基于声学特征的阳声韵元音鼻化程度的计算研究

【摘要】：在以鼻音为韵尾的音节中,元音可能会受韵尾的鼻音影响而带上鼻化音色,该文在对阳声韵韵母声学特征物理分析的基础上提出了阳声韵元音鼻化程度的计算方法。利用元音鼻化段时长和鼻化元音共振峰带宽构建的一个三维向量作为描述鼻化元音的依据,把这个向量的模作为元音鼻化程度的标度。经过实验和计算,我们发现前鼻音韵母中的元音的鼻化程度比较低,标度均值0.410,而后鼻音韵母中的元音的鼻化程度比较高,标度均值0.718,在所有阳声韵中,韵腹是高元音的阳声韵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.
