Abstract
A system and method for indexing segments of audio/multimedia files and data streams for storage in a database according to audio information such as speaker identity, the background environment and channel (music, street noise, car noise, telephone, studio noise, speech plus music, speech plus noise, speech over speech), and/or the transcription of the spoken utterances. The content or topic of the transcribed text can also be determined using natural language understanding to index based on the context of the transcription. A user can then retrieve desired segments of the audio file from the database by generating a query having one or more desired parameters based on the indexed information.
