Abstract(in English) We presents a noise suppression method for noisy factory environment. The proposed algorithm (Step 1) determines the voice signal or the noisy signal using VAD with spectrum entropy, (Step 2) estimate the noise variance using spectral subtraction, and (Step 3) perfom the colored driving source type Kalman filter for the desived signal estimation. The characteristic of this method is (1) Real-time processing for the low computational complexity and (2) high performance noise suppression without the conception of AR system. Numerical example show the effectiveness of proposed algorithm using Practical noise suppression using device.
