/ɔɪ/

· ·

Two-sound vowel: starts with 'o' then glides to 'i'. Like 'oy' in 'boy'.

Example words

coin 
boy 
choice 
voice 

How to make the sound

Start with an open rounded vowel and glide upward and forward toward a close front position.

What to feel and listen for

The lips begin rounded and relax as the tongue moves forward. Keep it as one connected glide.

Common mistake: Keep the start rounded; relaxing the lips early turns /ɔɪ/ toward /aɪ/ (boy → buy).
