본 논문에서는 한국어 음성 데이터베이스 구축을 위하여 자동으로 음소경계를 추출하는 자동 음성분할 및 레이블링 시스템을 구현하였다. 기존의 음성분할 및 레이블링 기술을 근간으로 본 시스템을 구현하였으며, 또한 사용자가 자동분할된 음소경계를 확인하여 그 경계를 쉽게 수정할 수 있도록 한글 모티프 환경에서 그래픽 사용자 인터페이스를 개발하였다. 개발된 시스템은 16kHz로 샘플링된 음성을 대상으로 하고 있으며, 레이블링 단위는 45개의 유사음소와 하나의 묵음으로 구성하였다. 그리고 언어학적 정보의 입력방식으로는 음소표기와 철자표기를 사용하였으며, 패턴매칭 방법으로는 hidden Markov model(HMM)을 이용하였다. 개발된 시스템의 각 음소 모델은 수작업에 의해서 음소단위로 분할한 음성학적으로 균형잡힌 445 단어 데이터베이스를 이용해서 훈련되었다. 그리고 본 시스템의 성능평가를 위해 훈련에 사용되지 않는 문장 데이터베이스에 대해서 자동 음성분할 실험을 수행하였다. 실험결과, 수작업에 의해서 분할된 음소경계위치와의 오차가 20ms 이내인 것이 74.7%였으며, 40ms이내에는 92.8%가 포함되었다.

In this research, by yearly subdividing and analyzing the characteristic of the embroidery design according to the garment item with a season the high value added is raised for a differencing and high performance conversion of the high fashion design and there is an object. In 2004, when the total 474 chapter was selected in S/S season till F/W season in 2008 and the embroidery design characteristic according to the kind of an item the analyzing method and statistical method was used. As to the first, and the embroidery design in which it follows of the garment item showed the stylized, and the plant motive of the geometric pattern by an edge and composite arrangement in an one-piece and blouse with the satin stitch and cut work technique. A monotone and the bright tone were used. The second, and the season different difference, the out line stitch, an applique, and the cut work technique S/S season were a feature. A plant, and the animal motive were expressed as the front arrangement and the monotone of the achromatic color appeared. As to F/W season, the long short stitch and satin stitch techniques were with the characteristic profit. The abstract motive showed up as the edge alignment and composite arrangement. And the plain tone and the monotone of the chromatics combination color are used. In the third, and the chronological difference, an applique the embroidery technique showed up in the out line stitch, and 2007 years in 2004 years and 2006 years. And the sentence motive of the animal, and the abstract motive the embroidery motive are embossed in 2005 years and 2006 years in 2008 years.

Purpose: Some of the properties of the prosodic phrasing and some acoustic and phonological effects of contrastive focus on the tonal pattern of Seoul Korean is explored based on a brief experiment of analyzing the fundamental frequency(=FO) contour of the speech of the author. Data Base and Analysis Procedures: The examples were chosen to contain mostly nasal and liquid consonants, since it is difficult to track down the formants in stops and fricatives during their corresponding consonantal intervals and stops may yield an effect of unwanted increase in the FO value due to their burst into the following vowel. All examples were recorded three times and the spectrum of the most stable repetition was generated, from which the FO contour of each sentence was obtained, the peaks with a value higher than 250Hz being interpreted as a high tone (=H). The result is then discussed within the prosodic hierarchy framework of Selkirk (1986) and compared with the tonal pattern of the Northern Kyungsang dialect of Korean reported in Kenstowicz & Sohn (1996). Prosodic Phrasing: In N.K. Korean, H never appears both on the object and on the verb in a neutral sentence, which indicates the object and the verb form a single Phonological Phrase ($={\phi}$), given that there is only one pitch peak for each $={\phi}$. However, Seoul Korean shows that both the object and the verb have H of their own, indicating that they are not contained in one $={\phi}$. This violates the Optimality constraint of Wrap-XP (=Enclose a lexical head and its arguments in one $={\phi}$), while N.K. Korean obeys the constraint by grouping a VP in a single $={\phi}$. This asymmetry can be resolved through a constraint that favors the separate grouping of each lexical category and is ranked higher than Wrap-XP in Seoul Korean but vice versa in N.K. Korean; $Align-x^{lex}$ (=Align the left edge of a lexical category with that of a $={\phi}$). (1) nuna-ka manll-ll mEk-nIn-ta ('sister-NOM garlic-ACC eat-PRES-DECL') a. (LLH) (LLH) (HLL) ----Seoul Korean b. (LLH) (LLL LHL) ----N.K. Korean Focus and Phrasing: Two major effects of contrastive focus on phonological phrasing are found in Seoul Korean: (a) the peak of an Intonatioanl Phrase (=IP) falls on the focused element; and (b) focus has the effect of deleting all the following prosodic structures. A focused element always attracts the peak of IP, showing an increase of approximately 30Hz compared with the peak of a non-focused IP. When a subject is focused, no H appears either on the object or on the verb and a focused object is never followed by a verb with H. The post-focus deletion of prosodic boundaries is forced through the interaction of StressFocus (=If F is a focus and DF is its semantic domain, the highest prominence in DF will be within F) and Rightmost-IP (=The peak of an IP projects from the rightmost $={\phi}$). First Stress-F requires the peak of IP to fall on the focused element. Then to avoid violating Rightmost-IP, all the boundaries after the focused element should delete, minimizing the number of $={\phi}$'s intervening from the right edge of IP. (2) (omitted) Conclusion: In general, there seems to be no direct alignment constraints between the syntactically focused element and the edge of $={\phi}$ determined in phonology; all the alignment effects come from a single requirement that the peak of IP projects from the rightmost $={\phi}$ as proposed in Truckenbrodt (1995).
