This paper addresses distant-talking speech recognition by means of remote sensors in a reverberant room. Recognition performances is investigated for different ways of initializing, steering, and optimizing the related beamformer. Results show how much critical that front-end processing may be in such a challenging setup, according to the different positions and orientations of the speaker.
