Voice and captions together

Test before streaming
Run the Live start check and confirm audio routing and caption output before going live.
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

Rehearse with the free version and test streams first (the free version translates into English only, with Live sessions of up to 10 minutes). Latency and accuracy vary by hardware and audio conditions.
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.
