Theo,
You need to install a TTS engine:
https://grapheneos.org/usage#accessibility
recommends eSpeak NG or RHVoice. They're available from the Play Store
or F-Droid.
As luck will have it I somehow entered the right keywords into the websearch and found that webpage too.
Alas, I downloaded and tried both, but neither wished to work. Why ? I do
not have the foggiest. :-(
I also found this webpage :
https://github.com/GrapheneOS/os-issue-tracker/issues/377 , but even explicitily selecting the (single) TTS engine didn't allow my eBook reader
to connect to the TTS component - nor did the eSpeak NG's internal "say what you write her out loud" test work. No failure messages though. Just .. nothing.
Also, the eSpeak NG one (that I just downloaded) was frowned upon (got
multiple warnings) because it was 32 bit ...
Regards,
Rudy Wieser
