Learners of a foreign language (FL) typically have to learn to process sounds that do not exist in their first language (L1). As this is known to be difficult for adults, in particular, it is important for FL pedagogy to be informed by phonetic research. This study examined the role of FL learners' previous linguistic experience in the processing…

As online automatic speech recognition (ASR) engines become more accurate and more widely implemented with call software, it becomes important to evaluate the effectiveness and the accuracy of these recognition engines using authentic speech samples. This study investigates two of the most prominent cloud-based speech recognition engines--Apple's…

This mixed-methods study examined the beliefs and performance of 10 adult Japanese speakers of English regarding the phenomenon of contraction in spoken English. Over the course of three months, a collective case study approach involving listening tasks and semi-structured interviews was employed to investigate the topic from multiple dimensions,…

This article describes an innovation in the teaching and learning of vocabulary in English as a Foreign Language classes. Whereas vocabulary coverage in classrooms and textbooks traditionally focuses on lists of target words in printed form, this article promotes the notion of "aural vocabulary" as an important part of…

This study examines common claims associated with shadowing. Studies in Japan conclude that shadowing is effective for improving learners' listening skills. Two common claims are that shadowing is effective for lower-proficiency learners and that it enhances learners' phoneme perception, thus improving listening comprehension skills. The former…

We examined the effects of presentation rate on speech perception in noise and its relation to reading in 117 typically developing (TD) children and 10 children with reading difficulties (RD) in Japan. Responses in a speech perception task were measured for speed, accuracy, and stability in two conditions that varied stimulus presentation rate:…

Infants' speech perception abilities change through the first year of life, from broad sensitivity to a wide range of speech contrasts to becoming more finely attuned to their native language. What remains unclear, however, is how this perceptual change relates to brain responses to native language contrasts in terms of the functional…

The current study investigated the impact of recasts together with form-focused instruction (FFI) on the development of second language speech perception and production of English /?/ by Japanese learners. Forty-five learners were randomly assigned to three groups--FFI recasts, FFI only, and Control--and exposed to four hours of communicatively…

The McGurk effect paradigm was used to examine the developmental onset of inter-language differences between Japanese and English in auditory-visual speech perception. Participants were asked to identify syllables in audiovisual (with congruent or discrepant auditory and visual components), audio-only, and video-only presentations at various…

The value of waveform displays as visual feedback was explored in a training study involving perception and production of L2 Japanese by beginning-level L1 English learners. A pretest-posttest design compared auditory-visual (AV) and auditory-only (A-only) Web-based training. Stimuli were singleton and geminate /t,k,s/ followed by /a,u/ in two…

Forty stutterers and forty nonstutterers in Japan were tested for susceptibility to delayed auditory feedback while reading passages under amplified delay conditions. Susceptibility was higher for stutterers than nonstutterers and for nonstuttering men than nonstuttering women. Stutterers appeared to rely on auditory feedback for speech control…

This annual report presents several articles related to the work of the Clinical Center for Child Development at Hokkaido University in Sapporo, Japan. The articles are: (1) "Joint Attention as a System Property of the Infant-Caregiver Interaction System"(Tsuneda Miho and Shing-Jen Chen); (2) "Age-Related Change in Japanese Maternal…

Discusses early detection of hearing impairment in Japan with particular reference to the system used in Tokushima Prefecture. Suggests that a required screening of all children at 18 months of age resulted in 2 developments: (1) all the hard-of-hearing children were identified; and (2) public health nurses became more alert to hearing impairment…

Discusses the Home Training Program for congenital hearing-impaired infants and their families administered by the Teikyo University Hospital. Suggests that the program is based on the maximum use of residual hearing, early identification of hearing impairment and early intervention, and support for parents. (AA)

Reports on the perceptual discrimination of segmental and suprasegmental phones by Japanese learners of English. Results reveal that early learners showed better discrimination performance than normal learners and confirmed the usefulness of learning English at an early age. (16 references) (Author/CK)
