An accidentally discovered communication aid?

Books don't last long in this house.  We tend to only bother with board books and even then, they haven't lasted.  Charlie, in particular does like them though, so we bring them out off and on, with an acceptance that they will probably not survive!  He particularly likes the type with the buttons down the sides that make a noise so we were letting him have a few to look through at bedtime for a while.  This particular one was a favourite but in the end got destroyed leaving only this....

I was going to bin it, but then wondered if we could use it?  Its not really a lot different to the electronic speech aids and its all recorded and ready to go. So, I've set it aside for future use and I'm looking out for similar books that could be used for communication about other things. Just got to find more storage space now.....
