  2. Diphthongs • Diphthongs have a prominent shift in resonance, usually in the form of an off-glide • EX: boy, how, view • There’s a change in the adjustment of the vocal tract that takes place as diphthongs are produced • Combination of 2 vowels • The initiating target is the first vowel • The terminating target is final vowel
