Abstract:	臨床觀察中曾提及失語症病人的句調有壓縮或擴張的現象；西方文獻針對非流利型病人的研究指出，此類病人基頻活動範圍較正常人狹窄。針對此一議題，本研究試圖檢驗漢語流利型與非流利型失語症病人之基頻活動範圍。我們並深入分析語句的長度與基頻範圍變化的關係，以及漢語普通話的聲調對基頻活動範圍所構成的影響。本研究實驗組有八名失語症病人，其中流利型與非流利型病人各四位。控制組爲四位健康的正常人。實驗者設計了四組長度不同的句子；每組句八，每句之目標字爲同一聲調，八句平均使用漢語普通話的四個聲調。受試者需將實驗者所呈現的句子唸出，所有語料均錄音並進行聲學分析。最後，將分析結果加以統計考驗。研究結果顯示：漢語流利型及非流利型兩組病人的基頻範圍與正常人組的差異，均未達顯著水準；然而，我們亦偵測到非流利型病人的基頻範圍有較正常值壓縮的跡象。語句長度效應顯示，句子長度的增加會導致基頻活動範圍的擴張。此句長與基頻範圍的互動，對Ryalls的構音困難說提出了有力反證。另一方面，漢語的聲調對基頻範圍的改變亦呈現主要效應；其主要影響來自於高降調，這個聲調導致基頻範圍比正常值擴大許多。 Clinically it has been reported that some aphasic patients display compression of intonation while some other patients exhibit exaggeration of intonation. The present study aims to clarify this controversy over fundamental frequency range (F0) by providing cross-linguistic data from Chinese fluent and nonfluent aphasics. Our research question is whether the excursion of F0 is significantly influenced by different subject populations sentence lengths or tones.The statistical analyses yield significant main effects for sentence length and tone but non-significant effect for subject category. The sentence main effect indicates that along with the increase in sentence length the range in F0 also enlarges. Post hoc comparisons reveal significant differences between high-falling tone and the other three tones which evidence the interplay of tone and intonation. On the other hand the non-significant effect indicates that Chinese aphasic patients both fluent and non-fluent are not impaired in planning the F0 excursion. Earlier studies on French and Norwegian aphasics detect more restricted F0 range for non-fluent patients. In the present work non-fluent patients do display compression of F0 range though the difference between them and normal controls regarding this feature fails to reach significance.
