A Phonological Approach to the Contextual Variances of the English Lateral /l/

오관영 21세기영어영문학회 2014 영어영문학21 Vol.27 No.3

The purpose of this study is to explore distributional variants of English /l/s which are differently realized depending on their contexts, to suggest different methods of analysis through feature geometry, and to compare two contrastive analyses of variants in English dialects, GA and RP, which are performed by rule orderings and level approach each differently. Generally, allophony of the English lateral is shown in two types of forms, prevocalic (clear or light)-l and post-vocalic (dark)-l. These are phonetically distinguishable. However, when we look into some examples, there are other cases in which the /l/s become deleted as in talk or syllabic -ls as in bottle. This paper attempted to account for variants of /l/ in phonological approaches. First, this study showed that, in the cases of the dark-l and l-deletion in monosyllabic words, different methods of analysis suggested in feature geometry with phonetic information were clearer and more concise than the approaches based on rule orderings. Second, for the identification of the clear and dark-l, this paper introduced level approaches to account for these variations. As a result, they offer briefer and more convincing explanations to variants in words which were followed by morphological boundaries or were disyllabic than approaches based on rule orderings.

접미사 첨가에 따른 음운현상

오관영 한국현대언어학회 2000 언어연구 Vol.16 No.2

The purpose of this paper is to show the new method to be able to deal with the phenomena by suffix-adding. The model to use in this paper is based on the Harmonic Theory. Because the framework of Harmonic Theory can explain the stress shift and vowel laxing compositively in English word. In the past the stress and vowel laxing in English have been treated in Lexical Theory and Metrical Theory separately. Therefore we can not resolve the matter satisfyingly. But in this paper I will suggest new approache, which depends on a Modified Rhythm Rule and a new foot structure, and so can show the stress shift and laxing to be associated with each other closely.

Prosodic Approaches to Ambisyllabic Consonants in English

오관영 국제언어인문학회 2016 인문언어 Vol.18 No.-

This paper explores the characteristics of ambisyllabicity in order to investigate a motive for it. After reviewing previous explanatory methods, we suggested a new approach based on prosodic structure, and through the new representation, we can account for the sonorant devoicing and the difference of segment duration in gemination by ambisyllabicity. First, we critically reviewed some approaches depending on an ambisyllabic rule and the syllable weight principle, but those analyses did not provide a satisfactory explanation regarding the reason for the intervocalic consonant to be treated as an ambisyllabic consonant. However, when we adopt the moraic structure, we can show ambisyllabicity well in the correlation between syllable weight and stress. As regards flapping and ambisyllabicity, which are regarded as occurring in the same environment, to the contrary, in this paper, we can recognize that the environments of each of ambisyllabicity and flapping are not always the same. Also, with respect to sonorant devoicing, when the intervocalic consonants are treated as ambisyllabic, we can well account for the reason why the sonorant devoicing occurs. Finally, with respect to gemination, although gemination has the same environments as ambisyllabicity, we can demonstrate that, first, gemination phonologically derived across a word boundary results in ambisyllabicity, and second, geminates are not the same in segment duration depending on the ambisyllabic structures. Thus we can say that geminates do not exhibit the same characteristics as ambisyllabicity, and geminates are longer in segment duration than a singleton.

성절자음에 대한 통합적 분석: /l/ 과 /n/ 중심으로

오관영 한국현대언어학회 2019 언어연구 Vol.35 No.1

The purpose of this study is to explore the underlying forms and formation processes of the syllabic consonants of /l/ and /n/, identify issues of previous studies related to them, and then suggest new approaches based on Harmonic theory. For this, first, we considered the conditions and constraints of syllabic consonants. However, some cases were founded which were not consistent with the syllabic conditions or with the restriction of homorganicity between the syllabic liquids and the preceding consonants. As a result, we suggested two kinds of different underlying forms for the syllabic consonants, /Cl/ and /əC/ on the bases of word structures, acoustic analyses, and articulation. Also, comparing three approaches that were based on Generative, Government, and Prosodic explanations, we found limitations on each of them. Thus, through adopting Level-approach within the theory, we can explain concisely both the fluctuation of the syllabic consonants and complex phonological phenomena caused by adding the suffixes –ing and –ily to stems.

A Comparative Study on the Approaches of ŋ-distribution and its Analyses

오관영 국제언어인문학회 2018 인문언어 Vol.20 No.2

The purpose of doing this study is to identify the velar nasal distribution and to explain the phonological phenomena relating to the sequence ng either in words or suffixation from different angles which are based on a harmonic approach. For this, first we consider rule-based analyses such as boundaries (Wolfram and Johnson 1981), a sonority restriction (Roca and Johnson 1999), and lexical levels (Borowsky 1986). However, those showed some limitations of explanation as to the interrelation of g deletion and syllabification closely related to the sequence ng. As an alternative, we examined the constraints-based analyses depending on some constraints such as Max (More-Salient C) >> No Complex Coda >> Max (Less-Salient C) (Lee 1997) or parochial constraint (long([+tense])) and analogical constraint (OO(long, song; ɔ) & OO(long, song; ŋ)), etc. (Green 2001). But those explanations were complicated due to a lack of conciseness as well as either biased towards the deletion of the final consonants or the contexts of vowels occurring before the velar nasal. Therefore, in a harmonic approach, we could explain the issues (g deletion and syllabification of g) relating to the sequence ng more concisely through foot structures in level constructions than through the other analytical methods mentioned.

A Unified Harmonic Approach to Lenitions on Level Structures: Stress Shift and Vowel Shortening

오관영 대한언어학회 2014 언어학 Vol.22 No.3

This study accounts for the correlation between vowel shortening and stress shift triggered by suffixation through foot structures in level-structures. The reason we adopt this approach is that we assume the stress shift and vowel shortening are not separately implemented but they apply simultaneously. Furthermore, this method can give explanations to the phenomena without referring to intermediate derivations and the complexity of rule applications. First, we review a few analytical methods such as phonological rules-based, lexical, CV-level structure, and metrical approaches. Second, due to limitations of these approaches, this study focuses on level-structures to explain the examples discussed in previous studies by suggesting the new devices of a modified Prestress Destressing rule, Minor Weakening and Major Shortening rules, and their conditions for the rule application. Therefore, this study offers more simplified and clearer analytical methods to explain the stress shift and vowel shortening compositely in level-structures than the previous approaches.
