Allow me to make my unpopular opinion all the more unpopular. English should instead have diacritics for such cases. Like, I know, it does, sort of (naïve, façade, etc.) but nobody uses them and they aren’t common enough for all the wildly exotic pronunciations of things. Use them! Add more!

In all fairness, you’re able to distinguish the difference in speech without capitalization using context clues. There are certainly situations where you might have to ask for clarification; while reading you just have to figure out context clues like someone figuring out the meaning of a new word.
