This study investigates the capacity for targeted hyperarticulation of contextually-relevant contrasts. Participants communicated target words with final /s/ or /z/ when a voicing minimal-pair (e.g., target dose, minimal-pair doze) either was or was not available as an alternative in the context. The results indicate that talkers enhance the durational cues associated with the word-final voicing contrast based on whether the context requires it, and that this can involve both elongation as well as shortening, depending on what enhances the contextually-relevant contrast. This suggests that talkers are capable of targeted, context-sensitive temporal enhancements.
本研究调查了对上下文相关对比进行有针对性的过度清晰发音的能力。当浊音最小对立体(例如目标词dose,最小对立体doze)在上下文中可用或不可用时,参与者用词尾的/s/或/z/来传达目标词。结果表明,说话者会根据上下文是否需要,增强与词尾浊音对比相关的时长线索,并且这可能涉及延长以及缩短,具体取决于什么能增强上下文相关的对比。这表明说话者能够进行有针对性的、上下文敏感的时长增强。
