Korean intonation has been investigated mainly from the point of view of impressionistic phonetics and phonology. The purpose of this paper is to investigate Korean intonation especially nuclear tones, from the point of view of experimental phonetics. Since what we hear is not always the always as what we see in fundamental frequency contours, acoustic characteristics of Korean nuclear times are first discussed Based m quantitative data similar nuclear times are compared and the relationship between the nuclear ton and sentence type is investigated The relationship between the nuclear tone and the speaker's attitude is also discussed.

It is generally said that falling intonation is used at the end of a declarative sentence. However, this is not the case with all stretches of spontaneous speech which are marked in transcription as sentences. The present paper examines intonation patterns appearing at the end of declarative sentences in oral presentations, and discusses instances where falling intonation does not appear. The texts used for analysis are eight oral presentations collected at international conferences in the field of physics. Quantitative and qualitative analyses are carried out. Three major factors related to discourse structure have been found for non-occurrence of falling intonation at sentence boundaries.

This paper attempts to investigate characteristic features of Japanese EFL learners' English intonation and how their Japanese accents are affecting their English intonation, focusing on a comparison between the accent patterns of Japanese compounds and the stress patterns of English compounds. It is based on research dedicated to helping to improve the teaching and learning of English intonation (prosody) for Japanese EFL learners. It examines the Fundamental Frequency (henceforth Fx) contours of two EFL college students, one specializing in English and the other in Japanese. Both of them may be considered upper intermediate EFL students with their TOEFL (Test of English as a Foreign Language) scores ranging between 500 and 550.

The purpose of this paper is to design Speech Database for Korean pronunciation education. For this purpose, I investigated types of speech errors of Korean-learners, made texts for recording, which involves all types of speech errors, and showed how to gather speech data and how to tag their informations. It's natural that speech data should include Korean-learners' speech and Korean people's speech, because Speech DB that I try to develop is for teaching Korean pronunciation to foreigners. So this DB should have informations about speakers and phonetic informations, which are about phonetic value of segments and intonation of sentences. The intonation of sentence varies with the type of sentence, the structure of prosodic units, the length of a prosodic unit and so on. For this reason, Speech DB must involve tags about these informations.

One of the learning difficulties for Korean learners of English is the intonation of English focused yes/no questions. Focused words in English yes/no questions are realized as low pitch accents which contrast with high pitch accents in Korean counterparts. In order to improve Korean students' intonation, direct and metalinguistic explanations on the intonation of English focused yes/no questions were given to Korean learners of English. In pre-tests and post-tests, students' perceptions on the target items were measured. The study results showed that phonetic explanation using intonation contour enhanced students' perception on English intonation. With respect to the position of focused words, sentence initial and medial focused questions were more difficult than sentence final focused questions. The perception was most improved in sentence initial focused questions. The study showed the immediate effects of the explicit instruction on perceptions of English intonation.

This is a pilot study on applying the Rise/Fall/connection(RFC) model to Korean intonation tot speech synthesis. RFC model contains successive intonation events, which can be pitch accents and intonation boundary tones. The intonation contour of RFC model is composed of piecewise linear curves of rise, fall, and connection elements, and each element can have any amplitude and duration. In this paper, elements of RFC model is slightly modified to accommodate the characteristics of Korean intonation. Subjective preference test was conducted to compare the modified RFC model with the original one. The results show that the intonation contour produced by the modified RFC model is perceptually indistinguishable from that of the original RFC model, while the former requires less number of labels than the latter.

Information structure can be conveyed by prosodic structure (Poser 1984 for Japanese; Inkelas and Leben 1990 for Hausa; Cho 1990 for Korean; Hayes and Lahiri 1991 for Bengali; Selkirk and Shen 1990 for Shanghai Chinese). Different subfields of linguistics and different theoretical perspectives suggest many distinct types of information structure: topic vs. comment, focus vs. background. old vs. new information, etc. The purpose of this paper is to investigate phonetic realizations of focus and topic among these information structures in Korean. For this purpose, we conduct a phonetic experiment where we examine duration, pitch and dephrasing in focus and topic structures. We make four findings through this study. First, duration of 'nun' varies depending on the information structure of the following constituent. Second, the degree of accentual phrase-initial rising is larger in contrastive topic and focused phrases than in neutral phrases. Third, a contrastive topic phrase always constitutes an Intonation Phrase on its own. Fourth, dephrasing occurs variously depending on gender and the number of the syllables within a phrase.

This research is for finding prototypes and characteristics of intonation found in ${\ulcorner}$-a/e, $t{\int}ijo$<${\lrcorner}$ and ${\ulcorner}$p/simnida${\lrcorner}$ among modern Korean predicate statements by constructing spoken corpus based on the current radio broadcast. So the result of the study is as follows. : (1) The construction of the balanced spoken corpus and the standard for boundary determination of rhythm are needed for the intonation model of speech synthesis. (2) Korean intonation units have the splited word tone which includes the nuclear tone and the pre-nuclear tone makes unclear tone more detailed. (3) I made man and woman intonation models individually through t-test of SPSS. (4) The standard intonation model is devided '-ajo'type and '-nida'type

This paper aims to propose how to extract intonation patterns using Momel, a pitch stylization algorithm, and to present results of analyzing speech corpora in comparison with those in earlier researches. Two speech corpora are used: one is the sound files obtained from the K-ToBI web site, and the other consists of 80 passages pronounced by 4 speakers (2 male and 2 female). The results show that Momel provides significant pitch targets which can be labeled as H and L tones within prosodic units such as Accentual Phrase (AP) and Intonation Phrase (IP). The resulting AP patterns and IP boundary tone patterns correspond to those in earlier researches. Thus, this study will contribute to the study of intonation as well as to the development of automatic intonation labeling systems.
