本研究旨在探讨二语学习者是否可以通过训练来更好地利用视觉线索中的语音信息来感知一种新的音位对比。并评估了视听知觉训练对学习者一部小说对比音发音的影响。使用视觉线索的语音感知进行了评估的两个英语音位对比：/v/-/B/-/p/唇/唇齿对比和/l/-/r/对比。在第一项研究中，39名日本英语学习者进行了测试，他们的知觉/v/-/B/-/p/的区别在音频，视频和视听形式，然后进行了10次会议的听觉（“A训练”）或视听（“AV训练”）的知觉训练，然后再次测试。AV训练在改善唇/唇齿对比度方面比A训练更有效。在第二项研究中，62名日本英语学习者进行了测试，他们的感知/l/-/r/对比的音频，视觉和视听形式，然后进行了十届的感知训练，无论是听觉刺激（“A训练”），自然视听刺激（“AV自然训练”）或视听刺激与合成的脸同步自然语音（“AV合成训练”）。感知的/l/-/r/对比度提高，在所有的群体，但学习者培训视听并没有提高比那些训练courageorily。听觉感知改善最多的“A训练”的学习者和性能的唇读单独的条件下，改善最多的“自然AV训练”的学习者。知觉训练后，学习者的/1/-/r/发音有显著改善，其中“AV自然训练”组的改善更大。本研究表明，非母语音位对比的视觉线索的敏感性可以通过视听知觉训练提高。当音位对比的视觉线索足够显著时，AV训练比A训练更有效。看到说话者的面部表情也会导致发音的更大改善，即使是相对较低的视觉显著性的对比。(c)2005 Elsevier B.

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/ labial/labiodental contrast and /l/-/r/ contrast. In the first study, 39 Japanese learners of English were tested on their perception of the /v/-/b/-/p/ distinction in audio, visual and audiovisual modalities, and then undertook ten sessions of either auditory ('A training') or audiovisual ('AV training') perceptual training before being tested again. AV training was more effective than A training in improving the perception of the labial/ labiodental contrast. In a second study, 62 Japanese learners of English were tested on their perception of the /l/-/r/ contrast in audio, visual and audiovisual modalities, and then undertook ten sessions of perceptual training with either auditory stimuli ('A training'), natural audiovisual stimuli ('AV Natural training') or audiovisual stimuli with a synthetic face synchronized to natural speech ('AV Synthetic training'). Perception of the /l/-/r/ contrast improved in all groups but learners trained audiovisually did not improve more than those trained auditorily. Auditory perception improved most for 'A training' learners and performance in the lipreading alone condition improved most for 'natural AV training' learners. The learners' pronunciation of /1/-/r/ improved significantly following perceptual training, and a greater improvement was obtained for the 'AV Natural training' group. This study shows that sensitivity to visual cues for non-native phonemic contrasts can be enhanced via audiovisual perceptual training. AV training is more effective than A training when the visual cues to the phonemic contrast are sufficiently salient. Seeing the facial gestures of the talker also leads to a greater improvement in pronunciation, even for contrasts with relatively low visual salience. (c) 2005 Elsevier B.V. All rights reserved.
