Translator for Rocket League – understand your teammates live

Typical situations in Rocket League

• Party chat on Discord with teammates from other countries during ranked.
• Terms like boost, demo, kickoff or aerial stay as they are.
• Following esports casts and coaching videos in other languages.

Set up Trannel for Rocket League

1. Install Trannel and start it – 30 minutes are free every week, no sign-up.
2. Choose System audio as the source. If you only want one app, pick just Rocket League or just Discord.
3. In the Rocket League video settings choose a borderless display mode (in Rocket League it is called “Borderless”) instead of exclusive fullscreen – only then can Windows show the overlay above the game.
4. Press F8 to show the overlay and F9 for click-through, so your mouse goes to the game.
5. Pick the language you want to read – Trannel detects the spoken language automatically.

Rocket League terms stay as they are

Trannel recognises when Rocket League is running and keeps the words players actually say – such as Rocket League, Octane, Fennec, Dominus – unchanged instead of translating them literally.

Translating into Chinese on a PC with a graphics card? 中文 Plus translates English, Japanese and Vietnamese into Chinese more naturally, including gaming slang.

Answer in their language (Beta)

With “Voice for Discord” you speak your language and your Discord group hears you translated, with a natural voice. The feature is in beta and only in the version from trannelapp.com.

Offline and separate from the game

Speech recognition and translation run on your PC; audio and text are not uploaded. Trannel does not modify Rocket League or inject anything into it – it listens to Windows audio and shows its own window.

Rocket League is a trademark of Psyonix / Epic Games. Trannel is an independent app and is not affiliated with, endorsed or sponsored by Psyonix / Epic Games.

Frequently asked questions

Is Trannel free for Rocket League?

Yes. Trannel runs 30 minutes free every week – with every feature, no sign-up and no payment details. Licenses will be available soon.

Why don't I see the overlay in Rocket League?

In exclusive fullscreen Windows cannot draw other windows above a game. Switch Rocket League to a borderless display mode (in Rocket League it is called “Borderless”) and press F8.

Which languages does it translate?

20 languages, including English, Spanish, Portuguese, Russian, Japanese, Korean, Chinese, Thai, Vietnamese and Turkish – in every direction.

Does Trannel touch the game files?

No. Trannel only listens to Windows audio and draws its own overlay window; it does not change or read Rocket League's files. Whether third-party tools are allowed is up to Psyonix / Epic Games's rules.

Do I need a graphics card?

No. Trannel runs on the CPU; with an NVIDIA, AMD or Intel graphics card it is faster and can use more accurate models.
