See also:  SR-related TS/TR    

This TR provides information on the recognition performance of the DSR Extended Advanced Front End conducted by speech recognition vendors IBM and Scansoft for the selection of a codec for Speech Enabled Services. The performance results are provided both as absolute word error rates for DSR and AMR-NB/AMR-WB on a range of extensive evaluation databases and as relative word error rate reductions when compared to both the AMR-NB and AMR-WB codecs.
