A Hybrid Architecture Using Cross-Correlation and Recurrent Neural Networks for Acoustic Tracking in Robots

 Audition is one of our most important modalities and is widely used  to communicate and sense the environment around us.  We present an auditory  robotic  system  capable  of  computing  the  angle  of  incidence  (azimuth)  of  a  sound source on the horizontal plane.  The system is based on some principles  drawn from the mammalian auditory system and using a recurrent neural net­  work (RNN) is able to dynamically track a sound source as it changes azimuth­  ally within the environment.  The RNN is used to enable fast tracking responses  to the overall system.  The development of a hybrid system incorporating cross­  correlation and recurrent neural networks is shown to be an effective mecha­  nism for the control of a robot tracking sound sources azimuthally.
