Vowels
- Vowels are determinated by changes in position of the lips, tongue and palate.

- In English, vowels can also glide into (move quietly) one another to form diphthongs and even triphthons.
Diphthongs: centring:
Diphthongs: :
Voiced/ voiceless:
- The level of vibration of the vocal cords determines whether a sound is voiced or unvoiced.
- If the vocal cords are apart, then air can scape unimpeded. Sound produced in this way are said to be voiceless.
- If the vocal cords are very close to…
/i:/

- For example: capilla, Castillo, si (enfático)
