What is Voki?
This is Voki! I made the above example in about 5 minutes using the text to speech function. Think of the applications in the classroom and on your web site! Want to introduce a musical concept in a fun, new way? The text to speech portion of Voki will let you do just that.
Another free and ever-expanding text-to-speech site is a branch of youtube: Youtube/Create. Both GoAnimate and Xtranormal Movie Maker are great online text-to-speech video creation editors built in to the sites that allow you to hear spoken whatever you decide to type. Youtube/create allows for 2 people to hold a conversation back and forth between each other, making for a more natural dialogue to present your ideas/concepts to a classroom, rather than 1 person just talking to them - which is more lecture-like. Dialogues can be more humorous and make the listeners feel like they are witnessing witty banter between 2 people, rather than 1 person jabbering away.
Here is a quick example of the 2-person dialogue options in GoAnimate!
Happy video creation!
