How do you pronounce brezo?
how to say brezo
I would pronounce the z as an "s" sound, so the word would sound like "bray-so". The other suggestion is also correct, however. It depends on where you're from in the Spanish-speaking world (i.e. Spain, Mexico, etc.).
Another way you can find out pronunciation is to look it up in the SpanishDict dictionary and click on the speaker icon.
Try "th" as in "thorough"
