Relatively few systems for machine hearing exploit top-down
information in source localisation, despite there being clear
evidence for top-down (e.g., attentional) effects in biological
spatial hearing. This paper addresses this issue by proposing
a framework for binaural sound localisation that exploits top-
down knowledge about the source spectral characteristics in the
acoustic scene. Information from source models is used to im-
prove the localisation process by selectively weighting binaural
cues. The system therefore combines top-down and bottom-
up information flow within a single computational framework.
Our experiments show that by exploiting source models in this
way, sound localisation performance can be improved substan-
tially under challenging conditions in which multiple sources
and room reverberation are present.
