7. The method of claim 6 , further comprising: generating search graphs by the non-optimized composed weighted speech transducer.
7. The method of claim 6 , further comprising: generating search graphs by the non-optimized composed weighted speech transducer. 8. The method of claim 7 , wherein the search graphs are sub-optimal as a result of the non-optimized composed weighted speech transducer being generated by a minimization process performed on a non-deterministic transducer.
