Voice changers aren’t just for gaming and live streaming anymore. In 2025, more creators, educators, and professionals are using AI voice changers to update pre-recorded videos—without going back into the studio.
Whether you mispronounced a word, want to improve tone, or need to localize your content in another language, the tools below can help you change a video’s voice without touching the original footage.
Here are the best voice changers specifically for editing voiceovers in pre-recorded videos, starting with one of the most flexible platforms available today.

1. AI Studios by DeepBrain AI
Best for script-based voice changes with lip sync
AI Studios is more than just a video maker—it’s a complete voice and avatar platform that allows you to edit what someone says after the video is made. You can change the voice, rewrite the script, or even translate it into another language, and the avatar or presenter will match the new voice perfectly with synced lips.
Key features:
- Modify any spoken line by editing the script (no re-recording)
- Change the voice to any of 80+ AI voices
- Use your own voice clone if you want it to sound like you
- Dub into 30+ languages with accurate lip sync
- Works with avatars and real video footage
- AI-powered proofreading lets you correct mispronounced words in seconds
Perfect for: YouTubers, educators, marketers, and anyone who wants to update or localize pre-recorded videos professionally without starting from scratch.
2. MyEdit by CyberLink
A browser-based audio editor that lets you change voices in recorded audio clips. You can upload your video’s audio track, apply preset effects (robotic, deep, childlike, etc.), and re-export.
Good for: Basic voice changes and noise removal in voiceovers.
Limitations: No lip sync, limited control over natural delivery.
3. Descript
Descript allows users to edit video audio like a Word doc. You can delete or change words in the transcript and it will regenerate the audio using your recorded voice or a stock voice.
Good for: Podcasters and solo creators correcting their own recordings.
Limitations: Requires initial voice training or uploaded audio track.
4. Kapwing Studio
Kapwing offers basic voice manipulation features inside its online video editor. You can upload a video, mute or replace audio, and add new voiceovers using AI-generated or recorded voices.
Good for: Fast, simple edits with drag-and-drop workflows.
Limitations: Limited voice customization and no automatic lip sync.
Why AI Studios Stands Out
Unlike other tools, AI Studios links your script directly to the speaker’s lip movement. When you update the voice, the mouth and facial animation adjust automatically—even if the avatar was already speaking in a previous version. It also allows for professional multilingual dubbing with synced visuals.
You don’t just change the voice—you change the entire message, tone, and language while keeping the visual flow of your video intact.
If you're looking for a video voice changer that works after the video is made, you're no longer stuck with complex editing or manual fixes. Tools like AI Studios give you full control over voice, script, tone, and language—while keeping your visuals sharp and synchronized.
Whether you need to fix a few lines, improve your delivery, or reach a global audience, these tools let you do it without ever hitting record again.
Make the edit. Pick the voice. Let AI do the rest.
