Abstract
We report on our first experiences in dealing with the retrieval of spoken documents. While lacking the tools and the know-how for performing speech recognition on the spoken documents, we tried to use in the best possible way our knowledge of probabilistic indexing and retrieval of textual documents. The techniques we used and the results we obtained are encouraging, motivating our future involvement in other further experimentation in this new area of research. Supported by a "Marie Curie" Research Fellowship from the European Community.
