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.
