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 database 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. |
