    摘要:

    由于语音学习的特殊性和复杂性,其研究相较于其他语言技能而言所受的关注一直较少。计算机辅助语言学习的出现,使呈现在电脑上的语音可视化成为可能。然而相关研究表明,虽然可视化的视觉反馈对语音学习有积极影响,多数研究却只关注了语音的超音段特性,对语音系统中其他部分未有涉及。本研究基于Praat语音可视化分析软件的使用,在语音教学中使用视觉反馈范式(Visual Feedback Paradigm,简称VFP),以语音强度比为检测标准,对学习者语音学习的情况进行了研究和分析,并得出了以下结论:1)利用VFP进行语音教学可取得比传统听觉训练更好的效果,且取得的语音改善具有一定的持久性;2)利用 VFP所获得的单词层面上的语音提升能够扩展到相似的话语(句子)层面上,并且这种提升也具有持久性。3)学生对于VFP持积极的评价,他们认为视觉反馈所提供的明显图像差异能反映出单个音素的相对音长与音强,从而为发音提供指导。本研究证明了VFP对于语音学习的有效性和概化性,以及利用VFP在二语语音课堂中的潜在实用价值。

    Abstract:

    Due to the particularity and complexity of English phonetic learning, English phonetic researches have received less attention compared with other language skills. The emergence of computer-assisted language learning makes speech visualization possible. However, relevant studies have shown that although visual feedback has a positive impact on speech learning, most studies only focus on the super-segmental features of speech sound, while other parts of the speech systems are not involved. Based on the use of Praat , a speech visual analysis software, this study used visual feedback paradigm (VFP) in speech teaching, and took the speech intensity ratio as the test standard to study and analyze the situation of learners’ speech learning, and made the following conclusions: First, using VFP in speech teaching could achieve better results than traditional auditory training, and the speech improvement achieved has continuous effect ; Second, the impact of VFP at the word level could be extended to similar utterance or sentence level, that is, generalizability, and the promotion is also persistent; Third, students make positive comments towards VFP. They believe that visual feedback provides obvious image differences and can reflect the relative length and intensity of individual phonemes, thus providing guidance for their pronunciation. This study demonstrates the effectiveness and generalization of VFP for English pronunciation learning, as well as the potential practical value of using VFP in lower-level second language speech classes.
