普通话鼻辅音与元音组合音节结构协同发音的声学研究

摘要

Objective To investigate acoustic characteristics of NV coarticulation in Mandarin.Methods This study compared nasal flow of 32 adult male’s NV production composed by /m-/、/n-/、/-/ and /a/、/i/、/u/、/ ə /.Results Vowels followed by nasal consonants can be nasalized. The nasalization of /n- /to /-v/ is greater than that of /m-/ to /-v/. When nasals around, the nasalization of /v/ firstly depended on the height, then on the the back or forth of the tongue.Conclusion The nasal flow of nasalized vowels could predict nasal hyperpituitarism or nasal hypopituitarism.%目的：探讨鼻辅音与元音组合音节结构协同发音的声学特点。方法比较32名成年男性/m-/、/n-/、/-/后接不同元音/a/、/i/、/u/、/ə/的鼻流量。结果 NV结构中后接元音会受到鼻声母/n-/、/m-/的顺向同化影响，/n-/对后接元音的鼻化程度大于/m-/；在鼻声母影响下，元音鼻化的程度取决于舌位的高低与前后。结论元音鼻化测量可作为鼻腔共鸣亢进或低下的重要诊断指标。
