Cues to gemination in word-initial position in Maltese

In this study we investigated word-initial geminates in Maltese, focusing on sub-segmental acoustic durations: constriction duration and, where appropriate, VOT; and the duration of adjacent segments: the tonic vowel duration and the duration of the inter-consonantal interval spanning the word boundary. This latter interval, between the consonant in the previous word and the singleton/geminate consonant, is measured so as to capture the presence and duration of a vocalic element, which has been referred to as epenthetic, and reportedly precedes word-initial geminates in the language. Whilst constriction duration plays an important role in distinguishing geminates from singletons (a ratio of 1.7:1), VOT does not. Moreover, although the duration of the following tonic vowel plays no role, the duration of the preceding context – the inter-consonantal interval – is a strong cue to gemination word-initially.peer-reviewe

Not all geminates are created equal : evidence from Maltese glottal consonants

Many languages distinguish short and long consonants or singletons and geminates. At a phonetic level, research has established that duration is the main cue to such distinctions but that other, sometimes language-specific, cues contribute to the distinction as well. Different proposals for representing geminates share one assumption: The difference between a singleton and a geminate is relatively uniform for all consonants in a given language. In this paper, Maltese glottal consonants are shown to challenge this view. In production, secondary cues, such as the amount of voicing during closure and the spectral properties of frication noises, are stronger for glottal consonants than for oral ones, and, in perception, the role of secondary cues and duration also varies across consonants. Contrary to the assumption that gemination is a uniform process in a given language, the results show that the relative role of secondary cues and duration may differ across consonants and that gemination may involve language-specific phonetic knowledge that is specific to each consonant. These results question the idea that lexical access in speech processing can be achieved through features.peer-reviewe

The production and perception of peripheral geminate/singleton coronal stop contrasts in Arabic

Gemination is typologically common word-medially but is rare at the periphery of the word (word-initially and -finally). In line with this observation, prior research on production and perception of gemination has focused primarily on medial gemination. Much less is known about the production and perception of peripheral gemination. This PhD thesis reports on comprehensive articulatory, acoustic and perceptual investigations of geminate-singleton contrasts according to the position of the contrast in the word and in the utterance. The production component of the project investigated the articulatory and acoustic features of medial and peripheral gemination of voiced and voiceless coronal stops in Modern standard Arabic and regional Arabic vernacular dialects, as produced by speakers from two disparate and geographically distant countries, Morocco and Lebanon. The perceptual experiment investigated how standard and dialectal Arabic gemination contrasts in each word position were categorised and discriminated by three groups of non-native listeners, each differing in their native language experience with gemination at different word positions. The first experiment used ultrasound and acoustic recordings to address the extent to which word-initial gemination in Moroccan and Lebanese dialectal Arabic is maintained, as well as the articulatory and acoustic variability of the contrast according to the position of the gemination contrast in the utterance (initial vs. medial) and between the two dialects. The second experiment compared the production of word-medial and -final gemination in Modern Standard Arabic as produced by Moroccan and Lebanese speakers. The aim of the perceptual experiment was to disentangle the contribution of phonological and phonetic effects of the listeners’ native languages on the categorisation and discrimination of non-lexical Moroccan gemination by three groups of non-native listeners varying in their phonological (native Lebanese group and heritage Lebanese group, for whom Moroccan is unintelligible, i.e., non-native language) and phonetic-only (native English group) experience with gemination across the three word positions. The findings in this thesis constitute important contributions about positional and dialectal effects on the production and perception of gemination contrasts, going beyond medial gemination (which was mainly included as control) and illuminating in particular the typologically rare peripheral gemination

The Role of Perception in the Typology of Geminate Consonants: Effects of Manner of Articulation, Segmental Environment, Position, and Stress

The present study seeks to answer the question whether consonant duration is perceived differently across consonants of different manners of articulation and in different contextual environments and whether such differences may be related to the typology of geminates. The results of the crosslinguistic identification experiment suggest higher perceptual acuity in labeling short and long consonants in sonorants than in obstruents. Duration categories were also more consistently and clearly labelled in the intervocalic than in the preconsonantal environment, in the word-initial than in the word-final position, and after stressed vowels than between unstressed vowels. These perceptual asymmetries are in line with some typological tendencies, such as the crosslinguistic preference for intervocalic and post-stress geminates, but contradict other proposed crosslinguistic patterns, such as the preference for obstruent geminates and the abundance of word-final geminates

On the phonetic realization and variation of consonant geminates in Sakha

This study examines the phonetic realization of geminates of different manners of articulation in an underdocumented Turkic language Sakha using production data from a native speaker. Meanwhile, the temporal compensation between geminates and their surrounding vowels is examined by varying the length of the vowels surrounding the target consonants. Results show that in Sakha, geminates differ from their singleton counterparts mainly by showing a longer overall consonant duration. Regardless, gemination is realized differently for consonants with different manners of articulation. Finally, vowel length is an enhancement cue for the realization of geminates

Syllable structure and gemination in Maltese

Little is known on the phonetics and the phonotactic constraints of Maltese. This dissertation sheds light on aspects of syllable structure and geminates in Maltese in order to contribute to understanding how the sound system of the language is structured. The study begins by describing the possible syllable structures in Maltese, carefully defining the onsets, nuclei and codas attested in its syllables. Furthermore, the syllabification processes employed in Maltese are discussed. The dissertation then moves on to its primary focus: geminates in Maltese. In relation to syllable structure, geminates in word-medial position are considered to be ambisyllabic, however, the syllable affiliation of word-initial and word-final geminates is under scrutiny. In addition to word-medial geminates, Maltese also has word-initial and word-final geminates. Previous descriptions of Maltese word-initial geminates (e.g, Azzopardi 1981) have claimed that such geminates are preceded by the epenthetic vowel [ɪ]. Based on a series of production studies, I provide acoustic evidence to examine the articulation of word-initial geminates, and show that this epenthesis occurs almost always when the preceding word ends in a consonant. However, when the preceding word ends in a vowel, there are a number of strategies which speakers employ. Subsequently, in a perception experiment, I show that native speakers of Maltese are insensitive to true word-initial geminates (#ss); results indicate that native speaking Maltese listeners could not discriminate between true word-initial geminates (#ss) and word-initial singletons (#s). However, they were able to discriminate between word-initial geminates that were preceded by the epenthetic vowel (#ɪss) and word-initial singletons (#s). Therefore, I argue that this vowel is part of the phonological representation of word-initial geminates, and I discuss implication of these results for lexical access. In addition, I compare word-initial and word-medial geminates and word-final and word-medial geminates. As expected, the most robust correlate is constriction duration as geminates are always longer than singletons. Other correlates, such as voice onset time, does not serve as a correlate to gemination in Maltese. However, the duration of the vowel before word-medial geminates is shorter than the vowel before word-medial singletons and this can serve as a correlate to gemination in production. Finally, I address the consequences that these results have for phonological representation. Following the current literature on gemination, I propose a moraic representation for geminates in Maltese, regardless of their position in the word

Maltese

This chapter presents an overview of the most prominent contact-induced developments in the history of Maltese, a language which is genetically a variety of Arabic, but which has undergone significant changes, largely as a result of lengthy contact with Sicilian, Italian, and English. We first address the precise affiliation of Maltese and the nature of the historical and ongoing contact situations, before detailing relevant developments in the realms of phonology, inflectional and derivational morphology, syntax and lexicon
