  1. 1

    The score survives

    Before anything is translated, Addavox separates the dialogue from the music and effects. Only the voices are replaced — the original score and sound design stay exactly as they were. It's the difference between a localized film and a hollowed-out one.

  2. 2

    Every word, timed

    Speech is transcribed with word-level timing and full punctuation, in the source language and ready for subtitles. Segment boundaries follow the actual speech, so nothing is clipped and no breath is mistaken for a word.

  3. 3

    Translated to fit the moment

    A line that takes four seconds in English rarely takes four seconds in Japanese. Addavox adapts each line for context, register, and the time it actually has — so the translation fits the moment it has to land in, instead of being crammed in or padded out.

  4. 4

    Spoken in their voice

    Generate each line in a preset voice, or in the speaker's own voice carried into the target language. Every line is matched to how that speaker sounded in that moment — falsetto, whisper, or full delivery. About five seconds of clean speech is all it takes.

  5. 5

    Fitted to the picture

    Lines land where they landed in the original. Pacing follows the original performance, pauses and all — and speech is never simply sped up to force a fit, because that's what makes a dub sound like a dub.

  6. 6

    Flagged where it matters

    Anything the system isn't confident about is flagged for a human, with the reason. You don't hunt for problems — you're told where they are.

  7. 7

    Yours to finish

    Open the editor and change anything: a word, a pause, a performance. Ask for changes in plain language. Bring in a native speaker to review one language without giving them an account. Then export — video, audio, subtitles, separated stems, or a single file carrying every language at once.

What you get back

MP4 video. MP3 audio as a full mix and a voice-only track. Subtitles as SRT and VTT in the source and every target language. The separated dialogue and music/effects stems. Or a single MP4 carrying the original audio plus every dubbed language as separate selectable tracks, subtitles embedded.
