摘要：
In this study, we investigate to improve search speed and meanwhile guarantee robustness by a new method including 3 stages. Especially, in these stages, there is a kind of coarse retrieval method whereby the elements of features are tested to exclude mismatched points of a long audio signal at very high speed. Some tests have been implemented to compare with other methods with good performance. Experimental results demonstrate that the new method offers quicker retrieval speed and guarantees the robustness in additive noise environment. © 2010 Asian Network for Scientific Information.
