zine-robotics/Basanti-AI-Chatbot ? reverse-engineered prompt

Build me a Python chatbot app called Basanti 2.0 that can chat with the user in a natural way, listen to spoken input, speak responses out loud, and handle basic intent based replies. It should have a simple knowledge base for answering common questions, plus a cleaner conversation flow so it can break down what the user says and respond sensibly. If it makes sense, also include the face detection and face tracking pieces as optional extras, so the app can react to a person being in front of the camera. Please wire the pieces together into one working experience, not just separate scripts, and make sure the code is organized enough that I can run the chatbot easily and test the main features. If you need to check current library docs online, go ahead and do that.
