This guide will help you create a basic and very simple “2-Frame” avatar (Mouth Closed / Mouth Open) that reacts when VoxAI speaks.
How it works:
Before opening OBS, download and install these two required tools.
1. The Audio Driver (Virtual Cable) This allows VoxAI to “talk” directly to OBS without your microphone picking it up.
2. The OBS Move Plugin This handles the animation logic.
3. Your Art You need two PNG images with transparent backgrounds:
Open OBS and follow these steps exactly.
A. Add the Images
B. Add the Audio Source
This is where the magic happens. We will tell OBS: “When the audio gets loud, show the open mouth.”
| Setting | Value |
| :— | :— |
| Meter Type | Magnitude |
| Easing | 0.00 |
| Action | Source Visibility |
| Scene | (Select your current Scene) |
| Source | (Select your Mouth OPEN image) |
| Threshold Action | Enable Over and Disable Under |
| Threshold | 0.05 (Start here, then adjust until it looks right) |
Pro Tip: If the mouth isn't opening, lower the Threshold. If it gets stuck open, raise the Threshold slightly (e.g. to 5.00 or higher depending on volume).
Now tell VoxAI to use that special cable we installed.
Can't hear the bot?
This is because the audio is going to the Virtual Cable, and not going to your speakers (as intended). To hear it yourself:
Note: You will not be able to hear your bot unless OBS is open. This is because the audio source is not playing anywhere else where you can hear it.
