英语学习者口语中话题结构上的韵律实现——一项基于英语即兴演讲的实证研究. /c夏志华.
// Foreign language teaching and research. 2013, Vol. 45, No.3.
// 外语教学与研究 2013, 第45卷.第3期 2013.tr. 398-410. This research looks into 19 spontaneous speeches to find out how prosody correlates with the topic structure in Chinese EFL learners’ speaking in terms of 5 prosodic parameters, which belong to three categories: pitch, durational prosody and speech-rate. The findings are as follow: In terms of pitch, learners are capable of making use of the pitch reset to match the beginning or end of the topics; there are supra-declinations within independent topic units; but the prosodic features, including onset pitch, final pitch, the pitch range and speech rate, which are used by English native speakers to match the different topic transitions, are not used similarly by Chinese EFL learners. In terms of durational prosody, learners can match the length of pause before topic units with some types of topic transitions, almost like native speakers, but with room for improvement. In terms of speech-rate, learners show the biggest difference from native speakers. On the whole, learners make simple use of prosodic parameters to mark the topic structure and need to make a big effort in this respect.
