本研究通过比较几类元音归一化方法在跨方言元音系统比较中出现的问题,发现整体空间类型的归一法基本不适用与跨方言元音比较,声道数据归一法和基频归一法则在实际操作中面临无法解决的困难。因此建议暂时可以把共振峰频率值转化成Bark值,并用统计平均的办法去除测量结果中的个体特征,然后再比较不同方言的元音系统。 In this study, by comparing the problems in the cross-dialect vowel system comparisons of several types of vowel normalization methods, it is found that the normalized method of the overall spatial type is basically unsuitable for cross-dialect vowel comparison. The rule of frequent return is faced with unsolvable difficulties in practice. Therefore, it is suggested that the value of the formant frequency can be temporarily transformed into the Bark value, and the individual characteristics in the measurement result can be removed by statistical averaging, and then the vowel systems of different dialects can be compared.
