Abstract

This paper shows an experimental study about the design of grammars for a voice interface system. The influence of the grammar design on the behavior of the voice recognition system regarding accuracy and computational cost is assessed through tests. With the redesign of a grammar we show that those characteristics can be expressively improved.
