A, E, I, O and U are called vowels.
Vowels in German are pronounced differently according to whether the vowel is short or long. A vowel is short when it's followed by a consonant cluster, otherwise it's long. It’s a bit different from English, where the vowel a in the English word cat is short whereas the a in farmer is long.

How to pronounce German Vowels
| Vowel Sound | Approximate English Sound | German Example |
|---|---|---|
| a | cut | kalt (cold) |
| a_ | harm | sagen (to say) |
| e | belt | Geld (money) |
| e_ | need | Regen (rain) |
| i | hit | Insel (island) |
| i_ | meet | Igel (hedgehog) |
| o | got | offen (open) |
| o_ | note | Boot (boat) |
| u | foot | rund (round) |
| u_ | moon | rufen (to call) |
Like in English, German vowels are pronounced with a pure sound when they are stressed, but they tend to glide towards the "schwa" sound when they are not. Take Regen for example: the first -e- is stressed, so it's a pure sound, but the second -e- is pronounced with a "closer" sound.
German vowels A, O and U can also carry an umlaut, which is represented by two dots: Ä, Ö, Ü. The umlaut changes the way these vowels are pronounced.
Ä - eh
Ö - as the "i" in "girl"
