FAQ
Does AI voiceover sound human?
Yes with oral scripts and clean assets. Formal essays sound robotic.
Can free AI voiceover go on YouTube?
Depends on license and platform rules. Always check commercial terms.
Why does mine sound robotic?
Long sentences, bookish wording, too much at once. Shorten and test again.
Will YouTube penalize AI voice?
YouTube targets low-value mass content and misleading videos, not synthetic voice alone.
