22. The interactive manual system of claim 12 , wherein the speech synthesis arrangement includes a text-to-speech (TTS) application.
12. An interactive manual system, comprising: a speech engine to receive and process speech from a user, convert the speech into a word sequence, and identify a structure to which the word sequence conforms; a structured manual including information related to an operation of a device; a visual model to relate a visual representation of the information; a dialog management arrangement to interpret the structure in a context and to extract pertinent information and the visual representation from the structured manual and the visual model, wherein the structure is categorized into one of a “how-to” meaning structure category and a “what-is” meaning structure category, each of the meaning structure categories characterizing the structures of its members as being of a single respective underlying meaning structure, different information being deemed pertinent for the extraction depending upon the meaning structure category into which the structure of the word sequence has been categorized; and an output arrangement to output the information and visual representation, wherein the structure manual and the visual model form a model package that includes a grammar package and a grammar table defined using a grammar specification language, wherein the model package further includes an objects file to define device model information that includes a model of at least one device component, wherein the object file is associated with at least one of a surrounding table, a slide table, a how-to table, and a what-is table, wherein the grammar package includes a set of phrases and sentences as grammars for the speech recognition engine to recognize, and the grammar table includes animation clips associated with the specified grammars, and wherein a categorization into the “what-is” meaning structure category causes the dialog arrangement to: determine an object in the “what-is” meaning structure; determine an object identification of the object; search the surrounding table for information of adjacent objects based on the object identification; search the what-is table based on the object identification for a textual description associated with a feature of the object; and display the textual description when the associated feature is displayed.
