This diphthong is an essential part of the English language and is commonly found in words like "boy," "choice," and "voice."

This lesson will guide you through the process of producing the /ɔɪ/ sound and provide you with helpful tips and practice recommendations. Let's dive in and master this fascinating sound!


Introduction


1. **Understand the diphthong**: The /ɔɪ/ sound is a diphthong, which means it is a combination of two vowel sounds that blend together. In this case, the sound starts with /ɔ/ (as in "law") and transitions to /ɪ/ (as in "bit").

2. **Position your lips**: To produce the /ɔɪ/ sound, begin with your lips rounded and slightly apart, as if you're about to say the word "law."

3. **Create the first vowel**: While maintaining the rounded lip position, produce the /ɔ/ sound. Your tongue should be low and slightly pulled back in your mouth.

4. **Transition to the second vowel**: As you continue producing the /ɔ/ sound, gradually unround your lips and move your tongue forward and up towards the roof of your mouth. This will help you transition to the /ɪ/ sound. Be sure to maintain a smooth, continuous sound as you move between the two vowels.


## Practice Tips

- **Don't skip the glide**: One common mistake learners make is to pronounce the /ɔɪ/ sound as two separate vowels, rather than a single, smooth diphthong. Be sure to glide from the /ɔ/ sound to the /ɪ/ sound without a noticeable break in between.

- **Pay attention to lip rounding**: Another common error is not rounding the lips enough for the initial /ɔ/ sound. Ensure that your lips are rounded and slightly apart when you begin pronouncing the diphthong.

Remember, practice makes perfect! By following these instructions and tips, you'll be well on your way to mastering the American English /ɔɪ/ sound.
