Smith L & Fraser DS (2004) Robust sound onset detection using leaky integrate-and-fire neurons with depressing synapses. IEEE Transactions on Neural Networks, 15 (5), pp. 1125-1134. https://doi.org/10.1109/TNN.2004.832831
A biologically inspired technique for detecting onsets in sound is presented. Outputs from a cochlea-like filter are spike coded, in a way similar to the auditory nerve (AN). These AN-like spikes are presented to a leaky integrate-and-fire neuron through a depressing synapse. Onsets are detected with essentially zero latency relative to these AN spikes. Onset detection results for a tone burst, musical sounds and the DARPA/NIST TIMIT speech corpus are presented.
