This paper investigates how focus contributes to the phonological and phonetic realization of Japanese intonation. Pierrehumbert & Beckman (1988) pointed out that textual prominence results in the H-tone peak raising on the focused item and IP (Intonational Phrase) initiation before the focused item. Similarly Kori (1989) suggested that the F0 peaks on the words after the focused item tend to be suppressed. Although they give a general description of the characteristics of focus phenomena in Japanese intonation, they fail to explain the F0 peak interaction between H phrasal tone and lexically specified pitch accent in more-than-3-mora words whose accent locations varies from early to late. In this paper, we perform the experiment to investigate the following three points. First, we would like to look at the systematic intonational differences between focused and neutral APs; specifically, focused APs, either accented or unaccented, are compared with the neutral counterparts in terms of F0 pattern. Second, we investigate F0 patterns of a focused AP with more than 3 morae, as the accent of the word varies from early to late. Since an AP with a late accent has a H- on the second mora as well as H*+L on its accent mora, it is expected that these peaks will show systematic F0 pattern when it is focused. Our third concern is F0 patterns of a post focus AP with more than 3 morae, that is, whether a post-focus word is dephrased or just downstepped as the word accent location varies from early to late. This paper is significant in that it tries to clarify the F0 peak interaction between H-and lexical pitch accent H*+L in a variety of focus contexts in Japanese intonation.

Among the scholars of second language (L2) acquisition who have used prosodic considerations in syntactic analyses, pausing and intonation contours have been used to define utterances in the speech of second language learners (e.g., Sato, 1990). In recent research on conversational analysis, it has been found that lexically marked causal clause combining in the discourse of native speakers can be distinguished as "intonational subordination" and "intonational coordination(Couper-Kuhlen, Elizabeth, forthcoming.)". This study uses Pienemann's Processability Theory (1995) for an analysis of the speech of native speakers of Japanese (L1) learning English. In order to accurately assess the psycholinguistic stages of syntactic development, it is shown that pitch, loudness, and timing must all be considered together with the syntactic analysis of interlanguage speech production. Twelve Japanese subjects participated in eight fifteen minute interviews, ninety-six dyads. The speech analyzed in this report is limited to the twelve subjects interacting with two different non-native speaker interviews for a total of twenty-four dyads. Within each of the interviews, four different tasks are analyzed to determine the stage of acquisition of English for each subject. Initially the speech is segmented according to intonation contour arid pauses. It is then classified accoding to specific syntactic units and further analysed for pitch, loudness and timing. Results indicate that the speech must be first claasified prosodic ally and lexically, prior to beginning syntactic analysis. This analysis stinguishes three interlanguage lexical categories: discourse markers, coordinator $s_ordinators, and transfer from Japanese. After these lexical categories have been determined, the psycholinguistic stages of syntactic development can be more accurately assessed.d.

본 연구는 제 2언어 억양습득 과정에서 나타나는 언어 보편적 간섭현상인 피치대역(음역) 축소현상과모국어 간섭현상이 어떤 양상으로 상호작용하며 한국어 습득과정에서 어떤 순서로 나타나는지 중국인 한국어 학습자들을 통해 살펴보았다. 본 연구에는 7명의 한국어 원어민 화자와 초·중·고급 수준의 중국인 한국어 학습자 각 10명 총 37명이 발화 실험에 참여하였다. 연구 참여자들은 난이도가 다른 한국어 담화 4개와 이를 중국어로 번역한 중국어 담화 4개를 낭독 발화하였다. 한국어화자와 중국인 학습자들이 산출한 음성자료는 음성분석 프로그램 Praat을 사용하여 각 문장별로 Pitch span, Pitch level, Pitch dynamic quotient(PDQ), 왜도와 첨도를 측정하였고 이후 언어 간 분석, 그룹 간 분석, 그룹 내 분석을 통해 두 현상의 상호작용양상을 살펴보았다. 언어 간 분석결과 중국어는 한국어보다 높은 Pitch span과 Pitch level로 특징지어졌다. 이를 바탕으로 초·중·고급 중국인 학습자들의 한국어 발화문에 대한 그룹 간 분석을 실시하였다. 그 결과 초급과 중급 학습자들에게서는 모국어 간섭보다는 음역 축소현상이 두드러지게 나타났으며 고급 학습자들은 음역 축소현상이 완화되어 한국 화자에 근접한 양상을 보여주었다. 중국인 학습자들이 발화한 목표어인 한국어와 모국어인 중국어 문장을 대상으로 한 그룹 내 분석에서도 숙달도가 높을수록 모국어와 목표어 간 피치 편차가 줄어들어 음역 축소현상이 완화되었다. 문장 내 피치 변동 범위를 파악하기 위한 PDQ분석에서 중국어 문장은 한국어 문장보다 음역 변동범위가 크다는 것을 알 수 있었다. 그룹 간 분석에서는 초·중급 학습자들의 PDQ가 한국어와 중국어보다 현저히 낮은 값을 보였다. 고급학습자들도 한국어나 중국어보다 낮은 수치를 보였으나 한국어에 근접한 양상으로 나타났다. 이상의 결과를 바탕으로 숙달도가 낮은 화자일수록 음역 축소 현상이 두드러지게 나타나며 고급 화자의 경우 목표어인 한국어와 유사한 양상으로 실현됨을 알 수 있었다. 따라서 본 연구의 분석 대상인 음성학적 층위에서는 모국어 간섭현상이 뚜렷하게 관찰되지 않았다.

This study compared the relative contributions of intensity, F0, duration and vowel spectra of L2 English lexical stress by Japanese and Korean learners of English. Recordings of Japanese, Korean and native English speakers reading eighteen 2 to 4 syllable words in a carrier sentence were analyzed using multiple regression to investigate the influence of each acoustic correlate in determining whether a vowel was stressed. The relative contribution of each correlate was calculated by converting the coefficients to percentages. The Japanese learner group showed phonological transfer of L1 phonology to L2 lexical prosody and relied mostly on F0 and duration in manifesting L2 English stress. This is consistent with the results of the previous studies. However, advanced Japanese speakers in the group showed less reliance on F0, and more use of intensity, which is another parameter used in native English stress accents. On the other hand, there was little influence of F0 on L2 English stress by the Korean learners, probably due to the transfer of the Korean intonation pattern to L2 English prosody. Hence, this study shows that L1 transfer happens at the prosodic level for Japanese learners of English and at the intonational level for Korean learners.

The purpose of this experimental study is to investigate characteristics of English pitch accents uttered by Korean speakers. Six English sentences were uttered five times by fifteen male undergraduate and graduate students from three groups, Seoul, Yongnam and Honam dialect speakers. We compared the subjects' data with the data of a native speaker of English as model pronunciation of English pitch accents. Acoustic features(Fo, duration, amplitude) were measured from sound spectrograms made by the PC Works. Results showed that (1) acoustic features of English pitch accents are Fo and duration for the native speaker and Korean speakers altogether, (2) Seoul dialect speakers uttered English pitch accents more similarly to the English native speaker than the other dialect speakers and (3) Korean speakers generally have difficulties in pronouncing L* accents. It appears that Korean speakers have more problems in pronouncing L* accents than H* accents.

The aim of this paper is to examine the sentence final tonal patterns of English wh-questions through phonetic experiments, based on Intonational Phonology, and to explain the meaning of the final phrase tones of English wh-questions. Pierrehumbert and Hirschberg (1990) suggested that it is pitch accents rather than boundary tones which play a crucial role in the meaning of a sentence, and that most of the general questions have H-H% tonal patterns in the sentence final. However, they could not explain why wh-questions had final falling tonal patterns (L-L%). While Bartels (1999) suggested that L phrase tone has the meaning of 'ASSERTION' and it could be applied to the explanation of the meaning of wh-questions' final tonal patterns. However, her suggestions are only theoretical explanation without any experimental support. In this paper, based on Bartels (1999), the data was classified into the following three classes: 1) echo wh-questions, 2) reference questions, and 3) common wh-questions. Using this data, a production test by three English native speakers was conducted. The results show that reference questions and common wh-questions have L phrase tones in the sentence final at a high rate, and echo wh-questions have H phrase tones in the sentence final at a high rate.

외국어학습의 성공여부는 학습자의 강한 동기유발에 달렸는데, 현재 우리나라에서는 영어학습의 강세에 밀려 프랑스어를 포함한 제 2 외국어 학습 열의가 점차 사라져 가고 있는 실정이다. 각 대학에 프랑스어를 전공하는 학과가 존재하는 한, 프랑스어 교육은 계속되어질 것이나, 과거와는 달리 고등학교에서 프랑스어의 기초를 배우고 대학의 프랑스어 학과에 입학하는 학생의 수가 점차 줄어들고 있다. 또한 현재의 대학 입시 제도가 학생들의 학과에 대한 적성 여부와 상관없이 수능성적 결과 점수에 따라 학과를 정하게 되므로 처음부터 프랑스어를 배우고자 하는 동기가 결여된 상태에서 전공 언어 학습을 시작하게 된다. 프랑스어를 가르치면서 현장에서 가장 고심하게 되는 문제는 첫째 학생들에게 어떻게 하면 프랑스어에 대한 흥미를 유발시킬 수 있는가 하는 점이고, 둘째로는 대학 4년이라는 짧은 기간 동안 어떻게 하면 정확한 프랑스어를 학습시킬 수 있는가 하는 것이다.

This paper attempts to investigate the tonal implementations of English stress clash, arguing that a preceding stress shifts leftward when two lexical stresses conflict across word boundaries or that H* and L* pitch accents are alternatively manifested on the stressed syllables, establishing intonational peak and valley contours. We claim that the H*/L* alternation might be a tonal strategy to avoid stress clash, and that pitch could be solely manipulated to display a rhythmic effect with maintaining lexical stress. In the experiment, we examined two-word combinations whose boundaries involve stress clash, and divided them into two categories. One has the preceding words involving a heavy syllable ahead of stress to guarantee the place for a shifting stress and the other, a light syllable, in which case stress shift is completely prevented. We analyzed the distribution of pitch accents in the word combinations, focusing on the pitch configurations in the cases where stress should not be shifted. Results show that approximately 50% of the stimuli show stress shift in the heavy syllable combinations of the preceding words; the preceding stress is moved leftward within the word. The other 50% and the light syllable combinations show various pitch accents patterns; H* and L* alternation, deaccentuation of either stressed syllable, or L-insertion between two H* pitch accents, etc. We interpret this as a rhythmic effect of tone to avoid stress clash and suggest that a true stress clash would be confined into cases without H*/L* contours.

본 논문의 목적은 한국어 원거리 음성의 운율적 특성을 규명하는 것으로, 36개의 2음절어를 4명의 화자 (여성 화자 2명, 남성 화자 2명)가 원거리 환경과 일반환경에서 발화한 총 288개의 2음절어를 분석대상으로 하였다. 실험 결과 지속시간과 에너지의 경우는 일반 음성에 비하여 원거리 음성의 첫음절에 대한 둘째음절의 비율이 유의미하게 큰 것으로 나타났다. F0 대역폭의 경우에도 원거리 음성에서의 대역폭이 평이 음성에 비해 큰 값을 보였다. 억양 패턴에 있어서는 원거리 음성의 경우에 둘째음절에 'HL%'의 복합 경계성조가 실현되거나 첫음절에 'L+H' 성조가 실현되기도 하였으며 이 두 가지가 한 단어에 모두 실현되는 경우도 있었다.

This paper investigates the manner in which various. syntactic structures with a single meaning implement a consistent intonational pattern by examining English conditional clauses. In the phonetic experiment, we explore the edge tones in three different syntactic clauses which are semantically interpreted as a single conditional meaning (an if-clause, a clause with no if. and a clause with no if but followed by and) and compare them with the edge tone realized in a clause which is not interpreted as a conditional meaning. We also investigate the tonal differences resulting from the semantic difference between conditional and non-conditional meanings. That is, the conditional clauses expressed in three different syntactic structures show a consistent intonational pattern in their clausefinal boundaries; a rising contour (H- or H%) is realized at the edge of the intermediate phrases (ip) or intonational phrases (IP) in 89% of the if-clauses, 72% of the clauses with no if, and 79% of the clauses with no if but followed by and. On the other hand, 82% of the non-conditional clauses have a falling contour (L- or L-L%) in their final edge. Statistically, Chi-Square tests show that these percentages are all significantly higher, which suggests that a conditional meaning implements a consistent intonational pattern though it is expressed through different syntactic structures. Therefore, the result supports Bolinger's (1989) claim that intonation makes an important contribution to discourse interpretation.
