Syllables
1. Regular Vowels and Vowels with Umlaut
There are five regular vowels and three vowels with umlaut in German: a, e, i, o, u and ä, ö, ü. a, o, u and ä, ö, ü are pronounced differently.
2. Consonant + Vowel
German vowels vary in pronunciation by longer and shorter sounds.
It's a long vowel when:
-it's on its own;
-it's followed by only one consonant, e.g. "a" in "Vater" is long, and "a" in "Mann" is short;
-it's duplicated, such as "aa" in "Maat", "ee" in "See" and "oo" in "Boot"; the vowel "i" never duplicates. The long sound of "i" appears usually as "ie", like in"sieben".The vowels "u/ä/ö/ü" never duplicate.
-it's followed by "h", like "Huhn" ("h" is muted);
3. Diphthongs and Grouped Consonants
1) Diphthongs (vowel + vowel): au, ei/ai, eu/äu
2) Double consonants
When a consonant is doubled, its sound doesn’t change.
For the consonant “k”, there is no “kk”, but there is “ck”.
3) Grouped consonants
a) "dt" and "th"
b) ph
c) tz, ts
d) chs, x
