What it does TTS Voice Wizard is a Windows desktop app that listens to your microphone, transcribes speech to text, optionally re-speaks it through synthetic voices, and forwards everything to VRChat as OSC messages. Your words (and song titles, heart rate, controller battery) appear on your avatar via KillFrenzyAvatarText, Frosty’s Billboard, or VRChat’s native chatbox. It works outside VRChat too, but that’s not where the fun is.

The interesting bit The project treats VRChat as a live stage rig: voice commands can flip avatar parameters, contact-receiver touch counters increment interactively, and Spotify/Windows Media metadata gets piped to the same text surfaces. It’s essentially a broadcast switcher for your body.

Key highlights

• 100+ TTS voices with per-voice tweaks; premium tier adds Azure, Polly, Google Cloud, IBM Watson, and DeepGram Nova-2 STT
• Real-time translation to 50+ languages (70+ with Pro)
• Spotify/browser now-playing, Pulsoid/HRtoVRChat_OSC heart rate, XSOverlay battery levels
• Voice-triggered avatar parameter control and touch counters
• Scoop installable; auto-updater included

Caveats

• Windows 10/11 only; older Windows explicitly not guaranteed
• Several feature docs and the demo video are flagged as outdated
• Core functionality depends on third-party avatar text systems you must install separately

Verdict Worth a look if you stream or socialize in VRChat and want your avatar to talk, sing along, and bleed status widgets. Skip it if you’re not in that ecosystem — the value is almost entirely in the VRChat OSC glue.
