Every video you have already made can find a second audience in another language. Localization used to mean translators, voice actors and a recording studio for each market. With AI, a small team can produce a translated voiceover and subtitles for a video in an afternoon - and spend the saved budget on a native speaker's review.
Subtitles, voiceover or both?
| Option | Effort | Best for |
|---|---|---|
| Translated subtitles | Lowest | Talking-head videos, interviews, content where the original voice matters |
| AI voiceover in the new language | Medium | Explainers, tutorials, product videos, ads and faceless content |
| Voiceover + subtitles | Medium | Maximum accessibility and watch time |
Step 1: Transcribe the original
Upload your video to Transcribe and download the transcript with timestamps. Correct names, brand terms and anything the speaker mumbled before you translate - errors here get multiplied in every language. If your source is not in English and you need an English version, choose Translate to get English text directly. Our transcription guide covers the details.
Step 2: Translate and adapt the script
Translate the corrected transcript with your preferred translation tool or a writing assistant, then adapt it rather than translating word for word:
- Keep the timing in mind. Many languages need more words than English for the same idea. Shorten sentences so the voiceover still fits the scenes.
- Localize examples. Currencies, units, dates and cultural references should make sense to the new audience.
- Keep a glossary. Decide once how product names and key terms are translated - or whether they stay in English.
Have a native speaker review it. Machine translation is fast but can be confidently wrong. A ten-minute review by a fluent speaker is the cheapest quality insurance you can buy.
Step 3: Generate the voiceover
Paste the translated script into Text to Speech, set the language explicitly and choose a voice that fits your brand. Pynokio supports 30 languages, including Spanish, Portuguese, French, German, Italian, Polish, Turkish, Arabic, Hindi, Indonesian, Japanese, Korean and Chinese.
- Generate scene by scene using the timestamps from Step 1, so each section lines up with its picture.
- Use Speed to fit the timing. A slightly faster setting helps a longer translation fit a fixed scene; avoid extremes that sound rushed.
- Keep the same voice in every language if you want a consistent brand sound - for example your own cloned voice, used with your consent.
Step 4: Create subtitles in the new language
Run the new voiceover through Transcribe to get perfectly timed subtitles in the target language, then export SRT for YouTube and most editors or VTT for web players. Proofread once more - subtitles are read word by word, so small errors are noticed.
Step 5: Assemble and publish
- Replace (or duck) the original voice track with the new voiceover in your editor.
- Keep the original music and sound effects - or create new ones in Music and Sound Effects if the original mix is not available as separate tracks.
- Add the subtitle file and translate the title, description and thumbnail text.
- Publish as a separate video, or upload the new audio as an additional audio track where your platform supports it.
Be transparent with your audience
Tell viewers that the voiceover is AI-generated, for example in the description. If you are recreating a real person's voice in another language - a presenter, a founder, a guest - you need their permission first. Every voice generated in Pynokio carries an inaudible watermark and a provenance record; see voice cloning, consent and the law.
Key takeaways
- Fix the source transcript first - errors multiply across languages.
- Adapt, do not just translate, and keep sentences short enough for the timing.
- Generate the voiceover scene by scene and subtitles from the new audio.
- Get a native speaker review and disclose AI voices.
FAQ
Can AI dub a video into another language?
Yes. Transcribe the original, translate the script, then generate a new voiceover in the target language with Text to Speech and replace the original voice track.
Which languages are supported for the voiceover?
Pynokio Text to Speech supports 30 languages.
Can the translated version use the original presenter's voice?
Only with the presenter's written permission. With consent, you can create a voice clone and use it for the translated voiceover.
Can Pynokio translate the speech for me?
Transcribe can translate speech from other languages into English text. For other target languages, translate the transcript with a translation tool and have it reviewed by a native speaker.
