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.
