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.

First Claim:
Show all 8 claims
I claim:     1. A method for analyzing audio input events in a data processing system, wherein said data processing system utilizes a template to analyze audio input events, wherein said data processing system includes a peripheral device that generates said audio input event and an interrupt, said method comprising the steps of:
  • identifying a speech audio input event;
  • recording said identified speech audio input event;
  • processing said recorded speech audio input event to create a first entry in a template;
  • identifying a selected non-speech audio input event which occurs in a selected environment;
  • recording said identified non-speech audio input event;
  • processing said recorded non-speech audio input event to create a second entry in said template; and
  • thereafter, distinguishing between a speech audio input event and a non-speech audio input event by comparing said audio input event to said template in response to detecting said interrupt and detecting said audio input event within a preselected amount of time wherein said non-speech audio input event is identified.
