Abstract: The present invention relates to systems and methods for adapting elements of a user interface of an interactive voice response system in a voice-based interaction based on rank of a user and more particularly to ranking user for their expertise. The method of ranking the user comprises a dialogue engine receiving information related to a plurality of attributes for a voice-based interaction. A user rank classifier determines user rank and updates a user model by a user model update component. Further, the dialogue engine adapts and provides the user with a user interface based on the user's rank corresponding to his expertise thereby, enhances engagement during interaction. This makes the interface more efficient, approachable and user-friendly. Moreover, it saves time and cost for both the system operations and the user.
