Original language description
This paper describes an automatic system for processing and searching for large audio-visual archives, especially for the use of in the field of oral history studies. The system contains automated processing pipeline for speech recognition and indexation. The carefully designed graphical user interface allows to search for specific words and phrases. It also allows to search for out-of-vocabulary words and directly replay the occurrences sorted according to the automatically estimated confidence scores. The first archive processed in this system is the MALACH archive containing personal testimonies of holocaust survivors and witnesses. The searchable portion of interviews consists of 2,000 hours of English recordings and 1,000 hours of Czech recordings. The paper gives a brief overview of the architecture of the system, describes the phoneme-based search and provides basic performance metrics for both the English and Czech data.
