[YurgenJurgensen]

"Zeitgeist" seems like a bug, I've never heard anyone pronounce the leading 'z' as 'ˈts' in English, and doing so as a non-German might even be seen as 'over-pronuciation'.

[eesmith]

https://en.wiktionary.org/wiki/zeitgeist#Pronunciation gives two pronunciations:

Pronunciation (Received Pronunciation, General American) IPA(key): /ˈtsaɪtˌɡaɪst/, /ˈzaɪtˌɡaɪst/

https://www.merriam-webster.com/dictionary/zeitgeist also gives two: ˈtsīt-ˌgīst ˈzīt-

I tried to get statistics from listening to https://youglish.com/pronounce/zeitgeist/english? but found I have a hard time distinguishing the two forms.
