Interaction, corrective feedback, and the development of lexical stress
… the effects of recasts on the development of lexical stress in L2 English. Following a pretest-posttest design, 68 L1 Arabic speakers were randomly assigned to intervention and control groups. The pre- and posttests comprised sentence-reading and decision-making tasks that contained …

Acoustic Realization and Perception of English Lexical Stress by Mandarin Learners
The acquisition of English lexical stress by Mandarin L2 learners was examined. An acoustic study focusing on the implementation of mean F0, max F0, duration, intensity, and F2 in stressed and unstressed vowels in noun-verb word pairs contrasting in stress location (e.g. object-object) was …

Converging evidence on the autonomy and abstractness of the representation of lexical stress
… in the thesis investigate the nature of word stress and its lexical representation. Focusing on Italian, I considered two research questions: How is lexical stress represented? How does this representation intervene in perceiving or producing a word? Italian is a polysyllabic language with …

The effects of lexical stress, intonational pitch accent, and speech rate on vowel quality in Catalan and Spanish
Lexical-stress 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). …

ESL speakers' production of English lexical stress: The effect of variation in acoustic correlates on perceived intelligibility and nativeness
… their production of three acoustic correlates of lexical stress in English, namely the relative durations of stressed and unstressed vowels and their relative intensities and fundamental frequency (F0) values. A set of three-syllable words, including cognates and non-cognates, was analyzed. The …

The perception and production of prominence in Spanish by heritage speakers and L2 learners
… in Spanish: word-level prominence (i.e., lexical stress), marking paradigmatic contrast (e.g., Canto. 'I sing.' vs. Cantó. 'He/She/You (formal) sang.'), and sentence-level prominence (i.e., nuclear stress), marking information status and focus (e.g., ¿Qué hizo Mariana? - Mariana cantó. …

A Phonetic Examination of C -to -V Place Assimilation
The examination of lexical stress effects on C-to-V coarticulation indicates that the degree of coarticulation is not significantly different in stressed and unstressed syllables. This provides a theoretical implication that lexical stress will not be a conditioning factor for C-to-V place …

Speech Rhythm in American English: A Corpus Study
… types of prosodic domains, the ISI (inter-stress interval) and the IAI (inter-accent interval). The main finding is evidence for rhythmic shortening in the domain defined in terms of lexical stress: the duration of vowels (especially stressed vowels) decreases as the size of the ISI …

Multisyllabic Word Reading in Grades 4 and 5: Accuracy, Errors, and Associated Child-Level Skills
… coding scheme developed to assess decoding and lexical stress errors; good readers made proportionally fewer errors, but were more likely to make errors involving shifts in lexical stress. Error productions were also described in terms of lexicalization (reading the item as a real but erroneous …

Phonological Awareness of Stress and Syllable
… and four-syllable pseudo-word forms with varying stress patterns. The present study examined the participants' ability to identify targeted syllables and targeted stressed elements. That is, in one group (syllable group), participants were required to identify the location of a target syllable …

Children's Sensitivity to Pitch Variation in Language
… children must disregard pitch at the lexical level—since English is not a tone language—while still attending to pitch for its other functions. Chapters 1 and 5 outline the learning problem and suggest ways children might solve it. Chapter 2 demonstrates that 2.5-year-olds know pitch …

High Initial Tones and Plateaux in Spanish and Portuguese Neutral Declaratives: Consequences to the Relevance of F0, Duration and Vowel Quality as Stress Correlates
… sentence initial position not only express lexical stress, but phrasal tones as well. According to these results the phrasal tones in Brazilian Portuguese can be presented in the intonational contour as either peaks or plateaux. Results also suggest that duration in Spanish does not play a …

Design of tool for analysis of speech development disorders using landmarks and other acoustic cues
… the syllable, word length measured in syllables, lexical stress, and manner type. Results suggest specific patterns of modification in specific contexts for specific clinical populations. These findings set the foundation for understanding how phonetic variation in speech arises in both typical …

Stress and Epenthesis in Alatawalah Arabic: Classical versus Stratal OT

Rhythmic Sensitivity and Developmental Language Disorder in Children

Raters' different judgments of intelligibility in the English placement test at University of Illinois at Urbana-Champaign
… most raters responded that segmental factors and lexical stress were important factors for their judgment. This might be because English Placement Test is a tool for assessing the ‘word level’ intelligibility. Phase I of the English Placement Test uses a one-on-one interview format or a …

Focal prominence in tone languages: A case study of three Chinese languages
… languages. Drawing from an extensive review of lexical prosody in Chinese, this thesis discerns a pattern of co-occurrence (or absence) of tonal reduction at both lexical and sentential levels. Integrating insights from languages with lexical stress, it is suggested that such correlations are …

Social Functioning Characteristics of a Young Adult with a History of Childhood Apraxia of Speech

Neutral Tone in Mandarin: Representation and Interaction with Utterance-level Prosody
