    No transcript yet

    Press Transcribe to detect speech, speakers and word timings. Results are cached, so re-opening this project is instant.

    Translate

    Every line is fitted to its time slot — condensed instead of rushed. Watch along, edit any line, or re-translate one.

    Nothing to translate yet

    Transcribe your audio first — then translate it here.

    Voice generation

    Every line is re-spoken in the voice you choose for each speaker. Generate a quick draft first, then a final pass at higher quality.

      Design ’s voice

      Not a clone — a clean voice created from the traits you pick, then used for every line of this speaker. Accents shape English speech.
