Say you're looking up the Möbius strip on Wikipedia and you wonder how it's pronounced. Wikipedia only shows some elaborate pronunciation guide written in the International Phonetic Alphabet. You could start googling it in another tab, but there's an easy way to translate that pronunciation guide into plain English. Just hover over the letters.
Hover your cursor over each letter, and Wikipedia will pop up a little explanation, like 'o' in 'code'. You can also click the pronunciation to see a chart matching every special character to its plain-English definition.
Non-English IPA spellings are tougher, as those guides usually don't have the hover feature. But you can still click them to get a full explanation of that language's sounds in the IPA, then translated into English.
You can always just google [word] pronunciation, but you might end up with one of those parody YouTube accounts.
