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…

Over the past few decades perspectives on second language (L2) pronunciation have evolved from pessimistic appraisals of the capabilities of L2 learners and doubts about the value of instruction to a view of pronunciation teaching as an effective and important part of language pedagogy. Earlier research on the teaching of pronunciation dwelt…

Research on second language (L2) phonetic learning indicates that, even in adults, segmental acquisition remains possible through L2 experience. However, the findings of previous cross-sectional studies of vowel and consonant learning have proved difficult to interpret. In this longitudinal investigation of 44 recent arrivals in Canada,…

This longitudinal mixed-methods study compared the oral fluency of well-educated adult immigrants from Mandarin and Slavic language backgrounds (16 per group) enrolled in introductory English as a second language (ESL) classes. Speech samples were collected over a 2-year period, together with estimates of weekly English use. We also conducted…

Untrained native English listeners assigned foreign accent scores to sentence and narrative utterances produced by native English speakers and Mandarin-speaking learners of English, rendered unintelligible through low-pass filtering. Because the filtered speech stimuli contained little of what could be considered segmental information, results…

Tested the hypothesis that accented speech heard at a reduced rate would sound less accented and more comprehensible than speech produced at a normal rate. In two experiments, English native-speaker listeners rated a passage read by 10 high-proficiency Mandarin learners of English. Findings suggest that a general speaking strategy of slowing down…

Native English-speaking (NS) listeners evaluated effects of three types of instruction (segmental accuracy; general speaking habits and prosodic factors; and no specific pronunciation instruction) on speech of three groups of English-as-a-Second-Language (ESL) learners. Sentences were recorded and extemporaneously produced narratives at beginning…

Adult English-as-a-Second-Language students enrolled in a speaking improvement course (which emphasized general speaking habits) read aloud lists of true and false sentences at the beginning and end of the course. Native speakers judged their intelligibility, comprehensibility, and accent. Most participants showed significant improvement in at…

Examines the English vowel productions of native speakers of Italian who immigrated to Canada between 2 and 23 years of age and of native English speakers from the same community. Findings reveal an increase in perceived accentedness on every vowel as a function of increasing age of arrival as well as high intelligibility scores for English vowels…

Examines the interrelationships among accentedness, perceived comprehensibility, and intelligibility in the speech of second-language (L2) learners. The findings suggest that although strength of foreign accent is correlated with perceived comprehensibility and intelligibility, a strong foreign accent does not necessarily reduce the…
