Praat辅助可视化语音学习方式对中国二语学习者语音学习效果的实证研究

发布时间：2022-10-06 16:40

　　根据相关文献研究,可以发现二语学习者语音学习意识、所获得反馈及个体辨音能力差异或许是学习者二语语音改善重点需要关注的因素。结合当前现代教育技术发展的背景,本研究目的是对Praat辅助下,可提供视觉与听觉两种即时反馈的可视化语音学习方式在语音学习方面的效果进行探究。本研究主要通过两周的微语音学习（包括前测、干预学习、延时后测）,本族语者评分,问卷调查和访谈进行数据收集,从而拟回答下列问题:通过Praat辅助可视化英语语音学习,学习者的总分、音段、单词重音、语调与语速评分是否有显著提高?如果有,其分数变化在四个不同评分句是否存在差异?本文的主要研究发现如下:首先,通过比较学习者在Praat辅助可视化英语语音学习下,各项目前后测成绩,可以发现,学习者在总分、单词重音、语调与语速方面的评分有显著提高,而在音段方面没有统计意义上的显著提高。这可能是来自Praat辅助可视化英语语音学习方式本身特点与学习者母语的影响。此外,学习效果还存在个体差异。此外,经过Praat辅助可视化语音学习,学习者后测效果在不同评分句和不同评分项目上存在差异。学习者在评分句3（Were you at the party ...
