    Publication number: 20040214555
    Abstract: A system for controlling of multiple kinds of modality in wireless telephones. A client controls modality on telephones which do not support simultaneous modality. This is done by suspending a browser when a voice command is detecting, storing the state of the browser, and then automatically restarting the browser when necessary. Another aspect operates in a simultaneous modality system and sends a context sensitive vocabulary to a voice server. This enables improved performance from multimodality, and also minimizes the amount of latency.
