1. A method comprising:
- processing, using a computer, a text source to form a multi-dimensional array of elements, wherein each element is indexed by at least a first dimension representative of a time frame of an audio representation of the text source and a second dimension representative of a phoneme state, and further wherein each element comprises a value that characterizes a probability associated with an occurrence of a phoneme state within a time frame of the audio representation of the text source;
receiving a search query via a text-based interface of a computer, an audio-based interface of a computer, or some combination thereof;
processing the query using a computer to generate a phonetic representation of the query; and
searching, using a computer, the multi-dimensional array of elements according to the phonetic representation of the query to locate one or more putative instances of the query in the text source.

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.
