How to change the language of LG's voice notifications?

A

AC Question

New LG G4. In my settings I changed the overall language to Russian. I also changed the Google TTS Engine language to Russian as well as downloaded the appropriate voice pack. The sample phrase clearly speaks Russian, and all text on my phone is in Russian.

Except...
When I get a text or call, my phone still speaks English just using a Russian accent. I want it to speak actual Russian, can it do this?

I'm coming from an HTC that didn't give voice notifications, is this an LG-specific feature? Can the voice notification language be changed, or does it just simply give it a slight accent?
