Abstract
The present invention relates to creating a phonetic index of phonemes from an audio segment that includes speech content from multiple sources. The phonemes in the phonetic index are directly or indirectly associated with the corresponding source of the speech from which the phonemes were derived. By associating the phonemes with a corresponding source, the phonetic index of speech content from multiple sources may be searched based on phonetic content as well as the corresponding source.
Claims31
A method comprising:
- accessing an audio segment comprising speech content from a plurality of sources, wherein different speech segments of the speech content correspond to different ones of the plurality of sources;
- parsing the speech content into a sequence of phonemes wherein each phoneme corresponds to a basic unit of speech of the speech content;
- generating a phonetic index from the sequence of phonemes;
- and
- associating a corresponding one of the plurality of sources with phonemes in the sequence of phonemes of the phonetic index such that a source associated with a given phoneme or group of phonemes in the sequence of phonemes of the phonetic index is ascertainable.

A method comprising:
- accessing a phonetic index of a sequence of phonemes and associated source information wherein:
- each phoneme in the phonetic index corresponds to a basic unit of speech content of an audio segment comprising speech content from a plurality of sources, such that different speech segments of the speech content correspond to different ones of the plurality of sources;
- and
- the source information associates a corresponding one of the plurality of sources with the phonemes in the sequence of phonemes of the phonetic index;
- determining at least one phonetic search criterion in association with a search query wherein the phonetic search criterion corresponds to phonetic content;
- identifying a matching portion of the phonetic index that meets the at least one phonetic search criterion;
- and
- taking an action in response to identifying the matching portion of the phonetic index.
5 more elements
A system comprising:
- at least one communication interface;
- and
- a control system associated with the at least one communication interface and adapted to:
- access an audio segment comprising speech content from a plurality of sources wherein different speech segments of the speech content correspond to different ones of the plurality of sources;
- parse the speech content into a sequence of phonemes wherein each phoneme corresponds to a basic unit of speech of the speech content;
- generate a phonetic index from the sequence of phonemes;
- and
- associate a corresponding one of the plurality of sources with phonemes in the sequence of phonemes of the phonetic index such that a source associated with a given phoneme or group of phonemes in the sequence of phonemes of the phonetic index is ascertainable.
