Abstract :
We describe a technique which is successful at discriminating speech from music on broadcast FM radio. The computational simplicity of the approach could lend itself to wide application including the ability to automatically change channels when commercials appear. The algorithm provides the capability to robustly distinguish the two classes and runs easily in real time. Experimental results to date show performance approaching 98% correct classification
