Mrs Weiss features talking heads apps on her post and wonders briefly about student responses in learning and how these can be captured. She mentions a range of animals, birds, robots and also a gingerbread man that has a talking head. Most of the ones she has found are free:
The premise is simple. You talk, the app records what you say and repeats it back. You can record this little exchange to make a little movie of the animal saying what you say. You only hear the repeated part on the video
She includes a range of ways that talking head apps can be used.
