Abstract:
A method for in a transaction environment executing a machine-controlled human-machine dialogue, said method comprising the steps of:receiving an access call;interrogating said access call in a dialogue structure by means of outputted speech items whilst examining subsequently received human speech items for ascertaining an actual transaction instance;generating said outputted speech items in accordance with said ascertaining until either attaining a positive transaction result, or otherwise exiting the dialogue in case of failure; andwherein said dialogue is constructed from callable subdialogues which constitute respective mutually independent building blocks wherein said subdialogues are stored in a hierarchy arrangement for generating a particular outcome if a positive result is attained by the subdialogue in question, wherein said subdialogues offer interfaces for mutual coupling with a hierarchically superior subdialogue, so that the overall structure is formed as based on a selection of subdialogues and exclusively based on required partial results by each of the subdialogues in the structure.
