As you can see, I have created my very first Voki. Completing this task was much more bearable that I originally thought it would be. The only real trouble I had was choosing which character to utilise!
I'm not too sure how we could use a Voki within the classroom, except to excite the students a little bit more, and perhaps make them engage in the activity better.
I don't personally think I would use a Voki in the classroom, as I don't really see the point. A Voki only does what you tell it to do, thus just making it more work to be completed for 15 seconds of fame.
Also, I found that out of all of the voices that you had to choose from, none of them were particularly easy to understand and hear. The voices were all quite computer-ish (sorry, just putting in my own words here), and kind of metallic. I know that I do not have any hearing difficulties, and I had trouble hearing it, and I just thought of the student's that do have hearing difficulties, how much trouble they would have hearing what the Voki has to say.
If you were to utilise a Voki within the classroom, you would have to take into consideration the voice that you use (and the type of difficulties any students in your classroom have) and also the time constraints you have when using a Voki.
