Prominence of speech, which is often called 'accent,' affects the fluency of speaking American English greatly. In this paper, we present an accurate prominence detection method that can be utilized in computer-aided language learning (CALL) systems. We employed pitch movement, overall syllable energy, 300-2200 Hz band energy, syllable duration, and spectral and temporal correlation as features to model the prominence of speech. After the features for vowel syllables of speech were extracted, prominent syllables were classified by SVM (Support Vector Machine). To further improve accuracy, the differences in characteristics of neighboring syllables were added as additional features. We also applied a speech recognizer to extract more precise syllable boundaries. The performance of our prominence detector was measured based on the Intonational Variation in English (IViE) speech corpus. We obtained 84.9% accuracy which is about 10% higher than previous research.

Metrical Phonology has asserted that stress shift does not occur in English compounds because it violates the Continuous Column Constraint. Noun phrases, on the other hand, freely allow for stress shift, whereby the preceding stress moves forward to the preceding heavy syllable. This paper hypothesizes that stress does not shift in compounds as opposed to noun phrases and compares their pitch accentual patterns in a phonetic experiment. More specifically, we examined two-word combinations, noun phrases and compounds, whose boundaries involve stress clash and assured that the preceding words involve a heavy syllable ahead of the stress to guarantee the place for a shifting stress. Depending on where the preceding pitch accent is aligned, stress shift is determined. Results show that stress shift occurs in approximately 47% of the noun phrases and 59% of the compounds; therefore, the hypothesis is not borne out. This suggests that the surface representations derived by phonological rules may not be implemented in real utterance but that phonetic forms may be determined by the phonetic constraints. directly operating on human speech.

The metrical structures in orally produced the poetry were generally analyzed by accent, metre and syllable. The purpose of this study is to investigate of metrical structures of Korean modem poetry using computer implemented speech analysis system. Two famous poet's poems confidential talk, Miloe and 'A buddhist dance, Sungmu' were selected for prosodic analysis. The informant is 60 years old professor in major of Korean and French poetry. The syllable structures of poems were analyzed primarily by vowel timbers, which can classified compact and diffuse vowels according to the distance of F2-F1. The perception cues of consonants were analyzed by VOT and tensity features of articulation. Rhythm is classified by dactyl, anapest, trochee, spondee and iambic. As a result, syllable structures of Korean modem poetry were mainly CV and CVC and the reading times of each lines were 3-4sec for 12 and 15 syllables. Main metre of Korean modem poems constructed the Imbic and Anapest. The break of each lines were demarcated by grammatical structure or meaning rather than phonetic structures.

Jindo Ssitgimgut has been known as a funeral ritual for a long time in Korea. However, there is no study for music therapy on anxiety disorder. The aims of this study were to argue that Oral sound Daseureum of Jindo Ssitgimgut may have meaningful effect on anxiety disorder. Jindo Ssitgimgut is literally a cleansing soul. Jindo Ssitgimgut is designated as the Intangible Cultural Property No. 2 by the Korean government. Jindo Ssitgimgut is transmitted from generation to generation, not the descent of God. So, the accent is on art and one's sincere sympathy. So, with careful listening Youtube, this music Daseureum exhibits an exquisite balance between the human voice and the sounds do the instruments. The author think a good combination of his voice, Jing (Korean gong), and Ajaeng (Korean cello) can help with anxiety disorder.

-Nun is generally known as a Topic marker in Korean. However, when it is combined with an accent, it is thought to have a different function, which is alleged to indicate 'contrast' (Kuno 1972). Although the fact that -nun marked item generates some kind of 'contrastive meaning' is uncontroversial, what 'contrast(ive)' means is still unclear. In t his paper, I propose that accented -nun generates two types of implicit propositions in addition to its at-issue meaning. A simple sentence has been repeatedly tested in various models in order to see what type of proposition each proposition corresponds to and it has been concluded that one is presupposition and the other is implicature. This tedious-looking test forms the main part of the first-half of this paper. The presupposition is the essential factor for the -nun marked item to obtain the 'contrastive' meaning. Based on the generation of this presupposition, I argue that -nun works as a contrast operator in a sentence. To illustrate -nun's function as a contrast operator forms the latter part of this paper.

Foraging is a biological process, where a bacterium moves to search for nutriments, and avoids harmful substances. This paper proposes a hybrid approach integrating the bacterial foraging optimization algorithm (BFOA) in a radial basis function neural network, applied to image classification, in order to improve the classification rate and the objective function value. At the beginning, the proposed approach is presented and described. Then its performance is studied with an accent on the variation of the number of bacteria in the population, the number of reproduction steps, the number of elimination-dispersal steps and the number of chemotactic steps of bacteria. By using various values of BFOA parameters, and after different tests, it is found that the proposed hybrid approach is very robust and efficient for several-image classification.

In Korean, it has been well Down that vowel length plays an important role in differentiating word meanings. But the distinction between long and short vowels is often ignored by young generation. The purpose of this paper is to investigate the change in rhythm patterns. In addition, it is also examined whether this change has resulted in the differences in prosodic features between young and old groups. This study is based on H. B. Lee's 'rhythm pattern theory' Based on his assumption, it is suggested that the loss of original vowel length has caused the place of accent to move from the first to the second syllable.

The purpose of this study is to find out the symbolic meaning of interior color a the chosun dynasty's upper class houses, and to review it from a point of view of the Western coloring harmony theory. from this study, the Oriental philosophy, the ideas of Confucianism, and the ethnic traits influenced the interior color of the Chosun Dynasty's upper class houses like an-bang or sarang-bang. The results indicated that main color, auxiliary color, accent color were harmonized with similar harmony by hue and with contrast harmony by value and chroma. Therefore, interior color image of Korean traditional houses should be applied to the various design field as well as modern interior desigv.

In this paper, I examine the phenomenon of English depictive and resultative predications with specific attention given to the relation between accentual focus structure and argument structure. The goal is pursued primarily through a production experiment and analyses to establish the interconnection between focus and argument structure. The central claim is that the resultative predicate forms a complex predicate with a main verb, whereas the depictive predicate behaves as an adjunct in English secondary constructions. The result shows that the relationship between focus and accent depends at least in part on their argument structure, confirming that current focus theories about argument-head and adjunct-head structures in primary predication constructions can be extended to secondary predication constructions.

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.
