Abstract
We use a two-layered unsupervised bio-inspired neural network to segregate sound sources, e.g. double-vowels or vowels intruded by nonstationary noise sources. The network consists of spiking neurons. The spiking neurons in both layers are modeled by relaxation oscillators. The first layer of the network is locally connected, while the second layer is a fully connected network. We show that in order to correctly segregate sound sources, we should either use Cochleotopic/AMtopic map (CAM) or Cochleotopic/Spectrotopic map (CSM) depending on the nature of the intruding sound source.
