Abstract

Methods, systems, and products are disclosed for creating a voice response grammar in a voice response server including identifying presentation documents for a presentation, each presentation document having a presentation grammar. Typical embodiments include storing each presentation grammar in a voice response grammar on a voice response server. In typical embodiments, identifying presentation documents for a presentation includes creating a data structure representing a presentation and listing at least one presentation document in the data structure representing a presentation. In typical embodiments listing the at least one presentation document includes storing a location of the presentation document in the data structure representing a presentation and storing each presentation grammar includes retrieving a presentation grammar of the presentation document in dependence upon the location of the presentation document.

Claims

10. A system for creating a voice response grammar in a voice response server, the system comprising:

means for creating, a plurality of presentation documents, 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;

wherein means for classifying a structural element comprises;

means for identifying a presentation attribute for the structural element;

means for identifying a classification identifier in dependence upon the presentation attribute; and

means for inserting the classification identifier in association with the structural element in the structured document; and

means for identifying presentation documents for a presentation, each presentation document having a presentation grammar including means for creating a data structure representing a presentation and means for listing at least one presentation document in the data structure representing a presentation, which includes means for storing a location of the presentation document in the data structure representing a presentation;

means for storing each presentation grammar in a voice response grammar on a voice response server including means for retrieving a presentation grammar of the presentation document in dependence upon the location of the presentation document, wherein;

the presentation document comprises a file in a file system on a content server;

the file has a location identified by a pathname;

means for storing a location of the presentation document in the data structure representing a presentation includes means for storing the pathname and a network location of the content server; and

means for retrieving a presentation grammar includes;

means for retrieving the presentation document from the content server in dependence upon the pathname; and

means for extracting the grammar from the presentation document.

19. A computer program product for creating a voice response grammar in a voice response server, the computer program product comprising:

a recording medium;

means, recorded on the recording medium, for creating a plurality of presentation documents, including;

means, recorded on the recording medium, for creating, in dependence upon an original document, a structured document comprising one or more structural elements;

means, recorded on the recording medium, for classifying a structural element of the structured document according to a presentation attribute; and

means, recorded on the recording medium, 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;

wherein means, recorded on the recording medium, for classifying a structural element comprises;

means, recorded on the recording medium, for identifying a presentation attribute for the structural element;

means, recorded on the recording medium, for identifying a classification identifier in dependence upon the presentation attribute; and

means record on the recording medium, for inserting the classification identifier in association with the structural element in the structured document; and

means, recorded on the recording medium, for identifying presentation documents for a presentation, each presentation document having a presentation grammar including means, recorded on the recording medium, for creating a data structure representing a presentation and means, recorded on the recording medium, for listing at least one presentation document in the data structure representing a presentation, which includes means, recorded on the recording medium, for storing a location of the presentation document in the data structure representing a presentation;

means, recorded on the recording medium, for storing each presentation grammar in a voice response grammar on a voice response server including means, recorded on the recording medium, for retrieving a presentation grammar of the presentation document in dependence upon the location of the presentation document, wherein;

the presentation document comprises a file in a file system on a content server;

the file has a location identified by a pathname;

means, recorded on the recording medium, for storing a location of the presentation document in the data structure representing a presentation includes means, recorded on the recording medium, for storing the pathname and a network location of the content server; and

means, recorded on the recording medium, for retrieving a presentation grammar includes;

means, recorded on the recording medium, for retrieving the presentation document from the content server in dependence upon the pathname; and

means. recorded on the recording medium, for extracting the grammar from the presentation document.
