ankit10000/voice-chat-ai ? reverse-engineered prompt

Build me a mobile app for chatting with an AI assistant by typing or talking. I want it to feel simple and polished, with a chat screen where I can send text messages, hear the assistant respond out loud, and use voice input to speak instead of typing.

Use React Native with Expo and TypeScript, and wire it up to Google Gemini for the AI replies. Add speech to text so I can press a button and дикtate my message, and text to speech so the app can read the assistant’s answers back to me. Make the UI clean and modern, with a nice chat layout, clear mic and send buttons, and obvious states for listening, thinking, and speaking.

Please set it up so it runs smoothly on Android and iPhone, and make sure the styling is consistent and responsive. If you need to check current docs for the Expo speech features, go ahead and look them up online.
