How to Create YouTube Videos Voiceover
Write or paste your video script, select a voice that matches your channel's energy, adjust the speed (slower for tutorials, faster for vlogs), and generate. Download the WAV and drop it into Premiere Pro, DaVinci Resolve, or CapCut.

Frequently Asked Questions
Can I monetize YouTube videos with AI voiceover?
Yes. Kokoro is Apache-2.0 licensed, which permits commercial use. Many successful YouTube channels use AI narration. Check YouTube's own content policies for any disclosure requirements in your region.
What's the best voice for YouTube tutorials?
Michael (male) and Emma (female) rank highest for tutorial clarity. Try both with a 30-second sample of your script to see which fits your channel.
How do I sync the voiceover to my video?
Import the WAV into your video editor, place it on a separate audio track, then adjust clip timing to match your visuals. Most editors auto-snap to the beat.
Can I generate voiceovers in multiple languages for one video?
Yes — generate separate clips in each language, then create language-specific versions of your video. Great for expanding international reach.
Is there a length limit per clip?
Each generation supports up to 5,000 characters (~750 words or ~5 minutes of audio). For longer scripts, split into sections and concatenate in your editor.
