Real-time voice translation for games and voice chat
Windows app for games and Discord. Translate other players' speech into subtitles, and your mic into their language — with a focus on low latency. Run speech recognition locally with Whisper on your GPU, or bring your own API keys.
Get startedWhat SyncLingo does
Two-way translation
Understand other players and be understood: their speech becomes subtitles in your language, your voice reaches them in theirs.
In-game subtitle overlay
Live subtitles on top of the game — no need to alt-tab or read a separate window.
Low latency
Tuned for speed over perfect accuracy, with streaming recognition where the provider supports it.
Local & private option
Run speech recognition on your own GPU with local Whisper (NVIDIA/AMD/Intel) — no STT cloud, no per-use bill.
Your providers, your keys
Swap STT/translation/TTS between Deepgram, AssemblyAI, OpenAI, ElevenLabs, DeepL, Google, or local Whisper & Windows voices. Keys stored locally.
Lightweight Windows app
A small native Windows 10/11 app (Tauri, system WebView) — not a heavy Electron build.
How it works
Incoming — understand others
SyncLingo captures game/Discord audio, transcribes and translates it, and shows subtitles (and optional spoken audio) in your language.
Outgoing — be understood
You speak into your mic; listeners hear your voice in their language, routed through a free VB-Cable virtual microphone.
FAQ
Does it work with Discord?
Yes. SyncLingo captures system audio, so it works with Discord, in-game voice chat, or any app — and sends your translated voice back through a virtual microphone.
Which games does it support?
Any game. It captures system audio (loopback), so it isn't tied to specific titles.
Which operating systems?
Windows 10 and 11 (desktop app).
Is there an offline / private mode?
Speech recognition can run fully offline on your GPU with local Whisper. Translation uses Google (free) or DeepL, and text-to-speech can use local Windows voices — so with local Whisper + Windows voices, only the text to translate is sent to the translation provider.
How much does it cost?
A license: $5 for 3 months, $9 for 6 months, $15 for 12 months. You also pay for any cloud STT/MT/TTS you use — but a local-Whisper + Windows-TTS + free-Google-translate setup adds nothing beyond the license.
Which languages?
Whatever your chosen translation provider supports (Google Translate or DeepL cover dozens of languages).
Does it add lag?
Translation always adds some delay; SyncLingo optimizes for low latency and uses streaming recognition where available.
What do I need to set up?
Nothing extra to hear others. To let others hear you, install the free VB-Cable virtual device and pick it as your mic.
