Abstract
An improved method and apparatus is disclosed which uses probabilistic techniques to map an input search string with a prestored audio file, and recognize certain portions of a search string phonetically. An improved interface is disclosed which permits users to input search strings, linguistics, phonetics, or a combination of both, and also allows logic functions to be specified by indicating how far separated specific phonemes are in time.

A method of using a search string comprising:
- specifying a search string, including
- specifying linguistic items to be searched for, and
- specifying a distance in time within which at least some of said linguistic items should occur in a media source;
- and
- searching for the search string in the media source, including
- determining a first quantity related to a probability that the search string occurred at a first time in the media source.
3 more elements

- and
- searching the audio source according to the accepted search string, including determining a quantity related to a probability that the search string occurred in the audio source.
