I need to know the name of a toy from the 90's. You could record your voice on it and play it back but it was electronic and did not require a tape. I think it was something along the lines of "yack back" or "talk back". Please help I really want to know what it is. Thanks

Here's info about the inventor and a little bit about how it worked:

There was one called the Talk Back. It was used in Home Alone 2 Lost in New York. Hope this helps!
