This study examines the effects of task complexity on second language (L2) pronunciation accuracy and global pronunciation measures in pronunciation-unfocused tasks and assesses the relationship between acoustic and listener-based pronunciation measures. Eighty-two Catalan/Spanish learners of English performed simple and complex versions of a…

This study analyses the production of French /y/ and /u/ by 42 native English learners of French (ELoF) at the start and end of a Residence Abroad (RA) in a French-speaking country. As an approximation of both phonological and phonetic development, categorical change is teased apart from gradient change using k-medoid clustering of acoustic data…

This study explored the production of 11 English vowels by Acehnese Indonesian EFL students. Ten undergraduates (five males and five females) from the Pidie District, Aceh, participated, with Acehnese and Bahasa Indonesia as their first languages, and English learned formally at school since the 7th grade. Using PRAAT, recordings of vowel…

This dissertation examines whether EFL and ESL Korean learners of English are able to produce and perceive two English phonological contrasts that depend on vowel duration differences, coda consonant voicing contrasts and the tense-lax distinction in vowels. For production, it examines differences in vowel duration and vowel quality associated…

This study investigates the production of Arabic intervocalic geminate obstruents as produced by American L2 learners of Arabic. The participants of the study were 24 Arabic learners (12 advanced, 12 beginners) at North Georgia University and 12 native speakers of Jordanian Arabic (the control group). An examination of the results reveals that…

Speaker's good pronunciation makes his/her listener comfortable, and confident to participate in the conversation and his/her mispronunciations bring implications to the listener's awareness and involvement with the message spoken. The research was aimed at detecting the mispronunciations produced by 70 nonnative (L2) post-graduate students who…

Because vocabulary knowledge is considered the building block of language learning, any difficulties concerned with vocabulary can harm the overall vocabulary acquisition process. Literature suggests that native Arabic speakers struggle to notice vowels while reading English texts. This can result from the differences between L1 and L2 linguistic…

Although second language (L2) learners often have difficulty with learning the L2 pronunciation, the literature has reported a mix of more successful and less successful learners. Many factors could contribute to individual variation in L2 speech sound learning. This dissertation examines a few factors that are hypothesized to influence L2…

Music plays many important roles in language revitalization, from attracting learners and fostering speech communities to supporting language learning. These effects, however, are largely independent from the skills which linguists bring to language revitalization. This study introduces one concrete way in which applied linguistics can directly…

Lexical tones are widely believed to be a formidable learning challenge for adult speakers of nontonal languages. While difficulties--as well as rapid improvements--are well documented for beginning second language (L2) learners, research with more advanced learners is needed to understand how tone perception difficulties impact word recognition…

The goal of this dissertation is to better understand the targets of vowels in speech production. Three experiments investigate vowel production in non-native speech, probing how new vowel categories, and thus targets, are formed. Three research questions are addressed: (1) Do vowels have articulatory targets (as predicted by Browman &…

Previous research in L2 perception has shown limited and diverge findings for final stop voicing contrasts by learners with different L1 backgrounds in comparison to natives of the target language. This paper aimed to investigate L2 learners' perceptual identification of voicing in English final stops based on the duration of succeeding vowel, and…

Previous studies on second language (L2) phonetic acquisition in early bilingual learners have mainly examined immigrants to the L2 country; however, with recent growing dual-language immersion programs, the immersed bilingual group emerged and required more attention in the research. This study aims to investigate vowel patterns of young…

This study addresses the issue of automatic pronunciation assessment (APA) and its contribution to the teaching of second language (L2) pronunciation. Several attempts have been made at designing such systems, and some have proven operationally successful. However, the automatic assessment of the pronunciation of short words in segmental…

The current study explored individual differences in sensitivity to sub-phonemic variation of acoustic cues in the perception of a native language (L1) category in order to test the hypothesis that second language (L2) learners' different sensitivity to the L2-relevant acoustic dimension in L1 perception could explain individual variability in…
