Abstract: This paper describes the new ASR system developed by the LIUM and analyzes the various origins of the significant drop of the word error rate observed in comparison to the previous LIUM ASR system. This study was made on the test data of the latest evaluation campaign of ASR systems on French broadcast news, called ESTER 2 and organized in December 2008.
