People are starting to see some very exciting multimodal applications, especially in the area of voice search. Today's multimodal voice search applications are available from companies like Tellme Networks, Google, and vlingo. Alternatively, one or more modality components or the interaction manager might run locally on a device. Today's Web and voice browsers have no direct way of receiving messages from an external component like the Interaction Manager. While future versions of HTML and VoiceXML might respond to external control messages, even with today's browsers techniques exist that can be used to simulate the ability to receive messages in straightforward ways.
