从接受美学看朗读的对象感培养

接受美学强调文学欣赏和接受活动中读者的重要性，作为一个双向的交流活动，朗读同样必须关注接受者——受众的具体的期待和需求，这就是朗读中强调的对象感培养。朗读作品不仅要靠优美的声音、恰当的技巧去包装，更要与受众产生内心的交流与呼应。从朗读前的准备到朗读的过程，朗读者始终要把接受者“放在眼里”，“藏在心里”。这样才能真正达到用声传情、以情动人的感染效果。

以DSP实现基于概率DP匹配算法的说话人识别系统

提出了利用概率DP匹配算法进行说话人识别的的设想。并给出了运用TMS320C5416实现说话人自动识别系统的方案。该系统利用一种新的语音信号r阶的倒谱线性回归系数等参数构成识别的特征矢量集，运用提出的概率DP匹配算法进行与文本无关的说话人识别。实验结果表明该系统具有识别精度高、识别速度快，占用系统资源少等特点，是一种有效的说话人自动识别的实现方法。     

Street Smarts vs. Book Smarts: The Figured World of Smartness in the Lives of Marginalized, Urban Youth

How smartness is defined within schools contributes to low academic achievement by poor and racial/ethnic minority students. Using Holland et al.’s (1998) [Holland, D., Lachicotte, W., Skinner, D., & Cain, C. (Eds.) (1998). Identity and agency in cultural worlds. Cambridge, MA: Harvard University Press.] concept of “figured worlds,” this paper explores the “figuring” of smartness through the perspectives of marginalized youth. The youth made key distinctions between being book smart vs. street smart. This distinction is a direct challenge by the youth to the dominant discourse of smartness or “book smarts” as it operates in schools. To the youth, “street smarts” are more important because they are connected to being able to maneuver through structures in their lives such as poverty, the police, street culture, and abusive “others.” This distinction is key because street smarts stress agency in countering social structures whereas, for many of the youth, book smarts represented those structures, such as receiving a high school diploma. Implications for schools and pedagogy are discussed. B.A. earned from Indiana University – Bloomington, Masters and Ph.D. earned from University of North Carolina at Chapel Hill.

浅析口头交际中的明示与语境效果的获得

言语交际需要一定的语境效果;好的语境效果,有利于交际的顺延.口头交际中,语境效果的获得与发话人的明示有着直接的联系.面对不同的交际对象、交际场合,灵活变换明示方式,以期获得理想的语境效果,是发话人自然会(也必须)首先考虑的问题.本文仅从明示--推理的视角对此做了一些粗浅的分析.
