How to Translate YouTube Videos by YouTube Auto-Translate Feature

If you want to translate YouTube videos to your language for watching, one of the easiest solutions is using YouTube’s native auto-translate feature.

So long as the original YouTube creator indicates the language in which the video has been made, you can use YouTube’s auto-translate feature to auto-translate YouTube videos into as many as 125 languages. Here is how to auto-translate YouTube videos:

How to auto-translate YouTube videos using YouTube’s native auto-translate feature.

Step 1
Find the YouTube video you want to translate > click the CC icon to activate the auto-translate feature on YouTube.
Step 2
Click the settings icon, which looks like a gear > Subtitle/CC > select Auto-translate option > select your language from 125 languages available to auto-translate the YouTube video.

The only downside with YouTube's auto-translate feature is that due to the diverse accents and languages, the auto-translation is not that accurate.

Another tricky thing is that if the YouTube video creator forgets to specify which language the video is made in, by default Youtube will take the language as English and if the video is not spoken in English, Youtube can’t auto-translate YouTube videos.

Translate YouTube Video to English without CC

Well, if the YouTube video you are watching does not have the CC icon (or closed caption option) available, then you have no way to use the auto-translate feature on YouTube.

In this case, another flexible way to translate YouTube video to English without CC is to use Sonix.AI, a user-friendly audio and video transcription service online. With Sonix, you can paste the URL of a YouTube video and let AI transcribe the YouTube video to text and translate the YouTube transcript to your language in one place.

So, let’s find out how to translate YouTube video from Spanish to English:

Step 1
Import the YouTube video’s URL and transcribe YouTube to text.

Visit Sonix.AI’s website > sign up for free for Sonix > click the Upload button > click the YouTube icon and paste your YouTube video’s URL > click Transcribe YouTube video > identify the source language, in this case is Spanish > hit Transcribe in Spanish.

Step 2
Translate YouTube videos to English.

Click the Translations tab > select Translate Transcript to a Different Language > select English > hit the Translate Now button. After the translation is done, you can playback the YouTube video with English subtitles or click the little global icon to compare the original language and the translated language.

Step 3
Click the Export button to download the translated YouTube video in TXT, DOCX, PDF, or SRT file.

The only drawback of using Sonix.AI to translate YouTube videos without CC is that you can’t burn the translated subtitles into the YouTube video and save it as an MP4 video.

    Translate YouTube Videos with Lip-syncing

    Last, but not least, if you want to take a step further by not only translating YouTube videos but also syncing speaker’s lips to the new language using AI, another ultimate solution is using HeyGen, another rising AI video creator online.

    How to translate YouTube videos with lip-syncing by HeyGen.

    Currently, HeyGen can translate YouTube videos from 18 source languages to 29 target languages. Make sure your YouTube video is in MP4, MOV, or WEBM format and doesn’t exceed 1GB.

    Step 1
    Visit HeyGen’s video translate page > drag to upload your YouTube video to HeyGen.
    Step 2
    Click the drop-down menu of Target Language> select from 29 languages for your target language > hit the Translate This Video button.
    Step 3

    While HeyGen seems to be a game-changer for translating YouTube videos with lip-syncing, it has some limitations. For example, you can't paste YouTube URLs for translation, and it may encounter errors when handling YouTube videos with background music or multiple speakers. Plus, the 5-minute maximum video translation only works for bite-sized YouTube videos.
