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 $5, 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. Single-speaker videos with clear speech work best.
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.
