Current L2 utterance fluency literature tends to operationalize disfluency as isolated, individual features. However, disfluency features often co-occur at one location or across multiple locations in one utterance. This study explores the co-occurrence of L2 disfluency features in a speech corpus from 71 L1 and L2 speakers of English across…

In an exploration of the effects of task-repetition practice on fluency development, English-as-a-foreign language learners performed three oral narrative tasks involving six-frame cartoons for 3 consecutive days. They engaged in task-repetition practice under either a blocked (Day 1: A-A-A; Day 2: B-B-B; Day 3: C-C-C) or an interleaved (Day 1:…

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…

This study examined the relationship between oral fluency and use of multiword sequences (MWSs) across four proficiency levels (Low B1 to C1 of the Common European Framework of Reference). Data came from 56 learners taking the speaking test of the Test of English for Educational Purposes, and our analysis obtained different measures of fluency…

This study examines the relationship between different types of language learning aptitude (measured via the LLAMA test) and adult second language (L2) learners' attainment in speech production in English-as-a-foreign-language (EFL) classrooms. Picture descriptions elicited from 50 Japanese EFL learners from varied proficiency levels were analyzed…

This study examined the impact of video-based conversational interaction on the longitudinal development (one academic semester) of second language production by college-level Japanese English-as-a-foreign-language learners. Students in the experimental group engaged in weekly dyadic conversation exchanges with native speakers in the United States…

The aim of this study was to evaluate the effects of second language (L2) experience--operationalized as length of residence (LOR) in Canada--on late Japanese learners of English. Data collected from 65 participants consisted of three groups of learners (short-, mid-, and long-LOR groups) and two baseline groups of native Japanese and native…

Although fluency constitutes an essential component of second language (L2) proficiency, there are mixed results and gaps in the literature on how L2 speakers' fluency differs from fluent speech production in a first language (L1). The research reported in this article investigated utterance fluency and cognitive fluency of L1 English…

The present study investigates the role of speech repetition in oral fluency development. Twenty-four students enrolled in English-as-a-second-language classes performed three training sessions in which they recorded three speeches, of 4, 3, and 2 min, respectively. Some students spoke about the same topic three times, whereas others spoke about…

Researching the longitudinal development of second language (L2) learners is essential to understanding influences on their success. This 7-year study of oral skills in adult immigrant learners of English as a second language evaluated comprehensibility, fluency, and accentedness in first-language (L1) Mandarin and Slavic language speakers. The…

This nonexperimental study explored the predictive strength of English proficiency levels on academic achievement of middle school students in a sample of 17,470 native English-speaking (NES) students, 558 English language learners (current ELLs), and 500 redesignated fluent English proficient students (former ELLs). Results of multilevel analyses…

Drawing on current theories in personality, second-language (L2) oral ability, and psychometrics, this study investigates the extent to which self-consciousness and assertiveness are explanatory variables of L2 oral ability. Three hundred sixty first-year Japanese university students who were studying English as a foreign language participated in…

This longitudinal study investigates the development of writing proficiency in English as a foreign language (EFL), in contrast to the development of first language (L1) writing proficiency in Dutch L1, in a sample of almost 400 secondary school students in the Netherlands. Students performed several writing tasks in both languages in three…

We report a classroom experiment directed at increasing lexical fluency in writing. Participants were 107 Dutch students in bilingual (EFL) education (Grades 10 and 11). According to current theories of writing such fluency allows writers to devote more attention to higher order aspects of text production, such as idea generation, selection and…

This study examines the effects of learning context and age on second language development by comparing the language gains, measured in terms of oral and written fluency, lexical and syntactic complexity, and accuracy, experienced by four groups of learners of English: children in a study abroad setting, children in their at-home school, adults in…
