Do you ever mispronounce words as they are spelled?

I was a really big reader when I was younger (although I still am, it was more impressionable back then) and as a result I tend to pronounce the words as they are spelled, not as they are spoken. For example, I once pronounced the word “Chile” as “Ch-aye-l.” Also, I said “courtesy” as “core-teh-esee” instead of “curt-eh-see.” My family and friends will never let me forget these moments, and I was interested to hear if this has ever happened to you. Do you ever misprononce words as they are written?

If it helps (accents), I live in New York.
