The manual workflow

Why does line-by-line voiceover take so long?

Your subtitles already contain the words and timestamps. Turning them into one usable voiceover track is the hard part.

1

Generating one line at a time

Each subtitle line needs its own voice clip before you can assemble a full track.

One subtitle file for the full voiceover
2

Aligning clips by hand

Longer lines can require speed changes or manual timeline edits.

Choose how the Studio handles long lines
3

Managing many audio clips

A collection of small files makes the video project harder to manage.

Frequently asked questions

Do I need to manually trim audio clips to match subtitles?

No! You can enable automatic speed adjustment so speech naturally fits within SRT/VTT timestamps. Review the audio before importing it into your video editor.

What subtitle formats are supported?

YupVox supports the most common subtitle formats: `.srt` and `.vtt`. You can also paste subtitle text directly into the studio.

Can I export the voiceover and use it in CapCut or Premiere Pro?

Yes! Download a standard high-quality MP3 file that you can drag straight onto the audio track in CapCut, Premiere Pro, or DaVinci Resolve.

Can I try subtitle dubbing for free?

Yes! Sign up with Google to receive 50,000 free trial credits immediately with no credit card required.
