【摘要】：在以鼻音為韻尾的音節(jié)中,元音可能會(huì)受韻尾的鼻音影響而帶上鼻化音色,該文在對(duì)陽(yáng)聲韻韻母聲學(xué)特征物理分析的基礎(chǔ)上提出了陽(yáng)聲韻元音鼻化程度的計(jì)算方法。利用元音鼻化段時(shí)長(zhǎng)和鼻化元音共振峰帶寬構(gòu)建的一個(gè)三維向量作為描述鼻化元音的依據(jù),把這個(gè)向量的模作為元音鼻化程度的標(biāo)度。經(jīng)過(guò)實(shí)驗(yàn)和計(jì)算,我們發(fā)現(xiàn)前鼻音韻母中的元音的鼻化程度比較低,標(biāo)度均值0.410,而后鼻音韻母中的元音的鼻化程度比較高,標(biāo)度均值0.718,在所有陽(yáng)聲韻中,韻腹是高元音的陽(yáng)聲韻元音鼻化程度最高的。
[Abstract]:In the syllable with nasal sound as the end, the vowel may be affected by the nasal sound of rhyme and take up the nasal tone color. Based on the physical analysis of the acoustic characteristics of the vowels, a method to calculate the degree of the nasal sound of the vowels is put forward in this paper. A three dimensional vector is constructed by using the length of the vowel segment and the bandwidth of the resonance peak of the nasal vowel as the basis for describing the nasal vowel, and the model of the vector is used as the scale of the degree of vowel rhinification. Through experiments and calculations, we find that the nasal degree of vowels in the vowels of the former nasal vowels is relatively low, with the mean scale of 0.410, and that of the vowels in the later nasal vowels is relatively high, with the mean of 0.718, in all positive rhymes. Rhyme ventral is the highest degree of nosing of the positive vowels of high vowels.
