the reading of Korean texts. Prosodic phrase, in this study, is defined as basic unit of spoken language which can be perceived as purely separate phonetic unit by both hearer and speaker, and is realized with a coherent intonational configuration. Prosodic phrase plays an important role in both speech production and perception. In the second language acquisition, prosody influences the accuracy and fluency of spoken language. The main purpose of this study is to describe the aspect of syntagmatic operation of prosody that produces prosodic phrases. We have specifically examined the relations between the prosodic phrase's boundary and its syntactic status. Furthermore, we examined internal syntactic structure of each prosodic phrase. And the results of each analysis were compared to the aspects of prosodic phrases' formation produced by native Korean speakers. The results show that Chinese speakers tend to coincide the prosodic phrases with syntactic structure more than native Korean speakers.

It have been known that Daegu dialect does not have /ㅆ/ as a phoneme. However, it seems that /ㅅ/ and /ㅆ/ are phonemically distinctive in younger generation. In this paper, we investigate realization of /ㅅ/ and /ㅆ/ of Daegu dialect in their 20's, and compare them with /ㅅ/ and /ㅆ/ of Seoul dialect in their 20's. The result of this study showed that /ㅅ/ and /ㅆ/ were not significantly different between Daegu and Seoul dialect except pitch. Therefore, in Daegu dialect /ㅅ/ and /ㅆ/ are phonemically distinctive in younger generation like Seoul dialect's /ㅅ/ and /ㅆ/ are.

고령화 혹은 국제화와 같은 변화 양상은 다가오는 21세기의 새 시대를 가치기준에서 뿐만 아니라 사회환경까지도 새로운 것을 추구하도록 요구해 가고 있다. 이것은 도로교통에 있어서도 마찬 가지로 지금까지 양적인 팽창 위주로 전개되던 것이 효율을 중시하지 않으면 안 되게 되었으며 특히 20세기 후반들어 반도체 기술과 함께 급격한 발전을 거듭하고 있는 컴퓨터 기술은 정보 통신 기술과 함께 도로교통의 새로운 장을 열어 갈 것으로 예측된다. 21세기의 도로 교통을 생 각할 때, 차량 보급 대수의 증가와 함께 지금도 교통사고가 커다란 사회 문제로 대두되고 있는 추세로 볼 때, 중심이 되는 단어는 역시 '안전'과 '환경'이겠지만 그 가운데에도 교통 사고의 저 감은 무엇보다 시급한 과제라 할 수 있으며 대기 오염을 비롯한 물리적 환경의 개선과 보다 원 활하고 쾌적하게 달릴 수 있는 교통 환경의 실현도 중요한 과제가 될 것이다. 이 글에서는 이 러한 관점에서 21세기의 도로교통과 이를 이루어가기 위한 기술적 과제들을 살펴보고자 한다.

The purpose of this study is to examine the pitch pattern of Korean accentual phrases produced by Chinese Korean-learners in the reading of a Korean text. Korean accentual phrase is determined by a specific F0 contour. And the pitch contour of APs differ depending on their length and the nature of initial segment. In order to examine if Chinese speakers are also aware such a phonetic properties, we have examined the AP pitch contours produced by 15 Chinese speakers differing in proficiency, and compared them to pitch contours produced by six Korean native speakers. The results show that Chinese speakers' pitch errors were observed in initial segment-tone interaction and in type of pitch patterns. However, even though Chines speakers produced the same type of pitch patterns, internal tonal modulation differs from native speakers. Finally, on the basis of theses results, we proposed a teaching method that visualizes the F0 contour.

The sentences with the same surface word order may be realized with the pragmatically different meanings, depending on the contexts under which they could appear. Semantically, their meaning differences have been explained in terms of the different information structures (Steedman 2000), whereas prosodically, they can be explained in terms of the different compositions of intonational components which make their own semantic contributions (Pierrehumbert and Hirschberg 1990). In other words, the different intonation realizations of the sentences with the same word order reflect the different information structures. In this paper, we investigate the relationship between the information structure and the intonational meaning by way of analysing the production of the sentences with ambiguous scopes of the English focus particle 'only'. In contrast to the previous quantitative approaches to the scopes of the focus particle 'only', two independent levels of information structure (Steedman 2000)-theme/rheme, and focus/ background-make it possible to consistently explain the intonational phenomena.

This paper attempts to examine the accent implementation and perception of noun phrases and compound nouns in English sentences, arguing that primary stress of noun phrase and compound noun is realized in relative prominence in intonation. The production test examines how the stress patterns of the noun phrases and compound nouns are realized in intonation of the English native speakers' utterances. The perception test investigates English and Korean listeners' comprehension of the intonation of the noun phrases and compound nouns. And the results of this experimental study show that speakers and listeners produce and perceive the primary stress as a relatively prominent accent even if in contrast of English listeners, Korean learners have difficulty in using the cue of pitch accent location and figuring out compound nouns and noun phrases.

The purpose of this paper is to examine how Chinese speakers realize Korean intonation phrase (IP) boundary tones in the reading of a Korean text. Korean IP boundary tones play various roles in speech communication. They indicate prosodic constituents' boundaries while simultaneously performing pragmatic and grammatical functions. In order to express and understand Korean utterances correctly, it is necessary to understand the Korean IP boundary tone system. To investigate the IP boundary tone produced by Chinese speakers, we have specifically examined the type of boundary tones, the degree of internal pitch modulation of boundary tones, and the pitch difference between penultimate syllables and boundary tones. The results of each analysis were compared to the IP boundary tones produced by Korean native speakers. The results show that IP boundary tones were realized higher than penultimate syllables.

본 연구는 한국어 음성-텍스트 데이터에서 보편적으로 나타난 휴지의 실현 양상을 분석하고, 이를 토대로 데이터셋을 선별해 보편적이고 규격화된 한국어 휴지 예측을 위한 모델을 제안하였다. 이를 위해 전문적인 발성 훈련을 받은 성우 등의 발화가 녹음된 음성-텍스트 데이터셋을 수집하고 MFA와 같은 음소 정렬기를 사용해 휴지를 라벨링하는 등의 전처리를 하고, 다양한 화자의 발화에서 공통적으로 나타난 휴지를 선별해 학습데이터셋을 구축하였다. 구축된 데이터셋을 바탕으로 LLM 중 하나인 KULLM 모델을 미세 조정하고 제안한 모델의 휴지 예측 성능을 평가하였다.
