In the previous studies, some characteristics of flaccid dysarthria patients have been studied mainly in two aspects: their difficulties in articulation and their metrical dysfunction. Therapeutic research on the articulation impediment of the patients have been carried out extensively (Yorkston, 1981). However, their phonetic characteristics have been less well-studied. The aim of this paper is to measure and describe some phonetic differences between the normal speaker group (six speakers) and the flaccid dysarthria patient group (six speakers in three different degreed of severity). Two types of short sentences comprising of subject-object-verb, i.e. declarative and yes-no question sentences, were recorded to investigate some phonetic characteristics of these two groups of speakers. The two groups (normal group vs. patient group) show differences in yes-no question boundary tone (H% vs. HL%), pitch range (wide vs. narrow), duration (short vs. long) and intensity (strong vs. weak) of sentence final verb endings in Korean.

The purpose of this study is to examine the prosodic pattern of the children with high functioning autism spectrum disorder(HFASD) according to sentence type. The participants were 18 children aged from 7 - 9 years; 9 children with HFASD and 9 typical development children(TD) of the same chronological age with HFASD children. Sentence reading tasks were conducted in this study. Seven interrogative sentences and 7 declarative sentences were presented to the participants and were asked to read the sentences three times. Mean values of F0, F0 range, intensity, speech rate and pitch contour were measured for each sentence. The results showed that for F0 range, significant main effect and interaction effect were observed in the subject group and sentence type. There were significant differences in intensity, mean F0, speech rate, pitch contour across sentence types. The results of this study indicated that HFASD showed no difference in intonation across sentence types. Speakers' intention may have a negative effect on pragmatic aspects. These results suggest that the assessment and intervention of prosody be important for HFASD.

This study aimed to establish characteristics related to voice and speech through the natural base frequency analysis of esophagus vocalization. In the study, 8 subjects were selected for esophagus vocals, and 10 other subjects were selected for a control group. MDVP(Multi-dimensional Voice Program, Model 4800, USA, 2001), Multi Speech(Model 3700, Kaypantax, USA, 2008) were used as experiment equipment. The speech samples selected for evaluation were vowels and sentences (both declarative and interrogative). For acoustic analysis, the intonation form of fo, jitter, energy, shimmer, HNR, and intonation patterns of the speech sample were measured. The results were as follows: First, the natural intrinsic frequency of extended vowels in the esophagus vocal group was lower than the frequency in the normal vocal group. In particular, the intrinsic frequency difference for high vowel /i/ was much greater than the frequency difference for low vowel /a/. Second, the jitter values of the esophagus vocal group were higher than the control group. In particular, there was a large difference between the jitter values for /a/ and /i/, with the jitter values being highest for /i/. Third, there was no significant difference in vocal strength between the esophagus vocal patient group and the control group. Fourth, the shimmer values of the voices in the esophagus vocal group were higher than shimmer values in the control group. In particular, there was a large difference in shimmer values for low vowel /a/. Fifth, the HNR values of the esophagus vocal group were showed significantly lower than the control group. In particular, the largest difference in HNR values between the two groups was for high vowel /i/. Sixth, the pitch contours of interrogative and declarative sentences of the esophagus vocal patient group showed a different form or only had with small differences compared to the pitch contours of the normal vocal group, thus presenting an inconsistent pattern.

This study aims to examine whether the fundamental frequency (F0) varies depending on languages or distinguishes between L1 (first language) and L2 (second language) speech and whether the type of materials which vary in control of consonant voicing affects the use of F0-especially, mean F0. For this purpose, we compared productions of two languages produced by Korean L2 learners of English to those of Korean-English bilingual speakers. Twelve Korean L2 speakers of English and twelve Korean-English bilingual speakers participated in this study. The subjects read aloud 22 declarative sentences-balanced and unbalanced-once in English and once in Korean. Mean F0 of Korean was higher than that of English for both speaker groups, and the difference in the value of mean F0 between the Korean and English sentences was different depending on the type of materials that the participants read. With regard to F0 range, the L2 speakers had a larger F0 range in English than in Korean; however, the effect of language on F0 range was not statistically significant for the bilingual speakers. These results indicate that language-specific properties may affect the use of F0, in particular, mean F0.

This paper aims to discuss the effects of learning how to write English interrogative sentences. 122 students who participated in the study learned basic structural components of English questions and practiced writing questions by inversing the subject and the verb in a given declarative sentence. The participants were divided into two groups: Group 1 which was given a brief explanation of interrogative structures and practices, and Group 2 which was given the same explanation and practices in addition to an assignment for which they had to make one or two comprehension questions based on reading a passage. For the pre-tests and the post-tests, they took a TOEIC reading test with 40 questions and a structure test with 25 questions. The results of the tests show that both groups improved significantly in the two post-tests, benefiting from this learning method. However, the additional treatment for Group 2 did not seem to be highly effective. In the questionnaire survey, the participants think that the method of learning English questions has helped them better understand English grammar as well as interrogative structures. The participants were also divided into three different levels: high, intermediate, and low. The intermediate level group students benefited most from learning writing questions as the results of the post-test of the 25-questions test and the final exam of the course show.

Despite the fact that the phenomenal success of the classical model in phonology in terms of a small set of binary atomic primitives has encouraged the use of criterical features in the characterization of syntactic and semantic categories, cognitive linguists have recently found many evidences against it and proposed a valid alternative like prototype approach to classical model of linguistic categorization. In this paper the examples with prototype effects are shown in phonology, morphology, and syntax. In phonology there is no clear-cut borderline in initial sounds such as / r, m, n, v, ${\eth}$, z, w. j, b. d, g / and between vowels and consonants. In morphology family resemblance is shown between strong verbs and past tenses. In syntax there is no borderline among various kinds of sentences such as declarative, command, WH-question, yes-no question, etc.

This study details the history and characteristics of consumption values, text style analyses, and appeal types expressed in magazine commercials from 1955 to 2008. This study analyzes the level of the social structure of commercial expression for each period. Consumption values based on the categories of consumption values by Sheth (1991) were classified through a total commercials analysis. Analyses on closing types of sentences, types of sentences, and rhetorical figures were executed focusing on headline text and text style. Appealing types were composed of rational, emotional, and ethical appeals. For analysis, the crosstab analysis and chi-square test of SPSS are used. The results are as follow. Seven values were constructed, functional value, social value, emotional value, conditional value, epistemic value, fashionable value, and indistinct value. The ratio of emotional value was the highest and functional value, epistemic value conditional value, fashionable value, social value, and indistinct value followed. The emotional value social value, conditional value, fashionable value, and epistemic value that focused on the emotion of consumers increased, while the functional value decreased. Sentences that use narrative styles, hyperboles, and metaphors that increased the interest of readers were dominantly used in the headline texts. For sentence expression, a declarative sentence in a sentence type, exciting curiosity in the expression method where hyperbole and figures of speech in rhetorical expressions are used most often. Emotional appeal was used almost twice more than the reasonable appeal for appeal types of the total commercial. The lower level of reasonable appeal is information that provides the product function. Interest and expression (such as pleasure and achievement) were used most often for emotional appeal. These results show that the most important issue is the emotional value in consumption in understanding the consumer. Marketing managers should also be aware of the functional value as well as an emotional value.

본 연구의 목적은 한국인 영어 학습자가 영어문장을 읽을 때 어떠한 초분절 요소가 영어 원어민 화자에 가깝게 구현되는데 영향을 미치는지를 밝혀 영어 발음교육에 도움이 되고자 하는 것이다. 본 연구에서는 연구대상자를 중학생 영어학습자로 선택하고, 다양한 유형의 문장(평서문, 의문문, 명령문, 감탄문)과 음절수로 연구 자료를 구성하였다. 이들 영어 문장 발화의 분석대상으로는 초분절 요소 중 발화속도, 휴지빈도, 휴지길이, F0 범위, 리듬을 이용하였고 음성분석 결과는 평균분석, 상관분석 및 회귀분석을 실시하였다. 그 결과, 발화속도, 휴지빈도, 휴지길이, F0 범위가 유창성 등급 평가에 영향을 미친다는 결과를 얻었다. 모든 초분절 요소와 유창성 등급 간의 회귀분석에서는 유창성 등급에 영향을 미치는 초분절 요소는 발화속도와 F0 범위이다. 리듬은 유창성 등급과의 관계에서 통계적으로 유의미하지 않았다. 따라서, 영어 발음교육을 할 때 발화속도를 높이고, F0 범위를 크게 하도록 교육하는 것이 필요하다. 또한, 발화시 휴지개수와 휴지시간을 줄이도록 하는 교육이 유창성을 높이는데 도움이 된다. 문장유형을 분류하여 분석한 결과, 감탄문의 경우 다른 문장유형에 비해 발화속도가 더 빠르고, 휴지빈도는 더 적고, 휴지길이는 더 짧으며, 리듬값은 더 높았다.

본 논문에서는 한국어 문장 유형을 자동으로 분류하는 방법을 제안하고 한국어-수화 변환과 한국어 음성 합성 분야에서 문장 유형 정보가 자연스러운 수화 표현과 음성 표현을 생성하는데 이용되는 과정을 보인다. 한국어에서 문장 유형은 크게 평서문, 명령문, 청유문, 의문문, 감탄문의 다섯 가지로 분류되는데, 기존의 방법으로는 대화체 문장에서 동일한 문장이 여러 가지 유형으로 해석되는 중의성의 문제가 발생한다. 본 논문에서는 문장 내에서 형태소 및 구문단위의 다양한 단서들을 활용하여 이를 해결하는 방법을 제안하며, 실험 결과 본 논문에서 제시한 문장 유형 분류 시스템이 만족할 만한 성능을 보이는 것을 확인하였다. 이를 이용하여 한국어-수화 변환 시스템에서 문장 유형에 따라 수화의 비수지신호가 다르게 표현되는 현상을 처리하는 과정과 한국어 음성 합성 시스템에서 문장 유형에 따라 문장의 문미 억양이 변하는 현상을 처리하는 과정을 제시한다. 문장 유형 정보를 음성 합성과 수화 자동 생성에 이용하는 것은 기존에는 연구되지 않았던 방법으로, 좀 더 자연스러운 음성과 수화 표현을 생성하는데 중요한 역할을 할 것으로 기대한다.
