How we make front vowel sounds:

1. The mouth is open a little or a lot.
2. The tongue is near the front of the mouth.
3. The tongue is high, mid-high, mid-low, or low in the mouth.
4. When vowels are high, the mouth is only open a little. The lips are close together.
5. When the vowels are low, the mouth is wide open and the lips are far apart.
