They are mini-recorders where you can re-record a variety of 10 second messages. They have a little clip on the back so you can clip them on to pictures or other thin objects. I went looking for them after reading the book "Teaching Conversation Skills to Children with Autism: Scripts and Script Fading" as they outline ways to use them when working on conversation skills. I recognize that not all of my students will be able to push the small button to activate them but for the students I'm thinking about right now these are going to be great!
I ordered them from Voice Express. They do have other mini recorder types of products that are worth checking out. I'm planning a future post outlining some of the uses that I found for these little treasures :).
