探討周邊聽覺敏感度、中樞聽覺因素與認知因素對縮時語音識別的影響

// Investigating the contribution of peripheral hearing sensitivity, central auditory factors, and cognitive factors on the recognition of time-compressed speech

本研究探討聽力、神經語音處理及認知對不同年齡及聽力族群理解快速語音的影響｜電生理與認知測試顯示，年長者腦幹訊號較弱但大腦皮質追蹤能力較佳，尤其在時間壓縮語音中｜聽力敏感度與處理速度為快速語音識別關鍵，且皮質處理主要輔助維持語音時間線索時的理解。

// This study examined how hearing ability, neural speech processing, and cognition affect understanding fast speech in different age and hearing groups. Electrophysiological and cognitive tests showed older adults had weaker subcortical encoding but stronger cortical tracking than younger adults, especially with time-compressed speech. Younger adults processed speech faster and recognized more highly compressed speech accurately. The findings indicate that hearing sensitivity and processing speed predict fast speech recognition, while cortical processes mainly aid recognition when speech timing cues remain intact.
