My school recently allowed me to upgrade to the teacher account ($25 a year), and I have been spending time recording myself saying each of the phrases or words.
This is really great for helping students with listening, and pronunciation.
It is a drill study tool, however, it has merit in engaging students on different levels, just to get familiar with their vocabulary, so they can use it during class. As incentive for the students, I will be setting up an interclass competition next term and getting students to test each other in class.
