Subtitles to speech
Upload a subtitle file and we'll voice every line for you — keeping it in sync with the subtitle timings.

Check & edit the lines
Edit any line, hear it on its own, or give it a different voice. Lines you already voiced are reused when you generate.
Advanced options
AI reads the whole transcript and re-splits it at natural sentence boundaries (and tidies obvious caption typos), so the voice never breaks mid-idea. The wording stays yours.
Subtitles are usually cut mid-sentence for reading. Joining them back makes the voice sound far more natural.

One per line. Write term -> wording to fix how something is translated, or just the term on its own to leave it untouched.
Review & generate
Skim the translation (tap a line to fix it), pick a voice if you like, then generate. Changing voice or text and re-generating only takes a few seconds.
Tap a line's time to jump there. The line being spoken lights up as it plays.
We found several speakers and gave each a different voice. Tap ▶ to hear one, or change any.
Each line fills its original time slot to track the on-screen speaker.

Speech Music Ducking
Drag the highlighted part to move it, or its edges to trim. Press play to hear just that part.
Heads up: this plays the original speakers underneath the dub. Two voices at once is hard to follow unless you keep this well below the dub.
