摘要
该文研究普通话双音节V1#C2V2中C2和V2对V1后过渡段的腭位以及F2轨迹的方向和变化幅度的影响。分别使用动态电子腭位和线性预测编码的方法获得V1后过渡段的腭位参数和F2轨迹。实验结果发现:1)V1的F2轨迹的变化与后腭接触面积的变化显著相关。2)C2为不同发音方式的唇音、舌尖中音和舌面后音时对V1的腭位和/或F2轨迹有显著影响。3)元音间逆向协同发音有2种情况:C2为唇音、舌尖中音和舌面后音的条件下,V2显著影响V1的腭位和/或F2轨迹;C2为其他发音部位的条件下,V2的圆唇特征显著影响V1的F2轨迹。实验结果表明:C2对V1以及V2对V1的影响受到C2舌体发音限制条件的制约,但是V2的圆唇特征对V1的影响不受C2发音限制条件的制约。
An electropalatographic and acoustic analysis was used to investigate the C2-to-V1 and V2-to-V1 anticipatory effects.The articulatory measures were obtained by the electropalatography（EPG） and the F2 trajectory by linear prediction coding（LPC）.The results show that： 1） the F2 transition is significantly correlated with the posterior contact index;2） a manner difference is found for linguapalatal contact and the F2 trajectory for V1 when C2 are labial,alveolar and velar consonants;3） the anticipatory vocalic effect is significant for the F2 transition and/or EPG parameters for V1 when the C2 are labial,alveolar and velar consonants.The rounded feature of V2 tends to spread onto the V1 off-glide which affects the F2 transition of V1.The article concludes that the anticipatory effects are constrained by the articulatory constraints on the tongue body for intervocalic consonants and that the rounding feature of V2 is independent in the coarticulatory process.
