Throughout the 20th Century, linguists have always been looking for the best way to properly describe and explain interfaces among branches of linguistics. This has been inevitable partially due to the double- (or n-tuple-) faced nature of linguistics. Among various trials and errors, the paths drawn by generative linguistics are worth special attention. Its "modular" view of language has made possible a tremendous amount of new findings which were not possible before. However, this "modularity" issue must now come under scrutiny, especially within the components of grammar.

This paper examines the relationship between phonology and phonetics. After reviewing a version of Lexical Phonology and Ladefoged's phonetic view of phonology, I argue that phonology and phonetics are in a derivational relationship and propose a generative phonetic model which is intended to integrate the idea of Lexical Phonology and Ladefoged's view. In the model proposed here, the phonology-phonetics interface is located at the level of allophonic transcription, which is referred to as systematic phonetic transcription (Ladefoged 1993) or categorical phonetic representation (Keating 1990). It is also argued that the psychological reality of this categorical level is supported by a listener's categorical perception.

This article gives an insight into the interface between diachronic grammar and phonology, focusing on the sC clusters in syllable coda position. They may be uniformly assumed to consist of a complex segment, but the historical study of LME and ModE here shows that they behave differently with respect to phonological processes, depending on the place of articulation of the stop consonants. Based on observations of the clusters' relation to MEOSL and GVS, I thus claim that OT gives a principled account for their asymmetry and captures the predictability of diachronic change in a more explicit and natural way than earlier models.

This paper gives a brief introduction to the dynamical systems theory applied to the rhythmic aspects of human behavior, which provides a good example of interface between cognitive science and phonetic studies. Examples of rhythmic behavior range over various phenomena, such as finger wagging, syllable-timed vs. stress-timed languages, and dynamic attending to complex rhythm.

The purpose of this paper is to propose braille symbols for the International Phonetic Alphabet (=IPA) for linguistic researchers like myself who have visual handicaps. To the best of my knowledge, not all symbols of the IPA have been translated into braille, even in America. For example, the reversed symbols and small capitals have not been put into braille. I propose new braille symbols for them and attempt to translate the consonants and vowels of IPA into braille completely.

The distribution of the patterns of nasal-consonant clusters in Catalan has been attributed in the literature to the application of Nasal Assimilation, which correlates with Cluster Simplification. However, the absense of several clusters in this language cannot be accounted for with this kind of analysis. In this paper, I propose that these clusters are absent not only in the output but in the input as well due to several constraints which apply to underlying forms. Furthermore, I will discuss whether the conclusion drawn here poses a problem for Optimality Theory, where it is assumed that inputs are not restricted in any way.

The purpose of this study is to elucidate the nature of disfluencies produced by stutterers and normal speakers of Japanese. The first part of the paper reports the result of a detailed analysis of over 2000 stuttering samples (repetition) produced by 36 stutterers and 286 normal speakers. The analysis has revealed that most of the segmentation patterns in the samples are mora-based segmentations. The second part is to seek the difference between stutterers' and normal speakers' repetitions. The statistic analysis from the viewpoint of a phonetic transition defect has revealed that the trigger of nonstutterers' disfluency is not so relevant to the phonetic transition as that of stutterers'. This implies that the two kinds of disfluencies have different backgrounds. On the other hand, the triggers of stuttering, which are stops, can be interpreted as stutterers' flaws in their phonetic plans. This finding makes up for a weak point of The Covert Repair Hypothesis.
