1. An apparatus for recognizing an utterance comprising: means for receiving an utterance, the utterance comprising a first portion having a first mode and a second portion having a second mode; means for generating a first mode recognition lattice and a first finite-state transducer, based on the first mode; means for relating the first portion of the utterance to the second portion of the utterance based on the first finite-state transducer; and means for generating a second finite-state transducer, the second finite-state transducer comprising a gesture and speech recognition model finite-state transducer, based on the first mode recognition lattice and the first finite-state transducer.
