| Abstract: | 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. |
