This study explores whether Koreans exploit their native coda-neutralization process when recognizing words in Korean continuous speech. According to the phonological rules in Korean, coda-neutralization process must come before the liaison process, as long as the latter(i.e. liaison process) occurs between 'words', which results in liaison-consonants being coda-neutralized ones such as /b/, /d/, or /g/, rather than non-neutralized ones like /p/, /t/, /k/, /ʧ/, /ʤ/, or /s/. Consequently, if Korean listeners use their native coda-neutralization rules when processing speech input, word recognition will be hampered when non-neutralized consonants precede vowel-initial targets. Word-spotting and word-monitoring tasks were conducted in Experiment 1 and 2, respectively. In both experiments, listeners recognized words faster and more accurately when vowel-initial target words were preceded by coda-neutralized consonants than when preceded by coda non-neutralized ones. The results show that Korean listeners exploit the coda-neutralization process when processing their native spoken language.

Nominal compounds of 'N1 + N2'in Korean can be classified into the following three major categories: co-compound, sub-compound, and fusion. Among these three major categories, insertion of /t/ in the compounding process and subsequent tensification are found only in sub-compounds. This peculiar phenomenon of /t/-insertion which causes, in turn, tensification in sub-compounds has been long controversial because linguists have not been able to expect in which phonological environment of sub-compounding insertion of /t/ takes place. In this paper, I explore a phonological rule which makes it possible to expect the phonological environments of sub-compounding that allow insertion of /t/ and automatic tensification of the subsequent consonant in the onset of N2. In this process, I show that semantic feature(s) between two combined roots should be considered as one of the important structural descriptions in phonology.

Korean phonology has not recognised metrical foot as a phonological unit to account for certain phonological processes. This paper, however, suggests that an optional h-deletion process in Korean should require the notion of metrical foot as an independent phonological domain. The previous analyses rely on the notion of speech speed to explain optional h-deletion : i. e. an intervocalic h is deleted in fast speech, but in slow speech it remains. This paper claims that the notion of speech speed should be reinterpreted in terms of metrical foot : i.e. foot-internal t is deleted, but foot-initial h remains. Such analysis provides evidence that metrical foot constitutes a phonological unit in Korean phonology. With the notion of metrical foot, it enables us to achieve more detailed and accurate analysis of the optional h-deletion process in Korean.

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.

The purpose of this study is to investigate two phonological error patterns on coronal feature of children with functional articulation disorders and to compare them with those of general children. We tested 120 children with functional articulation disorders and 100 general children from 2~4 years of age with 'Assessment of Phonology & Articulation for Chidren(APAC)'. The results were as follows: (1) 37 disordered children substituted [+coronal] consonants for [-coronal] consonants (fronting of velars) and 9 disordered children substituted [-coronal] consonants for [+coronal] consonants (backing to velars). (2) Theses two phonological patterns were affected by the articulatory place of following phoneme. (3) The fronting pattern of children with articulation disorders was similar with that of general children, but their backing pattern was different with that of general children. These results show the clinical usefulness of coronal feature in phonological pattern analysis, the need of articulatory assessment with various phonetic context, and the importance of error contexts in clinical judgment.

This study addresses the issue of whether Korean(L1)-English(L2) non-proficient bilinguals are affected by the native coda-neutralization process when recognizing words in English continuous speech. Korean phonological rules require that if liaison occurs between 'words', then coda-neutralization process must come before the liaison process, which results in liaison-consonants being coda-neutralized ones such as /b/, /d/, or /g/, rather than non-neutralized ones like /p/, /t/, /k/, /$t{\int}$/, /$d_{\Im}$/, or /s/. Consequently, if Korean listeners apply their native coda-neutralization rules to English speech input, word detection will be easier when coda-neutralized consonants precede target words than when non-neutralized ones do. Word-spotting and word-monitoring tasks were used in Experiment 1 and 2, respectively. In both experiments, listeners detected words faster and more accurately when vowel-initial target words were preceded by coda-neutralized consonants than when preceded by coda non-neutralized ones. The results show that Korean listeners exploit their native phonological process when processing English, irrespective of whether the native process is appropriate or not.

본 논문은 인간의 언어정보처리 과정 중 시각단어재인(visual word recognition) 과정에서 음운정보(phonological information)와 철자정보(orthography information)의 역할 및 심성어휘집의 표상(representation) 형태를 알아보기 위해 신경망(neural network)을 이용한 계산주의적 모델(computational model)을 제안한다. 제안하는 모델은 한국어 2음절을 입력 값으로 사용하는 입력층(input layer), 은닉층(hidden layer) 그리고 의미를 표현하는 출력층(output layer)으로 구성된 전방향 신경회로망(feed forward network) 구조로 설계하였다. 실험결과 계산주의적 모델은 한국어에 대한 시각 단어재인 시 보이는 언어현상 중 음운, 철자 이웃 크기효과(phonological and orthographic neighborhood effect)를 나타냈으며, 이를 통해 한국어 시각단어재인 과정에서 심성어휘집이 음운정보로 표상되어 있음을 시사하는 증거를 보였다.

This study was designed to investigate the changes of phonological processes in normal Korean children aged from 2- to 6-years. Forty eight children who lived in Seoul or Kyung-Ki do were tested with a picture articulation test and their articulation errors including omissions, additions and substitutions were coded into phonological processes. Those phonological processes were discussed in several ways: syllable structure, place, manner, assimilation, tenseness, and aspiration of sounds. Data were analyzed by two ways: (1) number of subjects who showed each process and (2) percentage of occurrence of each process. Analyses in omission-addition processes demonstrated that postvocalic omission occurred most frequently, followed by velar-, alveolar-, and glottal omission. Analyses in substitution processes showed that fronting (palatal and velar), backing (alveolar), and alveolization occurred most frequently in terms of the place of sounds. In terms of assimilation, alveolar-, stopping, and aspiration assimilation occurred frequently. Analyses by the tenseness and aspiration showed similar occurrences among the 4 processes, with slightly higher occurrences in tensing and aspiration than lanxing and deaspiration. All of the processes decreased by age. The numbers of the processes showed by more than half of the children or exceeded 10％ of occurrence were 20 in 2-years of age, 10 in 3-years of age, 1 in 4-years of age, and none in ages of 5 and 6.
