The following technical report is available via FTP/WWW: ******************************************************************** "A Comparison of Auditory and Blind Separation Techniques for Speech Segregation" Technical Report #15, June 1999 Department of Computer and Information Science The Ohio State University ******************************************************************** Andre J. W. van der Kouwe, The Ohio State University DeLiang L. Wang, The Ohio State University Guy J. Brown, The University of Sheffield A fundamental problem in auditory and speech processing is the segregation of speech from concurrent sounds. This problem has been a focus of study in computational auditory scene analysis (CASA), and it has also been recently investigated from the perspective of blind source separation. Using a standard corpus of voiced speech mixed with interfering sounds, we report a comparison between CASA and blind source separation techniques, which have been developed independently. Our comparison reveals that they perform well under very different conditions. A number of conclusions are drawn with respect to their relative strengths and weaknesses in speech segregation applications as well as in modeling auditory function.
