Auto-translate needs captions first

YouTube can only auto-translate a caption track that already exists. Many talks, interviews and vlogs have none, or only messy auto-captions in the original language.

Add to Chrome
Step 1

Step 2

Open the video on YouTube

Play it as usual — no YouTube account needed. Let any ad finish first.

Step 3

Click WT on the player

Click WT in the player controls and set Target language to English. With no captions, set Subtitle source to Audio recognition, then switch it on. Subtitles start with the next line spoken.

What it does

Built for foreign-language videos on YouTube

No captions? It listens

Set Subtitle source to Audio recognition: it transcribes the speech, then translates it into English.

Has a caption track? It uses it

Creator captions or YouTube's auto-generated ones are translated directly, keeping their timing.

English on top, original below

Both lines on screen, so names and phrases you half-recognise line up with the translation.

Now we have a parallel digital world where we can take refuge, and that is very dangerous,Ahora tenemos un mundo digital paralelo donde refugiarnos, y eso es muy peligroso,

Messy auto-captions? Listen again

When YouTube's auto-captions break mid-sentence, switch to audio recognition for cleaner lines.

Prepare a long lecture first

Click Translate all subtitles in advance and keep watching while the whole video is prepared.

Keep the subtitles

Export SRT or VTT from the Export tab for notes, study or another player.

Compared with YouTube's own captions

Are YouTube's own captions enough?

Often, yes. If the creator uploaded English captions, or auto-translate offers English, use that. WatchTranslate is for the cases below.

How it works

How it works

What happens when I skip ahead?

WatchTranslate works through the video in 30-second segments: the one playing and the next one. Jump to another minute and it starts with the segment at that point.

How does it keep names and terms consistent?

Each line is translated with its neighbours in view, so a name or term reads the same way through the video. Translation and original share one timeline, which keeps the two lines together.

Why do some videos show subtitles straight away?

If someone has already translated the same video into the same language, WatchTranslate reuses that result and shows it right away.

Best results

Getting the best results

  1. Start with one main speaker

    Talks, interviews and vlogs where one person speaks at a time give the cleanest lines.

  2. Loud music? Keep the original line

    When music or crosstalk gets loud, the original line helps you check what was said.

  3. Keep a transcript

    Export SRT or VTT after a lecture so you can search it later.

FAQ

YouTube video translator questions

How do I translate a YouTube video into English?

Install WatchTranslate in Chrome or Edge, open the video on YouTube, click WT in the player controls, set Target language to English and switch it on. It translates the caption track if there is one; with Subtitle source on Audio recognition, it listens to the speech.

Can I translate a YouTube video that has no subtitles?

Yes. Set Subtitle source to Audio recognition. It transcribes the speech, translates it, and picks up again after you pause or skip.

How is this different from YouTube's auto-translate?

YouTube's auto-translate only works on an existing caption track and shows one language. WatchTranslate also works with no captions at all and shows English and the original together.

Do I need to sign in to YouTube?

No. We tested signed out of YouTube. You do need a free WatchTranslate account, which holds your free minutes.

Does it work for Japanese or Spanish videos?

Yes. Leave Source language on Auto-detect or pick it yourself, then set Target language to English.

Can I get the whole video translated before I start?

Yes. Click Translate all subtitles in advance in the panel and keep watching while it works through the rest.

Is there a YouTube translator for my phone?

On Android or iPhone, install the WatchTranslate app, open the YouTube video inside the app and tap Translate.

Can I download the translated subtitles?

Yes. Export SRT or VTT from the Export tab.

How much is free?

New accounts get 20 free minutes, no card needed.

Is WatchTranslate made by YouTube?

No. It is an independent extension and app that shows subtitles over the YouTube player without changing the video.
