LOCATION VERIFICATION SYSTEM USING SOUND TEMPLATES

A system using sound templates is presented that may receive a first template for an audio signal and compares it to templates from different sound sources to determine a correlation between them. A location history database is created that assists in identifying the location of a user in response to audio templates generated by the user over time and at different locations. Comparisons can be made using templates of different richness to achieve confidence levels and confidence levels may be represented based on the results of the comparisons. Queries may be run against the database to track users by templates generated from their voice. In addition, background information may be filtered out of the voice signal and separately compared against the database to assist in identifying a location based on the background noise.
