Suprasegmental features (i.e., features realized through pitch, volume, and/or duration changes) are particularly difficult for second language learners. This has led to the creation of many different methods of training, often employing the use of experimenter or instructor-created training materials. However, the use of authentic materials for…

While empirical studies have shown the beneficial role of observing and producing hand gestures mimicking pitch features in the learning of L2 tonal or intonational contrasts, mixed results have been obtained for the use of gestures encoding durational contrasts at the perceptual level. This study investigates the potential benefits of horizontal…

In this study, 118 native speakers of Japanese watched 48 separate video clips in which a teacher provided recasts on phonological or lexical errors to students in Portuguese, a language with which the participants were unfamiliar. In the video clips, six recast characteristics were manipulated: length, segmentation (segmented/whole), prosodic…

In this article we look at some of the structural properties of second language (L2) Japanese WH questions. In Japanese the WH words are licensed to remain "in situ" by the prosodic contiguity properties of the phrases which have no prosodic boundaries between the WH word and the question particle. In a rehearsed-reading, sentence…

Purpose: This research compared individuals from two first language (L1) backgrounds (English and Japanese) to determine how they may differ in their perception of Mandarin tones (Tones 1 vs. 2 [T1-T2], Tones 1 vs. 3 [T1-T3], Tones 1 vs. 4 [T1-T4], Tones 2 vs. 3 [T2-T3], Tones 2 vs. 4 [T2-T4], Tones 3 vs. 4 [T3-T4]) on account of their L1. Method:…

This dissertation investigates Voice Onset Time (VOT), which serves as an essential property for differentiating plosive consonants in L1 and L2 Mandarin Chinese. It surveys VOT variations and demonstrates that they are affected by several phonetic and phonological properties, e.g., lexical tone, place of articulation (POA), speech rate,…

This study examines whether Japanese native (L1) listeners can implicitly learn stress pattern regularities, not present in their L1, after a brief auditory exposure. In the exposure phase, the participants listened to and repeated words bearing stress patterned after Latin, but with a highly restricted consonant inventory. They performed a…

This study considers the role of L1 phonological influence in L2 English past tense morphology production by native speakers of Spanish, Mandarin, and Japanese. While these L1s share similar phonological restrictions on consonant cluster formation needed for English past tense morphology, differences arise in L1 syntax (only Mandarin lacks…

This article extends Optimality Theoretic studies to the research on second language tone phonology. Specifically, this work analyses the acquisition of identical tone sequences in Mandarin Chinese by adult speakers of three non-tonal languages: English, Japanese and Korean. This study finds that the learners prefer not to use identical lexical…

The effects of repeated oral reading and timed reading on L2 oral reading fluency were examined among Japanese university students (N = 50) over 12 weeks. Three quasi-experimental groups were used in the study. Group 1 practiced two types of reading: Repeated oral reading with chunking practice and timed reading. Group 2 did timed reading only.…

This study investigates the relative impact of verbal expression and tone of voice when native speakers of English form an impression of non-native speech. Four expressions of inquiry uttered in two tones by non-native speakers were judged by native listeners and analyzed using an ordinal Probit model. Plain expressions received lower scores than…

The current study examined in depth the effects of suprasegmental-based instruction on the global (comprehensibility) and suprasegmental (word stress, rhythm, and intonation) development of Japanese learners of English as a foreign language (EFL). Students in the experimental group (n = 10) received a total of three hours of instruction over six…

Native language prosodic structure is known to modulate the processing of non-native suprasegmental information. It has been shown that native speakers of French, a language without lexical stress, have difficulties storing non-native stress contrasts. We investigated whether the ability to store lexical tone (as in Mandarin Chinese) also depends…

The current study longitudinally examined the influence of aptitude on second language (L2) pronunciation development when 40 first-year Japanese university students engaged in practice activities inside and outside English-as-a-Foreign-Language classrooms over one academic year. Spontaneous speech samples were elicited at the beginning, middle,…

This study examined factors affecting perception training of vowel duration in L2 Japanese with transfer to production. In a pre-test, training, post-test design, 48 L1 English speakers were assigned to one of three groups: auditory-visual (AV) training using waveform displays, auditory-only (A-only), or no training. Within-group variables were…
