Dubbing needs translation matching utterance duration. Conditions. Research on English to French, Italian, German and Spanish with a public benchmark. Method. Isometric MT trains a transformer to produce output within about plus or minus 10% of the source in character count without N-best re-ranking; a companion paper compares verbosity control methods and reports subjective tests on dubbed clips. Practical use: set a length ratio target (about 0.9-1.1 of source characters) when prompting or selecting among translations, then fit residual difference with TTS rate (C3-B792-02) and pauses. Failure modes. Length control can cost translation quality; character count is a proxy for duration. Limitations.
