Subject: About speech and reverberation From: Katia Lebart <K.Lebart(at)SUSSEX.AC.UK> Date: Thu, 5 Nov 1998 09:33:03 +0000Dear List, I am currently in the last year of a PhD. I have been working on signal processing techniques for speech dereverberation. One of the methods I have developed is a monaural algorithm that uses the exponential decay of reverberation to attenuate late reverberation. In other words, reverberation is cancelled out thanks to the fact that it is a noise comodulated by an exponential decay. I am quite a layman in psychoacoustics or auditory perception. However, I would like to know more on the psychoacoustical plausibility of such a system. I would be very interrested in any opinion, comment, reference, data, about this, and in particular about the possible links between speech perception in reverberation (performance or mechanisms) and amplitude comodulation masking release or auditory grouping on the principle of "common fate" (in this case common amplitude modulation). I am looking forward to hearing from you, Thanks in advance for your help, Katia Lebart University of Sussex, England - ENSTBr, France Tel: (00-44) 1273-606755 (University) Ext. 4271 Fax: (00-44) 1273-678452 Email to AUDITORY should now be sent to AUDITORY(at)lists.mcgill.ca LISTSERV commands should be sent to listserv(at)lists.mcgill.ca Information is available on the WEB at http://www.mcgill.ca/cc/listserv
