摘　　要：本文通过对语音信号产生机制的分析,将分形维方法用于普通话孤立词语音信号起止端点的检测。实验中将分形维方法的结果与两种传统的语音端点检测方法进行了比较。实验结果表明,使用分形维方法对在实际的普通实验室环境下录制的孤立词语音进行端点检测不仅切实可行,而且还可以取得比传统方法更高的正确率。Based on analyses to the generation mechanism of speech signals , this paper presents a novel method which uses fractal dimension to determine speech terminals for mandarin isolated words. Compared with those of two traditional detection methods for speech terminals, the experimental results have shown that the use of fractal method in speech terminals detection for isolated words recorded in normal experimental environment is not only feasible, but it can also achieve higher correctness than traditional methods.
