普通话双音节V1n#C2V2音节间逆向协同发音

Anticipatory coarticulation in V1n#C2V2 sequences in Standard Chinese

该文使用动态电子腭位(EPG)研究普通话V1n#C2V2双音节中后续音节C2和V2对前鼻韵尾/n/以及V1的逆向协同发音影响。实验结果发现:C2舌前音和舌面后塞音决定前鼻尾的发音部位和舌形姿态,不存在V2对V1的逆向影响;C2为双唇音和舌尖中音条件下,存在V2对V1n的逆向影响,前者表现为从V1后过渡段开始舌体动作向V2过渡,后者只出现在鼻音时段后部;C2为舌面后擦音和唇齿擦音的时候,前鼻尾发音部位多未同化或部分同化,这可能与发音人的发音策略有关。该结果支持普通话辅音的协同发音阻力等级序列,同时能够为建立普通话发音生理模型奠定理论基础。

This study analyzes the anticipatory coarticulation of C2 and V2 on alveolar nasal coda /n/ and V1 in V1n#C2V2 sequences in Standard Chinese through electropalatography（EPG）.The results show that the articulatory place and tongue gesture of the alveolar nasal coda are determined by the following C2 with the anterior portion of the tongue and the tongue back being the primary articulator.Transconsonantal vocalic influence is not observed.The results also show that V2 affects the V1n when C2 is bilabial or alveolar consonants.In the former case,the tongue body gesture undergoes a smooth transition from V1 offglide to V2,while in the latter case the V2 effect occurs in the offglide of the nasal coda.When the following C2 is a velar or labiodental fricative,partial place assimilation or complete alveolar closure is found in the majority of tokens,indicative of the articulatory strategy used by the subject.The results support the scale of coarticulation resistance for consonants as a theoretical foundation for articulatory modeling of Standard Chinese.
