Video voice changer

Video voice changer for finished videos

MirrorVox replaces the spoken voice of a video you have already finished. The picture you edited stays exactly as it is — only the voice you hear is different.

MP4 and MOV, up to 3 minutes per video.

What it is

What a video voice changer does

A video voice changer replaces the voice you hear in a video without touching the video itself. MirrorVox does that on files you have already exported: it takes the spoken audio, generates the same delivery with the voice you selected, and returns the video with the new voice on it.

  • It works on a finished MP4 or MOV, not on a project file.
  • It replaces the spoken voice, not the music, the effects or the picture.
  • The voice can come from the MirrorVox library or from a voice you cloned.
  • It is not a video editor and it does not translate or re-write what is said.

Voice vs video

The voice changes. The video does not.

A voice change should not cost you the edit you already approved. MirrorVox works on the spoken audio and leaves everything else untouched.

  • The spoken voice is what changes.
  • The video image is untouched.
  • The original duration is preserved.
  • You download the result as an MP4.
  • No watermark is added to the result.

Voices

Hear the voice before you commit

Every voice in the library can be previewed first, so you choose with your ears instead of a name on a list.
