基頻與噪音對華語自閉症兒童句子識別的影響：認知能力的角色

// Fundamental Frequency and Noise Effects on Sentence Recognition in Mandarin-Speaking Autistic Children: The Role of Cognitive Abilities

本研究探討基頻輪廓（F0）與背景噪音對自閉症兒童普通話句子識別的影響｜自閉症兒童在平坦基頻下識別率顯著降低，但在自然基頻條件下表現與同齡兒童相當，噪音對兩組均有影響｜工作記憶與語言智商僅在自然基頻時與識別表現相關，顯示自閉症兒童依賴完整韻律理解語句，建議結合韻律訓練與認知語言支持提升理解能力。

// This study investigated how fundamental frequency (F0) contour and background noise affect Mandarin sentence recognition in autistic children, examining verbal intelligence (VIQ), nonverbal intelligence (NVIQ), and working memory (WM) as predictors. Autistic children showed disproportionately reduced recognition accuracy with flattened F0 contours, though they performed similarly to typical peers with natural F0, and noise affected both groups equally. Within autistic children, WM and VIQ correlated with performance only when natural F0 contours were present, while no cognitive measures predicted accuracy with flattened contours. The findings suggest autistic children depend on intact prosody for comprehension, highlighting the need for interventions combining prosody training and cognitive-linguistic support.
