Abstract

A method of generating an audio content index for use by a search engine includes determining a phoneme sequence based on recognized speech from an audio content time segment. The method also includes identifying k-phonemes which occur within the phoneme sequence. The identified k-phonemes are stored within a data structure such that the identified k-phonemes are capable of being compared with k-phonemes from a search query.
