I recommend all learners of English to learn the phonetic symbols and then use that knowledge to help with pronunciation. The 44 internationally recognised symbols plus 2 others are written at the bottom of nearly every page with an example word under each symbol. The majority of the example words are one syllable and words that are in frequent use so they are very easy to learn. The symbols and words only take up 4 pages so the pronunciation aid is always close to hand.
This dictionary has been replaced by The Oxford Essential Dictionary which does not have the pronunciation aid - what a pity!
