I have a problem, like the title say I don't have the option in my voice setting "Download offline speech recognition". I decided to post it here because I don't find anything in internet after many hours, and I need this functionality for my application.
My device is an HTC Nexus 9 running Lollipop 5.1.1
You can see the problem on this screenshot.
