摘　　要：文章以山西交城方言为例,探究长时共振峰特性在方言与普通话之间进行语音同一性检验的价值;以普通话和山西交城方言为语料,4位男性和4位女性长时共振峰均值特征、长时共振峰分布特征、长时共振峰FFT功率谱特征、长时共振峰线性预测谱LPC特征共四方面的长时共振峰特性进行比较,得出长时共振峰特性在普通话和山西交城方言之间进行语音同一性检验的鉴定价值不高的结论。因此,在使用过程中不可单独作为认定同一的价值特征,长时共振峰线性预测谱LPC特征不可用于交城方言和普通话之间的语音同一性检验。The article takes Shanxi Jiaocheng dialect as an example to explore the value of the long-time formant features in testing the identity of Chinese mandarin and Shanxi Jiaocheng dialect.Based on Chinese Mandarin speech and Shanxi Jiaocheng dialect speech,four long-time formant features（ long-time formant mean value,long-time formant distribution,long-time formant FFT,long-time formant LPC） of four male speakers and four female speakers were calculated and analyzed.It is concluded that the value of formant feature is not valuable in testing the identity of Chinese mandarin and Shanxi Jiaocheng dialect.Therefore,it can not be used alone in forensic speaker identification.Long-time formant LPC can not be used in the speaker identification testing between Chinese mandarin and Shanxi Jiaocheng dialect.
