Voicethread - a good practice tool for the TOEIC Speaking Test

Voicethread is a tool I recently came across that looks promising for my EFL English class at my University. I am presently teaching a TOEIC Speaking Test Prep class, and one of the questions on the test involves describing a picture. Students need to describe what is happening in a picture, and also make speculations about what is happening in a picture. Voicethread will be a good way for me to assess my student's punctuation and descriptive skills. I'm excited to see what other ways I can use it in the classroom.
