YouTube video translator English subtitles, no CC needed
Talks, interviews and vlogs in a language you don't speak — and the CC button is grey. WatchTranslate puts English right on the YouTube player, with the original line underneath.

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.

- Half the jokes and asides slip past
- Some videos have no caption track, so no auto-translate
- Auto-captions show one language at a time

- English appears as each sentence is spoken
- Names and terms can be checked against the Spanish line
- A full lecture can be prepared before you press play
English subtitles on a YouTube video in three steps
Install the extension
Add WatchTranslate to Chrome or Edge on your computer. It takes half a minute.

Open the video on YouTube
Play it as usual — no YouTube account needed. Let any ad finish first.
WTNow we have a parallel digitalClick 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.
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.
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.

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.
| The video you're watching | What the YouTube player offers | With WatchTranslate |
|---|---|---|
| Creator uploaded English captions | Pick English in the captions menu | Just use YouTube's captions |
| Only foreign or auto-generated captions | Auto-translate works, one language at a time; auto-captions often break mid-sentence | English and the original together; re-listen when the captions are messy |
| New upload with no caption track | The CC button is grey, so there is no auto-translate | Transcribes the audio and translates as it plays |
| Lectures and replays of an hour or more | Same as above, video by video | Prepare the whole video's subtitles in advance |

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.
What YouTube itself says
From the YouTube Help Center, checked signed out of YouTube on .
Automatic captions are generated by YouTube's speech recognition, and not every video has them.

Getting the best results
Start with one main speaker
Talks, interviews and vlogs where one person speaks at a time give the cleanest lines.
Loud music? Keep the original line
When music or crosstalk gets loud, the original line helps you check what was said.
Keep a transcript
Export SRT or VTT after a lecture so you can search it later.
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.
