外教教你学英语音标 双元音[ɔɪ]

/ɔɪ/ is a diphthong sound, and remember a diphthong is two vowel sounds that blend together so they almost feel like one.

Notice the movement in my tongue. /ɔɪ/, /ɔɪ/.

The tip of the tongue is relaxed and touching behind the lower front teeth for all vowel and diphthong sounds.

To make the /ɔɪ/ sound, you need to start by releasing your jaw.

Release the back of your tongue and bring the lip corners slightly forward like this, /ɔ/.

And then, move the front of the tongue up toward the gum ridge to the /ɪ/ position.

The second part of the diphthong is always shorter than the first, but you must make both sounds.

We'll start slowly and then we'll blend them to a normal pace.

/ɔɪ/, /ɔɪ/, /ɔɪ/, /ɔɪ/, /ɔɪ/, /ɔɪ/, /ɔɪ/.

A common challenge with the /ɔɪ/ sound is that the speaker will neglect the second part of the diphthong.

This results in the /ɔɪ/ sounding like /oʊ/.

So let's practice each of the two sounds in the diphthong, separately and then together.

Drop your jaw and the back of your tongue and bring your lip corners forward /ɔ/, /ɔ/, /ɔ/.

Now, let's try the /ɪ/ sound. Match your sound with mine /ɪ/, /ɪ/, /ɪ/.

Now, let's put them together. /ɔɪ/, /ɔɪ/, /ɔɪ/, /ɔɪ/, /ɔɪ/.

Now, let's compare /ɔɪ/ with /oʊ/.

Feel the difference between the two sounds as we try them together.

She sold the soiled clothes.

Most cookies are moist.

That cold snake coiled up.
