Drawing and recording your voice is not an easy task. What I've discovered is that once you start drawing, and your focus shifts to the image, there are few barriers to speaking.
The tool I'd like to share today is EDUCREATIONS . I haven't explored it to its full potential but what I've seen so far is good enough. The free tool allows you use your mouse or your finger (ipad) to draw stick figures while you record your voice. You can also upload an image and draw and record your voice at the same time. Once finished, look at the right side below the twitter and facebook buttons for the URL and the embed code which allows you publish the recording.
This is a tutorial I've created showing how to make your Draw + Speak recording.
These are some example recordings made by EVO participants:
