If you are a normal American, then you pronounce words like king, ring, and sing just as they appear. You also pronounce progressive verbs that end in ing, such as running and being, are essentially pronounced een at the end of the word, basically rhyming with seen, mean, lean, etc. There are some dialects of English where the g can barely be heard in progressives, but in contemporary English this is gone. The informal is to pronounce the ing not like een, but like in, thus rhyming with words like sin or fin. English only has a specific number of strict sounds that are pronounced, while dictionaries will include additional sounds, they are pretty much gone from most common dialects and accents of English. You will be considered a jerk, if you make a habit of trying to pronounce contemporary English words in archaic ways. English has evolved, this is why the word knight, which was once pronounced with the k sound, the gh was a throaty sound, and the I was pronounced like an e, is now pronounced like nite, but the old spelling managed to stick.
