摘要

Abstract

In order to improve the accuracy of voice activity detection(VAD),an algorithm based on improvement of C0 complexity and Mel frequency cepstrum coefficient(MFCC)similarity is proposed. First,the C0 complexity and MFCC similarity of speech signal in each frame is calculated first,and then the comprehensive judgment is made in combination with the C0 com⁃plexity and MFCC similarity. VAD for noisy speech whose SNR ranges from ⁃15dB to 15dB is conducted. Matlab software is used for simulation experiment. The results show that the accuracy and stability of the proposed method is higher than only C0 complexity detecting method or MFCC similarity detecting method.
