Spatial separation reduces inter-source confusion rather than restoring lost signal

Evidence

The fact that speech sources originate from different spatial positions can eliminate some confusion that arises from the simultaneous presence of multiple speech sources (Durlach et al. 2003 ). A further improvement can be seen for target speech presented in isolation, but otherwise manipulated identically as before (black squares in Fig. 3 ). These data show the inherent intelligibility of the sparse target speech, ruling out confusion from interfering speech. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1661
