How to Dub a Video into Portuguese with AI (2026 Guide)

If you are a creator or a business looking to expand your reach internationally, ignoring the Brazilian market is a massive missed opportunity. Brazil routinely ranks in the top three countries globally for YouTube and TikTok consumption.

However, there is a catch: only about 5% of Brazilians speak English fluently. If you want to reach this audience, subtitles aren’t enough—you need to speak their language.

In the past, dubbing a video into Portuguese meant hiring a voice actor, paying a translator, and spending hours in a studio. In 2026, AI has reduced that process to a single click.

Here is exactly how to dub your videos into Portuguese using AI.

Step 1: Upload Your Video to an AI Dubbing Platform

To get started, you need an AI platform capable of handling complex translation and voice synthesis. While there are several tools on the market, we recommend Braiv because it offers native voice cloning and multi-speaker detection out of the box.

1. Create a free account at Braiv.co.
2. Click “New Project” and upload your MP4 file, or simply paste your YouTube link directly into the dashboard.

Step 2: Select “Portuguese (Brazil)” as the Target Language

Once your video is processed, Braiv will automatically transcribe the original audio.

1. Navigate to the Dubbing tab.
2. Select Portuguese (Brazil) from the dropdown menu. (Note: Braiv also supports Portuguese (Portugal), but the Brazilian dialect is essential if you are targeting the South American market).

Step 3: Enable AI Voice Cloning

This is where the magic happens. Instead of using a generic, robotic text-to-speech voice, you want the Portuguese dub to sound exactly like you.

• Check the box for “Clone Original Speaker Voices”.
• Braiv’s AI will analyze the vocal characteristics, tone, and pacing of the speakers in your video. It will then generate a synthetic Portuguese voice that perfectly matches the original speaker’s identity.
• If you have a podcast with two different hosts, the AI will automatically assign a unique cloned voice to each host.

Step 4: Review the Translated Transcript

AI translation is incredibly advanced, but it’s always a good idea to review the text before rendering the final audio, especially for brand names or industry-specific jargon.

• Open the Transcript Editor. You will see the original English text side-by-side with the Portuguese translation.
• If you need to make a tweak (for example, ensuring a specific technical term isn’t literally translated), simply edit the text. The AI will instantly regenerate the audio to match your changes.

Step 5: Export and Publish

Once you are happy with the preview, click Render. In just a few minutes, Braiv will generate your new Portuguese video file.

You now have a fully localized asset ready to be uploaded to a dedicated Brazilian YouTube channel or shared on TikTok.

Pro Tip: If you want to save even more time, you can use the Braiv Player to embed the video on your website. The player allows users to dynamically switch between the English and Portuguese audio tracks on the fly, just like Netflix!
