Abstract
A method and apparatus for analyzing audio input events. A template is utilized to analyze audio input events. A speech audio input event is identified. The identified speech audio input event is recorded. The recorded speech audio input event is processed to create a first entry in a template. A selected non-speech audio input event which occurs in a selected environment is identified. The identified non-speech audio input event is recorded. Then the recorded non-speech audio input event is processed to create a second entry in the template. Thereafter, a speech audio input event and a non-speech audio input event is distinguished by comparing an audio input event to the template.
