目前关于鼻音的相关研究大致包括鼻化元音、鼻韵尾弱化和脱落、语流中鼻音的协同发音现象、古今鼻音的变化研究、普通话鼻音和其它语言鼻音的对比研究以及鼻音在教学方面的研究,研究方法早期多限于鼻音的定性分析,随着实验语音学的发展,研究方法则通过语图测量出共振峰、基频、时长、零极点、频谱等相关数据。本文主要对国内外鼻音研究现状作一梳理,从研究方法及研究内容两方面归纳总结前人对鼻音的研究方法及研究内容。
At present, the researches on nasal sounds generally include nasalized vowels, weakening and shedding of nasal constellations, synergistic pronunciation of nasal sounds in rhetoric, changes in ancient and modern nasal sounds, comparative studies of nasal and other nasal sounds in Mandarin and nasal sounds in teaching In the early stage of the research, the qualitative analysis of nasal sounds was mostly limited. With the development of experimental phonetics, the research methods measured the resonance peak, fundamental frequency, duration, zero-pole and frequency spectrum with the help of dialect. This article mainly reviews the present situation of nasal sounds research at home and abroad, summarizes the research methods and research contents of the nasal sounds from two aspects of the research methods and research contents.
