How bilinguals' two languages interact with each other has stimulated considerable research. However, little of this research has focused on objective measures of speech production. This study aims to investigate bilinguals' production of Guoyu and Taiwanese voiceless sibilant fricatives to see how language contact and language dominance influence…

This dissertation examines three processes affecting consonants in child speech: harmony (long-distance assimilation) involving major place features as in "coat" [kouk]; long-distance metathesis as in "cup" [p[wedge]k]; and initial consonant deletion as in "fish" [is]. These processes are unattested in adult phonology, leading to proposals for…

This dissertation investigates the effects of phonological neighborhoods on pronunciation variation in conversational speech. Phonological neighbors are defined as words that are different in one and only one phoneme by addition, deletion and substitution. Phonological neighborhood density refers to the number of neighbors a certain word has. …

The purpose of this study was to identify relationships that exist between reading ability in 3rd grade and phonological awareness in kindergarten. A second purpose was to identify specific prereading skills that best predict later reading success. This study used a quantitative research design to answer the research questions posed. The…

Reading is one of the most critical skills taught in schools (Heller, Fredrick, Tumlin, & Brineman, 2002). Individuals who acquire literacy skills are more likely to experience success in school, and to obtain and maintain employment (Adams, 1990; Light & McNaughton, 2009b; Slavin, Karweit, & Madden, 1989). It is therefore an…

This dissertation is focused on analyzing phonological contact between Slavic and non-Slavic languages in southeastern and northeastern Europe, with the particular goal of describing how the social context of language contact interacts with linguistic factors to shape the outcome of contact-induced change. On the basis of case studies drawn from…

This dissertation measured the acoustic properties of the English fricatives and affricates produced by native and Chinese L2 speakers of English to identify the phonetic basis and sources of a foreign accent and to explore the mechanism involved in L2 speech production and L2 phonological acquisition at the segmental level. Based on a Network…

This thesis investigates the relationship between the phonological distribution of Cw combinations, and the acoustic/perceptual distinctiveness between syllables with plain C onsets and with Cw combination onsets. Distributional asymmetries of Cw combinations discussed in this thesis include the avoidance of Cw combinations in the labial consonant…

This dissertation addresses the extent to which linguistic behavior can be described in terms of the projection of patterns from existing lexical items, through an investigation of Korean reduplication. Korean has a productive pattern of reduplication in which a consonant is inserted in a vowel-initial base, illustrated by forms such as "alok"--"t…

The present study examined the perception of Mandarin disyllabic tones by inexperienced American English speakers. Participants heard two naturally-produced Mandarin disyllables, and indicated if the two were the same or different. A small native Mandarin-speaking control group participated as well. All 21 possible Mandarin contrasts where the…

This study investigated emerging phonemic awareness skills and printed sight word recognition abilities in two-year-old toddlers using plain text and MorphoPhonic Face words on flash cards. MorphoPhonic Face words were used to determine if this learning process is enhanced when words are iconically represented to show the first sound and the…

Recent research has shown that adults can implicitly learn artificial phonotactics constraints from experience producing syllables that contain those constraints, and that this learning is reflected in their speech errors. However, second-order constraints in which the placement of a consonant depends on another characteristic of the syllable…

Purpose: This study was conducted to determine if phonological production proficiency in bilingual Spanish-English preschoolers could be predicted by their language environment, language ability, and phonological production proficiency in their other language. Method: Participants were 199 Latino children and their families. Children ranged in age…

Traditional pronunciation instruction and instruction in second language (L2) phonetics have been shown to improve learners' L2 accent in some, though certainly not all, cases. Learners in intermediate and advanced Spanish FL courses have shown modest improvement in the pronunciation of some L2 phones after receiving such instruction.…

Acoustic and perceptual correlates of emphasis, a secondary articulation in the posterior vocal tract, in Urban Jordanian Arabic were studied. CVC monosyllables and CV.CVC bisyllables with emphatic and plain target consonants in word-initial, word-medial and word-final positions were examined. Spectral measurements on the target vowels at vowel…
