汉语拼音输入中韵律边界等级对相邻字母输入时间间隔的影响

The Influence of Prosodic Boundaries on the Time Interval between Pinyin Letters While Inputting Chinese Characters

由于同音字多,拼音输入不区分音调,导致拼音字母到汉字的转化并不唯一,从而降低了拼音输入法的输入效率。本研究基于汉语输入中的心理运动过程,探讨韵律边界对拼音字母输入时间间隔的影响。为此,我们分别采用自然篇章和歧义拼音字符串进行了两个实验,让被试以全拼方式输入指定汉语文本对应的拼音,记录相邻拼音字母的输入时间间隔。结果表明,拼音的韵律边界等级影响了拼音字母的输入时间间隔,等级越大,则输入时间间隔越长。

Due to the abundance of homophones and the lack of tone differentiation in pinyin input,the conversion from pinyin letters to Chinese characters is not unique,which reduces the efficiency of pinyin input method.Based on the psychomotor processes in Chinese input processes,this study explored the effect of prosodic boundaries on the time intervals of pinyin letter input.Hence,we conducted two experiments using natural passages and ambiguous pinyin strings(One ambiguous pinyin string can refer to 3 types of prosodic boundaries and Chinese characters.For example,the pinyin“xian”may refer to“现”在,“西安”and详“细安”排).Participants were asked to input the corresponding pinyin letters of our materials in full pinyin format,and the time intervals between adjacent pinyin letters were recorded.The results indicated that the prosodic boundaries of pinyin affect the time intervals of pinyin letters’input,with the higher-level prosodic hierarchy leading to the longer time intervals.
