This study attempted to reveal the physiologic etiology or related factors associated with speech processing by comparing the compensation ability in speech motor control in children with and without articulation disorders. Subjects were 35 children with articulation disorder and 35 children without articulation disorder whose age ranged from 5 to 6 years. They were asked to rapidly repeat /$p^ha$/, /$t^ha$/, /$k^ha$/, /$p^hat^hak^ha$/ diadochokinetic movement while mandible was free and mandible was stabilized with bite block. The results showed that children with articulation disorder revealed significantly greater difference in elapsed time for diadochokinetic movement between mandible free and stabilized state compared to the without articulation disorder group. But the correlation between the percentage of consonants correct and the compensation ability in speech motor control in the articulation disorder group was irrelevant. These results point out to the fact that children with articulation disorder have poor compensation ability in speech motor control compared to the children without articulation disorder. On the other hand, the poor ability does not have any relation with the severity of articulation disorder. These results suggest either general or individual characteristics of children with articulation disorder.

This study investigated final consonant error characteristics at word-medial position in children with functional articulation disorder. Data was collected from 11 children with functional articulation and 11 normal children, ages 4 to 5. The speech samples were collected from a naming test. Seventy-five words with every possible bi-consonants matrix at the word-medial position were used. The results of this study were as follows : First, percentage of correct word-medial final consonants of functional articulation disorder was lower than normal children. Second, there were significant differences between two groups in omission, substitution and assimilation error. Children with functional articulation disorder showed a high frequency of omission and regressive assimilation error, especially alveolarization in regressive assimilation error most. However, normal children showed a high frequency of regressive assimilation error, especially bilabialization in regressive assimilation error most. Finally, the results of error analysis according to articulation manner, articulation place and phonation type of consonants of initial consonant at word-medial, both functional articulation disorder and normal children showed a high error rate in stop sound-stop sound condition. The error rate of final consonant at word-medial position was high when initial consonant at word-medial position was alveolar sound and alveopalatal sound. Futhermore, when initial sounds were fortis and aspirated sounds, more errors occurred than linis sound was initial sound. The results of this study provided practical error characteristics of final consonant at word-medial position in children with speech sound disorder.

The purpose of this study was to compare the acoustic properties of fricatives, /ㅅ, ㅆ/ produced by children with functional articulation disorder and normal children (N=20, aged 6-7). All subjects showed significant differences in both the length of friction intervals and breathing intervals of fricatives according to the changes in the environment presented within each group. However, there is a difference in the extent of variation in length between the two groups. This means that children with functional articulation disorder have greater difficulty in adjusting fricative noises according to changes in the CV VCV environment than normal children.

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.

Articulation disorders are characterized by an inability to achieve clear pronunciation due to misuse of the articulators. In this paper, a method of detecting such disorders by comparing to the standard pronunciations is proposed. This method defines the standard pronunciations from the speeches of normal children by clustering them with three features which are the Linear Predictive Cepstral Coefficient (LPCC), the Mel-Frequency Cepstral Coefficient (MFCC), and the Relative Spectral Analysis Perceptual Linear Prediction (RASTA-PLP). By calculating the distance between the centroid of the standard pronunciation and the inputted pronunciation, disordered speech whose features locates outside the cluster is detected. 89 children (58 of normal children and 31 of children with disorders) were recruited. 35 U-TAP test words were selected and each word's standard pronunciation is made from normal children and compared to each pronunciation of children with disorders. In the experiments, the pronunciations with disorders were successfully distinguished from the standard pronunciations.

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.

We report the clinical treatment experience of a case with severe lateralization articulation disorder especially in /ㅅ/, who was treated with using a dynamic palatogram. The patient was 16-year-old male patient and he was taken several attempts of traditional speech therapy without improvement The authors tried to treat him with newly designed dynamic palatogram for two period with good results. We are going to review brief clinical experience with the patient and discuss the effectiveness and indications of the dynamic palatogram. In this study, we can summarize the effect of treatment as follows; Lateralization of the /ㅅ/ was improved markedly with using the dynamic palatogram, and we thought the improvement was achieved mainly by visual feedback control.

General characteristics of speech in deft palate patients are hypemasality and articulation disorder, which are affected by velopharyngeal inadequacy(VPI). 17 subjects with a chief complaint of 'nasal sounds and inaccurate pronunciation' underwent a speech-language evaluation before and after pharyngoplasty. Hypemasality and obligatory articulation errors were improved but compensatory articulation errors remained after pharyngoplasty. Above mentioned results indicate that resonance may be normal or improved following successful surgical management of VPI but, compensatory articulation errors will still persist. The separate recognition of hypemasality, compensatory and obligatory articulation errors in deft palate patients is important in determining the timing of therapy and selection of appropriate targets in therapy.

Objective : The purpose of this paper is to report the improvements of a patient who has suffered from aftereffects following stroke such as dysgraphia and articulation disorder, which is treated by herbal medication based on Shanghanlun disease pattern identification diagnostic system. Methods : According to 'Disease Pattern Identification Diagnostic System based on Shanghanlun Provisions', the patient was diagnosed as Taeyang-byung Gyeolhyung and number 138 provision, and was administered Sohamhyung-tang for 90 days. We recorded the progress of improvements based on the patient's statement and documented the patient's writing Results : The patient can write the letters such as U, 2, ㄹ,ㅇ more clearly and become confident on both writing and speaking. Conclusions : This case shows the effects of Sohamhyung-tang on aftereffects following stroke such as dysgraphia and articulation disorder. It was induced according to the 'Disease Pattern Identification Diagnostic System based on Shanghanlun Provisions' so that it suggest a potential interpretation, which is different with it of the text books Herbal Formula Science and Sanghallonjeonghae, on the provision no. 138. Also the usage of Sohamhyung-tang in this case may support the way far from the diagnosis of oriental neurological medicine, which explain the pathology of stroke as fire-heat(火熱), dampness-phlegm(濕痰), static blood(瘀血) and dual deficiency of qi and blood(氣血兩虛).
