Optimizaton and evaluation of sigmoid function with a priori SNR estimate for real-time speech enhancement
In this paper, an a priori signal-to-noise ratio (SNR) estimator with a modified sigmoid gain function is proposed for real-time speech enhancement. The proposed sigmoid gain function has three parameters, which can be optimized such that they match conventional gain functions. In addition, the join...
