I found many databases with most of the german words, but non of them contained the pronunciation of the words. (In Phonetic spelling) Something like:
Hund - Húnd OLivenbaum - oˈliːvn̩ba͜um
would be great.
Wiktionary is also not suffient, as it can not be easily parsed by a computer. Best case would be if the dataset would be free, but it does not have to be.
