The extent of quantitative and qualitative differences in phonological development between bilingual children and their monolingual counterparts remains unresolved, especially with regard to typologically-related languages. The current study used a comparative research design to examine the phonological skills of preschool children speaking Polish…

In dialogue, speakers tend to adapt their speech to the speech of their interlocutor. Adapting speech production to preceding speech input may be particularly relevant for second language (L2) speakers interacting with native (L1) speakers, as adaptation may facilitate L2 learning. Here we asked whether Dutch-English bilinguals adapt pronunciation…

This dissertation investigates language-specific acoustic and aerodynamic phenomena in language contact situations. Whereas most work on second language and bilingual phonology has focused on individual consonants and vowels, this project examines patterns of coarticulation in the two languages of Spanish-English and French-English bilingual…

Without data on speech accuracy of Vietnamese-English speakers, speech-language pathologists (SLPs) are unable to assess accurately this population for speech sound disorders. This study explored the heretofore uninvestigated speech accuracy and use of Vietnamese-English bilingual individuals residing in the USA. Participants included six…

This study addressed two areas of inquiry: 1) the influence of enlisting three underlying cognitive learning processes (CLPs) in alphabet learning, and 2) order effects for letter name and letter sound instruction. Alphabet instruction was designed to enlist Paired Associate Learning (PAL) only, PAL plus Orthographic Learning (OL), or PAL plus…

Purpose: To examine how age of immersion and proficiency in a 2nd language influence speech movement variability and speaking rate in both a 1st language and a 2nd language. Method: A group of 21 Bengali-English bilingual speakers participated. Lip and jaw movements were recorded. For all 21 speakers, lip movement variability was assessed based on…

This study is a detailed analysis of the phonological development of Sylvia, a bilingual child, in her acquisition of American English and Brazilian Portuguese from the age of 1 year, 7 months to 3 years, 8 months. The study is divided into four stages: ages 1.7 - 1.9; 1.9 - 2.1; 2.1 - 2.3; and 2.3 - 2.8. Up to the age of 1.9, the same…
