Pronunciation vs spelling, meaning distinction, addition of sounds

In our language many words are written as they are pronounced, but in some words pronunciation and spelling differ. For example, in the word «kitob» (book) a sound like p is heard at the end, while b is written. The word «do‘st» (friend) is often pronounced without the final t, as «do‘s», but in writing the t must be written. In «oila» (family) a y sound is heard between the vowels but is not written. So a word must be written according to spelling rules, not as it is heard. Checking hard words in the spelling dictionary is a good habit.
