Abstract

A method for registering an utterance and an associated destination anchor with a speech recognition engine. The method includes getting a list of all nodes with links in a document being displayed by a browser by using a programmatic interface provided by the browser. For each node in the list of all nodes, the method gets a destination anchor for the node. If the destination anchor exists, the method forms the utterance by recursively collecting text from subnodes of the node. The utterance and the destination anchor a registered with the speech recognition engine.

Claims

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.

2. The method of claim 1, wherein forming the utterance further comprises recursively examining the subnodes of the node for alternate text and using the alternate text as the utterance if the collected text is blank.

3. The method of claim 1, wherein the parent node is temporarily made visible if the parent node is hidden.

4. The method of claim 1, further comprising adding a visible tag string in the vicinity of the position of the node and further registering the visible tag string with the speech recognition engine.

5. An article of manufacture comprising a computer-readable medium having a sequence of instructions, the sequences of instructions, when executed by a processor, causing the processor to perform 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;

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

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;

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.

6. The article of manufacture of claim 5, wherein forming the utterance further comprises recursively examining the subnodes of the node for alternate text and using the alternate text as the utterance if the collected text is blank.

7. The article of manufacture of claim 5, wherein the parent node is temporarily made visible if the parent node is hidden.

8. The article of manufacture of claim 5, wherein the method further comprises adding a visible tag string in the vicinity of the position of the node and farther registering the visible tag string with the speech recognition engine.

9. A speech recognition system comprising:

a document parser to get a list of all nodes with links in a document being displayed by a browser by using a programmatic interface provided by the browser;

a node parser to create a destination anchor for the node and, if the destination anchor exists, to form an associated utterance by recursively collecting text from subnodes of the node, for each node in the list of all nodes;

a position parser

to traverse parent nodes of the node,

to accumulate position offsets to obtain a position of the node, and

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

a registration engine to register the associated utterance, the destination anchor, and the position of the node with a finite state grammar controller to create a finite state grammar; and

a speech recognition engine

to receive a spoken utterance from a user,

to identify the associated utterance that corresponds to the spoken ufterance using the finite state grammar,

to retrieve the destination anchor associated with the identified associated utterance, and

to direct the browser to the retrieved destination anchor.

10. The speech recognition system of claim 9, wherein the node parser is to form the utterance by further recursively examining the subnodes of the node for alternate text and using the alternate text as the utterance if the collected text is blank.

11. The speech recognition system of claim 9, wherein the position parser is further to temporarily make the parent node visible if the parent node is hidden.

12. The speech recognition system of claim 9, further comprising a tag generator to add a visible tag string in the vicinity of the position of the node and the registration engine is further to register the visible tag string with the finite state grammar controller.
