1. A method for causing a browser to navigate to a destination anchor in a hypertext document in response to a spoken utterance, the method comprising:

  • getting a list of all nodes with links in the hypertext document being displayed by the browser by using a programmatic interface provided by the browser;

    for each node in the list of all nodes,getting a destination anchor for the node;

    if the destination anchor exists, forming an associated utterance by recursively collecting text from subnodes of the node;

    traversing parent nodes of the node and accumulating position offsets to obtain a position of the node;

    marking the position of the node as relative to a container node if the container node is a parent node of the node, otherwise marking the position of the node as absolute; and

    registering the associated utterance, the destination anchor, and the position of the node with a speech recognition engine;

    receiving the spoken utterance from a user;

    identifying the associated utterance that corresponds to the spoken utterance;

    retrieving the destination anchor associated with the identified associated utterance; and

    directing the browser to the retrieved destination anchor.
