To use the good offline map app Here Wego, you need TTS. I downloaded it successfully via Aurora, but I can't add any language for offline use. This means that Here Wego generally doesn't work with voice, not even online.
I've read many posts, including in this forum, but none of them had a satisfactory solution. RHVoice, for example, has no German language available. Other apps are obviously very outdated and buggy. I downloaded an older version of Google TTS via APKpure, but it wouldn't install at all.
I read somewhere that it is absurd to "reinvent the wheel" when there is already a good solution - with Google. Unfortunately, this is not yet included by default in GrapheneOS.
In short: I need this function and would like a good solution with voices that I like to listen to when the navigation system accompanies me on the roads.
Does this solution exist?
PS: Apart from that, I am largely satisfied with GrapheneOS. The installation went well. And the issue of voice quality when making calls still needs to be addressed. An esim-card delivers choppy, hard-to-understand speech to the other person.
