ABSTRACT

Two experiments test how phrasal prominence influences listeners' perception of vowel contrasts and how prominence information and vowel formant cues are integrated in processing. Experiment 1 finds that listeners incorporate phrasal prominence in their perception of vowels, in line with how spectral structure is modulated by prominence in speech. Experiment 2 explores how prominence information is integrated with formant cues in a visual world eyetracking task. Prominence shows an overall later influence in processing in line with current models of prosodic and segmental integration. However, listeners' perception of formants was also impacted more subtly by prominence immediately in processing such that prominence information directly shapes how formant cues are perceived. Results are discussed in terms of their implications for models of prosodic effects in segmental perception and possible differences between prosodic prominence and prosodic boundaries in this regard.

摘要

两项实验测试了短语突出如何影响听众对元音对比的感知以及突出信息和元音共振峰在处理中的整合方式。实验1发现，听众在其元音感知中加入了短语突出，这与语音突出如何调制频谱结构相一致。实验2探索了视觉世界眼动跟踪任务中突出信息如何与共振峰线索相结合。根据当前的韵律和分段集成模型，突出显示了后期处理中的总体影响。但是，听众对共振峰的感知也会在处理过程中立即受到突出程度的影响，因此突出程度信息直接影响感知共振峰的方式。
