Questions about YouTube voice-overs
Can I use the generated voice-over in a monetized video?
Commercial use depends on the selected model, voice, and source-data terms. Review the linked terms and any attribution requirements before publishing or monetizing the audio.
How should I generate a long YouTube script?
Split it into natural sections, generate and review each section, then join the WAV files in your editor. Shorter sections also make pronunciation fixes easier.
Does AIVoices upload my video script?
No. The supported models generate speech inside your browser. Your editing software and publishing platform may have their own data policies.
