Systems and methods for extracting meaning from multimodal inputs using finite-state devices
First Claim
1. A method of recognizing an utterance comprising:
- receiving an utterance comprising a first portion having a first mode and a second portion having a second mode;
generating, at a multimodal recognition system comprising a processor, a first mode recognition lattice and a first finite-state transducer based on the first mode; and
generating a recognition model comprising;
relating the first portion of the utterance to the second portion of the utterance using the first finite-state transducer; and
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.

Abstract
Multimodal utterances contain a number of different modes. These modes can include speech, gestures, and pen, haptic, and gaze inputs, and the like. This invention use recognition results from one or more of these modes to provide compensation to the recognition process of one or more other ones of these modes. In various exemplary embodiments, a multimodal recognition system inputs one or more recognition lattices from one or more of these modes, and generates one or more models to be used by one or more mode recognizers to recognize the one or more other modes. In one exemplary embodiment, a gesture recognizer inputs a gesture input and outputs a gesture recognition lattice to a multimodal parser. The multimodal parser generates a language model and outputs it to an automatic speech recognition system, which uses the received language model to recognize the speech input that corresponds to the recognized gesture input.
