Experimental study of fatigue degree quantification for multi-feature fusion identification

A comprehensive quantification method of fatigue degree is proposed concerning subjective and objective quantifications.Using the fatigue degree test software,fatigue degree is objectively quantified by analyzing the reaction and operation abilities of drivers about traffic signals.By comparison experiment with that EEG signal based,multivariate statistical analysis and fusion identification based on BP neural network(BPNN) results show that the experimental procedure is simple and practical,and the proposed method can reveal the correlation between fatigue feature parameters and fatigue degree in theory,and also can achieve accurate and reliable quantification of fatigue degree,especially under the associated action of multiple fatigue feature parameters.

从口语韵律的功能与分析看语音对立

本文从韵律功能切入语音现象,从对比的角度分析解释口语韵律,以解构汉语字调、小句调及英语词重音的声学与感知对比强度,并根据语流中焦点强调之分析结果,以音系之范畴对立思路试论形成对立的条件及意义。本文强调,分析语料需先就其特性,考虑分析单位及方法,厘清口语体中可预测信息及语言体系指派信息的关系,才能透视语言事实并提出正确的语音解释。
