It wasn't that difficult, you kind of learn English along the way. However, since you do not listen/talk, you don't know how words are actually pronounced. So you just guess, and it's often wrong. Like I once thought "value" is pronounced "vuhloo" (stress on 2nd syllable). Sadly there's still many engineers in the country (including seniors) who never bothered learning English properly, so they mispronounce everything all the time. They know what all the words mean, but they don't know how they're pronounced, or how to use them in a sentence.
