3D Human Controlled Avatars?

I’m looking for a real-time, human-controlled avatar software that I can operate from my computer for virtual conversations. I am looking for something that can mirror my speech, repeating what I say, and also capture my facial expressions to provide a more interactive and lifelike experience in real time. I am not looking for AI or recorded capabilities.

I know this kind of functionality exists within certain Zoom features, but it’s not yet widely available. Does anyone know of an agency or service provider that offers this capability, where I can control an avatar in real-time for virtual meetings or presentations?
