The effects of lexical stress, intonational pitch accent, and speech rate on vowel quality in Catalan and Spanish
… languages tend to display stress-induced vowel quality variation. In some languages the effect is very salient, resulting in a smaller vowel inventory in unstressed syllables and stress-conditioned rule-governed vowel alternations within paradigms (phonological vowel reduction). Other …

High Initial Tones and Plateaux in Spanish and Portuguese Neutral Declaratives: Consequences to the Relevance of F0, Duration and Vowel Quality as Stress Correlates
… seems to be adjusted according to segmental quality and to apply to different dialects over the Brazilian country. This research also shows that the effect of stress in vowel quality is much more consistent in Brazilian Portuguese than in Spanish. Together, these results have implications in …

Sound perception and production in a foreign language
… study addresses the question of how German vowels are perceived and produced by Polish learners of German as a Foreign Language. It comprises three main experiments: a discrimination experiment, a production experiment, and an identification experiment. With the exception of the …

Supralaryngeal Articulator Movements and Laryngeal Control in Mandarin Chinese Tonal Production
… influence of vocal tract configuration on F0 of vowels was noted for all participants. However, not all participants demonstrated the influence of F0 control on vowel quality. Similarly, articulatory compensation was not noted for all participants for tongue height adjustments when the jaw was …

An acoustic phonetic analysis of African American English: A comparative study of two dialects
… (NCS). I analyze these samples to determine if vowel quality and vowel duration are consistently and predictably varied between the two dialects. Labov's Chain Shift Principles are used as the context for the results.</p> <p>In my analysis, I find that both vowel quality and duration are …

Some aspects of English phonology: An optimality theoretic approach
… include three types of phonological phenomena: vowel quality discrepancies, Cluster Simplification, and Voicing Assimilation. This thesis focuses on why these phenomena occur. The goal of this work is to explore the motivating forces of these phenomena and present a principled account of the …

Acoustic Realization and Perception of English Lexical Stress by Mandarin Learners
… intensity, and F2 in stressed and unstressed vowels in noun-verb word pairs contrasting in stress location (e.g. object-object) was conducted. The results indicate that native English speakers use all correlates in nouns but rely mostly on duration in verbs. The learners use these cues more …

A study of vowels /ɛ/ and /ɪ/ in African American English and standard American English
<p>This study examines the vowels /ɪ/ as in tin and /ɛ/ as in ten in African American English (AAE) and Standard American English (SAE) spoken in the Detroit, Michigan area. I first analyzed the acoustic properties of a number of speech samples to determine vowel quality and duration measurements. …

Topics in the stress and syntax of words
… of words in English, arguing that stress and vowel quality in English can be diagnostic of Spell-Out domains within words and that in turn syntactic domains predict the Spell-Out. Chapter 4 is an analysis of Slovenian participial nominalizations. It is first shown that these nominalizations …

The production and perception of Libyan Arabic stress patterns by English speaking learners: A comparison with native speakers
… structural effects (e.g. syllable structure, vowel quality, syllable position or class) have consequences on how the learners perceive and produce stress and on how they use this information in assigning stress. The study found that if the stress patterns match in the L1 and L2, and they …

Perceptual sources for closed-syllable vowel laxing and derived environment effects
… of two challenging phenomena: closed-syllable vowel laxing (CSVL), i.e. the tendency for vowels to be lowered and centralized before word-final and preobstruent consonants, and phonologically-derived environment effects (PDEEs), i.e. patterns where a phonological process is blocked unless …

Phonology-Morphology Interaction in Abha Arabic: Vowel Processes in Stratal Optimality Theory
… The main motivations are providing an account of vowel processes in Abha Arabic and testing Stratal OT’s ability to account for vowel epenthesis, vowel lengthening, and vowel shortening. The Stratal OT framework is put to the test to see if it can account for opacity, which proved to be …

Stress and Syncope in Tobruq Arabic an Eastern Libyan Dialect: A Stratal OT Account
… stress patterns and their assignment, as well as vowel syncope and the contrasting behaviour of epenthetic vowel insertion. The former processes are shown to be affected by two morphological factors: the type of word class, and the type of morphological ending that attaches to a monomorphemic …

Sociophonetics and class differentiation: A study of working- and middle- class English in Cape Town's coloured community

The phonetic correlates of pharyngealization and pharyngealization spread patterns in Cairene Arabic an acoustic and real-time magnetic resonance imaging study
… of the second formant frequency in surrounding vowels. The extent of the modification in the formant frequency is determined by the length and quality of the vowel. This study uses real-time magnetic resonance imaging (rtMRI) to investigate the acoustic and articulatory correlates of …
