Manual dubbing costs $500+ per video. SpeakSwap does it in 5 minutes with AI that clones the original voice and preserves the background music. Try a clip free, then $10 for about 16 min of dubbing (no subscription).
State-of-the-art AI dubbing samples
These are random clips run once through the pipeline, without hand-picking the best take or manually cleaning up the translation.
We're going to talk about data types, variables, constants, structures, conditionals, loops, functions, and classes here.
OriginalVamos a hablar aquí de tipos de datos, de variables, de constantes, de estructuras, de condicionales, de bucles, de funciones y de clases.
So, we're going to understand—and now I'm actually going to code it—what all these concepts are about.
Paste any YouTube video URL. We automatically detect the spoken language.
Select from 140+ languages. Our AI adapts pacing and tone to sound natural in the target language.
Our AI localizes the content — cloning the original voice, generating expressive speech, and mixing it seamlessly with the background music.
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. Longer videos take longer, but the pipeline is built for creator content: transcription, localization, timing calibration, voice cloning, and final mixing all run together so translated speech stays aligned with the original video.
Our AI clones the original speaker's voice across all 140+ supported languages — 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.
We support 140+ languages including English, Spanish, French, German, Japanese, Korean, Chinese, Russian, Arabic, Hindi, and many more. Our top-tier voices cover the 9 most popular languages with the highest quality.
Yes! Our AI cleanly separates speech from music, dubs only the spoken parts, then mixes the new voice back with the original background audio — so nothing is lost.

It works best with a single primary speaker. Multi-speaker videos can still be processed, but we use one cloned voice profile, so overlapping or rapid back-and-forth lines may assign parts to the wrong speaker.
