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

1. A method for creating a voice response grammar in a voice response server, the method comprising:

creating a plurality of presentation documents, including;

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

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

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 classifying a structural element comprises;

identifying a presentation attribute for the structural element;

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

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

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

storing each presentation grammar in a voice response grammar on a voice response server including 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;

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

retrieving a presentation grammar includes;

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

extracting the grammar from the presentation document.
