How to Dub a Video: Methods, Tools and AI (2026)
Dubbing a video means replacing (or adding) a voice track so it can be understood in another language, or simply re-recorded cleanly. Whether you're a creator, trainer, or hobbyist, here are the methods for dubbing a video in 2026, from subtitling to AI voice, with the concrete steps.
Dubbing, subtitling, voice-over: what's the difference?
Before choosing a method, let's clear things up:
- Subtitling — you keep the original audio and display the translated text on screen. The fastest option.
- Voice-over — a narrator's voice is layered on top, without aiming for lip sync.
- Dubbing — you replace the voice with a new one, synced to the character's lips. The most immersive (and this is where the rythmo band comes in).
The methods for dubbing a video
1. Dubbing with a human voice
The classic method: a voice actor re-records the dialogue while following the picture. It delivers the most natural and expressive result. With a modern tool, recording happens directly online, with noise reduction — no studio required.
2. Dubbing with an AI voice
The fast method: a synthetic voice reads the translated text. Ideal for a mockup, a prototype, or large-scale dubbing. Quality has improved a lot, and it's perfect for previewing before a human recording.
3. Translated subtitles
If voice sync isn't essential, translating and displaying subtitles is the simplest and fastest option.
How to dub a video, step by step
Whatever the method, the workflow is similar:
- Import the video into an online dubbing tool.
- Transcribe the dialogue automatically (AI transcription).
- Translate into the target language if needed.
- Record a voice (human) or generate an AI voice in the new language.
- Sync the text/voice with the picture (the rythmo band helps here).
- Export the dubbed video, the audio (BWF), or the subtitles (SRT, ASS).
How to dub a YouTube video?
The principle is the same: import the video into the tool, transcribe, translate, then generate the voice or export subtitles that you re-import into YouTube Studio. For translation specifically, see our Translate a video online page.
