A multimedia Version of ${\ulcorner}Lee-Kim test of Korean Articulation{\lrcorner}$ "Lee-Kim Test of Korean Articulation" consisting of picture test, Sentence test, user's manual and notation, analysis sheets was published in 1990 to serve as a standard tool for testing and analysing the articulation errors of normal and abnormal speakers. It has been found, however that, the picture and sentences test using the printed version of Lee-Kim test of Korean Articulation revealed several limitations, in i, e, a) inefficiency in inducing desirable response from the informants b) lack of concentration and interest on the part of informants c) no consistent way of providing the informant with a clue in case the informant is unfamiliar with the word represented by the picture or the sentence. d) no reliable means for the speech-language pathologist to analyze and evaluate the informant's speech in relation to the standard pronunciation A multimedia version of Lee-Kim Korean articulation Test which features picture and word as well as recorded voice has been developed with a view to eliminating the limitation mentioned above and facilitating the articulation test-with ease and accuracy.

The purpose of this study is to evaluate the association among articulation rate, speech intelligibility and working memory in children with dysarthria. Two subject groups of 11 spastic and 11 flaccid dysarthria, respectively, aged between 8 and 17 years of age participated in this study. All participants were administered the following tests: K-WISC III PIQ test, speech intelligibility, working memory and articulation rate. Group differences were compared by an independent t-test. Pearson correlation were computed between all measures. The results of this study are as follows: First, articulation rate and intelligibility were significantly lower for the spastic dysarthria than for the flaccid dysarthria. Second, there was a significant correlation between articulation rate and intelligibility in children with flaccid dysarthria. Lastly, there was no significant correlation between articulation rate and working memory in both groups. The results suggest that articulation rate is not necessarily accompanied by working memory capacity in children with dysarthria, and there are differences in the effect of articulation rate on intelligibility depending on the type of dysarthria.

본 연구의 목적은 L2KSC(외국어로서의 한국어 음성 말뭉치)의 한국어 부분에서 한국어 낭독과 자유 발화를 분석하여 음성 유형의 운율 차이를 명확히 하는 것이다. 이를 위해 문장의 조음 길이, 조음 속도, 한 문장 내 휴지 길이 및 휴지 빈도, 문장 F0값을 변수로 설정하고 통계적 방법론(t-검정, 상관 분석, 회귀 분석)을 통해 분석하였다. 실험결과, 낭독과 자유 발화는 각 문장을 구성하는 운율구 형태가 구조적으로 달랐는데 각 발화 유형을 구별하는 운율적 요소로는 조음 길이, 휴지 길이, 휴지 빈도로 나타났다. 통계적 결과에서는 낭독 발화는 조음 속도와 조음 길이의 상관관계가 가장 높았는데, 이는 주어진 문장이 길수록 화자가 더 빨리 말하는 것을 설명하였다. 그러나 자유 발화에서는 문장의 조음 길이와 휴지 빈도 사이의 관계가 높았다. 전반적으로 자유 발화에서는 문장을 만들기 위해 짧은 억양구가 지속적으로 만들어지는데, 그런 이유로 더 많은 휴지가 발생하여 문장이 더 길어지는 것으로 나타났다.

There is close relationship between intraoral structural anomaly and speech- functional problem. Patient with cleft palate patients & ankyloglossia is a typical example, patients with structural anomaly is repaired toward normal structure by operation. Ankyloglossia may cause functional limitation even after adequate surgical treatment speech disorders being one of them. Interindividually, they vary a lot, showing typical articulation specifics. The objective of this study was to evaluate and compare speech for children with ankyloglossia and general public, to determine whether ankyloglossia is associated with articulation problem. We wanted to present criteria for indication of frenectomy. The group of subject is composed of 10 childrens with ankyloglossia and articulation problem, visited the Oral and Maxillofacial surgical unit, dental hospital, Chonbuk university. The average age is 5 Y 7M, M : F ratio is 8 : 2 at the time of speech test. Control group is composed of 10 members without oral structural anomaly. The average age is 5 Y 10M, M : F ratio is 3 : 7 at the time of speech test. Outcomes were measured the PPVT(Peabody Picture Vocabulary Test), PCAT(Picture Consonant Articulation Test), Nasometer II test result obtained each group, statistically measured by Mann-whitney's U Test. There was no difference for 'chronological age-age equivalent' between two group. There was significant difference for 'consonant accuracy' between two group, showed more lower scores in subject group. There was more 'consonant error' in subject group, mostly showed/1/,/s/. A major modality of 'consonant error' was mostly distortion and replacement. There was no significant difference between two group for nasality.

The purpose of this study is to examine the improvement effect of articulation of the fricative consonant /s/(ㅅ), when applying the Articulation Modification Program (AMP) to hearing disordered students. Three hearing disordered students were selected for this study by the consonant picture and Korean Articulation Sentence tests. They have no defect in their emotion, behavior and sight. This program applied the multiple baseline design across subjects to examine the improvement effect of articulation of fricative consonant /s/(ㅅ). Also I designed th$\sim$s program with an advanced pre-test and post-test in order to research the improvement difference of articulation by articulation position and language unit. It was executed 32 sessions over three months, four sessions a week, one session taking forty minutes. The results according to the study subject are as follow; First, as result of AMP, articulation of all students was developed after applying this program. Second, as result of AMP, articulation in fore-word was one-hundred percent efficiency and articulation in middle-word was 97.7% efficiency by position. Third, as result of AMP, articulation in the word reached 98.7% efficiency, in phrase 97.7% efficiency, in the sentence 97.7% efficiency and in the story was 98.3% efficiency by language unit.

Background and Objectives : Children with cleft palate children may be imparied in articulation and resonance. This study examined the phonological process usage of 3-, 4- and 5- year old children with cleft palate. Materials and Method : Twenty seven children with cleft palat participated 3-, 4- and 5-year old children with cleft palate. The authors performed speech evaluation using picture consonants test for children with cleft palate. Percentage of consonants correct(PCC), mean value of each phoneme depends on articulation site and manner were evaluated. Results : In place of articulation, ommission of velar consonants were the most frequent. In manner of articulation, ommission of nasal consonants were the most frequent. Backing, glottal stop, was the most prominent phonological process children with cleft palate. Conclusion : These results may indicate that articulation disorder with cleft palate. and other articulation disorders differences should be considered in the interpretation of speech evaluations.

In this paper, we examine the method of articulation test which is effective in evaluating the speech quality in mobile communication. The korean monosyllable lists for articulation test are developed based upon the frequency of occurrence of korean monosyllables used under natural environment. The monosyllable articulation lists are recorded through the public switch telecommunication network(PSTN) and mobile telecommunication system. The recorded lists are presented to the listeners through the headphone in order to deep the listening conditions equal. It is showen that the articulation lists perform well under different signal-to-noise ratios and the restriction of some frequency ranges. Some articulation scores obtained within the PSTN and between the mobile communication system and PSTN are presented.

This paper investigated the effects of frequency band limitation on perceptual characteristics of Korean consonants. Monosyllabic speech (144 syllables of CV type, 56 syllables of VC type, 8 syllables of V type) produced by two announcers were low- and high-pass filtered with cutoff frequencies ranging from 300 to 5000 Hz. Six listeners with normal hearing performed perception test by types of filter and cutoff frequencies. We reported phoneme recognition rates and types of perception error of band-limited Korean consonants to examine how frequency distortion in the process of speech transmission affect listener's perception. The results showed that recognition rates varied with the following factors: position in a syllable, manner of articulation, place of articulation, and phonation types. Consonants in the final position were stronger to the frequency band limitation than those in the initial position. Fricatives and Affricates are stronger than stops. Fortis consonants were less stronger than their lenis or aspirated counterparts. Types of perception error also varied depending on such factors as consonant's place of articulation: In case of bilabial stops, they were perceived as alveolar stops with while in cases of alveolar and velar stops, there were changes in phonation types without any change in the place of articulation.
