AI voice changer for video

New voice. Same performance.

Change Voice swaps the voice in your video for a new one while keeping the original timing, pauses, emotion and delivery. The picture is untouched and the new voice lines up with every word, so the video still feels natural.

Same take, new voices
One recording, switched between voices. Turn the sound on to hear it.

Why it sounds natural

  • Timing kept

    Every word lands where it did, so lips, cuts and captions still match.

  • Delivery kept

    Pauses, emphasis and emotion carry over. Only the voice itself changes.

  • Compare voices

    Pick up to three voices in one run and keep the one that fits best.

  • Picture untouched

    The video stream is copied as is. Only the audio track is replaced.

  • Any language

    Works with speech in many languages, and keeps the language you recorded in.

  • Cleaner sound

    Optional noise cleanup removes room noise and music from the speech first.

Questions

How do I change the voice in a video?

Upload your video, pick a new voice from the library and click Generate. The speech is converted to the new voice with the same timing and delivery, and put back into your video.

Will the new voice stay in sync with my video?

Yes. The new voice follows the original speech word for word, with the same pauses and pace, so it stays in sync with the speaker's lips, your cuts and any captions.

What happens to background music and sound?

The new audio track carries the converted voice. With Clean up background noise on, room noise and music are removed from the speech first for the clearest voice. Add music back in your editor if you need it.

Can I try several voices?

Yes. Pick up to three voices in one run. Each one becomes its own video, grouped together in your history so you can compare them.

What do Voice match and Expression do?

Voice match sets how closely the result sounds like the new voice. Expression sets how much of the speaker's emotion and range is kept: more expressive keeps it lively, steadier evens it out.

How much does it cost?

Each voice costs 1 credit per started 15 seconds of video. You see the exact cost before you generate, and failed runs are refunded automatically.
