Paper Abstract:
|
Recording lectures and putting them on the Web for access by students has become a general trend at various universities. To take full gain of the knowledge data base that is built by these documents elaborate search functionality has to be provided that goes beyond search on meta-data level but performs a detailed analysis of the corresponding multimedia documents. In this paper, we present some experiments we did towards setting up a Web-based search engine for audio recordings of presentations. We evaluate standard,
state-of-the-art speech recognition software as well as achievable retrieval performance. In addition, we compare the speech retrieval results with a traditional, text-based approach for searching to evaluate the value of speech processing for lecture retrieval. |
