A software-based system and method that provides a generalized scheme to voice-enable text-oriented chatbots. The system can be configured to adapt to a plurality of different types of chatbots, a plurality of different speech-to-text and text-to-speech services, a plurality of different grammars, and even a plurality of different languages. The system can further be configured to handle “HTTP complex” situations such as electronic calendars by automatically analyzing these HTTP complex situations into various sub-dialogs, which the system can then automatically use to communicate with users, and then present the final results back to the chatbot. These methods enable organizations to preserve their extensive investment in legacy chatbots while rapidly and relatively inexpensively providing voice functionality to a broader range of users.
