7. A system for synchronizing visual and speech events in a multimodal application, the system comprising at least one computer processor, at least one computer memory operatively coupled to the computer processor, and computer program instructions disposed within the computer memory configured for: calling a voice form of the multimodal application, wherein the multimodal application provides a multimodal web page to a client device over a network; receiving speech from a user; determining a semantic interpretation of the speech; calling a global application update handler of the multimodal application including exiting a voice form; identifying, by the global application update handler, an additional processing function in dependence upon the semantic interpretation; executing the additional processing function; updating a visual element after executing the additional processing function; updating a voice form after executing the additional processing function; and restarting the voice form after executing the additional processing function, wherein determining a semantic interpretation of the speech comprises determining a plurality of semantic interpretations of the speech, and wherein identifying, by the global application update handler, an additional processing function in dependence upon the semantic interpretation comprises identifying, by the global application update handler, an additional processing function for each of the plurality of semantic interpretations.

The system of claim 7 , wherein: receiving speech from a user comprises receiving an utterance from the user and recognizing the utterance of the user as a word of speech; and determining a semantic interpretation of the speech comprises assigning a meaning to the speech, wherein the meaning is applicable not only to the utterance received from the user but also to different words of speech.
