ˈdɔɪ̯tʃə
Here's a breakdown:
* "D" is pronounced like the "D" in "dog".
* "oi" is pronounced like the "oy" in "boy".
* "tsch" is pronounced like the "ch" in "church".
* "e" is pronounced like the "e" in "bet" (but slightly shorter and more open).
So, the pronunciation is like "doy-chuh" with a slight emphasis on the first syllable.
It's worth noting that "Deutsche" is the feminine plural of "Deutsch" (German). When referring to German people as a group, it's always "die Deutsche" (the Germans).
