Real-time voice translation for games & voice chat
Windows app for games and Discord. Their speech → your subtitles; your mic → their language — tuned for low latency. Run recognition locally with Whisper on your GPU and speak with Windows voices — only the text to translate leaves your PC.
Two-way translation
Their speech becomes subtitles in your language; your voice reaches them in theirs. Enable one direction or both.
In-game subtitle overlay
Transparent, always-on-top, click-through subtitles over the game — no alt-tab, no second window.
Global hotkeys & PTT
Start/Stop, push-to-talk, push-to-send, live-voice toggle — all without leaving the match.
Local & free Whisper
Run recognition on your own GPU (NVIDIA/AMD/Intel). No STT cloud, no per-use bill — $0 recognition.
Windows voices, offline
Speak translations with built-in Windows voices — no key, instant, nothing sent to the cloud.
Your providers, your keys
Swap STT / MT / TTS between Deepgram, AssemblyAI, OpenAI, ElevenLabs, DeepL, Google or local. Keys stay in Windows Credential Manager.
Text mode → chat
Translation copied to your clipboard — paste straight into a text chat. No audio sent.
Single-app capture
Capture the whole system, or just one app — teammates' voice only, your music and notifications ignored.
Bring your own engines — or run it local.
Pick a provider per stage and per direction. Two stages have a free, offline option; translation is the only stage that always uses the cloud — and only the text is sent.
With Whisper STT + Windows voices, only the text to translate ever leaves the machine. Everything else runs on your PC.

Run it without leaving the game.
Global hotkeys work in-game. The overlay is fully stylable — font, size, color, background, opacity, outline, alignment, max width, auto-hide — with a per-phrase latency breakdown under each line. Each direction is a separate, draggable block.
That breakdown counts the phrase itself (rec), so most of Σ is how long the person spoke. What you actually wait after they stop is stt + mt — around a second on a local GPU, less on a cloud engine.
SyncLingo captures system audio (or one chosen app), transcribes and translates it, and shows subtitles — plus optional spoken audio — in your language.
You speak into your mic; listeners hear your voice in their language, routed through a free VB-Cable virtual microphone. Flip to live-voice with a hotkey to pause translation instantly.

license from $10 · cloud usage billed by your own providersA local-Whisper + Windows-TTS + free-Google-translate setup adds nothing beyond the license. Cloud STT/MT/TTS are billed by your own providers.
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: $10 for 3 months, $15 for 6 months, $25 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.
