    I remember toys with a plastic strip that had embossed lines running 
across them. When pulled across a fingernail it would make some sound, 
very short like a doll saying "Mama". I have no idea how these were made.
    I also remember reading about a method of placing embossed grooves 
on the street so it would "speak" when driven over, safety message or 
maybe short advertising. A google search might find both, I have not tried.
