Things to respect
Don't clone someone else's voice without permission, and use voices the platform licenses for commercial use when you're earning money.
Example of preparing a script for voiceover
Before: "Price 1,299.- free shipping BKK & vicinity"
After: "Only one thousand two hundred ninety-nine baht, with free shipping in Bangkok and the surrounding provinces."
Writing it out as spoken words helps the AI voice read correctly and sound much smoother.
Audio mixing tips

- Leave short silences between topics
- Use a few sound effects to emphasize key moments
