Rooting hp slate 7 voicetab ultra

I wanted to root my tablet, which is HP Slate 7 Voicetab Ultra, but it wasn't on the list, and they suggested to take a look at the forums. I couldn't find it here either... Does anyone know how to root this or am i the only user of this tablet in the world? My android version is 4.4.2.
Thanks!

IF the date of the kernel (in About Device) is June 2, 2014 or earlier, Towel Root will root it. If it's later, there's probably no root method for it.
