摘 要: 依据语音信号的频域特性,对其功率谱进行分析,提出了一种基于谱减法的端点检测算法,首先给出了算法的具体实现步骤,然后运用MATLAB软件进行了仿真。仿真结果表明,即使在较低信噪比(0~15dB)的情况下,采用本算法仍能准确地检测出语音信号的端点位置。 According to the features of frequency domain and analysis of power spectnum, a novel endpoints detection method is proposed based on spectrum subtraction theory. The realization procedure of this algorithm is demonstrated. The simulation is conducted using MATLAM software. Simulation results show that the endpoints of speeches can be detected at low SNR (5-15dB).
