Part 1. The "Speech-to-Text-to-Speech" Workflow Explained

The technology behind YouTube video audio translation usually comes down to two core tools: Speech to Textand Text to Speech. These two work together to turn your original audio into a new voice in another language without a human voice actor. It can also generate subtitles that you can pair with the new audio track.

The process can be broken down as follows:

1. Speech to Text (STT): Using the audio in your video, the tool will convert your spoken words into text. The output becomes your original script or caption.
2. Translation: The script is then translated into the language you want. A new version of the script or caption is ready for dubbing.
3. Text to Speech (TTS): The translated script is turned into a new AI voice. Depending on the tools, you can choose from several voice options to find the one that fits your video's style the best.

During the process, other technologies may also come into play, such as AI lip sync. It's an optional feature that helps you adjust mouth movements to match the new voice so everything looks natural and in sync.

Part 2. How to Translate YouTube Audio Using Built-in Auto-translate

Before we move into a more advanced YouTube voice translator, YouTube actually has its own auto-translate feature, both for the audio and captions. It's not perfect, but it's the quickest way to translate or dub a video in another language without using extra apps.

Best for: Creators who need a quick way to offer translations without doing any editing.

When you've published everything, your viewers can access it through the YouTube settings menu. From there, they can switch to the translated subtitles or audio track in the language they prefer.

Pros & Cons of Using YouTube's Auto-translate

• Built directly into YouTube
• Convenient for your viewers since they can instantly switch languages from the settings menu
• Works automatically once captions are published

• Accuracy may not be the greatest; it depends heavily on auto-generated captions
• No option to choose or customize AI voices
• Currently available only for selected languages and regions
• Doesn't offer lip-sync or extra editing tools

How to Enable Auto-Translate on YouTube

Step 1: Open YouTube Studio and Choose Your Video

Sign in to YouTube Studio and head to the Subtitles section. Pick the video you want to translate from your content list.

Step 2: Prepare and Publish Your Original Captions

Before you can translate audio from YouTube video, you need to publish the auto-generated captions for your main language.

1. Look for the row labeled automatic captions, then select Duplicate and Edit.
2. On the subtitle editor, click Publish.

Step 3: Translate the Subtitles to Another Language

Once your primary captions are published, you can start generating subtitles in other languages.

1. Go back to the Subtitles section.
2. Select Add Language, then choose the language you want to add.
3. Click Add under the subtitles column for that language.
4. In the new window, choose Auto Translate.

YouTube will automatically create translated subtitles for you. Feel free to adjust any lines if needed, then hit Publish to save your new subtitle track.

How to Enable Auto Dub on YouTube

YouTube's built-in translator uses the original captions as the base, so if the video doesn't have subtitles, the feature may not show up.

Step 1: Open YouTube Studio Settings

Open YouTube Studio and go to Settings.

Step 2: Enable Automatic Dubbing

Select "Upload defaults" > "Advanced settings." Then, look for the Automatic Dubbing option and click Enable.

After that, you'll be able to adjust a few extra settings:

• Make sure you've checked the automatic dubbing option.
• Decide whether you want to review the dubbed audio before posting and which languages you want to review (all available languages or only the experimental ones).

Click "Save" to apply the changes.

Step 3: Remove or Unpublish the Dubbed Audio

If you want to remove or unpublish the dubbed audio:

1. Head to the Languages section in YouTube Studio.
2. Select the audio track you want to change.
3. Choose whether you want to remove it completely or unpublish the dub audio.

Part 3. How to Translate YouTube Video Audio into Text or Audio (Lipsync)

Since YouTube's auto-translate feature has limits in accuracy and customization, you might want a more flexible way to translate YouTube video audio. In that case, it's better to use a video voice translator software like Wondershare Filmora.

Filmora features an AI Translation tool, which can help you:

• Translate your video's audio into text.
• Generate a new dubbed voice.
• Lip-sync the translated audio so it matches the speaker on screen.

Everything happens in one workflow, so you don't need to jump between different settings or apps. And since the tool is built into the software, you can do more than just translate. You can also use Filmora to edit and refine your video.

Pros & Cons of Using Filmora

• Includes a lip-sync feature that aligns mouth movements with the translated audio
• Complete Speech-to-Text, Translation, and Text-to-Speech workflow in one place
• You can switch AI voices or use AI Voice Cloning for a more personalized result
• Built-in editing tools that let you refine timing, captions, and audio
• Supports exporting both the translated video in many popular formats and subtitle files

• Requires desktop installation, so it's not fully browser-based
• Lip-sync accuracy depends on the quality of the original footage

Best for: Creators who want high-quality multilingual videos with accurate timing, customizable voices, and a full editing workflow in one software.

How to Translate YouTube Video Audio with Filmora

Make sure you've installed or updated Filmora to the latest version to get the latest features and the most optimized performance. Then, follow the steps below.

Step 1: Start a New Project and Import Your Video

Open Filmora, create a new project, and bring in the video you want to translate.

Step 2: Access the AI Translation Tool

Right-click on your video in the Media panel or timeline, then choose AI Translation to open the tool.

Step 3: Adjust the Translation Settings

Now that the AI Translation panel opens, set up the parameters:

• Choose whether you want to translate both the voice and captions, or captions only
• Set your source language and your target language
• Turn on Lip Sync if you want the mouth movements to match the new audio

When everything looks right, click Translate to start the process.

Step 4: Review the Results and Add Them to the Timeline

When the translation is complete, the newly generated media will appear in the Media panel. Drag the translated video (with lip sync, if enabled) to your timeline along with the translated captions.

To customize the caption, double-click the subtitle track in the timeline. This will open the subtitle editing window, where you can adjust the text and styling.

Step 5: Export the Video or Subtitle File

After everything looks good, you can export your final video or save just the subtitle file. If you're exporting the video, head to the Export button, choose your format, and finish the process.

If you only need the subtitles, right-click the caption track and select "Export Subtitle File" > "Export Subtitle File (.srt)."

Tip 1: Change the AI Voice

If you play the result, Filmora will try to match the tone of the original speaker. But you can switch to a different AI voice if you wish. You can even use AI Modeling (AI Voice Cloning) to generate the translated audio in your own voice if the result doesn't feel right.

To change the voice:

1. Select the caption track on the timeline.
2. Open the Text to Speech section in the Properties panel.
3. Choose the voice you want and click Generate.

After a moment, Filmora will create a new voice track that you can drag onto your timeline and replace the original translated audio.

Tip 2: Add Original Caption

Since AI Translation only creates translated captions, you can still generate the original captions in Filmora.

1. Add the original video to your timeline.
2. Select Speech to Text under the Titles > AI Captions panel.
3. Adjust the settings and choose No Translation, since you only need the original language.
4. Click Generate to create the captions.

Filmora will then produce the subtitles in the original language. You can also export the captions as an SRT file if you want to upload them to YouTube Studio or use them on other platforms.

The next practical way to translate your YouTube audio is by using a YouTube video voice-to-text converter online, such as Maestra. This tool can automatically convert your video's spoken audio into text, translate it, and even create an AI-dubbed version right in your browser.

Maestra supports translation in more than 125 languages, whether you prefer subtitles or full AI dubbing. It also includes lip-sync support, so the translated audio lines up more naturally with the speaker's mouth movements.
