  • The Grammar of Coarticulation Edward Flemming Department of Linguistics & Philosophy, MIT
    The Grammar of Coarticulation Edward Flemming Department of Linguistics & Philosophy, MIT 1. Introduction It is well established that coarticulatory patterns are language-specific and therefore must be specified in the grammars of languages (e.g. Beddor, Harnsberger & Lindemann, 2002, Clumeck, 1976, Huffman, 1988, Keating & Cohn, 1988, Magen, 1984, Manuel, 1990, Manuel & Krakow, 1984, Oh, 2002), but there is less consensus on the nature of the grammar of coarticulation. Here we use evidence from the typology of coarticulatory patterns to argue for a model based on weighted constraints. Through two case studies we see that coarticulation shows typological variation that is parallel in many respects to phonological typology: there are common or universal cross-linguistic patterns, such as F0 transitions between adjacent tones, that point to universal constraints, such as physiological limitations on rates of F0 change, but language- specific variation in the details of coarticulation, e.g. variation in the timing of F0 transitions, shows that languages differ in their responses to these constraints. I propose that this is due to interaction between conflicting constraints: constraints on rate of change interact with perceptually motivated constraints requiring the realization of phonetic targets. These constraints can conflict, with conflicts being resolved by constraint prioritization. The relative priority of constraints can differ from language to language resulting in language-specific patterns of coarticulation. This is essentially the same approach to the analysis of typology that has been successful in Optimality Theoretic analyses of phonology (Prince & Smolensky, 2004). This account of coarticulation has implications for analyses that attempt to explain phonological generalizations in terms of phonologization of coarticulation.

  • Is Phonological Consonant Epenthesis Possible? a Series of Artificial Grammar Learning Experiments
    Is Phonological Consonant Epenthesis Possible? A Series of Artificial Grammar Learning Experiments Rebecca L. Morley Abstract Consonant epenthesis is typically assumed to be part of the basic repertoire of phonological gram- mars. This implies that there exists some set of linguistic data that entails epenthesis as the best analy- sis. However, a series of artificial grammar learning experiments found no evidence that learners ever selected an epenthesis analysis. Instead, phonetic and morphological biases were revealed, along with individual variation in how learners generalized and regularized their input. These results, in combi- nation with previous work, suggest that synchronic consonant epenthesis may only emerge very rarely, from a gradual accumulation of changes over time. It is argued that the theoretical status of epenthesis must be reconsidered in light of these results, and that investigation of the sufficient learning conditions, and the diachronic developments necessary to produce those conditions, are of central importance to synchronic theory generally. 1 Introduction Epenthesis is defined as insertion of a segment that has no correspondent in the relevant lexical, or un- derlying, form. There are various types of epenthesis that can be defined in terms of either the insertion environment, the features of the epenthesized segment, or both. The focus of this paper is on consonant epenthesis and, more specifically, default consonant epenthesis that results in markedness reduction (e.g. Prince and Smolensky (1993/2004)). Consonant

    The Scope of Stop Weakening in Argentine Spanish Laura Colantoni and Irina Marinescu University of Toronto 1. Approaches to weakening or lenition Recent experimental studies have documented the weakening of both voiceless (e.g. Lewis, 2000: 2001) and voiced Spanish stops in intervocalic position (e.g. Cole, Hualde & Iskarous, 1999; Ortega- Llebaria, 2004). In addition, synchronic and diachronic studies have repeatedly proposed the existence of a correlation between weakening of voiced and voiceless stops (e.g. Lloyd, 1993). However, very few studies have systematically analyzed both weakening processes in the same variety (Lavoie, 2001), and even fewer have presented experimental evidence demonstrating the existence of such a correlation. In this paper, we analyze the status of both processes in Argentine Spanish in order to motivate hypotheses that would account for diachronic changes in Spanish as well as in other Romance languages. In particular, we evaluate three competing approaches to lenition. The first approach, henceforth Hypothesis A, predicts a positive correlation between an increasing rate of approximantization and deletion of voiced stops and increasing voicing of voiceless stops across places of articulation (e.g. Martinet, 1952; Lloyd, 1993; Wireback, 1997). This approach, which is basically diachronic in nature, sees lenition as a stage towards deletion. The second approach, or the effort-based hypothesis – Hypothesis B -, (Kirchner, 2004; Blevins, 2004) analyzes lenition as effort reduction. As such lenition involves a decrease in the degree of constriction of a given gesture as well as a decrease in duration. Thus, this approach predicts that more effortful gestures should lenite more than less effortful ones, and that the degree of lenition should be affected by the vocalic context.

U.S.A. and Robert Port lndiana University , Bloomington, Indiana 47405, U.S.A. Received 14th May 1985. and in revisedform I Ith January 1986 Some phonologists have claimed that the insertion of a stop between a sonorant and a fricative consonant in syllable-final sonorant­ fricative clusters follows from universal constraints on the human speech perception and produ ction mechanism. Others have claimed that the intrusive stops are products of language or dialect specific phonological rules that are stated in the grammar . In this experiment we examined the produ ction of sonorant - fricative and sonorant-stop­ fricative clusters by two groups of English speakers. One spoke a South African dialect and the other an American mid-western dfalect. The words tested ended in clusters of [n) or [l) plus [s) or [ts) and their voiced counterparts. Spectrographic analysis revealed that the South African speakers maintained a clear contrast between sonorant­ fricative and sonorant-stop-fricative clusters. The American speakers always inserted stops after the sonorant if the fricative was voiceless, but when the fricative was voiced, they more often omitted the stop in underlying clusters containing a stop (/ldz/ or /ndz/) but sometimes inserted a stop in clusters such as /n2/ or /lz/. Measurements of the durations of the vowels, sonorants, stops and the final fricatives were made from the spectrograms . The inserted stop in the American productions was significantly shorter than the underlying one and its presence also affected the duration of the preceding nasal.

For example, Niedzielski (1999) found that the both phonetic and social factors: /u/ in alveolar contexts is apparent regional status of a talker can influence vowel fronter than in bilabial contexts and /u/-fronting is more categorization: participants’ task was to match tokens with advanced in younger speakers. We investigate whether the “Canadian raised” vowels (i.e., [ɑɪ] produced as [ʌɪ]) apparent age of the speaker, via a guise depicting a 21-year- produced by a Detroit speaker to synthetic raised or canonical old woman or a 55-year-old woman, influences whether vowels. Half were told the speaker was from Detroit, while listeners compensate for coarticulation on /u/. Listeners the other half were told speaker was from Canada. Listeners performed a paired discrimination task of /u/ with a raised F2 classified the apparent-Canadian as (accurately) producing (fronted) in an alveolar consonant context (/sut/), compared to non-fronted /u/ in a non-coronal context.

  • Dissertation FINAL
    Gradience and Variability of Intervocalic /s/ Voicing in Highland Ecuadorian Spanish Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Christina Marie García Graduate Program in Spanish and Portuguese The Ohio State University 2015 Dissertation Committee: Dr. Terrell A. Morgan, Advisor Dr. Rebeka Campos-Astorkiza, Advisor Dr. Scott Schwenter Dr. Anna M. Babel Copyright by Christina Marie García 2015 ABSTRACT This dissertation focuses on Highland Ecuadorian Spanish (HES), more specifically in the city of Loja, exploring how linguistic and social factors interact to condition a sound change in progress. While Lojano Spanish has many distinctive features, I examine intervocalic /s/ voicing, that is the variable pronunciation of /s/ as [s] or [z] (for example [losamiɣos] ~ [lozamiɣos] ‘the friends’). This feature has been attested in a few modern dialects of Spanish, most prominently in HES (cf. Robinson 1979) and Catalonian Spanish (McKinnon 2012, Davidson 2014). The present work provides a comprehensive look at this feature in Lojano Spanish by investigating both production and perception. First, I analyze the production of this feature by carrying out a detailed acoustic analysis of 31 recordings with native Lojanos. These recordings were collected during two fieldwork trips spent in Loja in 2010 and 2013. The recordings include both sociolinguistic interviews, as well as a reading task. I measured over 2,969 tokens of /s/ for percent voicing and examined the influence of the following factors: word position, stress, speech rate, preceding/following vowel, and participants’ age and gender. Voicing is analyzed as both a continuous dependent variable (percent voicing) as well as a categorical variable (voicing category).

  • L/ VARIATION in AMERICAN ENGLISH: a CORPUS APPROACH
    Journal of Speech Sciences 1(2): 35-46. 2011 Available at: http://www.journalofspeechsciences.org /l/ VARIATION IN AMERICAN ENGLISH: A CORPUS APPROACH YUAN, Jiahong* LIBERMAN, Mark University of Pennsylvania We investigated the variation of /l/ in a large speech corpus through forced alignment. The results demonstrated that there is a categorical distinction between dark and light /l/ in American English. /l/ in syllable onset is light, and /l/ in syllable coda is dark. Intervocalic /l/ can be either light or dark, depending on the stress of the vowels. There is a correlation between duration (the rime duration and the duration of /l/) and /l/-darkness for dark /l/, but not for light /l/. Intervocalic dark /l/ is less dark than canonical syllable-coda /l/, but it is always dark, even in very short rimes. Intervocalic light /l/ is less light than canonical syllable-onset /l/, but it is always light. We argue that there are two levels of contrast in /l/ variation. The first level is determined by its affiliation to a single position in the syllable structure, and the second level is determined by its phonetic context. Keywords: Corpus Phonetics; Forced Alignment; Syllable; Variation; Liquid *Author for correspondence: [email protected] 36 Yuan J & Liberman N 1 Introduction It has long been observed that the lateral liquid /l/ in English has two main varieties: a light /l/ and a dark /l/. Jones (1966) described the distinction between the two varieties by making a comparison to vowel quality: “An /l/ [light /l/] formed with simultaneous raising of the front of the tongue has a certain degree of acoustic resemblance to /i/, and one [dark /l/] articulated with a depression of the front of the tongue (behind the articulating tip) and raising at the back has an u-like quality or 'u-resonance' as it is often called.” (1) Instrumental investigations of /l/ production in English have revealed two articulatory gestures: raising of the tongue tip and backing of the tongue dorsum.
