Oh I see it now. Thanks for the explanation

Yeah I went through them again and see how it makes a slight difference but I am slavic and you can definitely hear it when I speak especially with my þ, ð and r sounds. The r especially after speaking for more than 15 minutees my tongue just gives up and I cannot make the weird soft english version of it. The probounciations I use are all over the place.

It may be pronounced either way, and may also be spelled "broach", an alternate spelling which is very common although probably slightly less than this chart implies given multiple meanings of "broach".

I'm not really informed on this history of this word, but I think it's possible that the "brooch" spelling increased in frequency along with the pronunciation that rhymes with "mooch" while people who pronounce it to rhyme with "roach" are more likely to spell it as "broach".
