Abstract

Methods, systems, and products are disclosed for creating a voice response grammar in a voice response server that include identifying a user for a presentation, the user having a user grammar, the user grammar including one or more user grammar elements and storing a multiplicity of user grammar elements for the user in a voice response grammar on a voice response server. In typical embodiments, identifying a user for a presentation includes creating a data structure representing a presentation and listing in the data structure at least one user identification. In typical embodiments, each grammar element includes an identifier of a structural element, a key phrase for invoking a presentation action, and a presentation action identifier representing a presentation action.

identifying the content type of the original document;

selecting, in dependence upon the content type, a full presentation grammar from among a multiplicity of full presentation grammars; and

filtering the full presentation grammar into a presentation grammar for the structured document in dependence upon the structural elements of the structured document.

11. The system of claim 9 wherein the user grammar comprises a multiplicity of user grammar elements for a content type, the system further comprising:

means for identifying presentation documents for the presentation, each presentation document having a content type; and

means for selecting user grammar elements according to the content type of the identified presentation documents;

wherein means for storing a multiplicity of user grammar elements for the user in a voice response grammar on a voice response server includes means for storing the selected user grammar elements in the voice response grammar.

12. The system of claim 9 wherein the user grammar comprises a multiplicity of user grammar elements, the system further comprising:

means for identifying presentation documents for the presentation, the presentation documents including structured documents having structural element identifiers; and

means for selecting user grammar elements in dependence upon the structural element identifiers;

wherein means for storing a multiplicity of user grammar elements for the user in a voice response grammar on a voice response server includes means for storing the selected user grammar elements in the voice response grammar.

13. The system of claim 9 wherein the user grammar comprises a multiplicity of user grammar elements, the system further comprising:

means for identifying presentation documents for the presentation, each presentation document having a presentation grammar including presentation action identifiers; and

means for selecting user grammar elements in dependence upon the presentation action identifiers;

wherein means for storing a multiplicity of user grammar elements for the user in a voice response grammar on a voice response server includes means for storing the selected user grammar elements in the voice response grammar.

14. The system of claim 9 further comprising creating a presentation document, including:

means for creating, in dependence upon an original document, a structured document comprising one or more structural elements;

means for classifying a structural element of the structured document according to a presentation attribute; and

means for creating a presentation grammar for the structured document, wherein the presentation grammar for the structured document includes grammar elements each of which includes an identifier for at least one structural element of the structured document.

15. The system of claim 14 wherein means for classifying a structural element comprises:

means for identifying a presentation attribute for the structural element;
