Yes. YouTube automatically generates subtitles for videos you upload, long-form videos and Shorts alike, as long as the speech is in one of the languages its speech recognition supports. You do not need to switch anything on. As of 21 October 2026, YouTube's help page lists 67 languages for these automatic captions, and English only for live streams.
Three conditions apply. The captions follow the video's language setting, so a wrong setting gives you the wrong language. They are not instant; YouTube says they "may not be ready at the time that you upload a video." And they are a draft: YouTube itself tells creators to "always review automatic captions" and fix what was not transcribed properly. This guide covers each of those, plus how viewers translate them.
What YouTube says about automatic captions
YouTube's help page on automatic captioning, read on 21 October 2026, makes four points worth knowing:
- "YouTube can use speech recognition technology to automatically create captions for your videos."
- The captions "are generated by machine learning algorithms, so the quality of the captions may vary."
- "If automatic captions are available, they'll automatically be published on the video." There is no approval step unless you go in and edit.
- "We encourage creators to add professional captions first." YouTube treats auto captions as a fallback, not a replacement.
Viewers see automatic captions as a track they switch on with the CC button; the words are not part of the picture. Other tools that auto generate subtitles, from Premiere Pro to CapCut and Instagram, are covered step by step in how to auto generate subtitles.
Which languages does YouTube auto caption?
For long-form videos and Shorts, YouTube's list on 21 October 2026 has 67 languages: Afrikaans, Albanian, Amharic, Arabic, Armenian, Azerbaijani, Basque, Belarusian, Bengali, Bulgarian, Burmese, Cantonese/Hong Kong, Central Khmer, Chinese, Czech, Danish, Dutch, English, Estonian, Farsi, Filipino, Finnish, French, Galician, Georgian, German, Greek, Gujarati, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Italian, Japanese, Javanese, Kannada, Korean, Lao, Latvian, Lithuanian, Macedonian, Malay, Malayalam, Marathi, Mongolian, Nepali, Norwegian, Polish, Portuguese, Punjabi, Romanian, Russian, Sinhalese, Slovak, Spanish, Sundanese, Swahili, Swedish, Tamil, Telugu, Thai, Turkish, Ukrainian, Uzbek, Vietnamese and Zulu.
A few details from the same page:
- Live streams: automatic captions are English only, and YouTube says they are rolling out to channels with more than 1,000 subscribers on normal-latency streams.
- English extras: English automatic captions support what YouTube calls expressive captions, showing loud speech in capitals and sounds like sighs, gasps and background noise.
- Not on the list: Urdu does not appear. Neither does any mixed language such as Hinglish, so a video that switches between Hindi and English mid-sentence gets captions in one language or the other.
Why YouTube auto captions are in the wrong language
YouTube does not caption each sentence in whatever language it hears. Its "Add subtitles & captions" page says: "Automatic captions will be in the video's default language only." If the video language was never set, or was set wrong, the captions come out as one language's guess at another's speech. And if a video has several audio tracks, the automatic captions use the default track's language.
To set or fix the video language, per YouTube's help page on 21 October 2026:
- Sign in to YouTube Studio and select Content from the left menu.
- Click the video's title or thumbnail.
- Scroll down and click SHOW MORE.
- Under Language and captions certification, choose the language spoken in the video.
- Click SAVE at the top of the page.
Only the uploader can change this. YouTube's page says the change affects future translated subtitles and that "your published and draft subtitles and closed captions won't be affected." It does not say whether YouTube then makes a new automatic track in the corrected language. If none appears after a while, add a track yourself: in Studio, go to Subtitles, click ADD LANGUAGE, then ADD, and use Auto-sync with a transcript (YouTube requires it to be in the spoken language and in one its speech recognition supports) or Upload file if you have a caption file.
How to review, edit and publish auto captions in YouTube Studio
Because auto captions publish themselves, the review happens after upload. YouTube's steps for a computer:
- Sign in to YouTube Studio and select Subtitles from the left menu.
- Click the video.
- In the Subtitles column, select Edit for the language.
- For automatic captions, choose Duplicate and edit, then Continue.
- Click into any line and correct the text. To change when a line appears, use the two timestamp boxes beside it (select Edit timings if you do not see them).
- Click Publish.
YouTube notes that editing automatic captions creates "a new caption track that includes your revisions", so your edited version sits alongside the original rather than overwriting it. To remove a track entirely, use Options, then Delete.
Check names, numbers and anything said over music first. If the track shows "[ __ ]" in place of a word, that is YouTube's "Don't show potentially inappropriate words" setting, which is on by default, not a recognition error. Words such as "foreign" or "thank you" over silence are a different issue, explained in why YouTube captions say "foreign" or "thank you".
Can you edit auto captions on mobile?
YouTube's help pages describe caption review and editing only in YouTube Studio on a computer. On 21 October 2026, the Android and iPhone versions of the "Edit or remove captions", "Add subtitles & captions" and "Use automatic captioning" pages all give the same desktop steps and no separate Studio app instructions. If the Studio app on your phone does not show a subtitles editor for the video, do the review on a computer.
How viewers turn on and translate auto captions
Viewers control auto captions from the player, not from your channel.
- On or off: click or tap the Closed captions (CC) button. If there is no CC button, there are no captions for that video yet.
- Auto-translate: YouTube's "Manage caption settings" page says that if the language you want is not listed when you open Subtitles/CC, click Auto-translate and pick a language. Auto-translate starts from a caption track the video already has, so mistakes in your auto captions carry into every translation. Fixing them first helps viewers in every language.
- Show when muted: on phones and tablets, a Show when muted setting in the captions menu turns captions on whenever the sound is off.
When YouTube auto captions don't appear
YouTube lists six reasons a video may get no automatic captions: the audio is complex and still processing, the language is not supported, the video is too long, the sound is poor or the speech is not recognized, there is a long silence at the start, or speakers overlap or mix languages. YouTube gives no processing time in minutes, only that it "depends on the complexity of the video's audio."
Each of these, and what to do about it, is covered in YouTube auto captions missing or late.
Should you rely on auto captions?
For a normal upload, keep them and review them. They cost nothing, help deaf and hard-of-hearing viewers, and give viewers something to auto-translate. Replace them with your own track when the language is not supported, the speech is mixed, or accuracy matters; YouTube itself encourages professional captions first.
Shorts are different. Auto captions on a Short are a track the viewer has to switch on, so someone watching on mute with captions off sees no words at all. Many Shorts creators burn captions into the video instead, so the words are part of the picture. The trade-offs between YouTube's track and burned-in captions are laid out in YouTube auto captions vs burned-in subtitles.
If you go the burned-in route for Shorts, the YouTube Shorts caption generator captions an MP4 or MOV up to 10 minutes long in 11 spoken languages (English, Hinglish, Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada and Punjabi), lets you fix every word and timing, and exports an MP4 with the captions burned in. It does not take a YouTube link, upload a caption track to YouTube, export subtitle files or translate. There are 3 free minutes to start, packs are paid once from $4 (₹49 in India, €4 in the euro area), and watermark-free export comes with every paid pack.
What to do next
Check the video language in Studio before or right after upload, give the automatic track time to appear, then review it with Duplicate and edit. If you need the caption text as a file afterwards, see how to download subtitles from YouTube.
