Abstract：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 indicate 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.
