There's one more thing you can do. Settings / general management /language and input /turn on keyboard button. When you open the keyboard an icon on the right side of the navigation bar will open a pop-up menu that lets you select between Google voice typing and Samsung voice input. If you have 2 keywords installed you can switch between them. I'm using SwiftKey as the default and it uses Google voice typing as the default for voice to text. It's nice to be able to use both voice inputs and keyboards to see which one is more accurate.
