Questions about the AI avatar

Good afternoon! My name is Varvara. I am a representative of the online University of Artificial Intelligence. We teach students neural networks and are a development company. We have several questions about your service, namely questions about creating an AI Avatar and its implementation.

Tell me, please, is it possible to place the created avatar in a Web application, please tell me where I can read how to do this?

And when placed in a Web application, is it possible to make the avatar pronounce this text with certain reactions in real time when submitting audio /text?
At the same time, is it possible to take default reactions or should they be modeled?

If there are tariffs, which tariff should I choose, taking into account our need: posting on the site and voicing the text / the reaction of facial expressions to the voice, as if he himself spoke with this voice?

Thanks for your reply
