Actually, you generally can. I mean, if I were to type askrillengtauntabuler and to ask you to pronounce it, you'd probably come out with the same phonetics that I used to write it down.

The problem English has with pronunciation is that we have a habit of insisting on importing foreign words with foreign pronunciations and insisting that they be spelled with their foreign spelling. Even if the source language isn't written in Latin script. (Bonus points for people who insist on using foreign case rules for converting to plurals, and double bonus points for people who do it wrong and insist that the wrong way is the most correct spelling.)
