Check source and translation
Captions make it easier to inspect what was recognized and translated before relying only on generated voice.
Live Translation Captions
Turn live voice into translated captions you can check.
VoxShift is not only about translated speech output. It also shows real-time AI subtitles: the Live screen keeps the line being spoken in “Now” and finished lines in “History”, newest first. Captions can also appear in the built-in subtitle window, with no browser needed, or in a stream layout through OBS WebSocket text source updates.

OBS text source workflow
Use OBS WebSocket to update text sources with translated captions for stream overlays and recordings.
Rehearse before going live
Caption timing, line breaks, latency, and GPU load vary by setup. Test with the free version before production use.
Fit Check
Where VoxShift fits, and where it does not.
Good fit
- You want translated speech output for Discord, game VC, or OBS streams
- You need more than subtitles and want your voice chat partners to hear translated speech
- You want to test GPU, VRAM, audio devices, and latency with the free version first
Use caution
- You need zero-latency simultaneous interpretation or perfect speaker separation
- You need high-stakes medical, legal, financial, or emergency translation
- You plan to use another person's voice without clear consent
- You want Live voice translation on an AMD Radeon, Intel GPU, or no-GPU PC (setup and diagnostics only)
Setup Flow
Check this flow before you buy.
Live voice translation requires an NVIDIA CUDA GPU (GTX 16 / RTX 20 series or newer) with 4 GB VRAM or more, and results also depend on your audio devices and routing. Test the free version (Steam Demo or Microsoft Store free trial) on your own PC before purchasing. It limits each Live session to 10 minutes, translates into English only, uses a fixed light model set, and allows up to 3 soundboard items.

FAQ
Common questions
Is this the built-in Windows Live Captions feature?+
No. VoxShift is a Windows app for voice translation and caption workflows. It is separate from OS-level live captions.
Can I use captions without translated speech?+
You can use caption checking as part of the workflow. VoxShift is strongest when captions, translated speech, and routing are tested together.
Can it translate system or desktop audio?+
Yes. Partner subtitles listen to the other side's audio, such as a call, game, or video, and show it as translated captions. App-specific capture and source separation depend on your Windows audio setup, so test the free version first.
Can it capture only one specific app?+
VoxShift does not guarantee perfect per-app audio capture or source separation. It depends on your Windows audio device setup, so test the exact app and route with the free version.
Can I use it as a translated caption overlay?+
Yes. The built-in subtitle window shows translated captions on top of other windows without a browser, and for OBS streams VoxShift can update a text source placed as a caption overlay. How it looks can vary by app and display mode, so check it with the free version.
Are captions guaranteed to be accurate?+
No. Recognition and translation quality depend on audio quality, speech, language pair, selected models, and PC performance.
Start with the free version.
Voice translation is highly dependent on your PC. Before buying, check your PC, devices, and latency with the free version. Steam and Microsoft Store sell separate products, each a one-time purchase.
