Frequently Asked Questions
Translation converts words from one language to another. Dubbing goes much further — it localizes the content for the target audience. Different languages have different speaking speeds, idioms, and cultural expressions. Our AI adapts pacing so speech fits naturally into the original timing, localizes sayings and expressions instead of translating them literally, and clones the speaker's voice so it sounds authentic. The result isn't just translated words — it's a fully localized experience.
A typical 5-minute video takes about 5-10 minutes to process. Our AI handles transcription, localization, voice cloning, and mixing all in one pipeline.
Our AI clones the original speaker's voice — not just their sound, but their tone, emotion, and speaking style. The result is natural, expressive speech that feels like the original person speaking in a new language.
