Abstract
An audio signal verification system is presented for verifying the sound is from a predetermined source. Various methods for analyzing the sound are presented and the various methods may be combined to vary degrees to determine an appropriate correlation with a predefined pattern. Moreover a confidence level or other indication may be used to indicate the determination was successful. The sound may be reduced to templates with varying degrees of richness. Also different templates may be created using the same sound source and different sounds from the same source may be aggregated to form a single template. Comparisons may be made comparing a sound or a template derived from that sound with stored sounds or templates derived from that stored sound. Moreover 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.
