The latest use of avatars in instant messaging is dominated by dynamic avatars. The user chooses an avatar that represents him while chatting and, through the use of text to speech technology, enables the avatar to talk the text being used at the chat window. Another form of use for this kind of avatar is for video chats/calls. Some services, such as Skype (through some external plugins) allow users to use talking avatars during video calls, replacing the image from the user's camera with an animated, talking avatar.
