The amount of audiovisual data in growing. Part of the data as lecture or conference recordings contain important information. However this information is hidden and unreachable for standard web crawlers as Google. This paper deals with a system, which makes the information available for standard text based indexers and searchers. It is done by conversion of speech and video into text. Description of the audiovisual indexing and search system is provided in the first part of this paper. We briefly describe the speech-to-text and slide synchronization components. Next, the description of an indexing engine is given. The engine is capable to index not only text but also timing and probability of recognized speech. The second part is aimed at practical issues like user interface and customer feedback.
