Congrats on getting your project in front of everyone! Among many side projects I've never gotten around to start on, or past the hook up APIs stage, this concept is one of them. I suspect that is using one of the off the shelf NLP chat bots and speech recognition, perhaps from a platform like Hugging Face, since you are allowed to chat about anything you want and have a dozen or so languages enabled. While really cool, as others have pointed out in complex responses received, I suspect it is a long way for being useful to a language learner because the user has no way of knowing if what the chatbot is saying makes any sense. For example I used keyboard entry to speak in Japanese with it. The bot said hello and asked my name. I replied with my name in katakana and the desu (I am fragment) in hiragana. The bot responded in a way that just smashed those together as my name grammatically which is incorrect. Perhaps the language models can get so good some day one could just prompt a model to "teach me Japanese through conversation from the beginning", but for now I think it is difficult enough to make an engine for a single language pair. If one is far enough along in a language to be conversational, it is low-cost, or even free, to find an actual language exchange conversation partner.
