EFL英语语音可理解度的影响因素研究

通过对90名受试学生的英语录音进行语音可理解度实验，发现EFL英语语音的可理解度对语境具有很强的依赖性，在零语境条件下的语音可理解度不到0．6。进一步研究发现有8类语音“错误”在低语境条件下影响语音可理解度。结合声学分析来看，这些错误均涉及音段的质变，而语音“偏误”由于对音段没有质的改变，在一定语境的作用下，没有发现其对可理解度产生直接影响。语调、节奏、停顿等超音段因素的某些次标准特征有时容易对听者产生误导，使其在理解时需要付出较大的努力，若是在有一定的语境和允许听3遍的实验条件下，并不至于导致理解失败。

A Study of the Factors Affecting the Intelligibility of Chinese Students~ English

In an intelligibility experiment on the records of 90 subjects, the author found that the intelligibility of EFL＇ s English was heavily relied on context. The intelligibility of the subjects was less than 0. 6. The author went further study and found that 8 types of pronunciation ＂errors＂ were detrimental to intelligibility. Referred to acoustic analysis, the author discovered that all the 8 types of errors involved with qualitive segmental changes,which is distinct from ＂sub-standard pronunciation features＂ that are not involved with qualitive segmental changes and were found innocuous to intelligibility under context effects. Some sub-standandard features of suprasegmental factors such as intonation, rhythm, and of pause would mislead the listeners occasionally, and consequently more efforts were needed in the comprehension. However, on condition that 3 times of listening were allowed in the experiment, these factors were not severe enough to result in intelligibility breakdowns.
