The purpose of this study is to investigate the effect of Japanese(L1) on the production of Korean accentual phrases(L2). Korean and Japanese have a similar prosodic structure. But different from Korean, Japanese is a pitch accent language. So each word has its own pitch accent. And pitch accents are maintained in the sentence intonation. This difference will have a negative influence on the production of Korean sentence intonation. For this study 4 Korean natives speakers and 10 advanced Japanese learners of Korean participated in the production test. The material analysed constituted 11 Korean sentences, six of which contain formally identical Sino-Korean and Sino-Japanese words. The results show that the initial pitch pattern of Korean accentual phrases was affected by Japanese pitch accent types and this interference was greater for formally identical Sino-Korean and Sino-Japanese words. But besides initial tones of accentual phrase, some positive interference was observed in the internal tonal pattern of accentual phrase. In the phonetic realization, the internal pitch range and initial pitch rising of accentual phrases was greater for Japanese learners of Korean than native speakers of Korean.

This study examined the effect of vocal loudness on nasalance measures, under the conditions of three sentence patterns (i.e., Oral sentences, Mixed sentences, Nasal sentences). The vocal loudness level was classified into soft voice (55 dB), medium voice (65 dB) and loud voice (75 dB). The participants in the present study were 30 normal adults (male: female =1:1). Kay's Nasometer 6200 was used to measure nasalance and Sound level meter was used to adjust the loudness level. The results of the present study are as follows. Firstly, the change in vocal loudness is in the following. In the Oral sentence stimuli, the loud voice for both male and female showed the highest nasalance degree, and the medium voice the lowest level. In the Mixed and Nasal sentence stimuli, however, male participants showed the highest degree of nasalance in the soft voice, and the lowest degree in the loud voice, and female showed the highest degree of nasalance in the soft voice and the lowest in the medium voice. Secondly, when each subject's nasalance scores were ranked in a ordered manner, noticeable tendency. Lowest nasalance score occurred in the loud voice and the highest nasalance score was recorded in the soft voice during participants' reading of the Nasal sentences. However, it was hard to find such pattern in the Oral sentences. It is assumed that velopharyngeal function could be related to these findings. Furthermore, the findings associated with vocal loudness may have diagnostic as well as clinical implications.

This paper describes a preliminary work on prosody modeling aspect of a text-to-speech system for Thai. Specifically, the model is designed to predict symbolic markers from text (i.e., prosodic phrase boundaries, accent, and intonation boundaries), and then using these markers to generate pitch, intensity, and durational patterns for the synthesis module of the system. In this paper, a novel method for annotating the prosodic structure of Thai sentences based on dependency representation of syntax is presented. The goal of the annotation process is to predict from text the rhythm of the input sentence when spoken according to its intended meaning. The encoding of the prosodic structure is established by minimizing speech disrhythmy while maintaining the congruency with syntax. That is, each word in the sentence is assigned a prosodic feature called strength dynamic which is based on the dependency representation of syntax. The strength dynamics assigned are then used to obtain rhythmic groupings in terms of a phonological unit called foot. Finally, the foot structure is used to predict the durational pattern of the input sentence. The aforementioned process has been tested on a set of ambiguous sentences, which represents various structural ambiguities involving five types of compounds in Thai.

This study investigated the intonation patterns of accentual phrase in Jeju dialect. 9 speakers (Experiment 1) and 6 speakers (Experiment 2) read a carrier sentence '__ youngah miwonghumnida' with a target accentual phrase varying its number of syllables from 1 to 8. The results showed that like Seoul dialect pattern could be the basic pattern of accentual phase in Jeju dialect even though several differences were observed in the realization of each tone: Flat staircase-like tones in L, M, and even in H were often observed, and a very small difference in F0 between intial L and +H was found in many speakers. For some of these differences, this paper tried to give an explanation still in the Intonational Phonology framework. However, introducing M tone as a lexical tone was also suggested as one possible solution. Finally, unlike Seoul dialect, most speakers showed pattern in an accentual phrase beginning with a strong consonant, i.e., aspirated and unaspirated obstruents including /h/ and /s/.

The purpose of this study is to investigate the pattern and characteristics of elementary school teaching and learning processes in science based classes. The study participants' class was recorded in video and instructional conversation transcription. The pattern of the observed class was analyzed using the classification frame suggested by Mogan &Saxton(2006). In result, the questioning for elicit information was most frequent and questioning for shape understanding and the questioning for press for reflection in its priority. In result, the presence of elicited questioning for the attainment of knowledge and understanding is more prominent in science-based classrooms. It was revealed that the participating teachers used the questioning sentence pattern more frequently and the self-sustained inquiry that accelerates creative thinking of the student was lacking. It was discovered that teaching elicited questioning, which accelerates creative thinking, as well as fact confirmation pattern is a necessary element of training for teachers.

In this paper, speech style is divided into two - read speech and dialogue. In the experiment, read speech and dialogue use the same sentence to control discrepancy from different sentence. While the number of AP in read speech is less than in dialogue, the number of IP in read speech is more than in dialogue. The number of syllables which consist of AP is more various in dialogue. Intonational patterns of the first AP in IP make a difference. In dialogue, there is a pattern which has many high tones - LHH. The FO range in dialogue is wider than in read speech.

Studies of prosody and sentence processing have demonstrated that prosodic phrasing can exhibit strong effects on processing decisions in English. In this paper, we tested Korean sentence fragments containing syntactically ambiguous Adj-N1-N2 strings in a cross-modal naming task. Four accentual phrasing patterns were tested: (a) the default phrasing pattern, in which each word forms an accentual phrase; (b) a phrasing biased toward N1 modification; (c) a phrasing biased toward complex-NP modification; and (d) a phrasing used with adjective focus. Patterns (b) and (c) are disambiguating phrasings; the other two are commonly found with both interpretations and are thus ambiguous. The results showed that the naming time of items produced in the prosody contradicting the semantic grouping is significantly longer than that produced in either default or supporting prosody, We claim that, as in English, prosodic information in Korean is parsed into a well-formed prosodic representation during the early stages of processing. The partially constructed prosodic representation produces incremental effects on syntactic and semantic processing decisions and is retained in memory to influence reanalysis decisions.

This study investigates the effect of pitch range reset in Korean listeners' processing of syntactically ambiguous participle structures. Unlike Japanese and English,in Korean, the downtrend or the reset of pitch range does not consistently differentiate Accentual Phrases (AP), a lower level of phrasing, from Intonational Phrases (IP), a higher level of phrasing. Therefore, we explore Korean listeners' comprehension patterns for syntactically ambiguous speech strings varying in 1) the relative height of F0 peaks across prosodic units, and 2) the types of prosodic phrasing, to see whether pitch range reset informs the recovery of syntactic structure even though it is not reflected in the intonational hierarchy in Korean. The results show that the hierarchical level of prosodic phrasing affects the parsing pattern of syntactic ambiguity. The pitch range reset also cued the location of syntactic boundaries, but this effect was confined to phrases across AP.

많은 양의 문서 데이터가 증가됨에 따라 사용자는 해당 문서를 이해하기 위한 요약된 정보를 필요로 한다. 그러나, 기존 문서 요약 연구 방법들은 지나치게 단순한 통계에 의존함으로써 문장의 모호성 및 의미 있는 문장 생성을 위한 다중 문서 요약 연구가 미흡한 실정이다. 본 논문에서는 의미적 연결 관계에 대한 파악 및 불필요한 정보를 처리하기 위한 전처리 과정을 거치며, 어휘 의미 패턴 정보를 기반으로 VAE를 이용하여 문장 간의 의미적 연결성을 높인 다중 문서 요약 기법을 제안하였다. 문장을 이루고 있는 단어 벡터들을 이용하여, 잠재된 변수로 생성된 압축된 정보와 속성 판별기로부터 학습을 한 후 문장을 재구성함으로써 의미적 연결 처리가 자연스러운 요약문을 생성하였다. 제안된 방법과 다른 문서 요약 방법을 비교했을 시 미세하지만 더 향상된 성능을 나타냈으며, 이는 의미적 문장 생성 및 연결성을 높일 수 있음을 증명하였다. 앞으로, 다양한 속성 설정 값을 가지고 실험하여 의미적 연결 관계를 확장할 수 있는 방법을 연구하고자 한다.
