Ukrainian and russian words often use the same letters but are pronounced very differently due to distinct phonetics. On the other hand, some Polish and Czech words sound the same or very similar to Ukrainian but look quite different because of their different alphabets. Therefore, phonetic transcription would be a valuable improvement.
I've been using phonetic transcriptions in a parallel text reader application I've been putting together. It seems like they go a long way in allowing a foreign language learner to internalize a word's pronunciation.
