Voice, calls, and the video avatar
Voice messages, calling a character, and the living portrait.
A character has their own voice. A voice note in chat and a call spend minutes from the plan's monthly quota. Free has no such quota, so a call is unavailable. Speech on a call is turned into text so the model can answer. Minutes past the quota cannot be bought.
The video avatar is not a clip from a text prompt. It is a living portrait of the character, shown in the chat and on the profile.
