I had a friend of mine do a chip that spoke -
He moved to CA and I don't where it is now. But he made me this little shop / speaker thing which would have my BIG voice bellowing things like: What the F are you doing! Get the F out of there!
There were about six phrases like that which would speak in succession. But invariably everyone would be running after two times of me yelling. It was a motion sensor light but it powered this box and speaker he made.
I have never heard of a "buzz bulb" thing.
The conventional view serves to protect us from the painful job of thinking.
