WHAT IS IT?

​Pronunciation:
The sound /ɑɪ/ is a diphthong. This means your mouth should move from one position to another.
  • Lower your jaw and tongue and make your lips very open and wide (as for /ɑ/). Your tongue should be low, tight, and pulled backwards.
  • Breathe out and let your vocal cords vibrate.
  • As you breathe out, quickly raise your tongue and spread your lips widely (as for /ɪ/).
