For offline speech processing commands, the parameters {\tt translation\_\-rec\_\-params} and {\tt dialogue\_\-rec\_\-params} control, among other things, the number of N-best alternatives generated by Nuance. For example, the value \begin{verbatim} [package=callslt_runtime(recogniser), grammar='.MAIN', 'rec.Pruning=1600', 'rec.DoNBest=TRUE', 'rec.NumNBest=6']). \end{verbatim} produces a maximum of 6 hypotheses.

This command makes it possible to reduce the number of N-best hyptheses considered by language processing. Evidently, the number cannot be increased.
