Abstract
A system and method for interacting with content, such as web-based markup content, using visual and voice browsers. A first browser facilitates communication in a first mode (e.g., an HTML browser that facilitates visual/tactile interaction with HTML content), and a second browser facilitates communication in a second mode (e.g., a VXML browser that facilitates audio interaction with VXML content). HTML and VXML content is created that: (1) indicates a correspondence between HTML and VXML pages that represent the same underlying content; and (2) contains specialized tags that indicate information to be send from one browser to the other to synchronize each browser to equivalent parts of the content. The HTML browser is adapted to use relative links as signals that information is to be sent to the VXML browser, and the platform on which the VXML browser runs is adapted to recognize a “hit” on its own port 80 as a signal that information is to be sent to the HTML browser.
