Hierarchy is one of the most important concepts in the scientific study of language. This dissertation aims to understand why we observe hierarchical structures in speech by investigating the cognitive processes from which they emerge. To that end, the dissertation explores how articulatory, rhythmic, and prosodic patterns of speech interact.…

This study investigated suprasegmental variables of syllable stress and intonation contours in contextual speech produced during simultaneous communication (SC) by inexperienced signers. Ten hearing inexperienced sign language users were recorded under SC and speech-alone (SA) conditions speaking a set of sentences containing stressed versus…

Spoken languages are characterized by flexible, multivariate prosodic systems. As a natural language, American Sign Language (ASL), and other sign languages (SLs), are also expected to be characterized in the same way. Artificially created signing systems for classroom use, such as signed English, serve as a contrast to natural sign languages. The…

In many English language classrooms, teaching pronunciation is granted the least attention. When ESL teachers defend the poor pronunciation skills of their students, their arguments could either be described as a cop-out with respect to their inability to teach their students proper pronunciation or they could be regarded as taking a stand against…

My dissertation undertakes a complete study of the stress patterns, syntactic construction, and rhetorical style of hypermetric verse in Germanic alliterative poetry. This project allows me to fill a gap in the study of Germanic meter while simultaneously investigating the connection between metrical and literary scholarship. Hypermetric meter…

The focus of this dissertation is on how language experience shapes perception of a non-native prosodic contrast. In Tokyo Japanese, fundamental frequency (F0) peak and fall are acoustic cues to lexically contrastive pitch patterns, in which a word may be accented on a particular syllable or unaccented (e.g., "tsuru" "a crane", "tsuru" "a vine",…

Over the past few decades, research has demonstrated the important role that prosody (i.e., stress, rhythm, intonation) plays in the intelligibility of speakers of English as a second language (ESL). Yet the impact of this research on teacher cognition--the beliefs and knowledge that teachers possess in relation to their classroom practices--has…

Speech prosody has traditionally been considered solely in terms of its auditory features, yet correlated visual features exist, such as head and eyebrow movements. This study investigated the extent to which visual prosodic features are able to affect the perception of the auditory features. Participants were presented with videos of a speaker…

Recent research has found that sensitivity to linguistic stress is related to phonological awareness and reading development. This study investigated the roles of two types of linguistic stress sensitivity (lexical and metrical stress) in the phonological awareness and reading development of young children. Forty-five kindergarten children were…

The present study explored how average- and high-skilled second-grade readers (as identified by their Woodcock-Johnson III Test of Academic Achievement Broad Reading scores) differed on behavioral measures of reading related to comprehension: eye movements during silent reading and prosody during oral reading. Results from silent reading implicate…

For years, phoneticians have tried to simplify pronunciation for EFL/ESL learners. Some have identified four degrees of primary, secondary, tertiary, and weak stress, and others only three degrees: primary, secondary, and weak. Still others have concentrated on two stress levels: accented versus unaccented, or stressed versus unstressed (Bowen,…

Purpose: In this study, the authors sought to understand acoustic and perceptual cues to contrastive stress in speakers with dysarthria (DYS) and healthy controls (HC). Method: The production experiment examined the ability of 12 DYS (9 male, 3 female; M = 39 years of age) and 12 age- and gender-matched HC (9 male, 3 female; M = 37.5 years of age)…

Learning to read can pose a major challenge to students, and much of this challenge is due to the fact that written language is necessarily impoverished when compared to the rich, continuous speech signal. Prosodic elements of language are scarcely represented in written text, and while oral reading prosody has been addressed in the literature…

This paper evaluates two classes of hypotheses about how people prosodically segment utterances: (1) meaning-based proposals, with a focus on Watson and Gibson's (2004) proposal, according to which speakers tend to produce boundaries before and after long constituents; and (2) balancing proposals, according to which speakers tend to produce…

This thesis has two broad goals. The first is to contribute to the study of Arabic phonology particularly syllable structure and syllabification. This will be achieved through examining phenomena related to syllable structure and syllabic weight such as syllabification, stress assignment, epenthesis, syncope, and sonority in three different…
