本研究探讨了语义语境、词汇知识和声学线索对连续语音切分的影响。听众听到了近似同音的短语（例如，plmpaI，表示“李子派”对“丰满的眼睛”）。实验的背景和声学线索被用来为一种分割选择（李子派）或另一种分割选择（丰满的眼睛）提供强有力的支持。词汇上有偏见的上下文倾向于一个分段或另一个分段（例如，skmpaI表示“scumppie”对 *“scumpeye”，lmpaI表示“lumpeye”对 *“lumppie”，星号表示词法上不可接受的解析）。一个强迫选择任务，在这个任务中，听众指出他们认为他们听到了两个词中的哪一个（例如，“馅饼”或“眼睛”），揭示了信息来源之间的补偿机制。当听觉线索较弱时，语音和词汇语境对切分反应的影响要大于听觉线索较强时。此外，词汇的影响伴随着减少的敏感性的声学线索。句子语境只影响听者的反应标准。结果突出了分级，互动和灵活的性质，多词分割，以及功能之间的差异，语料库和词汇的贡献，这一过程。
This study investigates the effects of sentential context, lexical knowledge, and acoustic cues on the segmentation of connected speech. Listeners heard near-homophonous phrases (e.g., plmpaI for "plum pie" versus "plump eye") in isolation, in a sentential context, or in a lexically biasing context. The sentential context and the acoustic cues were piloted to provide strong versus mild support for one segmentation alternative (plum pie) or the other (plump eye). The lexically biasing context favored one segmentation or the other (e.g., skmpaI for "scum pie" versus *"scump eye," and lmpaI, for "lump eye" versus *"lum pie," with the asterisk denoting a lexically unacceptable parse). A forced-choice task, in which listeners indicated which of two words they thought they heard (e.g., "pie" or "eye"), revealed compensatory mechanisms between the sources of information. The effect of both sentential and lexical contexts on segmentation responses was larger when the acoustic cues were mild than when they were strong. Moreover, lexical effects were accompanied with a reduction in sensitivity to the acoustic cues. Sentential context only affected the listeners' response criterion. The results highlight the graded, interactive, and flexible nature of multicue segmentation, as well as functional differences between sentential and lexical contributions to this process.
