What does Trannel mean?
Translating Real-time Audio – Naturally, Near-instantly, Everywhere, Locally

It translates what you hear, live – naturally, within seconds, everywhere and entirely on your PC.

Features

Understand and be understood

No cloud, no forced subscription, no waiting. Install and go – 30 minutes free every week.

Understand others

Translates everything that comes out of your speakers – YouTube, Discord, games – or, if you like, only one specific app.

Speak – in any language

You speak English, Trannel says it in your friends' language on Discord and in game chats. With push-to-talk (hold a key = translate) or always on.

Natural voices

No robot sound: natural voices for 13 languages, including English, Japanese, Chinese and Thai – running offline on your PC.

Overlay for games

Always on top, freely movable, adjustable font. F8 shows it, F9 makes it click-through.

100% offline & private

Speech recognition and translation run entirely on your PC. Neither audio nor text ever leaves your computer.

Fast, with GPU support

Recognition and translation run in parallel. With an NVIDIA or AMD graphics card the app automatically uses the larger, more accurate model. Three quality levels: Fast, Balanced, Best.

16 languages + Thai & 中文 boost

Automatic language detection. For Thai and Chinese there are additional, especially accurate specialist models.

Automatic updates

The app tells you about new versions itself – one click and it updates and restarts.

30 minutes free every week

No sign-up and no payment details – with every feature. A license removes the limit.

FAQ

Frequently asked questions

What can the free version do?

Everything. Without a license, live translation runs 30 minutes every week – with every feature, language and voice, no sign-up and no payment details. When the minutes are used up, it continues on Monday, or you buy a license and translate without limits.

How do my friends on Discord hear my translated voice?

Trannel speaks the translation into a virtual microphone. For this you need the free VB-Audio Virtual Cable (vb-audio.com/Cable). Trannel switches the microphone itself while “Voice for Discord” is on and switches it back when you turn it off – your Windows and Discord settings stay unchanged otherwise.

How big are the natural voices?

The first time, the app downloads a natural voice for the selected language, about 110–380 MB depending on the language. After that it runs offline. For languages without a natural voice (Turkish, Korean, Arabic) Trannel uses the Windows voices.

How accurate is the translation?

Speech recognition and translation are produced by AI models and are usually very easy to understand, but they can contain mistakes. The app is not intended for medical, legal or safety-critical conversations.

Can I cancel my subscription?

Yes, at any time to the end of the billing period – via the link in your purchase email. The Unlimited license is a one-time purchase without a subscription.

On how many PCs can I use the license?

On up to 2 PCs at the same time. Under “Manage license → Deactivate on this PC” you can free up a seat at any time.

What happens to my audio?

Nothing. Speech recognition and translation run entirely locally on your PC. Neither audio nor text is uploaded or stored. The app only goes online briefly to check the license and look for updates.

Why does Windows show a warning when installing?

Windows SmartScreen doesn't know new programs without a paid code-signing certificate yet. Click “More info → Run anyway” to install. The SHA-256 checksum in the download section confirms the file is unmodified.

Can I see the overlay in full-screen games?

Yes, in games running in “borderless window” mode. In exclusive full screen, Windows can't put other programs' windows on top.

Which PC is recommended?

Windows 10 or 11 (64-bit), 8 GB RAM and a recent 4-core processor. With a graphics card it gets even faster and more accurate: NVIDIA (GeForce/RTX), AMD Radeon RX or Intel Arc. The setup detects your card and offers the right acceleration.

How do I uninstall the app?

Windows Settings → Apps → “Trannel” → Uninstall.
