English is fraught with pronunciation and spelling challenges. Our accent modification clients are often puzzled with these RULES. Here is another tip to help you or your clients or students in the ESOL classroom decipher some of the mysteries. A diphthong (pronounced "dif-thong") is a combination of two vowels. The letter combinations “oi” and “oy” are diphthongs and sound alike. The “oi” spelling is usually found in the middle of words, and the “oy” spelling typically occurs at the end. Of course, there will be exceptions to this rule.
When producing this diphthong, keep the tip of your tongue on the floor of your mouth, right behind your lower teeth. Your tongue is slightly lower than for the /o/ vowel. Round your lips slightly. Then shift to the high /I/ vowel by retracting your lips. Lift the tongue blade high in your mouth and move it toward the front of your mouth. Press the sides of your tongue against your upper teeth (molars). [audio wav="http://www.eslrules.com/wp-content/uploads/2014/01/oi-vowel.wav"][/audio]
