How to Dub a YouTube Video with LALAL.AI Voice Cloner: The Easiest Way

Clara -

If you want to expand your reach and connect with audiences who speak different languages, adding a voice-over to your videos is one of the most effective strategies. Essentially, you’re creating a dubbed version of your original content, allowing viewers who don’t understand the original language to enjoy and engage with your work.

Dubbing isn't just for movies or TV shows; it’s a powerful tool for a wide range of content, including educational tutorials, entertainment videos, product reviews, unboxing videos, cooking guides, travel vlogs, or even yoga and fitness lessons.

Traditionally, creating a dubbed version required access to professional studios, expensive recording equipment, and hours of editing to synchronize the new audio with the original video. Today, AI-powered tools like LALAL.AI have simplified this process dramatically. These tools allow you to separate voices from music, enhance audio quality, and even translate and record new voice-overs without any specialized equipment. That means you can produce high-quality, multilingual versions of your videos entirely from your computer, making it easier than ever to reach global audiences.

In this guide, we’ll take you step by step through the process of dubbing a YouTube video using a few useful tools. You’ll learn how to extract the original audio, clean it up, translate or record a new voice-over, and synchronize it perfectly with your visuals. By the end, you’ll have all the knowledge you need to make your content accessible to viewers around the world, boosting both engagement and impact.

What Is Video Dubbing?

Video dubbing is the process of replacing the original spoken audio in a video with a new voice track, often in a different language. This approach is widely used in film, TV, and online content to make videos more accessible.

Dubbing usually involves:

  • Reducing or removing the original speech while keeping background music and sound effects intact.
  • Recording a new voice-over, either by a human or through AI-generated speech.
  • Synchronizing the new audio with the speaker’s lip movements and the video’s timing.

Why Should You Dub Your YouTube Videos?

If you already use subtitles to reach international viewers, you may wonder if dubbing is worth it. Unlike subtitles, dubbing replaces the original audio with a new voice, creating a more immersive experience. Some key benefits:

  • Expanding your audience globally can increase ad revenue and attract international sponsors.
  • Videos are more likely to be shared and recommended when viewers understand them in their native language.
  • Offering dubbed versions shows your commitment to accessibility and inclusivity, which strengthens your reputation as a creator.

Just look at channels like MrBeast — all of his videos are dubbed in multiple languages.

Tip: With LALAL.AI, you can easily isolate vocals and create new voice tracks for dubbing.

3 Things to Think Through Before Dubbing a YouTube Video

Careful planning helps avoid common mistakes:

  1. Poorly executed dubbing can feel out of sync or unintentionally comedic. Every step matters if you want a professional result.
  2. The new voice track should match the original timing and speech pattern. This keeps dialogue aligned with visuals.
  3. Translate your script accurately before recording to ensure your message is preserved.

How to Dub a YouTube Video: Best 2 Ways

Option #1. Use YouTube Auto-Dubbing Feature

YouTube has introduced an automatic dubbing feature, enabling over 100,000 creators to share their content in multiple languages, including English, French, German, and Spanish, with minimal effort. Now, your viewers can enjoy your videos in their native language!

How It Works

  1. Upload your video as usual. This feature is still evolving as Google refines voice quality and naturalness.
  2. YouTube detects the spoken language and generates dubbed versions in several languages, such as French, German, Spanish, Hindi, and more.
  3. Viewers can select their preferred language from the track menu, and YouTube will remember it for future videos.
  4. AI-generated dubs are labeled so viewers know it’s machine-generated.

Option #2. Dub a YouTube Video Using Multiple AI Tools

Step 1. Download the Video or Just Audio You Want to Dub

To add a new voice-over, you need a copy of the video or audio. Tools like 4K Video Downloader Plus or similar can help you save the content in high quality:

  1. Install 4K Video Downloader Plus.
  2. Turn on the Smart Mode by toggling the bulb on.
  1. Copy the URL of the video you need.
  2. Click Paste Link in the app.
  3. Select the best quality and format for editing (MP4 is usually the safest bet) if you’re downloading a video.

If you wish to just save the audio, choose Audio in the Download option and then select the format.

  1. Click Download, and wait for the file to save to your device.

Once your video is ready, it’s time to work on the audio.

Step 2: Remove the Original Voice Track from Audio or Video with LALAL.AI

To replace a voice-over, you need a clean background track without speech. LALAL.AI can isolate vocals from music and effects.

How to remove vocals with LALAL.AI

  1. Open the LALAL.AI website.
  2. Upload the extracted audio or video file. Yes, LALAL.AI can work with videos as well.
  3. Choose Vocal & Instrumental stem to isolate the speech.
  4. Let the AI process your file, then download the instrumental-only version after previewing it.

Now, you have a video/audio with just background sounds, making it ready for your new voice-over.

Step 3: Record or Generate the Dubbed Voice-Over

You can either record manually or generate an AI voice:

Option 1: Record Your Own Voice

You can use tools like Audacity, Adobe Audition, or GarageBand. Don't forget about a quality microphone and match the tone and pacing of the original.

Option 2: AI Voice Generation

If recording a voice-over yourself isn’t feasible, you don’t have to worry; AI voice generation tools have made it possible to produce realistic, professional-sounding narration with just a few clicks. Platforms like ElevenLabs, Descript, or even LALAL.AI with its new Voice Cloner feature allow you to create high-quality voice-overs without a microphone or recording studio. All you need to do is provide a script or, in the case of voice cloning, a short sample of a voice, and the AI will generate a natural-sounding narration that matches your chosen tone, pace, and style.

These tools can capture the nuances of real human speech, including emotion, emphasis, and subtle inflections, making your dubbed videos feel authentic and engaging.

Step 4: Sync the New Audio with the Video

Once your new voice-over is ready, the next step is to sync it with your video. This is where a video editor comes in handy. Matching the timing of your narration to the visuals ensures your dubbed video feels natural and professional.

Recommended tools for syncing audio:

  • DaVinci Resolve – a free yet highly powerful editor suitable for precise audio-video synchronization.
  • Adobe Premiere Pro – a professional-grade option with advanced audio and video editing features.
  • Kapwing – a browser-based editor that doesn’t require installing software, ideal for quick edits and simple projects.

How to sync your voice-over:

  1. Import your assets – load both your video and the newly generated audio file into your chosen video editor.
  2. Mute or remove the original audio – this avoids overlapping speech and makes it easier to focus on syncing the new narration.
  3. Align the voice-over – adjust the timing so the new audio matches the speaker’s lip movements, gestures, or visual cues. Many editors allow you to zoom in on the timeline for frame-accurate adjustments.
  4. Fine-tune the background elements – if your video has music, sound effects, or ambient audio, adjust their volume or timing so they complement the new voice-over without overpowering it.

With careful syncing, your dubbed video will feel smooth and natural, maintaining the flow of the original while making it accessible to a wider audience.

Step 5: Export and Share Your Dubbed Video

Once your dubbed video is fully synced and polished, it’s time to export it in a high-quality format for sharing. Choosing the right export settings ensures your video looks and sounds professional, while remaining compatible with most platforms.

Recommended export settings:

  • Format: MP4 – widely supported across YouTube, TikTok, Instagram, and other platforms.
  • Codec: H.264 – offers a good balance between file size and video quality.
  • Resolution: 1080p for standard HD or 4K if your original footage supports it, preserving sharp visuals for viewers.

Additional tips:

  • Add subtitles – even if you’ve dubbed the video, subtitles improve accessibility and help viewers follow along, especially when targeting audiences in multiple languages. Many video editors or online platforms allow you to generate subtitles automatically.
  • Check audio levels – ensure the voice-over isn’t too loud or too soft compared to background music or sound effects, creating a balanced listening experience.

Finally, upload your video to your preferred platforms (YouTube, TikTok, Instagram, or others) and start reaching new audiences. A well-dubbed video can significantly expand your reach, making your content understandable and enjoyable for viewers around the world.

How to turn off dubbing on YouTube

If you prefer to watch a video in its original language, most platforms make it easy to switch off the dubbing. On YouTube and other video players, you can use the settings menu to choose your preferred audio track. The “CC” (closed captions) option often allows you to toggle between different languages or turn off the dubbed audio entirely, letting viewers hear the original speech while still having subtitles if needed. Providing this flexibility ensures that your content caters to different preferences, giving your audience full control over how they experience your video.

How do I turn on dubbing on YouTube?

To enable dubbing on a YouTube video, start by playing the video and clicking the settings icon in the bottom-right corner of the player. From there, select “Subtitles/CC” and look for the available dubbed languages. If the video offers multiple dubbed tracks, you can choose the one you want to listen to. If dubbing isn’t available, you may only see subtitles in different languages, depending on what the creator has provided. It’s important to note that not all videos include dubbed audio, so this option may not appear for every video.

Is it possible to change voices in YouTube videos?

Yes, it is possible to change the voice in a YouTube video, but not directly on YouTube itself. Once a video is uploaded, YouTube does not offer a built-in feature to swap out the audio track. To change the voice, you need to do it before uploading the video using audio or voice-changing tools. Tools like LALAL.AI Voice Changer allow you to modify or replace the original voice with a different one, whether through AI voice generation, voice cloning, or pitch and tone adjustments. After creating the new audio track, you can sync it with your video and then upload the updated version to YouTube.

Can I remove vocals from YouTube videos?

Yes! Tools like LALAL.AI make it possible to separate vocals from the rest of a YouTube video’s audio. By extracting speech or singing, you can isolate the vocals and leave just the background music and sound effects. This feature is useful if you want to create instrumental versions, remix content, or replace the original voice with a new narration or dubbed track. The process is straightforward and doesn’t require advanced audio editing skills—simply upload the video or its audio, and the AI will handle the separation.

How to convert YouTube videos to audio?
