Rhythm metrics can detect second language development of target-like speech rhythm but interpretation of the results from metrics in learners' speech is problematic because the mapping of metrics to underpinning phonological features is indirect. We investigate speech rhythm in first language (L1) Arabic / second language (L2) English, which…

The research explores forms and function of variant tag questions (VTQs) in the native and non-native Englishes. For the said purpose, patterns of VTQs in Pakistani English are compared with two native (British and New Zealand) and two non-native (Indian and Singaporean) varieties. The components of the "International Corpus of English,"…

Input variability is key in many aspects of linguistic learning, yet variability increases input complexity, which may cause difficulty in some learning contexts. The current work investigates this trade-off by comparing speaker variability effects on L2 vocabulary learning in different age groups. Existing literature suggests that speaker…

This study investigates how second language (L2) listeners' perception is affected by two factors: the listeners' experience with the target dialect -- North American English (NAE) vs. Standard Southern British English (SSBE) -- and talkers' language background: native vs. non-native talkers; i.e. interlanguage speech intelligibility benefit…

This dissertation explores subject pronoun expression (SPE) in Palenquero Spanish (PL Spanish) and Palenquero Creole (PL Creole), two languages that have coexisted for centuries in San Basilio de Palenque (Colombia), share most of their lexicon, but differ in their grammar. Crucially, this study investigates how the contact between them and the…

The phenomenon of regularization -- learners imposing systematicity on inconsistent variation in language input -- is complex. Studies show that children are more likely to regularize than adults, but adults will also regularize under certain circumstances. Exactly why we see the pattern of behaviour that we do is not well understood, however.…

A well-known challenge for language learners is that the input is typically produced by a variety of speakers, each with distinct vocal characteristics (Liberman, Harris, Hoffman, & Griffith, 1957). Accordingly, many studies have indicated that talker variability leads to processing costs for learners across the lifespan (Jusczyk & Pisoni,…

It is generally accepted that second language (L2) acquisition becomes more difficult as one grows older and that success in adult L2 acquisition is highly variable. Nevertheless, humans in language contact situations have to cope with intergroup communication. This article examines the ways society has responded to this challenge. It describes…

Studies have examined various factors that affect pronunciation including phonetic context, style variation, first language transfer, and experience abroad. A plethora of research has also linked motivation to higher levels of proficiency in the second language. The present study uses native speaker ratings and multiple regression analysis to…

In this paper, I investigate the phenomenon of morphological variability in the production of Italian determiners, descriptive adjectives, and direct object pronouns by adult English learners of Italian to determine whether morphological errors are the result of computational or representational difficulties. Second language acquisitionists do…

The present article provides an exploration of ultimate attainment in second language (L2) and its limitations. It is argued that the question of maturational constraints can best be investigated when the reference population is bilingual and exposed on a regular basis to varieties of their first language (L1) that show cross-linguistic influence.…

Drawing on reflections of a teacher-researcher in a community-based adult ESL classroom in Toronto, Canada, explores the relationship between identity and intonation. Presents an account of teaching intonation to a group of predominantly Chinese immigrant women, and discusses an activity that develops awareness of sentence-level intonation as a…
