In this paper, we propose a novel algorithm for the separation of speech mixtures using two-microphone recordings, based on the combination of improved independent component analysis (ICA) and ideal binary mask (IBM). The improved FastICA algorithm reduce the number of Jacobian matrix, significantly reduce numbers of the convergence of the iteration. The basic signals are afterwards improved by the...
In this paper, a spectral subtraction speech enhancement technology based on fast noise estimation is studied. Experiments show that this algorithm can significantly improve the performance compared to the basic spectral subtraction algorithm. This algorithm can estimate the noise power spectrum quickly in nonstationary noise environment and it has an easy implementation and small amount of calculation.
