So far I'm unable to get this to work. When I go to text-to-speech output, I choose RHVoice for preferred engine. Language is set to 'Use system Language'. If I change it to one of the two languages I downloaded (English US and English Russian) the settings app crashes. If I leave that setting alone, I can't change speech rate or pitch, its disabled. Is that normal?
I did the talkback tutorial briefly before exiting.
The option in Organic maps is still disabled for turning on voice instructions.
Any ideas on what I can try?
