指数函数规整群时延的VAD特征研究

Abstract

Abstract:

Although the robustness to noise of group delay function (GDF) was proved,the spiky effects caused by the resonance seriously undermined its further application.The ability to represent the original acoustic space was by no means guaranteed for the current improvement solutions.On the premise reducing the information loss in the process of feature extraction and aiming at decreasing its dynamic range,the feature of exponent function warping group delay function was produced.The test experiments of voice activity detection indicate that the robustness and detection accuracy is raised remarkably compared to the present GDF versions.

Key words: speech signal processing, voice activity detection, exponent function warping, group delay function
