    determining whether the Web page contains multi-modal components;

    sending the multi-modal components from the client to the speech recognition server (360) using a wireless packet streaming protocol connection;

    obtaining a grammar file or TTS markup strings by the speech recognition server (360) from a remotely located server using an established HTTP network connection (370) from URL references sent from the client;

    loading the received grammars in the speech recognizer for performing speech recognition and TTS markup strings into the speech synthesizer for producing synthesized speech; and
