Abstract: Speech segmentation is the process by which the listener divides up the continuous speech stream into linguistically significant units that can be used to access meaning. The research on the influencing factors of speech segmentation is significant in that it helps the learners to improve their segmentation skills and speech recognition capability. Some influencing factors in the process of speech segmentation, such as rhythm, pronunciation variation, word frequency, lexical chunk, perception strategy and memory strategy on speech segmentation by the analysis of their functions in this process, are explored.

Key words: speech segmentation, rhythm, pronunciation variation, lexical chunk, perception strategy, memory strategy, word frequency

摘要： 语流切分是听者依据句法和语义规则，将连续不断的语流切分为若干能被理解的信息单位的过程。研究语流切分影响因子对促进语流切分、提高话语听辨能力具有重要意义。本文通过对语言节奏、语流音变、语块、听辨策略、记忆策略、词频等影响因子的分析，揭示其在语流切分过程中的应用功能。
