  • Gemination As Fortition?
    Gemination as fortition? Articulatory data from Hungarian Maida Percival, Tamás Gábor Csapó, Márton Bartók, Andrea Deme, Tekla Etelka Gráczi, Alexandra Markó Introduction: This study uses ultrasound imaging to investigate how tongue position differs across singleton and geminate consonants in Hungarian. In previous research, coronal geminates were found to be produced with greater lingual-palatal contact and a higher and flatter tongue (Kochetov & Kang, 2017; Payne, 2006). In Eastern Oromo, ultrasound imaging found similarly results that the tongue was more advanced in the mouth for coronal geminates, suggesting that it was more fully reaching its targeted place of articulation than singletons (Percival et al., 2019). These findings liken gemination with fortition. We follow up on these studies by examining whether there is evidence of differences in lingual articulation in geminates compared to singletons in Hungarian. As previous studies concentrated on coronal stops, we additionally ask if similar patterns of tongue raising or fronting can be found for geminates at other places of articulation as this could indicate how closely the pattern is tied to gemination in general versus a tongue pull mechanism limited to coronals. Methodology: Five native speakers of Hungarian (3 female, 2 male) were recorded with ultrasound and audio in Articulate Assistant Advanced (AAA). They read six repetitions of a word list containing geminate and singleton voiced and voiceless bilabial stops, alveolar stops, alveolar fricatives, and velar stops in intervocalic (post-tonic) position. Ultrasound frames at the point of maximum constriction were selected, and tongue contours were traced in AAA. The tongue contours were rotated to the speaker’s bite plane and divided into three regions (coronal, velar, and pharyngeal) (c.f.

Muller The Ohio State University Cypriot Greek contrasts singleton and geminate consonants in word-initial position. These segments are of particular interest to phonologists since two divergent representational frameworks, moraic theory (Hayes 1989) and timing-based frameworks, including CV or X-slot theory (Clements and Keyser 1983, Levin 1985), account for the behavior of initial geminates in substantially different ways. The investigation of geminates in Cypriot Greek allows these differences to be explored. As will be demonstrated in a formal analysis of the facts, the patterning of geminates in Cypriot is best accounted for by assuming that the segments are dominated by abstract timing units such as X- or C-slots, rather than by a unit of prosodic weight such as the mora. Keywords: geminates, representation, phonology, Cypriot Greek 1. Introduction Cypriot Greek is of particular interest, not only because it is one of the few varieties of Modern Greek maintaining a consonant length contrast, but more importantly because it exhibits this contrast in word-initial position: péfti ‘Thursday’ vs. ppéfti ‘he falls’.Although word-initial geminates are less common than their word-medial counterparts, they are attested in dozens of the world’s languages in addition to Cypriot Greek.

Ramamoorthy =========================================================== Abstract This paper investigates vowel length in Arabic and how it gets affected by neighboring consonants, in particular when it occurs in geminated or non-geminated phonetic environment in words. The paper examines vowel length before and after geminated and non-geminated consonants. It also focuses on the length of geminated/non-geminated consonants themselves and the proportion between them. The present study also investigates the proportion of vowels to consonants in the words and the proportion of geminated words to their non-geminated counterparts as a whole. Eighteen geminated and non-geminated Arabic words are selected and recorded randomly by the researcher who is a native speaker of Arabic. The data were recorded at the Phonetics Lab of the English and Foreign Languages University in Hyderabad/India. It was concluded that gemination in Arabic affects vowel and consonants as well as total length/ duration of the word as a whole. It is also observed that some vowels/ consonants have greater proportion than their non-geminated counterparts. The whole words were also affected by germination in terms of length and duration.

  • Morphological Sources of Phonological Length
    Morphological Sources of Phonological Length by Anne Pycha B.A. (Brown University) 1993 M.A. (University of California, Berkeley) 2004 A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Linguistics in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Sharon Inkelas (chair) Professor Larry Hyman Professor Keith Johnson Professor Johanna Nichols Spring 2008 Abstract Morphological Sources of Phonological Length by Anne Pycha Doctor of Philosophy in Linguistics University of California, Berkeley Professor Sharon Inkelas, Chair This study presents and defends Resizing Theory, whose claim is that the overall size of a morpheme can serve as a basic unit of analysis for phonological alternations. Morphemes can increase their size by any number of strategies -- epenthesizing new segments, for example, or devoicing an existing segment (and thereby increasing its phonetic duration) -- but it is the fact of an increase, and not the particular strategy used to implement it, which is linguistically significant. Resizing Theory has some overlap with theories of fortition and lenition, but differs in that it uses the independently- verifiable parameter of size in place of an ad-hoc concept of “strength” and thereby encompasses a much greater range of phonological alternations. The theory makes three major predictions, each of which is supported with cross-linguistic evidence. First, seemingly disparate phonological alternations can achieve identical morphological effects, but only if they trigger the same direction of change in a morpheme’s size. Second, morpheme interactions can take complete control over phonological outputs, determining surface outputs when traditional features and segments fail to do so.

  • Introduction to Japanese Computational Linguistics Francis Bond and Timothy Baldwin
    1 Introduction to Japanese Computational Linguistics Francis Bond and Timothy Baldwin The purpose of this chapter is to provide a brief introduction to the Japanese language, and natural language processing (NLP) research on Japanese. For a more complete but accessible description of the Japanese language, we refer the reader to Shibatani (1990), Backhouse (1993), Tsujimura (2006), Yamaguchi (2007), and Iwasaki (2013). 1 A Basic Introduction to the Japanese Language Japanese is the official language of Japan, and belongs to the Japanese language family (Gordon, Jr., 2005).1 The first-language speaker pop- ulation of Japanese is around 120 million, based almost exclusively in Japan. The official version of Japanese, e.g. used in official settings andby the media, is called hyōjuNgo “standard language”, but Japanese also has a large number of distinctive regional dialects. Other than lexical distinctions, common features distinguishing Japanese dialects are case markers, discourse connectives and verb endings (Kokuritsu Kokugo Kenkyujyo, 1989–2006). 1There are a number of other languages in the Japanese language family of Ryukyuan type, spoken in the islands of Okinawa. Other languages native to Japan are Ainu (an isolated language spoken in northern Japan, and now almost extinct: Shibatani (1990)) and Japanese Sign Language.

  • A Study of Korean Phonology and Morphology in a Derivational Approach
    Ecology of PF: A Study of Korean Phonology and Morphology in a Derivational Approach Inkie Chung, Ph.D. University of Connecticut, 2007 This dissertation studies the component of PF, i.e., morphology, phonology and phonetics, in Korean in a consistently derivational approach. Using phonological arguments and an acoustic phonetic study, chapter 2 identifies the surface syllable structure. It also recognizes the two syllable structure constraints: the complex onset constraint and the branching nucleus constraint. Using this syllable structure and these constraints, chapter 3 provides a comprehensive analysis of hiatus in verbal morphology and related issues within Calabrese’s (1995, 2002a) Dynamic Phonology framework. A limited number of actual outcomes for similar hiatus configurations show that the constraint-induced repairs are not finite but limited, and subject to the general principle of economy. It is shown that economy chooses shorter derivations over longer ones, when more than one derivation is possible and yield the same final outcome. It also show's that the hiatus constraint is a non-surface, cyclic constraint, operating once per morphophonological cycle. Furthermore, it argues that certain phonological operations must be described with the traditional rule-like formalism. It is also pointed out that the syllable structure constraints identified in chapter 2 are surface constraints. Chapters 4 and 5 provide a morphological study in Distributed Morphology (Bobaljik 2000, Halle and Marantz 1993, Marantz 2006) With verbal and adjectival roots exhibiting negative and honorific suppletion, these chapters identify the morphological structure of the inflected predicates (and hence phrase structure to a certain extent) in Korean.

  • Contour Tone Distribution in Luganda
    Contour Tone Distribution in Luganda Katharine Dutcher and Mary Paster Pomona College 1. Introduction The traditional model of contour tone distribution (see, e.g., Hyman 2003) uses phonological units to describe which syllable types can bear rising or falling tones (see Zhang 2004 for an overview). A common pattern is one in which contour tones are permitted on long vowels but not on short vowels; this is explained in the traditional model by assuming that the mora is the tone-bearing unit (TBU) and there is a one-tone-per-mora restriction that prohibits contour tones on short vowels. An alternative to the phonological approach is one in which contour tone distribution is phonetically based (see, e.g., Gordon 2001, 2006, Zhang 2001, 2004). In the phonetic model, there is no role for the mora in determining contour tone distribution; instead, it is duration and/or sonority that determine whether a contour can occur on a given syllable. In this paper, we show how Luganda bears on the choice between the two models, favoring the phonological approach over the phonetic one. As we will show, the mora is crucial to explaining contour tone distribution in Luganda, and the duration-based phonetic model makes incorrect predictions for this language. 2. Two competing approaches In the phonetic approach proposed by Zhang (2001), contour tones need a minimum sonorous rime duration (SRD) in order to be realized on a given syllable. SRD is defined as the duration of the syllable nucleus plus any sonorant consonant(s) in the coda, but crucially not including any obstruent coda consonants.

  • Compensatory Lengthening Versus Gemination In
    Compensatory Lengthening versus Gemination in Ancient Greek* Dominique Rodier McGill University o. Introduction Some of the most recent studies in phonology have been concerned with the 'Principles and Parameters' approach to the study of the language faculty, as illustrated in work by Bouchard (1982), Kaye and Lowenstamm (1981, 1982, 1983), Piggott and Singh (1984), etc. Certain phonological processes are found in numerous languages. To describe them simply in terms of language-specific rules would suggest that very important generalizations are being missed. The alternative to describing those processes by means of phonological rules would be to appeal to the principles and parameters of Universal Grammar. As Singh (1980, 1981a,b,c) has argued, some phonological processes can be characterized as repair strategies triggered by well-formedness conditions on syllabic structure. Each of these strategies (e.g. Deletion, Epenthesis, etc.) would be the result of the setting of some parameter, an option that, in principle, is given to every grammar. Each grammar would have to decide which strategy would be used to repair syllables which are not well formed. The choice of a particular parameter may be linked to universal or language-specific constraints on syllable structure. The setting of one parameter may also be prompted by the prior setting of another parameter. Compensatory Lengthening is one of those phonological processes that are found in language after language. In this analysis, I will try to explain this particular process in terms of properties of syllable structure and argue that it can be seen as a repair strategy which is triggered by the need to preserve a certain kind of syllable structure.
