摘　　要：背景噪声中的其他语音干扰在时域和频域上与有用语音完全混叠在一起,用普通的频分技术无法将其去除。本文从能量角度入手,利用调频-调幅模型和共振峰特征,滤除混叠在有用语音中的含绝大部分能量的元音干扰。最后对该方法在MATLAB中进行了仿真验证,并给出了仿真结果。Among the background noise, other speech interferences and the useful speech are absolutely overlapping in the time domain and frequency domain. The speech interference can not he removed by using an ordinary frequency division technology. In this paper, we start from the energy point of view, use AM-FM modulation model and formant frequency, to remove the vocalic interference which vast majority of energy in the useful speech. Finally, the method is simulated in matlab, and simulation results are given.
