### Note:
This is a simplified demo that:
1. Records your voice
2. Requires you to type what you said (in a real app, we'd use a Speech-to-Text API)
3. Translates the text to Chinese

For a production app, you would want to:
- Use a proper Speech-to-Text API (like Google Cloud Speech-to-Text)
- Handle more languages
- Improve error handling
