Five word-spotting experiments explored the role of consonantal and vocalic phonotactic cues in the segmentation of spoken Italian. The first set of experiments tested listeners' sensitivity to phonotactic constraints cueing syllable boundaries. Participants were slower in spotting words in nonsense strings when target onsets were misaligned (e.g., lago in ri.blago) than when they were aligned (e.g., lago in rin.lago) with phonotactically determined syllabic boundaries. This effect held also for sequences that occur only word-medially (e.g., /tl/ in ri.tlago), and competition effects could not account for the disadvantage in the misaligned condition. Similarly, target detections were slower when their offsets were misaligned (e.g., cittá in cittáu.ba) than when they were aligned (e.g., cittá in cittá.oba) with a phonotactic syllabic boundary. The second set of experiments tested listeners' sensitivity to phonotactic cues, which specifically signal lexical (and not just syllable) boundaries. Results corroborate the role of syllabic information in speech segmentation and suggest that Italian listeners make little use of additional phonotactic information that specifically cues word boundaries.
五项单词识别实验探究了辅音和元音音位结构线索在意大利语口语切分中的作用。第一组实验测试了听众对提示音节边界的音位结构限制的敏感度。当目标词首与音位结构确定的音节边界不一致时（例如，ri.blago中的lago），参与者在识别无意义字符串中的单词时比目标词首与音节边界一致时（例如，rin.lago中的lago）速度更慢。这种效应在仅出现在单词中间的序列中也成立（例如，ri.tlago中的/tl/），并且竞争效应无法解释不一致条件下的劣势。同样，当目标词尾与音位结构音节边界不一致时（例如，cittáu.ba中的cittá），目标检测比目标词尾与音节边界一致时（例如，cittá.oba中的cittá）更慢。第二组实验测试了听众对专门提示词汇（而非仅仅是音节）边界的音位结构线索的敏感度。结果证实了音节信息在语音切分中的作用，并表明意大利语听众很少利用专门提示单词边界的额外音位结构信息。
