Abstract

Controls are provided for a web server to generate client side markups that include recognition and/or audible prompting. The controls comprise elements of a dialog such as a prompt, answer, confirmation, command and validation. An application control provides a means to wrap common speech scenarios in one control.

Claims

1. A computer readable medium having instructions, which when executed on a computer generate client side markup for a client in a client/server system, the instructions comprising:

a first set of visual controls having attributes for visual rendering on the client device;

a second set of controls having attributes related to at least one of recognition and audibly prompting; and

an application control for performing a selected task, the application control having properties for outputting controls of the second set to perform the selected task and associating the outputted controls with the first set of controls.

2. The computer readable medium of claim 1 wherein the selected task includes obtaining information.

3. The computer readable medium of claim 2 wherein the second set of controls includes means for defining a prompt generating markup for providing a question.

4. The computer readable medium of claim 3 wherein the second set of the controls provides means for defining a confirmation for generating markup related to confirming that a recognized result is correct.

5. The computer readable medium of claim 3 wherein the second set of controls includes means for defining a comparison to generate markup for comparing a recognized result with a selected value.

6. The computer readable medium of claim 1 wherein the second set of controls includes means for maintaining a recognized result apart from the associated control of the first set of controls, said means for maintaining associating the recognized result with the control of the first set of controls.

7. The computer readable medium of claim 6 wherein the means for maintaining the recognized result includes means for indicating that the recognized result has changed.

8. The computer readable medium of claim 6 wherein the means for maintaining the recognized result includes means for indicating that the recognized result has been confirmed.

9. The computer readable medium of claim 6 and means for maintaining a recognized result includes maintaining a set of items for corresponding recognized results, and wherein at least some of the items are individually associated with controls of the first set of controls, and wherein states are maintained for at least some of the items, the states including if the item is empty and if the item has been confirmed.

10. The computer readable medium of claim 2 wherein the application control includes a property that defines the format of input.

11. The computer readable medium of claim 10 wherein the input comprises at least one of alphabetical characters and numerical characters.

12. The computer readable medium of claim 11 wherein property defines ranges of allowable input.

13. The computer readable medium of claim 2 wherein the information obtained is a number.

14. The computer readable medium of claim 2 wherein the information obtained is numerical information in a selected format.

15. The computer readable medium of claim 2 wherein the information obtained is a calendar date.

16. The computer readable medium of claim 2 wherein the information obtained is a yes or no answer.

17. The computer readable medium of claim 2 wherein the task performed is to navigate a table of information.

18. The computer readable medium of claim 17 wherein the application control implements markup including receiving content commands to render information within the table.

19. The computer readable medium of claim 17 wherein the application control includes a grammar associated with the table.

20. The computer readable medium of claim 19 wherein the table includes a plurality of header fields and wherein the grammar is associated with the plurality of header fields.

21. The computer readable medium of claim 20 wherein the table further includes column headings and wherein the grammar is further associated with the column headings.

22. The computer readable medium of claim 17 wherein a set of navigation commands include at least one of a next command and a previous command.

23. The computer readable medium of claim 17 wherein the application implements markup including rendering possible choices to a user.

24. The computer readable medium of claim 17 wherein the application control implements markup including receiving navigation commands to update a position within the table.

25. The computer readable medium of claim 24 wherein the position identifies a particular row in the table.

26. The computer readable medium of claim 24 wherein the position further identifies a particular column in the table.

27. The computer readable medium of claim 24 wherein the table includes a plurality of rows, each row having at least one header field and at least one content field, and wherein the position identifies one of the plurality of rows.

28. The computer readable medium of claim 27 wherein the application control implements markup including rendering the header field of said one of the plurality of rows when a position is updated.

29. The computer readable medium of claim 27 wherein the application control implements markup including rendering the content field of said one of the plurality of rows upon receiving a content command.
