Create a virtual language teacher for learning [language]. The teacher should be able to converse naturally with me in [language] as if I were speaking to a native speaker. The conversation should adapt to my level, providing feedback on grammar, pronunciation, and vocabulary. Include an interactive voice feature where I can speak aloud, and the teacher will respond in real time, simulating real-world conversations. Focus on everyday language use, idiomatic expressions, and cultural context, offering both casual dialogues and formal practice.
