Some Experiments in Audio-Visual Speech Processing
Abstract. Natural speech is produced by the vocal organs of a particular talker. The acoustic features of the speech signal must therefore be correlated with the movements of the a...

Blind Instantaneous Noisy Mixture Separation with Best Interference-Plus-Noise Rejection
Abstract. In this paper, a variant of the well known algorithm FastICA is proposed to be used for blind source separation in off-line (block processing) setup and a noisy environm...
