This paper presents methods using Gaussian normalization for converting pitch contours based on prosodic phrases along with experimental tests on the Korean database of 16 declarative sentences and the first sentences of the story of 'The Three Little Pigs'. We propose a new conversion method using Gaussian normalization to the pitch deviation of pitch contour subtracted by partial declination lines: by using partial declination lines for each accentual phrase of pitch contour, we avoid the problem that a Gaussian normalization using average values and standard deviations of intonational phrase tends to lose individual local variability and thus cannot modify individual characteristics of pitch contour from a source speaker to a target speaker. From the results of the experiments, we show that this slanted Gaussian normalization using these declination lines subtracted from pitch contour of accentual phrases can modify pitch contour more accurately than other methods using Gaussian normalization.

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 study on the intonational characteristics is concentrated on the lowering of the pitch level that is described as declination and downstep. The Taegu dialect, which has phonological accentual system, has these phonetic characteristics in affirmative sentences or Yes-No Question sentences. But there is the opposite phenomenon in WH question sentences in Taegu dialect. When the accent of interrogative word in the sentence intial position is LHL, intonation pattern shows a continuous upward movement, indicating that intonation pattern of Taegu dialect is influenced by not only grammatical system but also accentual system.

본 연구는 대용량 데이터베이스 분석을 통한 한국어의 운을 특성 규명을 시도하였다. 남녀 화자 1명씩 각각 낭독한 650개의 뉴스기사 문장 (총 1,300 개)은 분절음 레이블링과 운율 레이블링을 한 후, 각 운율단위의 성조유형과 크기, 상위운율단위의 크기와 하위 운율단위 수간의 상관관계, 그리고 강세구의 하강곡선과 상승곡선의 기울기와 F0 값에 대한 비교분석을 수행하였다. 운율단위의 지속시간, 어절수, 음절수와 하위 운율단위의 수는 화자뿐만 아니라 운율단위 위치에 따라서 차이를 보였으며 하위 운율단위의 수는 상위 운율단위의 음절수와 지속시간과 높은 상관관계를 보였다. 강세구 내의 하강곡선의 기울기는 강세구 음절수와 반비례 관계를 보였으며 강세구 첫 성조의 유형에 따라 기울기 값에 차이가 있었다. 이 차이는 고성조로 시작한 강세구 성조의 F0 상승과 성조 간 상승 폭의 차이로 설명할 수 있었다. 강세구 경계의 하강곡선은 일정하면서 강세구 내의 하강곡선에 비해 다소 급격한 기울기를 보였다. 강세구 내의 두 상승곡선은 유사한 기지값을 보였으나 강세구 시작 상승곡선의 F0 변화량이 끝 상승곡선의 F0 변화량보다 크게 나타났다. 그리고 하나의 상승곡선이 강세구를 이루는 L Ha의 경우에는 강세구의 음절수에 반비례 관계를 보였다.

The purpose of this study is to analyse prosodic characteristics of accentual phrases (AP, hereafter) produced by Chinese learners of Korean in Korean text reading. The study is restricted only to the initial APs. Subjects are students who have been studying Korean at a beginner level. The results showed that Chinese learners of Korean tended to make errors in the realization of the tonal patterns of the initial 2 syllables of the initial APs. Also they showed different F0 slopes across the initial and second syllables in the initial APs. Chinese learners of Korean, therefore, need to focus on the prosodic characteristics of the initial 2 syllables of Korean APs to realize fluent Korean intonation.

본 연구는 다문화가정 이주여성의 운율구 경계짓기와 억양패턴에 대한 음향학적인 분석을 통하여 이주여성대상 한국어교육 프로그램 개발의 기초자료를 제공하고자 하였다. 대부분의 운율 특성에서 이주집단이 한국집단과 차이를 보였다. 한국집단은 첫 어절을 100% 강세구로 읽은 반면, 이주집단은 거의 억양구로 실현하였으며 이주여성들은 첫 분절음에 따라 달라지는 강세구의 첫 음조의 패턴 습득이 아직 제대로 이루어지지 않아 한국집단보다 훨씬 다양한 첫 어절의 억양패턴들을 보였다. 몇몇 운율 특성에서는 이주집단 간에도 차이를 보였으며 한국에서의 거주기간이 상대적으로 긴 필리핀집단이 베트남집단에 비해 상대적으로 한국집단에 가까운 특성을 보였다. 문장 내 평균 억양구수는 베트남집단이 필리핀집단보다 많았으며 가부의문문의 문미 경계음조는 필리핀집단은 한국집단처럼 'H%'로만 실현한 반면, 베트남집단은 'H%'뿐만 아니라 'HL%'로도 실현하였다.

The purpose of this paper is to investigate the phonetic characteristics of the 'focus' phrases associated with the particle '-man' in Korean. The particle '-man' is a bound morpheme which, like other postpositions such as the subject marker '-ka' and the object marker '-lil', the so-called 'case markers' in Korean, typically attaches to a noun (phrase). The semantics of '-man' roughly corresponds to that of only, its counterpart in English, and is thus classified as a 'delimiter' (Yang 1973). It is assumed in this paper that '-man', like only in English, should have a 'focus' associated with it (von Stechow 1991, Rooth 1992). In general, '-man' attached phrases get the focus, but sometimes the association is not clear-cut, especially in the cases of emphatic use of '-man' or when the context strongly favors other phrase as the focus (Choe 1996). In this paper, we compare the phonetic characteristics of the '-man' marked phrases with those to which '-ka'/'-lil' is attached, and conclude that the focused '-man' phrases show higher fundamental frequencies than their equally focused 'case' -marked counterparts. However, when the context clearly forces the focus to fall on phrases other than the '-man' or '-ka'/'-lil' attached ones, there is no meaningful difference in fundamental frequency between the '-man' and '-ka'/'-lil' attached phrases. We also compare the phonetic characteristics of the regular use of '-man' with those of the emphatic '-man'. According to our experiments, the emphatic '-man' does not bring forth its phonetic effects, namely, higher fundamental frequencies, on the' -man' attached words or phrases but rather in various other ways such as higher fundamental frequencies in '-man', lengthening of the following word-initial syllable, or the inclusion of the following word in the same accentual phrase. Finally, it is claimed that '-man' associated focus phenomena, especially the emphatic use of '-man', show some typical acoustic characteristics of the other well-known focus phenomena, namely, wh-interrogatives.

This study presents the prosodic characteristics of 'Motherese' and 'Teacherese (child care teacher and kindergarten teacher)'. 21 mothers and 24 teachers spoke to children in the child care center or kindergarten. Children are in their 4;00-6;11. Speech and articulation rate, number of accentual phrases (APs), number of intonational phrases (IPs), pitch-related factors (f0, pitch range, f0 standard deviation), and intonation slope (mean Absolute, f0, q-tone slope) were measured. 2 groups spoke 2 sentential types (interrogative_ alternative question, declarative_ coordinated sentence) in 2 situations (one accompanied with the children, the other done without children, but pretending as if they were in front of the children). The results indicate that teachers show more noticeable prosodic characteristics than mothers do.

This study investigates the degree to which various prosodic cues at the boundaries of prosodic phrases in Korean contribute to word segmentation. Since most phonological words in Korean are produced as one Accentual Phrase (AP), it was hypothesized that the detection of acoustic cues at AP boundaries would facilitate word segmentation. The prosodic characteristics of Korean APs include initial strengthening at the beginning of the phrase and pitch rise and final lengthening at the end. A perception experiment utilizing an artificial language learning paradigm revealed that cues conforming to the aforementioned prosodic characteristics of Korean facilitated listeners' word segmentation. Results also indicated that duration and amplitude cues were more helpful in segmentation than pitch. Nevertheless, results did show that a pitch cue that did not conform to the Korean AP interfered with segmentation.

The current study investigates the degree to which various prosodic cues at the boundaries of a prosodic phrase in Korean (Accentual Phrase) contributed to word segmentation. Since most phonological words in Korean are produced as one AP, it was hypothesized that the detection of acoustic cues at AP boundaries would facilitate word segmentation. The prosodic characteristics of Korean APs include initial strengthening at the beginning of the phrase and pitch rise and final lengthening at the end. A perception experiment revealed that the cues that conform to the above-mentioned prosodic characteristics of Korean facilitated listeners' word segmentation. Results also showed that duration and amplitude cues were more helpful in segmentation than pitch. Further, the results showed that a pitch cue that did not conform to the Korean AP interfered with segmentation.
