If you want to add a voice-over in a different language to make your video accessible to a new audience, you’re essentially dubbing it. Dubbing a YouTube video can make your content accessible to a wider audience, whether you’re creating educational materials, entertainment, product reviews, clothing hauls, food recipes, or yoga tutorials. Thanks to AI-powered tools, the process is now smoother than ever—no expensive studios or complicated software required.

In this guide, we’ll walk you through the process of dubbing a YouTube video from start to finish using multiple tools and techniques.

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 technique is commonly used in film, television, and online content to make videos accessible to a wider audience.

Dubbing typically involves:

• Removing or lowering the original voice track while keeping background sounds and music intact.

• Recording a new voice-over, either by a human voice actor or using AI-generated speech.

• Synchronising the new audio with the speaker’s lip movements and the overall timing of the video.

Why Should You Dub Your YouTube Videos?

If you already use subtitles to make your content accessible to a global audience, you might wonder why dubbing is worth considering. Unlike subtitles, dubbing replaces the original voice track with a new one in another language, making the viewing experience more immersive. Here’s how it can benefit your channel:

• Reaching viewers across different countries can open up new monetization opportunities. A larger audience means more ad impressions and greater chances of attracting international sponsors.

• The more people interact with your content, the more YouTube pushes it to others. When viewers can listen in their native language, they’re more likely to like, share, comment, and subscribe.

• Offering dubbed versions of your videos shows your commitment to inclusivity and accessibility. It signals to your audience that you value their experience, which can help build trust and enhance your reputation as a creator.

3 Things to Think Through Before Dubbing a YouTube Video

Proper planning can help you avoid common pitfalls:

1. Poorly executed dubbing can make a video feel unintentionally comedic or out of sync. If that’s not the goal, every step of the process needs careful attention.

2. The new voice track should match the original speech pattern and timing. This keeps the dialogue in sync with the visuals and ensures the intended message is conveyed effectively.

3. Translate your script first. Properly translated script is essential for an accurate adaptation.

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. Creators upload their videos as usual.

2. YouTube automatically identifies the spoken language and generates dubbed versions in multiple languages. For instance, an English video will be available in French, German, Hindi, Indonesian, Italian, Japanese, Portuguese, and Spanish. Similarly, non-English videos will have an English-dubbed option.

3. Users can select their preferred language from the track menu, and YouTube will remember their choice for future videos.

4. AI-generated dubs come with a label so viewers know they’re listening to a machine-translated version.

The feature is still evolving, with Google DeepMind and Google Translate working to refine voice quality and make dubbed speech sound more natural over time.

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

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

If you don’t have your video on your device any more or if you wish to dub someone else’s YouTube video, you’ll need to start with downloading it first.

Before you can add a new voice-over, you need a high-quality version of the video or audio. If you’re working with online content, 4K Video Downloader Plus is the easiest way to grab a copy.

How to download a video or audio with 4K Video Downloader Plus:

1. Install and open 4K Video Downloader Plus.

2. Turn on the Smart Mode by toggling the bulb on.

3. Copy the URL of the video you need.

4. Click Paste Link in the app.

5. Choose 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.

6. Hit 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 version of the background sounds—music, effects, and ambient noise—without the speech. That’s where LALAL.AI comes in.

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

At this point, you can either record the new dialogue yourself or use AI-generated voices.

Option 1: Recording Your Own Voice

For a natural feel, record the new voice track manually. Use:

• Audacity (free and simple)

• Adobe Audition (for advanced editing)

• GarageBand (if you’re on a Mac)

Tips for a clear recording:

• Use a good microphone to avoid background noise.

• Match your voice tone and energy with the original.

• Speak at the same pace as the original actor for easier syncing.

Option 2: Using AI Voice Cloning or Text-to-Speech

If recording isn’t an option, AI voice generation tools like ElevenLabs, Descript, or even LALAL.AI again with its new Voice Cloner tool can create realistic voice-overs. Simply input your script or sample and generate a natural-sounding narration of your own voice!

Step 4: Sync the New Audio with the Video

Once your new voice-over is ready, sync it to the video using a video editor.

Recommended tools:

• DaVinci Resolve (free but powerful)

• Adobe Premiere Pro (professional-grade)

• Kapwing (browser-based, no software needed)

How to sync audio in a video editor:

1. Import your video and new audio file into the video-editing tool of your choice.

2. Mute the original audio track.

3. Adjust the new voice-over to match the speaker’s lip movements.

4. Fine-tune the background music and effects.

Step 5: Export and Share Your Dubbed Video

Now that your dubbed video is complete, export it in a high-quality format.

Best export settings:

• MP4 (widely compatible)

• H.264 codec (good balance of quality and file size)

• 1080p or 4K resolution (if the original video supports it)

If needed, add subtitles to improve accessibility—especially if your audience speaks multiple languages.

Finally, share your newly dubbed video on YouTube, TikTok, or any other platform where your audience is.

How to turn off dubbed on YouTube

If you prefer to watch a video in its original language, you can turn off dubbing through the settings menu. Use the "CC" (closed captions) option to switch between available languages or disable dubbing if the video provides multiple audio tracks.

How do I turn on dubbing on YouTube?

To turn on dubbing for a YouTube video, play the video and click the settings icon in the bottom-right corner of the player. Next, select "Subtitles/CC" and choose your preferred language if dubbing is available. If the video supports multiple dubbed languages, you can select the one you want to listen to. However, if no dubbing options are available, you may only see subtitles (if provided). Keep in mind that not all videos offer dubbed audio.

Is it possible to change voices in YouTube videos?

Yes, you can change the voice in YouTube videos, but not directly within YouTube Studio. Once a video is uploaded, YouTube does not provide a built-in feature to swap out the audio track. You can change the voice beforehand with voice-changing tools like LALAL.AI or HitPaw.

Can I remove vocals from YouTube videos?

Yes! With LALAL.AI, you can extract speech and vocals from a YouTube video and leave only background music and effects.

How to convert YouTube videos to audio?
