Abstract
An archive system for records with an audio component, which uses automated speech recognition to create a multi-layered archive pyramid. The archive pyramid includes successive layers of data stored at varying data rates such as original video data, compressed video data, original audio, compressed audio data, recognized word-lattices, recognized word-bags and a global word index. The disclosed system uses automatic speech recognition to transcribe from audio to searchable index layers. During a search operation, automatic and semi-automatic techniques are used to search the archive pyramid from the smallest narrowest layers to the largest widest layers, to identify a moderate subset of records. This subset is further refined by a manual survey of regenerated compressed audio. Finally, the selected records are retrieved from the original audio archive layer.
