aungmyintlwin/react-native-lingua ? reverse-engineered prompt

Build me a mobile language learning app like Duolingo, but with a real time AI voice teacher that users can actually talk to. I want a polished Expo React Native app for iPhone and Android, with a clean onboarding flow where people pick a language and set a goal, then sign in or sign up with Clerk.

The main experience should feel like a lesson based app with a friendly, modern UI, smooth navigation, and a strong focus on speaking practice. The AI teacher should listen and respond in real time using voice, so it feels like a live tutor instead of a chat bot. Make the app look good with a simple, playful style, and keep the code organized so the state is easy to manage.

If anything needs current setup details, look up the latest docs online. Also include basic analytics support and make sure the app is ready to run locally with a normal Expo workflow.
