Long vowel teams: ai, ay /eɪ/ and ee, ea /i/
Short answer: Some pairs of letters make one long vowel sound. The teams ai and ay say /eɪ/ (rain, play), and ee and ea usually say /i/ (tree, sea). The first team member is often the one you hear, and the team works as one sound. Use ai in the middle of a word and ay at the end.

How to make the sound
- Look for the team: ai, ay, ee or ea.
- Read the team as one sound, not two letters.
- Use ay at the end of a word (play) and ai in the middle (rain).
- Say the long vowel for a little longer than a short vowel.
Examples in sentences
- rain
ai = /eɪ/: /reɪn/. - play
ay = /eɪ/: /pleɪ/. - tree
ee = /i/: /tri/. - sea
ea = /i/: /si/. - train
ai = /eɪ/: /treɪn/. - sheep
ee = /i/: /ʃip/.
Common problems
- Reading both letters: In rain, a and i make one sound, /eɪ/.
- Using the short vowel: sheep is not ship. Keep /i/ long.
- Forgetting exceptions: ea can also say /ɛ/ (head, bread). Check new words.
For Vietnamese speakers
- /i/ in sheep is longer and tenser than /ɪ/ in ship. Smile and hold the sound.
- /eɪ/ glides from /e/ up to /ɪ/. Do not stop at /e/.
