Isi artikel

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.
