The Chinese characters “坳幼” are pronounced as “ào yòu”. In English pronunciation, “ào” can be approximated as “ow” as in “cow” with a long “o” sound. “yòu” is similar to “yo” as in “yoyo” followed by “oo” as in “boot”. When pronouncing these two characters together, make sure to give a clear distinction between the two sounds. Try to practice saying them slowly at first and then gradually increase the speed. This will help you master the pronunciation better.
