How to Translate Voices in YouTube Videos: Using AI Dubbing for a More Immersive Viewing Experience

YouTube's automatic captions and automatic translations are indeed very convenient. They are usually enough for temporarily understanding a video. But if you want to show a non-native course, product demonstration, or popular science content to students or clients, or want to hear a favorite speaker or character speak in a language you are familiar with, just reading the translated captions will not be enough.

I've been feeling this more and more recently: Video Translation不只是把字幕翻成另一种语言。很多时候，我们真正想要的是翻译视频中的人声，让原本需要盯着字幕看的内容，变成可以沉浸观看、甚至只用耳朵听的内容。)

Why I started trying to translate the voices in videos

Nowadays, Agent tools and large language models are becoming increasingly powerful. Giving your own Agent tool, such as Codex or Claude Code, a YouTube video link to help you handle downloading and organizing materials is no longer very complicated. Next, open Souldub，上传视频，选择目标语言，比如泰文到英文，或者英文到西班牙文，就可以创建视频翻译任务，等待任务完成，就可以下载翻译好的视频到你的电脑上了。

The first time I used this method was to translate a speech video that I really liked. After completing the task, what I received was not just translated subtitles, but a version of the video in the target language: the voice was changed to a language I was familiar with, while trying to preserve the original speaker's tone, intonation, and emotional expression as much as possible.

The experience this brings is very different. Before, I had to keep staring at the subtitles, and if I got slightly distracted, I would miss content. Now I can listen directly during lunch breaks, commuting, or when it's inconvenient to look at the screen. For some classic speeches, interviews, or podcast-type videos, watching them once always feels insufficient, and being able to listen repeatedly in a familiar language is itself a new way of using them.

The process of translating YouTube videos with Souldub

If you also want to translate YouTube videos, I suggest starting with videos that you have the rights to handle and publish. The full process is not complicated; the core principle is: let AI complete the repetitive work first, and then have humans check the key points.

Step one, upload the video to Souldub.

Step two, select the source language and the target language. For example, you can translate a Chinese video into English, or you can create different language versions of the same video in Spanish, Thai, and so on.

Step three, generate translated subtitles and AI voice-over in the target language. As an AI video translation tool, Souldub will recognize the speech content in the video and generate editable subtitle text.

Step four, enter the dubbing editing page and manually adjust the subtitles and audio. No matter how powerful AI is, there may still be certain parts that don't fully match your ideas, so it's necessary to check before exporting.

What other videos are suitable for voice translation?

The first thing that comes to mind is speech videos. A good speech involves not only the content, but also the speaker's pauses, intonation, and emotions. If you only look at the subtitles, you will indeed miss a layer of experience.

Science popularization and educational videos are also very suitable. For example, if children or students have not yet mastered the original video's language, but the content itself is very valuable, using YouTube video translation to convert both subtitles and voice into a language they are familiar with is more intuitive than just providing a line of subtitles.

For creators, this process also has practical value. The same product introduction, tutorial, or knowledge-based video can be turned into multiple language versions through video translation, for distribution in different markets. If there is a need to batch process the content library later, you can also check out Video Translation API or Souldub Skill.

Of course, there may be many other types of videos that can be translated, waiting for everyone to imagine and try for themselves.

Why manual calibration is still important

I do not recommend publishing AI-generated results without looking at them at all. Especially the following areas, it is best to spend a few minutes checking:

• Names of people, brand names, course names, and professional terms;

• Does the translated sentence sound like something a native speaker of the target language would say?

• Are the subtitles too long for the audience to read in time;

• Whether the dubbing basically matches the rhythm of the visuals;

• Do individual segments need to have their voiceovers regenerated?

This is also why I believe being able to edit is more important than just one-click generation. A good video translation tool should not just give you a result, but should allow you to correct areas that obviously affect the viewing experience before exporting. The first time you use it, you can first take a look at the video audio translation user documentation，用一条短的视频跑完整流程。)

Frequently Asked Questions

Can YouTube videos be translated into English?

Sure. You can upload the video to Souldub, choose English as the target language, and generate English subtitles and English AI dubbing. Besides English, you can also translate English videos into Spanish voice. Currently, translations between voices in 30 different languages and dialects are supported.

When translating YouTube videos, can subtitles and AI voice-over be generated at the same time?

Sure. The process of Souldub is not just about generating subtitles; it also handles speech recognition, subtitle translation, and AI dubbing in the target language, making it suitable for videos that need to be released in the target language version.

Can the AI-generated dubbing be manually adjusted afterwards?

Sure. You can check each subtitle and dubbing, make corrections to unnatural translations, and also regenerate dubbing for segments that need adjustments.

Isn't it fine to just watch YouTube's automatic captions?

If you only need to understand the content temporarily for yourself, YouTube's automatic captions are of course sufficient. But if you want to show the video to an audience that doesn't understand the original language, or if you want a more natural auditory experience, combining subtitle translation with AI dubbing will be more complete.

Ending

Video sound translation has brought me a new way of watching. It not only turns the content into another language, but also transforms videos that originally required staring at subtitles into content that can be watched more naturally and listened to repeatedly.

If you also have a YouTube video you want to translate, you can start by trying with a short video of 1-3 minutes: upload the video, choose the target language, translate, adjust the subtitles and dubbing, and then export the final translated video.
