espeak’s apk doesn’t seem to have been updated in 2 years and says it isn’t compatible with my phone (Pixel 8a). I’m not sure if there are any decent ones. I want TTS for OSMAnd’s navigation while driving. They do prerecorded voices too but those can only say prerecorded things obviously, so eg can’t say specific road names.
Second recommendation for RHvoice, organic maps uses whatever your system tts is for its turn by turn verbal directions and I was curious if there was a good open source option, RH voice seemed decent in my time with it (switched phones and haven’t set things back up)
