The goal is achieved by considering only a database fraction as small as possible during the retrieval process. Our approach is based on a new clustering technique and comparisons with other clustering methods presented in the literature are performed. Our algorithm is shown to outperform the other techniques: retrieval performances close to those obtained with the whole corpus are achieved by selecting only 5\\% of the data.}, pdf = {https://publications.idiap.ch/attachments/reports/2004/rr04-02.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2004/rr04-02.ps.gz}, ipdmembership={speech}, }
