Speech shares acoustic features with other sound-based processing, which makes it difficult to distinguish phonological process from acoustic process in speech processing. In this study, we examined the difference between acoustic process and phonological process during repetition tasks. By contrasting various stimuli in different lengths, we localized neural correlates of acoustic process within bilateral superior temporal gyrus, which was consistent with the previous studies. The activated patterns were widely overlapped between words and pseudowords, i.e., contents-free. In contrast, phonological process showed left-lateralized activation in middle temporal gyrus located at anterior temporal areas. It implies that phonological process is contents-specific as shown in our previous study, and at the same time, more language-specific. Thus, we suggest that phonological process is distinguished from acoustic process in that it is always accompanied with the obligatory access to available phonological codes, which can be an entry of the mental lexicon.

With the 130 patients who were diagnosed as functional articulation disorders with no physical problems, a statistical study was performed to investigate their background information and phonological processes of errors. The results are as follows: (1) Males showed higher prevalence than females, and 5-year-old-patients showed the highest in age. (2) Most patients showed errors of 2~5 phonemes (3) The most frequent errors were found in plosives and alveolar sounds, and the most frequent phonological process of errors in the aspects of manner and place of articulation were stop-assimilations and alveolar assimilations, respectively.

The purpose of this study is to examine the lexical representation of phonological variants derived from optional vs. obligatory phonological processes. Given that place assimilation is optionally processed, whereas nasal assimilation is obligatory in Korean, a long-term repetition priming experiment was conducted, using a shadowing task. Korean speakers shadowed words containing either assimilated or unassimilated consonants in three priming conditions and their shadow responses were evaluated. It was shown that in both place and nasal assimilations, shadowing latencies for unassimilated stimuli were longer than those for assimilated stimuli in the mismatched condition. These results suggest that even in the optional assimilation, assimilated variants were processed more easily and faster than the canonical variants. The present results argue against the frequency-based account of multiple lexical representation (Connine, 2004; Connine & Pinnow, 2006; Ranbom & Connine, 2007; $B{\ddot{u}rki$, Ernestus, & Frauenfelder, 2010; $B{\ddot{u}rki$, Alario, & Frauenfelder, 2011).

The present study examined multicultural family children's articulation accuracy and phonological process using Assessment of Phonology and Articulation for Children(APAC), and compared them with normally developing children. The subjects of this study were 24 multicultural family children between ages 3 years, 6 months and 3 years, 11 months. The multicultural family children's articulation accuracy was significantly lower than the normally developing children's. In case of the normally developing children, phonological processes the multicultural family children showed were observed at a younger age and did not appear at the age of the children participating in this study. The Japanese multicultural family children and the non Japanese multicultural family children showed different rate of the changes. This result shows that articulation development in the multicultural family children may be different among them according to the classification and that the children's error patterns are related to their mothers' native language. The results of this study are proposed to be applicable to articulation assessment and treatment.

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.

This study examined how well Korean undergraduate students perceived linked or clear English speech and attempted to find areas of difficulty in their English listening caused by phonological variations. Thirty nine undergraduate students participated in listening sessions. They were divided into high and low groups by their TOEIC listening scores. Samples of linked speech included such phonological processes as linking, palatalization, flapping, and deletion. Results showed that the students had more problem perceiving linked speech than perceiving clear speech. Secondly, both the higher and the lower groups scored low on the linked speech. The lower group had more score difference between linked and clear speech. Thirdly, the students' scores increased from the speech with flapping, through deletion, palatalization, to linking. Finally, there was a strong positive correlation between their TOEIC listening scores and the perception scores. Further studies would be desirable on the level of improvement of TOEIC scores by training the students' listening ability using the linked speech.

This article claims that English liquid consonants are characterized by the presence of complex place nodes, regardless of dialectal varieties. The primary difference between rhotic and laterals can be pursued in a phonological sense. The level of subbranching nodes is in charge of the disparities among two types of liquids: the branching immediately below the Coronal node with laterals, while branching at the secondary sublevel with rhotics. In this context, the processes of rhotic deletion and lateral vocalization can be understood as those motivated to get rid of complex place nodes. That is, those processes take place as part of phonological attrition. Next, the onset/coda asymmetry regarding liquids stems from the dispreference of vocoid at the onset position, which is readily accounted for by the series of constraints on the well-formedness on the onset, namely Harmonic Onset. The rationale of gradualness and harmonic improvement proposed by Harmonic Serialism is useful to separate the attested outputs from unattested ones across the whole gamut of English varieties. All in all, the primary benefits of our analysis can be found in the consistence in the explanation for the operations running through the sounds regarded as belonging to liquid consonants, comprising the whole range of rhotic and lateral consonants.

In this paper, we examine the allophones of an underlying segment /l/ in Korean dialects. In particular, we examine how an underlying /l/ sound surfaces in the Korean dialect spoken at Yonbyon, China. To do so, we employ the following processes: First, we perform the phonetic studies on the allophones of an underlying /l/ in the Yonbyon dialect. Secondly, we compare the phonological environments of the allophones of an underlying /l/ in the Yonbyon dialect with the South Korean dialect. Finally, we discuss the phonological implications of the allophones of the underlying /l/ in terms of Feature Geometry and Syllable Contact Law. Based on the phonetic study, we will argue that the distinctive feature [sonorant] should be placed outside the root node and that the flap, an allophone of an underlying /l/, should be understood as an obstruent, not a sonorant.
