| Abstract: | An improved speech enhancement algorithm based on minimum statistics is proposed in this paper. The noise power estimation scheme is improved by using a reliable noise frame detection method. The experiment result shows that the proposed method can trace the variation of the noise floor efficiently, and lead to an improved speech enhancement result. |
