To translate a video to English with AI, upload it to a transcription tool that detects the spoken language, check the transcript, then either translate it into English subtitles or have an AI dubbing tool speak the English translation, in a stock voice or a clone of the original speaker. Subtitles take minutes and cost little; a dub takes a little longer and costs more.
This guide covers both routes, how to check the translation if you don't speak the original language, and the free options, including YouTube's automatic dubbing into English.
The short answer
Upload the video to an AI transcription tool, which detects the language and writes a timed transcript. Translate it to English for English subtitles (SRT or VTT, or burned in), or use an AI dubbing tool to speak the English translation in a stock voice or the speaker's cloned voice. Have someone who knows the source language check names and numbers.
Key takeaways
- English subtitles are the fastest, cheapest way to translate a video to English.
- An English dub suits tutorials and long videos where viewers want to listen.
- Speech recognition can stumble on less common languages; check the transcript.
- YouTube auto-dubs eligible videos into English from a long list of languages, free.
Disclosure: we make QuickVeed and show how to do this in it, along with other ways. Details about other products come from their public pages, checked in October 2026 and linked at the end.
Two ways to translate a video to English with AI
| English subtitles | English dub | |
|---|---|---|
| What viewers get | Original voice, English text | English speech, original music |
| Speed | Minutes | Minutes, plus a preparation step |
| Cost in QuickVeed | 1.5 credits a minute for the transcript, plus a credit or two for translation | Prepare 9 credits a minute (music kept), then 30 per minute in the speaker's voice or 5 with a stock voice |
| Video length in QuickVeed | Up to 3 hours | Up to 10 minutes |
| Best for | Interviews, social clips, research, archives | Tutorials, courses, product videos, YouTube |
If you just need to understand a video yourself, a transcript translated to English is enough. If you're publishing for an English-speaking audience, decide based on how they'll watch; AI dubbing vs subtitles compares them in detail.
Route 1: English subtitles
- Upload the video to an AI transcription tool. Good ones detect the spoken language automatically.
- Read the transcript. If you don't know the language, check that names, numbers and places look right.
- Translate it to English with timing kept, so each subtitle appears with its line.
- Download an SRT or VTT file to upload to YouTube or your player, or burn the English subtitles onto the video for social.
In QuickVeed's Captions & subtitles, videos up to 3 hours are transcribed with OpenAI's whisper-1, which falls back to gpt-4o-transcribe when whisper mishears a language such as Bengali. You can edit every line, translate into English (or 31 other languages) and burn captions on in 11 styles. A 20-minute interview costs 30 credits for the transcript. Free helpers: SRT to VTT converter and subtitle time shifter.
Route 2: an English dub
- Open AI dubbing and upload a video of up to 10 minutes.
- Choose Keep music and effects or Voice-over style and click Prepare for dubbing. The speech is transcribed in its original language.
- Check the transcript, fix what you can, and save it.
- Under Dub it, choose English with The speaker's own voice (cloned) or a stock voice, and click Dub.
- Download the English MP4 and the English SRT or VTT.
A 5-minute Spanish video costs 45 credits to prepare with music kept and 150 to dub into English in the speaker's voice, or 25 with a stock voice. Voice-over style, where the original is heard quietly underneath, is common for interviews and documentaries translated into English and costs 1.5 credits a minute (rounded up) to prepare. Only clone a voice you have the right to use: your own, or a speaker who has agreed to it in writing. QuickVeed requires that consent, and so should any tool you use.
Free option: YouTube's automatic dubbing into English
If the video is on your own YouTube channel and the channel is eligible, YouTube can dub it into English for free. Its help page lists source languages including Arabic, Bengali, Chinese, Dutch, Farsi, French, German, Hebrew, Hindi, Indonesian, Italian, Japanese, Korean, Malayalam, Polish, Portuguese, Punjabi, Romanian, Russian, Spanish, Swahili, Tamil, Telugu, Thai, Turkish, Ukrainian, Urdu and Vietnamese. Videos over 120 minutes, with little speech, or with speech that's too fast are not eligible.
The trade-offs: you can't edit the dub (only correct the video's original language to regenerate it), and it plays only on YouTube. For a dub you can fix, use elsewhere or speak in your own voice, use a dubbing tool. YouTube viewers can also auto-translate captions into English themselves, which is free but out of your control.
Prepare the video for a better translation
AI translation can only be as good as the transcript under it, and the transcript depends on the audio. Before you upload:
- Use the best audio you have. The original recording beats a re-downloaded copy from a social platform.
- Cut long silent or music-only parts that add minutes without speech. Our free video speed changer and other free tools run in your browser.
- Note the names. Write down people, places, brands and technical terms you expect to hear, so you can fix them in the transcript.
- Know the language. If the video mixes two languages, expect to correct some lines by hand.
- Split very long videos for dubbing: QuickVeed dubs up to 10 minutes per video, while captions handle up to 3 hours.
Short test first: translate the first two minutes, check them, and only then run the whole video. It costs little and shows you early whether the audio is good enough. Cut the clip in any editor, or use a short excerpt you already have.
If you plan to publish the English version, also check that you have the rights to translate and republish the video. Translating someone else's video doesn't make it yours; get the owner's permission first, especially before cloning the speaker's voice.
If the transcript comes back in the wrong script or language, that's usually a sign of poor audio or a less common language; a careful check of the first minute tells you whether the rest is usable.
How to check a translation when you don't speak the language
- Check the proper nouns. Names, brands, places and numbers should match what's on screen or in your notes.
- Back-translate a sample. Paste a few original lines into a different translation tool and compare the English.
- Watch with subtitles on. Lines that don't match the speaker's gestures or the scene are usually wrong.
- Ask a native speaker to watch the parts that matter most: claims, prices, legal or medical points.
- Watch for mixed languages. Speakers who switch between their language and English can confuse transcription; fix those lines by hand.
For multi-speaker videos, note that QuickVeed's dubbing clones one voice from the speech, so a stock voice works better when several people talk. For more languages beyond English, see how to dub a video into another language.

How do I get English subtitles for a foreign-language video?
Upload it to an AI captions tool, let it transcribe and translate to English, then download the SRT or VTT file or burn the subtitles onto the video.
Can I translate a video to English in the original speaker's voice?
Yes, with voice-cloning dubbing. QuickVeed does it for 30 credits a minute. Only clone a voice with the speaker's consent.
