摘要
基于小波变换,借助虚拟仪器平台构造了一种语音除噪的仪器系统,通过调用不同的小波基MATLAB算法和变换阈值系数控制实现了一般语音除噪的功能,仿真结果表明该系统具有良好的除噪效果。
Using wavelet transform, a instrument system for eliminating speech noises based on virtual instrument is designed. The system eliminates noises of speech with recalling various wavelet MATLAB algorithms and changing coefficients. The simulating results show the system has good performance of eliminating speech noises.
