<p>The inventive system provides a user with a plurality of function choices based upon the communication device of the user. The system includes a device specific variable state transition model that formats the system functions into the function choices based upon a device of the user. Thus, if the user has a personal computer or other device with a large screen, the functions are formatted into a single level so that all of the functions are displayed simultaneously. If the user has a TDD or PDA or other device with a small screen, the functions are formatted into two or more levels, depending upon the screen size, so that only a manageable portion of the functions are displayed simultaneously. If the system lacks a screen, then the functions are formatted into a plurality of levels, each level having only a small number of function choices. The system uses a data base having key words that describe each function, and permutation lists that have expanded lists of phrases that are synonymous with the key words. The system uses a dialogue engine to compare the commands from the user with the key words and permutation lists to identify the requested function.</p> |
