Voki

Just imagine, as a teacher, you have a virtual companion in your class that you mess with each other and make your students laugh and motivate. Voki can make this dream come true. Through this app, you can create an avatar, write its lines and give it a voice. It is not very developed and some of the features are not free but it still can create a chance to clear the air for a second when students get bored or tired.

I prepared an avatar, a bulldog named "Snoop Dog" check this out!
