I wonder when the english (at least American english) pronunciation of robot changed? I sometimes listen to old radio dramas as I fall asleep and the older the show the more likely they are to say "row butt" instead of "row bot."
When I think about old fashiony ways to pronounce robot, the only thing i think of is Zoidberg pronoucning it "rowbit" https://youtu.be/mh5NSmVs_uk?t=26
I know more than a few people who pronounce it "row butt" today. I think it's a regional US dialect thing.
One of the first twilight zone tv episodes, maybe even the first one, featured that pronunciation also.
Isaac Asimov used to say "row butt" but I can't think of anyone else who did/does.
The narrator on many episodes of How It's Made says "row butt"
