摘要
提出了一种应用语音倒谱特征参量的端点检测改进算法,对信噪比(SNR)从-10～20dB的带噪语音信号进行仿真实验,结果表明,所提方法能较为准确地检测到语音端点。
An improved voice activity detection method based on cepstral features is proposed. Simulation with a lot of noisy speech signals that ranging from -10 dB to 20 dB is made. The results show that the speech endpoints can be detected more accurately by proposed method in different SNR environments.
