How to Dub a Video into Another Language
AI dubbing translates your video's speech and regenerates it in a new language — preserving the original voice with voice cloning and keeping the background music intact. A 5-minute video takes about 5-10 minutes. Pay-as-you-go from $6, no subscription.
How It Works
Paste a YouTube URL or upload your video
Copy any public YouTube URL and paste it in — or upload a video or audio file (MP4, MP3, WAV). SpeakSwap extracts the audio automatically and supports solo videos, interviews, podcasts, and panels.
Pick your target language
Choose from 140+ languages. SpeakSwap auto-detects the source language, then transcribes, translates, and synthesizes speech in your chosen language. Voice cloning preserves the original speaker's tone.
Download the dubbed audio
Get a dubbed MP3 with the original background music preserved at full volume. Drop it into your video editor and sync to the original video, or use it standalone as a dubbed audio track.

Yes. SpeakSwap clones the speaker's voice — capturing their tone, pitch, and rhythm — and uses that voice to speak the translation. The dubbed audio sounds like the original speaker delivering the content in the new language.
Yes. SpeakSwap separates vocals from music, dubs only the speech, and remixes the dubbed vocals back over the original background track. The music, sound effects, and ambience are all preserved at full volume.
SpeakSwap's video dubbing starts at $6 for about 10 minutes of dubbed content — no subscription, credits never expire, and they work across all SpeakSwap tools. Sign up to get free starter credits.
Yes. In video dubbing, smart lip sync is optional for eligible clips longer than 20 seconds and up to 90 seconds. SpeakSwap detects speakers and recurring faces, then asks you to confirm speaker-to-face matches before rendering. It is designed for real talking-head video with visible, moving faces — not a still image, slideshow, or image-to-video animation. Transcription, text-to-speech, and other audio-only tools continue to work without lip sync.
Use real talking-head footage where a person is visibly speaking and the face moves naturally. SpeakSwap can dub a still-image video as audio, but it does not animate still pictures, slideshows, or image-to-video portraits. Turn smart lip sync off for those sources and use the audio dub instead.
