But occasionally, it happens that I still get it wrong. For example, just a few weeks back, I've heard 'Arkansas' pronounced in the News - totally different than I would have pronounced it. I know how to pronounce 'Kansas', and I was always under the impression that 'Arkansas' is the same with an 'Ar-' prefixed, which is apparently not the case.
Since it hasn't been mentioned yet in this thread: https://youglish.com/ is absolutely brilliant to figure out how something is pronounced, saved me quite a few times already of mispronouncing things.
