The purpose of this study was to compare phonological awareness ability of students with Down Syndrome(DS) and typically developing children(TD). TD and DS were equal the reading abilities(reading recognition). The subject were 10 DS and 10 TD, and were examined by test of phonological awareness. The test of phonological awareness was composed according to phonological units(word, syllable, phoneme) and task types(deletion, discrimination, blending). The results obtained in this study were as follows: The total score of phonological awareness ability of DS were significantly lower than TD. And the score of phonological awareness ability according to phonological units and task types were significantly lower than TD. But both DS and TD performed better on phonological deletion and blending task than discrimination. TD and DS represented different correlation between task types and phonological units. This means that TD performed better on all types of tasks and phonological units than DS.

The present study aimed to determine the phonological errors of children in Korean-Vietnamese speaking multicultural families through comparison analyses with those of Korean monolingual peers with phonological disorders. The subjects were 38 children aged about 4-6 years. To examine phonological errors, the Urimal Test of Articulation and Phonation (words) was used. Performances were analyzed by frequency. The results showed some differences between the two groups. There was a tendency for children in Korean-Vietnamese speaking multicultural families to show a higher frequency of phonological errors than Korean monolingual children with phonological disorders. However, the former showed lower error percentages in a few error patterns than the latter such as syllable final consonant deletion, showing similar patterns to those of the normal children. They also showed very unique error patterns such as the highest error percentage in palatal affricates. It remains to be seen if these error patterns are just delay in acquisition or phonological disorders.

The purpose of this study was to identify the characteristics of the phonological discrimination ability and phonological working memory of 10 typically developing children aged 4, and 10 other children with Specific Language Impairments whose language age is similar. In orders to compare their phonological discrimination ability among phonological awareness, discrimination tasks were conducted at the syllable and phoneme levels. Also, in order to compare their phonological working memory, the subjects repeated nonsense syllables. The research results may be summarized as follows: First, the children with Specific Language Impairments demonstrated a lower performance than the typically developing children in phonological discrimination ability at both syllable and phoneme levels, and the difference between the groups was statistically significant. Second, the children with Specific Language Impairments exhibited a lower phonological working memory performance in all syllables compared with normal children. Although there was no significant difference in 2 and 3 syllables, a significant difference appeared as the length of the syllables became longer from 4 to 6 syllables. It is deemed necessary to conduct research into qualitative and quantitative differences through an formal assessment of the phonological awareness and phonological working memory of children with Specific Language Impairments.

The purpose of this study was to investigate the phonological error patterns of korean children with and without specific phonological disorders(SPD). In this study, 29 normally developing children and 10 SPD children were involved. The children were matched the percentage of consonants correct(PCC). 22 picture cards were used to elicit korean consonants in word initial syllable initial, word medial syllable initial, word medial syllable final, word final syllable final positions. The findings were as follows. First, the phonological error patterns of SPD were 1) similar to those of normal children with the same PCC, 2) similar to those of normal children with the lower PCC, or 3) unusual to those of normal children. Second,. korean children showed phonological processes reflecting the korean phonological characteristics: tensification, reduction of the word medial syllable final consonant. This study suggests that both the PCC and error patterns should be considered in assessing phonological abilities of children.

This research with 40 hearing impaired children was performed to find out the characteristics of the phonological processes for each age, hearing loss degree and aided threshold degree through the transcriptions. The phonological processes of hearing impaired children are similar to those of normal children with a peculiar type of patterns in phonological processes. The results show that: (1) Between 5 and 6 year old groups the phonological processes were significantly different in palatal backing, glottal replacement and frication; between 6 and 7 year old groups the phonological processes were significantly different in velar fronting, labialization, alveolization and labial assimilation; between 7 and 8 year old groups the phonological processes, labialization, alveolization and alveolar assimilation, however 8 year old group showed more phonological processes than 7 year old group. (2) Between moderately-severe and severe hearing impaired groups, phonological processes were significantly different in the omissions of postvocalic, nasal and velar, stopping and stop assimilation. The differences of severe and profound groups were not found at all. (3) Aided hearing thresholds did not show any significant difference.

This study aims to compare the differences between 'consonant inventory size' and 'phonological variability' in order to examine the phonological development and characteristics of the late-talkers and typically developing expressive language agematched children and to consider the correlations between them. The study participants included fifteen late-talkers and fifteen typically developing expressive language age-matched children(TED group). The results are as follows. First, as regards consonant inventory size, there was a significant difference between late-talkers and TED group. The late-talkers' consonant inventory size was less than TED group. Second, as regards phonological variability, there was a significant difference between late-talkers and TED group. The late-talkers' phonological variability was higher than TED group. Third, in the case of late-talkers, there was no significant correlation between consonant inventory size and phonological variability; however in the case of TED group, there was a significant negative correlation between consonant inventory size and phonological variability. Therefore, phonological ability should be considered in evaluation and intervention of late-talkers.

In this paper, a standardized phonological rule should be embodied for all people who want to use Hangul beyond nationality. This researcher suggested a phonological process protocol in unicode for the purpose of developing a computer system-based program as one of methods to pronounce Hangul correctly. First of all, to solve a problem of standardizing Hangul pronunciation, it is necessary to develop a phonological process system. In other words, when a mobile phone or a keyboard is used, inputted strings should be changed exactly by an automatic device made according to the phonological rule. For this, a phonological process table is the most important and unicode which digitalizes Hangul is the most effective. Therefore, the purpose of this study is to complete a phonological process table, suggest an algorithm by the table, and develop a computer program pursuing correct Hangul pronunciation. For the methodology of this study, the features of unicode was used to solve a problem of coding each syllable by phonemes after strings were inputted from the phonological process program. This study suggested a protocol that sounds of inputted strings were automatically changed via recombination using a phonological process table. The ultimate purpose of the study was to help pronounce Hangul correctly according to the pronunciation rule.

This study explores the effects of phonological awareness instruction with phonetics on listening comprehension and speaking. For the test of measuring the improvement of listening comprehension, two nationwide listening comprehension tests were used for pre-test and post-test. To find out the improvement of speaking ability, students were required to take the Level-3 NEAT speaking tests. There was a notable correlation between phonological awareness instruction with phonetics and listening ability. Also a significant correlation between phonological awareness instruction with phonetics and speaking ability was found. The group with phonological awareness class with phonetics received higher scores in listening and speaking test than the group without phonological awareness class with phonetics in the post-test. This study implies that phonological awareness class with phonetics is helpful for the improvement of listening and speaking ability. With this research, we can also say that students' communicative competence increased.

Recently, many researchers have been interested in children with phonological disorders. The purpose of this study was to examine those children in comparison with normal children and to find better assessment criteria of the whole-word approach. Three children with phonological disorders and three normal children of 5 to 7 years old participated in the picture description tasks. Results of this study were as follows: there was a significant difference in the whole-word assessment between normal and phonological disorder children. Such criteria as whole-word correctness, whole-word complexity, whole-word intelligibility proved to be good for diagnosing children's phonological disorders. Further studies would be desirable to apply the approach to more children of various age groups.

The purpose of this study was to find an effect of Metaphon Intervention on the improvement of speech intelligibility of preschool children with articulation-phonological disorders. Subjects were 4 preschool children with articulation-phonological disorders. A multiple baseline design across subjects was used to examine the effect of the program. The program consisted of 2 steps. The first step was composed of concept level, sound level, phoneme level, and word level. The second step was on sentence level. Results were as follows: First, metaphon ability of all subjects was improved after the Metaphon Intervention. Second, speech intelligibility of all subjects was improved after Metaphon Intervention. From the results above, Metaphon Intervention can be effective to improve not only phonological awareness and metaphon but also overall speech intelligibility of preschool children with articulation-phonological disorders.
