This paper describes the development of a binaural version of the Auditory Image Model (AIM) [1] and speech recognition performance with monaural and binaural versions of AIM. It is argued that phase-locking information in the auditory nerve can enhance speech recognition in noise significantly, and that coincidence detection is preferable to cross-correlation for preserving phase-locking information during the construction of binaural auditory images.
