In this study, remote articulation training system which connects the hearing disabled trainee and the speech therapist via B-ISDN is introduced. The hearing disabled does not have the hearing feedback of his own pronunciation, and the chance of watching his speech organs' movement trajectory will offer him the self-training of articulation. So the system has two purposes of self articulation training and trainer's on-line checking in remote place. We estimate the vocal tract articulatory movements from the speech signal using inverse modelling and display the movement trajectory on the sideview of human face graphically. The trajectories of trainees' articulation is displayed along with the reference trajectories, so the trainee can control his articulating to make the two trajectories overlapped. For on-line communication and ckecking training record, the system has the function of video conferencing and transferring articulatory data.

음성은 개별 조음 기관(입술, 혓끝, 혓몸, 연구개, 성문)에서 일어나는 협착 운동들의 시공간적 협응 구조라 할 수 있다. 다른 인간의 운동(예: 잡기)과 마찬가지로 각각의 협착 운동은 언어학적으로 의미 있는 task이며, 각 task는 그것과 관계된 기본 요소들의 시너지에 의해 수행된다. 본 연구는 이러한 음성 task가 어떻게 기본 요소들인 joint와 동역학적으로 연계될 수 있는지를 로보틱스의 관점에서 논의하고자 한다. 나아가 로보틱스의 기본 원리를 음성과학 분야에 소개함으로써 운동으로서의 음성이 어떻게 발화되는지에 대한 더 깊은 이해를 가능케 하고, 실제 인간의 조음을 모방한 말하는 기계를 구현하는 데 필요한 이론적 토대를 제공하고자 한다.

The purpose of our study was to provide effective speech evaluation items examining the variables of speech that successfully predict the speech intelligibility in CP children. The subjects were 55 children with spastic type cerebral palsy. As for the speech evaluation, we performed a speech subsystem evaluation and a speech intelligibility test. The results of the study are as follows. The evaluation task for the speech subsystems consisted of 48 task items within an observational evaluation stage and three levels of severity. The levels showed correlations with gross motor functions, fine motor functions, and age. Second, the evaluation items for the speech subsystems were rearranged into seven factors. Third, 34 out of 48 task items that positively correlated with the syllable intelligibility rating were as follows. There were four items in the observational evaluation stage. Among the nonverbal articulatory function evaluation items, there were 11 items in level one. There were 12 items in level two. In level three there were eight items. Fourth, there were 23 items among the 48 evaluation tasks that correlated with the sentence intelligibility rating. There was one item in the observational evaluation stage which was in the articulatory structure evaluation task. In level one there were six items. In level two, there were eight items. In level three, there was a total number of eight items. Fifth, there was a total number of 14 items that influenced the syllable intelligibility rating. Sixth, there was a total number of 13 items that influenced the syllable intelligibility rating. According to the results above, the variables that influenced the speech intelligibility of CP children among the articulatory function tasks were in the respiratory function task, phonatory function task, and lip and chin related tasks. We did not find any correlation for the tongue function. The results of our study could be applied to speech evaluation, setting therapy goals, and evaluating the degree of progression in children with CP. We only studied children with the spastic type of cerebral palsy, and there were a small number of severe degree CP children compared to those with a moderate degree of CP. Therefore, when evaluating children with other degrees of severity, we may have to take their characteristics more into account. Further study on speech evaluation variables in relation to the severity of the speech intelligibility and different types of cerebral palsy may be necessary.

Second language learners' variable degree of production difficulty according to the cluster type has previously been accounted for in terms of sonority distance between adjacent segments. As an alternative to this previous model, I propose a Phonetically Based Consonant Cluster Acquisition Model (PCCAM) in which consonant cluster markedness is defined based on the articulatory and perceptual factors associated with each consonant sequence. The validity of PCCAM has been tested through Korean speakers' production of English consonant clusters.

This paper attempts to acoustically examine the place of articulation of Korean affricates. In order to pursue an acoustic analysis of where Korean affricates are articulated, we resort to LPC spectra of the Korean plain affricate /c/ in intervocalic position, based on theoretical assumptions (e.g., Stevens 1993a), and compare the data to that of the Korean alveolar consonants /t, s/ in the same context. Our phonetic results show that in intervocalic position, the Korean plain affricate is alveolar just like the Korean alveolar consonants /t, s/, supporting the articulatory studies of $Skali{\check{c}}kov{\acute{a}}$ (1960) and Kim (1997).

최근 많은 음성검사기들의 개발에 의해 발성의 원리에 대한 많은 연구가 진행되었고 실제 임상에 이용되므로써 각종 음성질환의 기전을 연구하는데 많은 도움이 되어왔다. 그중 전기 glottogra-phy(EGG)는 값싸고 완전히 noninvasive한 음성검사기로서 각종 음성질환에 대해 진단, 치료 및 예후판정 등에 이용되어왔으며, 또한 정상 발성시의 성대진동 기전에 대해 연구되어왔다. 그러나 판독하는데 있어 실제 많은 논란이 있는데 이러한 논란은 복잡한 성 대진동 양상에 의해 생기는 것으로 EGG에 의한 양측 성대 사이의 전기 저항도는 실제 성문의 열림의 정도를 의미하는 것이 아니라 성문접촉율을 의미하기 때문이다.

본 논문에서는 화자의 입모양의 변화를 분석하여 발음된 음성을 인식하는 방법에 관하여 연구하였다. 입모양 변화를 나타내는 특징벡터의 서로 다른 선택이 인식성능에 미치는 영향을 비교 분석하였다. 특징벡터로서는 ASM(Active Shape Model) 파라메터와 Acticulatory 파라메터를 특별히 선택하여 인식성능을 비교하였다. 모의실험 결과, Articulatory 파라메터를 사용하는 것이 인식성능도 더 우수하고 계산량도 더 적음을 확인할 수 있었다.

Objectives: This case study evaluated the effectiveness of Chengsimyeonja-tang-gamibang (Gamicheongsim-tang and Cheongsimsunhwal-tang) in a patient with a pontine hemorrhage and quadriparesis, dysarthria, and dysphagia. Methods: A patient diagnosed with a pontine hemorrhage was treated with Chengsimyeonja-tang-gamibang (Gamicheongsim-tang and Cheongsimsunhwal-tang) acupuncture, and moxibustion. The manual muscle test (MMT), modified Barthel index (MBI), National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS), Mini Mental State Examination-Korea (MMSE-K), and Articulatory Functional Ability of Achievement Scale were administered. Results: Improvements in the MMT, MBI, NIHSS, mRS, and K-MMSE were observed after the treatment. The MMT grade increased from Rt. 3/3- and Lt. 3/3- pretreatment to Rt. 4/4 and Lt. 4+/4+ post-treatment. The MBI increased from 10 to 50 post-treatment. The NIHSS decreased from 24 to 6 post-treatment, and the mRS fell from 5 to 4 post-treatment. Finally, the MMSE-K increased from 0 to 24 post-treatment. The Articulatory Functional Ability of Achievement Scale also improved. Conclusion: This study shows that Chengsimyeonja-tang-gamibang can be used to treat the symptoms of patients with a pontine hemorrhage.

한국어 단어의 글자 수, 받침의 수와 위치, 합성어 여부가 기억폭에 미치는 효과를 검증하였다. 그 결과, 전반적으로 글자가 많은 단어일수록 기억폭이 작았으며, 두 글자 단어들에서 받침이 많을수록 기억폭이 더 작았고(기억폭에 대한 받침효과), 합성어보다 단일어의 기억폭이 더 컸다. 단어당 읽기 속도를 측정한 결과, 글자가 많은 단어일수록 속도가 느렸지만, 두 글자 단어들에서 뒷받침단어의 읽기 속도가 받침없는 단어, 앞받침단어 및 양받침단어보다 더 빨랐고(읽기 속도에 대한 말미 받침효과), 합성어보다 단일어의 읽기 속도가 더 빨랐다. 기억폭과 읽기 속도간에 관찰된 이러한 관계는 단어길이효과에 대한 음운루프설명과 잘 부합되지 않으며, 기억폭이 음운정보 뿐만 아니라 시각적 캐시에 표상되는 철자 정보의 영향을 받는다는 설명을 지지해준다.

Purpose: This study investigates Korean speech sound development, including articulatory error patterns, among the Japanese-Korean children whose mothers are Japanese immigrants to Korea. Methods: The subjects were 28 Japanese-Korean children with normal development born to Japanese women immigrants who lived in Jeonbuk province, Korea. They were assessed through Computerized Speech Lab 4500. The control group consisted of 15 Korean children who lived in the same area. Results: The values of the voice onset time of consonants /$p^h$/, /t/, /$t^h$/, and/$k^*$/ among the children were prolonged. The children replaced the lenis sounds with aspirated or fortis sounds rather than replacing the fortis sounds with lenis or aspirated sounds, which are typical among Japanese immigrants. The children showed numerous articulatory errors for /c/ and /I/ sounds (similar to Koreans) rather than errors on /p/ sounds, which are more frequent among Japanese immigrants. The vowel formants of the children showed a significantly prolonged vowel /o/ as compared to that of Korean children ($P$<0.05). The Japanese immigrants and their children showed a similar substitution /n/ for /ɧ/ [Japanese immigrants (62.5%) vs Japanese-Korean children (14.3%)], which is rarely seen among Koreans. Conclusion: The findings suggest that Korean speech sound development among Japanese-Korean children is influenced not only by the Korean language environment but also by their maternal language. Therefore, appropriate language education programs may be warranted not only or immigrant women but also for their children.
