While language dominance has been crucial in the study of bilingualism, recent research has called for more detailed measures to systematically account for the observation that bilinguals use different languages in different domains, a phenomenon formalized in the Complementary Principle. Few studies have systematically measured these…

Persuasiveness in oral communication in English can be expressed with various vocal phonetic cues that may not be readily accessible to English second language (L2) learners whose native language may employ a different set of cues. With a goal to increase L2 learners' perceived spoken confidence and persuasiveness, and obtain empirical evidence…

Adult learners acquire second language (L2) allophones with experience. We examine two mechanisms which may support the acquisition of allophonic variants in second language acquisition. One of the mechanisms is based on the distribution of phones with respect to their phonological context (i.e. phonological distribution). The other is based on…

This article examines the use of prompt-based lexical collocations in opinion essays by Vietnamese English as a foreign language (EFL) students. Fifty second-year English majors at a Vietnamese university wrote 100 opinion essays on two topics as progress tests. The AntConc programme (Anthony, 2020) was employed to identify the frequencies of use…

The emergence of AI writing assistants has raised concerns about their potential impact on language diversity, preservation, and education. This paper examines the capabilities and limitations of AI writing assistants in generating dialectic text in response to academic and professional writing prompts. The study uses a concordance tool to conduct…

Developing sociolinguistic competence in Arabic can be a complex process given how Modern Standard Arabic (MSA) and Colloquial Arabic (CA) are used within a changing sociolinguistic environment in Arabic-speaking communities. Findings from empirical research suggest that second language (L2) Arabic learners who receive multidialectal training in…

Spoken word recognition depends on variations in fine-grained phonetics as listeners decode speech. However, many models of second language (L2) speech perception focus on units such as isolated syllables, and not on words. In two eye-tracking experiments, we investigated how fine-grained phonetic details (i.e. duration of nasalization on…

In this work, based on an oral corpus of semi-directed interviews conducted in French with 40 L1 Chinese speakers learning French in France and in English with 29 L1 Chinese speakers learning English in the United States, I investigated the quotative system in non-native speech of English and French as it is used in the Chinese diaspora in Paris…

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…

English became one of the common modes to get back to the audience and common mass. Media jargons and registers are not very easy to handle and vocabulary is a key issue in media studies. This research solely emphasizes on the importance of professional English vocabulary. It also focuses on professional vocabulary of Electronic and Print Media in…

Linguistic ideologies are informed by social stereotyping to maintain the "standard" variety which is often interpreted as morally superior to "nonstandard" varieties. Consequently, these ideologies racialize "nonstandard" varieties, leading to even more negative stereotypes. One outlet of such stereotypes can be…

This study aimed to advance research on first and second language future-time expression in Spanish and to demonstrate the strengths of combining functionalist, concept-oriented approaches (e.g., Andersen, 1984; Bardovi-Harlig, 2000; Shirai, 1995; von Stutterheim & Klein, 1987) with variationist approaches. The study targeted 140 participants…

This book is relevant for language testers, listening researchers, and oral proficiency teachers, in that it explores four broad themes related to the assessment of L2 listening ability: the use of authentic, real-world spoken texts; the effects of different speech varieties of listening inputs; the use of audio-visual texts; and assessing…

The current study examined the extent to which native speakers of North American and Singapore English differentially perceive the comprehensibility (ease of understanding) of second language (L2) speech. Spontaneous speech samples elicited from 50 Japanese learners of English with various proficiency levels were first rated by 10 Canadian and 10…

Over the past few decades, there has been considerable effort to find the mechanisms through which adult listeners can accommodate the rampant phonetic variation in natural speech. My dissertation concerns one source of variability: phonetic variation in speech produced by individuals with foreign accents. Mounting evidence shows that listeners…
