This study reports syllable position effects on second language (L2) Portuguese speech perception, revealing that L2 segmental learning may be prone to an influence from the suprasegmental level. The results show that first language (L1) Mandarin learners had diminished performance on the discrimination between the target Portuguese liquids (/l/…

Previous studies have yielded contradictory results on the relationship between perception and production in second language (L2) phonological processing. We re-examine the relationship between the two modalities both within and across processing levels, addressing several issues regarding methodology and statistical analyses. We focus on the…

Purpose: This study tested the hypothesis that audiovisual training benefits children more than it does adults and that it improves Japanese-speaking children's English /r/-/l/ perception to a native-like level. Method: Ten sessions of audiovisual English /r/-/l/ identification training were conducted for Japanese-speaking adults and children.…

Over the last two decades, there has been an increasing interest in third language (L3) phonology (Cabrelli Amaro, 2012; Cabrelli Amaro & Wrembel, 2016). However, research so far has been primarily directed at specific stages of learning and has independently explored either production (e.g., Llama, Cardoso, & Collins, 2010; Llama &…

The present dissertation analyzed speech production and perception in early heritage Spanish-English bilingual children. Specifically, I investigated how perception and production of lexical stress develops in bilingual children. Current models of second language (L2) speech perception do not include heritage bilinguals or suprasegmental aspects…

This dissertation research examines the acquisition of second language vowels. For second language learners, learning a new languages' sound inventory, particularly its vowels, presents a challenge perceptually and in terms of production. Incorrectly perceiving and producing sounds in a second language results in a foreign accent in many adult…

To date, a growing number of studies have shown that domain-general auditory processing, which prior work has linked to L1 acquisition, could explain various dimensions of naturalistic L2 speech proficiency. The current study examined the generalizability of this topic to L2 speech learning in classroom settings. The spontaneous speech samples of…

Spanish native speakers are known to pronounce onset /sC/ clusters in English with a prothetic vowel, as in "esport" for sport, due to their native language phonotactic constraints. We assessed whether accurate production of e.g. "spi" instead of "espi" was related to accurate perceptual discrimination of this…

Bilingual speakers must acquire the phonemic inventory of 2 languages and need to recognize spoken words cross-linguistically; a demanding job potentially made even more difficult due to dialectal variation, an intrinsic property of speech. The present work examines how bilinguals perceive second language (L2) accented speech and where…
