VTava

VTava is a lightweight avatar overlay for streaming.

Use your own PNG images or a webcam with the built-in editor to create avatar states. Push-to-Talk or Always Listen syncs the avatar’s mouth with your microphone, while hotkeys let you quickly switch emotions.

The transparent overlay is ready to use with OBS.

Cross-platform support is planned for future releases: Windows, macOS, and Linux.

Interface languages: EN, RU, HU, DE

PS 

If Windows shows a SmartScreen warning:

1. Click "More info"

2. Click "Run anyway"

I would be very happy to hear your feedback and suggestions
