Studio-grade dubbing

One-click presets for every job

Fast Narration — one clear voice for explainers and voice-overs.
Balanced YouTube — the recommended all-round preset.
Dialogue / Acting — separate voices per speaker for conversations.
Cinematic Clone — clone the original speaker's own voice into the new language.
Voice Matching — auto-detects each speaker's gender for a natural fit.

Smart Tempo keeps the dubbed speech in sync — if a translated line runs long, it's gently sped up (capped at 2× to avoid distortion).
