Use strong, unique values for secrets + - Enable HTTPS in production + - Keep tokens and secrets in `.env` only -### Wake Word Detection +3. **Development** + - Use `.env.dev` for shared development settings + - Keep `.env` for personal overrides + - Enable debug logging in development -- Multiple wake words supported via comma-separated list -- Adjustable sensitivity (0-1): - - Lower values: Fewer false positives, may miss some triggers - - Higher values: More responsive, may have false triggers - - Default (0.5): Balanced detection +4. **Production** + - Use `.env.prod` for production defaults + - Set appropriate rate limits + - Configure proper logging + - Enable all security features -### Best Practices +5. **Testing** + - Use `.env.test` for test configuration + - Use mock tokens and endpoints + - Enable detailed logging for debugging -1.
