The /aɪ/ sound — i as in my
In short
/aɪ/ is a closing diphthong: glides from open /a/ towards /ɪ/ — the diphthong you hear in my, time, eye. Like every diphthong, the glide between two positions IS the sound. Below: exactly how to position your mouth, audio you can copy, the mistakes learners actually make, and drills to fix them.
How to pronounce /aɪ/
- 1Open your mouth wide for the /a/ start.
- 2Glide up towards /ɪ/, closing your jaw as you go.
- 3One smooth sweep: my, time, why.
Sounds like: the word 'eye' / the letter I
/aɪ/ in words — with audio
Listen, then copy. The slow (turtle) version exaggerates the mouth movement.
- my/maɪ/ · sound is final
- time/taɪm/ · sound is medial
- eye/aɪ/ · sound is initial
- high/haɪ/ · sound is final
- buy/baɪ/ · sound is final
- quite/kwaɪt/ · sound is medial
The mistake almost everyone makes
Cutting the glide short so 'like' sounds close to 'lack', or over-lengthening the first part. Both endpoints must be heard.
