河南通许方言单字音声调音高的实验研究

The Experimental Study on the Pitch of Monosyllabic Tones in Tongxu Dialect

河南通许方言属于北方方言的中原官话区。通许方言的调类与普通话相同,但调值与普通话存在较大差异。本文借助Praat软件,运用实验语音学的研究方法,对通许方言母语者进行录音实验,提取单字音声调音高特征,在语音格局的理论框架下,对数据进行基频归一化处理。根据声学实验数据和五度标调法确定,通许方言四个调类的调值分别是阴平24、阳平51、上声44、去声31。

Tongxu dialect belongs to the central plains mandarin of northern dialects.Tongxu dialect has the sametone categories with Mandarin while the tone valuesare quite different from those of Mandarin.With the help of Praat software and the research method of experimental phonetics,this paper carries a recording experiment and extracts the tone pitch characteristics of monosyllabic tones.Then the data processing is performed with the fundamental frequency normalization under the theoretical framework of Speech Pattern.Finally,according to the acoustic experimental data and the Five-degree Scale Method,the four kinds of tone value of Tongxu dialect are Level tone(24),Rising tone(51),Falling-rising tone(44),Falling tone(31).
