How to translate anime in real time while watching Crunchyroll

By the end of this guide, you’ll have live captions and up to two translations showing over Crunchyroll on your Windows PC. OMNI listens to the episode and turns the speech into translated captions. Everything runs on your PC, so the audio, captions, and translations aren’t uploaded to a cloud service.

Key takeaways

• OMNI listens to Japanese audio playing on your PC.
• The app turns speech into live captions.
• OMNI’s built-in AI translation translates complete sentences on your PC.
• Two target languages can appear beside each other.
• The caption window works without browser extensions or OBS, a free program used for streaming and recording.
• There are no monthly fees or per-minute translation charges.

What you need

You need a Windows PC and a little time for the first downloads:

• A 64-bit Windows 10 or Windows 11 PC.
• A modern NVIDIA graphics card for the best real-time performance.
• OMNI Live Translator, which includes a full 30-day trial with no credit card.
• A Crunchyroll account and lawful access to the episode you want to watch.
• The Crunchyroll website or Windows app playing on the same PC as OMNI.
• Headphones or speakers connected to the sound output OMNI will listen to.
• Enough storage for the language files you choose.

After the first setup, the downloaded languages work without an internet connection. You don’t need an OMNI account to use them.

How to translate anime in real time on Crunchyroll

The easiest setup uses Crunchyroll’s Japanese audio and OMNI’s movable caption window. You can keep this window above the video while you watch.

1. Check whether Crunchyroll already provides your language.

   Open the anime’s page, select More Details, and check the listed Audio and Subtitles languages. Crunchyroll warns that a language shown for a series may not be available in every season or episode. Check the exact release you plan to watch. Its official language-availability guide shows you where to look.

   English, Spanish, Portuguese, French, German, and Italian appear across large parts of the catalog. Languages such as Arabic, Russian, and Hindi have less consistent coverage from one title to another. If Crunchyroll already offers subtitles in your language, try them first. They have been prepared and timed for that episode.

2. Install OMNI and download the languages you need.

   Get the installer from the OMNI Live Translator download page and start the 30-day free trial. No payment card is required.

   Open Languages & Models after installation. If Japanese or your target language isn’t ready, open Get more languages and download the suggested files.

   You can choose Fastest, Balanced, or Most accurate. You don’t need to understand the technology behind these choices. OMNI picks the right setup for your PC.

3. Select Japanese as the source and choose your targets.

   Set the source language to Japanese when the episode uses Japanese audio. Choosing it yourself is helpful because anime may include English attacks, made-up words, songs, and unusual names. These can make automatic language detection less reliable.

   Choose one target language for normal viewing or two for a bilingual layout. For example, you could show English and Spanish together. A multilingual household might prefer Portuguese and French. OMNI places both translations side by side for each spoken phrase.

4. Choose the right speed and accuracy setting.

   Start with Most accurate if you have a capable NVIDIA graphics card. Anime dialogue can be fast, emotional, and full of fictional names. The most accurate setting gives the app its best chance of following it.

   Try Balanced if the captions begin to fall behind the dialogue. Choose Fastest on a less powerful PC or when quick captions matter more than catching every name perfectly. OMNI makes the technical choices for you, so there’s nothing to match by hand.

5. Make OMNI listen to the sound from your PC.

   Select the watch-anywhere option that listens to your PC’s playback audio. Then start the Crunchyroll episode. OMNI hears the same sound you hear from the website or desktop app. It does not upload that sound.

   Keep Japanese selected as the audio language in Crunchyroll. If Crunchyroll is playing an English dub while OMNI expects Japanese, the captions may turn into nonsense. A wrong source-language setting is my first check whenever live captions suddenly stop making sense.

6. Place the caption window over Crunchyroll.

   Open OMNI’s movable caption window and turn on its always-stay-on-top option. Place it near the bottom of the video without hiding important text or action. Resize the Crunchyroll window if you need more room.

   Crunchyroll lets you change its own subtitles through gear icon → Subtitles/CC, as shown in its subtitle settings instructions. Turn Crunchyroll’s subtitles off if the two sets of captions cover each other. Some Japanese-audio titles require subtitles to remain visible in certain regions. In that case, move OMNI’s captions above them.

   If you stream with OBS, OMNI also gives you a browser-source URL. A browser source is a way to show a web page inside your stream. In OBS, choose Sources → + → Browser, paste the URL, and place the captions over the Crunchyroll video in your scene. A scene is the layout your viewers see. If you’re only watching for yourself, OMNI’s normal caption window is easier.

7. Test one minute of real dialogue.

   Start OMNI and play a scene with plenty of conversation. Watch for captions that are very late or broken into awkward pieces. On a gaming PC with a modern NVIDIA graphics card, the first captions can appear in under a second. A complete translation may take a little longer because OMNI waits for the end of the sentence.

   That short wait helps produce a clearer translation. A character may pause for breath without finishing their thought. Waiting briefly lets OMNI keep both parts together. I would rather wait a moment than read a confident translation of half a sentence.

   If the captions keep slipping farther behind, change from Most accurate to Balanced. If the timing is good but a fictional name is wrong, changing the translation setting may not fix it. The app first needs to hear the name correctly before it can translate the sentence.

8. Keep the setup on the viewer’s side.

   OMNI only listens to audio that your PC is already playing. It doesn’t rip, download, change, or redistribute the Crunchyroll video. Its captions stay on your machine.

   Use it only with content you’re allowed to watch. Keep following Crunchyroll’s terms and regional availability rules. This setup adds live captions and translation for the viewer. It isn’t a way around a subscription or other content restrictions.

Picking languages: Japanese to EN+ES, PT+FR, AR+RU, or HI+EN

Keep Japanese as the source when you’re listening to the original Japanese audio. Choose target languages based on who is watching and whether anyone is studying a language.

For language practice, keep the Japanese voices audible. Put a familiar translation beside the language you’re learning. Japanese levels of politeness and status don’t always translate word for word, so the full sentence matters. A line cut off before desu, masu, or the way one character addresses another may sound quite different from the finished sentence.

The same two-language setup works beyond anime. You can use a similar local setup for real-time Netflix translation or follow the YouTube live-stream translation guide for fast, unscripted speech.

OMNI offers 30+ selectable languages. Its built-in AI translation works with full phrases and sentences rather than swapping one word at a time. Open Get more languages to see which languages you can download and use directly in the app.

Why run translation locally?

Running everything on your PC keeps private listening private. The anime audio, live captions, and translated text never leave your computer or enter a provider’s logs. There’s no cloud trip for each line, no per-minute bill growing during a long season, and no cloud outage stopping the translation halfway through an episode.

OMNI also works offline after setup. The app’s speech recognition and built-in AI translation both run on your PC. Your hardware does the work, which is why a modern NVIDIA graphics card and the right Fastest, Balanced, or Most accurate setting can make a difference.

The main idea is simple: nothing gets uploaded, and there are no monthly or per-minute fees.

How does it compare to Crunchyroll’s familiar options?

Crunchyroll’s own subtitles are the best first choice when your language is available for that episode. OMNI is useful when the track is missing, when you want two languages at once, or when another official translation hasn’t been released.

Fansubs have helped people watch overlooked series and use less-supported languages for decades. Experienced groups can create thoughtful translations. They can also be unpredictable. A season may remain unfinished, terms may differ between groups, and permission to share the files isn’t guaranteed.

Waiting is also reasonable. If official names and wording matter to you, and you can avoid spoilers, a prepared translation may be worth the wait. If you only need English and Crunchyroll already provides it, adding live captions creates extra setup without solving a problem.

FAQ

Can OMNI add Crunchyroll subtitles in my language?

Yes. OMNI listens to the Japanese audio and creates its own captions and translations. It doesn’t depend on the subtitle languages Crunchyroll provides for that episode.

Does it work with both the Crunchyroll website and desktop app?

Yes, as long as the sound plays through the same Windows PC. The normal caption window can sit above either player. Streamers can use the browser-source URL to place the captions inside an OBS layout.

Which setting is best for fast anime dialogue?

Start with Most accurate for fast or stylized speech, overlapping voices, and fictional names. Change to Balanced if your PC can’t keep the captions close to the video.

Can I display two translations at once?

Yes. OMNI can show two target languages side by side. For example, it can translate Japanese speech into English and Spanish, or Arabic and Russian, at the same time.

Is the translation private and available offline?

Yes. The app listens and translates on your PC. No audio, caption, or translation data is uploaded or logged. After you download the languages you need, OMNI works offline.

How much does OMNI cost?

The full app has a 30-day free trial with no credit card. After that, the current launch price is $19.95 for a one-time lifetime license. There’s no subscription or per-minute billing. The license covers one PC at a time and can be moved or reset up to three times.
