Continuous time-frequency masking method for blind speech separation with adaptive choice of threshold parameter using ICA
Zbyněk Koldovský, Jan Nouza, Jan Kolorenč · 2006
We propose a novel method for blind speech separation using continuous time-frequency masking. The method is equipped with an adaptive choice of a threshold parameter that is based on utilization of ICA methods. We present a direct application that consists in the speech segregation for automatic transcription of spoken broadcasts disturbed by background music. Experimental results show improved performance in comparison with traditionally used binary masking methods.
