Communication method and device based on virtual video head portrait

The invention provides a call method and device based on a virtual video head portrait, and relates to the technical field of communication. And when the first user terminal does not respond to the call request from the second user terminal, the server establishes a call connection with the second user terminal, searches a virtual video head portrait associated with the user identity from a database, carries the virtual video head portrait in a call forwarding response, and sends the call forwarding response to the second user terminal. And the server determines second voice data and a display state of the virtual video head portrait in response to the first voice data from the second user terminal. And the server sends the second voice data and the display state to the second user terminal, so that the second user terminal plays the second voice data and displays the virtual video head portrait according to the display state. Therefore, the first user terminal realizes video call interaction with the second
