Abstract: A system is provided to facilitate AI-based language learning. During operation, the system provides, on a computing device, a voice-based language learning partner chatbot. The system can construct a first prompt for a generative artificial intelligence (AI) engine to obtain language-teaching content from the generative AI engine, wherein the language-teaching content includes content based on a primary language and a secondary language. The system then delivers audio messages based on the language-teaching content to a user in a combination of the primary language and the secondary language, thereby allowing the user to learn the secondary language. The system further receives from the user an audio response message. The system then identifies a mistake made in the user audio response message and provides corresponding explanation in both the primary language and secondary language.
