| 摘 要： | 动态基频(F0)轮廓有助于嘈杂环境下的言语识别,可以作为将目标语音从背景声中分离的知觉线索。本研究通过评估老年人与年轻人在言语掩蔽下聆听具有自然动态F0轮廓与对F0轮廓操作调节后的汉语语句的言语识别能力,探讨老龄化对F0轮廓线索在汉语言语识别去掩蔽作用中的影响。结果显示,在言语掩蔽下自然动态的F0轮廓比压扁或拉伸的F0轮廓更能帮助年轻人抵抗信息掩蔽识别目标言语;而老年人在言语掩蔽下却难以从动态F0轮廓线索中受益。研究结果揭示了老年人利用F0轮廓线索促进掩蔽下言语感知能力的老化特点。

| Abstract: | Older adults encounter difficulty in recognizing speech in environments where multiple people are talking. Fundamental frequency (F0) contour is very important for speech recognition in daily communication and can serve as a perceptual cue to segregate speech from background noise. The effect of dynamic F0 contour cues on the speech recognition of younger adults in noisy environments has been widely studied, but the influence on older adults’ speech recognition, especially in tonal languages like Chinese, is still unclear. |
