Effect of intensive audiovisual perceptual training on the perception and production of the /l/-/r/ contrast for Japanese learners of English

چکیده
This study investigates (a) the extent to which L2 learners use phonetic information from visual cues to improve the perception of a novel phonemic contrast following a course of intensive perceptual training, and (b) the impact of perceptual training on pronunciation. 62 Japanese learners of English were initially tested on their perception of the /l/-/r/ contrast in audio, visual and audiovisual modalities, and then undertook ten sessions of intensive training, before being tested again. Eighteen were trained using auditory stimuli, 25 using natural audiovisual stimuli and 19 using audiovisual stimuli combining a synthetic face with natural speech. All three groups of learners showed a significant benefit of training but learners with audiovisual training did not show greater improvement than listeners with auditory training. The ‘Auditory-training’ group improved their auditory perception of the sounds to a greater extent than the AV-training groups, and the AV (natural face) trainees improved their sensitivity to visual cues to a greater extent than those trained with auditory or AV (synthetic face) stimuli. The learners’ pronunciation of /l/-/r/ consonants improved significantly following perceptual training, with a greater improvement seen for those trained audiovisually with natural stimuli.

Effect of audiovisual perceptual training on the perception and production of consonants by Japanese learners of English
This study investigates whether L2 learners can be trained to make better use of phonetic information from visual cues in their perception of a novel phonemic contrast. It also evaluates the impact of audiovisual perceptual training on the learners pronunciation of a novel contrast. The use of visual cues for speech perception was evaluated for two English phonemic contrasts: the /v/–/b/–/p/ la...

This study investigates the extent to which L2 learners with different L1 backgrounds are sensitive to phonetic information contained in the visual cues to a novel phonetic contrast (labial/labiodental contrast), and the degree to which this sensitivity can be increased via intensive training. 36 Spanish-L1 and 47 Japanese-L1 learners of English were initially tested on their perception of the ...
متن کاملTraining Japanese listeners to identify English /r/ and /l/: long-term retention of learning in perception and production.
Previous work from our laboratories has shown that monolingual Japanese adults who were given intensive high-variability perceptual training improved in both perception and production of English /r/-/l/ minimal pairs. In this study, we extended those findings by investigating the long-term retention of learning in both perception and production of this difficult non-native contrast. Results sho...
متن کاملThe impact of visual training on the perception and production of a non-native phonetic contrast
Many studies have shown that the perception of ‘difficult’ non-native phonetic contrasts can be improved through auditory training. More recently, studies comparing the effectiveness of auditory and audiovisual training have shown an advantage for audiovisual training at least for contrasts that are sufficiently visually-salient. Audiovisual training also led to improvements in the pronunciatio...
متن کاملDoes Ultrasound Training Lead to Improved Perception of a Non-native Sound Contrast?: Evidence from Japanese Learners of English
Both the perception and production of speech sounds in a non-native language can be challenging to adult second language learners due to long-time experience with their native language. Numerous studies have investigated how the ability to perceive and produce speech sounds can be modified during adulthood. This study explores whether production training using ultrasound as visual feedback can ...
