基于RFC模型的英语语调差异性研究

摘要

本文主要对英语语调差异性进行研究，分析中国英语语者与英语母语者语调差异性。对实验数据语音文件利用已建立的实验包通过MATLAB软件提取基频，基于提取的基频生成基频曲线。对得出的基频曲线基于上升/下降/连接模型（RFC模型）[]在起始位置斜度，结束位置斜度，基音频率均值，频域范围，语速五个方面参数方面进行研究。分别对中国英语语者和英语母语者就上述五个参数进行分析。实验数据表明基于RFC模型的语调差异性研究可行，中国英语语者和英语母语者在分析的5个参数上都有明显的差异。%The paper mainly researches on English intonation difference and analyzes the difference between English speakers in China and English-as-mothertongue speakers. Pitch is extracted from the experimental data in speech file on MATLAB and then pitch curve is generated based on the extracted pitch. Besides, the pitch curve is discussed based on raising/falling/connection (RFC model) from five parameters as starting slope, ending slope, average pitch, pitch range and speech speed. Also, the above mentioned parameters are analyzed for English speakers in China and English-as-mothertongue speakers. Experimental data show that the study of English intonation difference based on RFC model is feasible and there is great difference between English speakers in China and English-as-mothertongue speakers in the above parameters.
