All mortal races are capable of using the Voice, not just the Nords, but only the Greybeards still practice it. The Dragonborn has an innate ability to produce a Thu'um, and doesn't actually know how they do it, they just do. The Dragonborn would not be able to teach others to use the Voice because they don't know how it works. The only others that know how to use the Voice are Ulfric and the Ebony Warrior (who could both be dead btw). Even so EW only knows Unrelenting Force and I think Ulfric also knows Disarm. So Ulfric would be able to teach a grand total of two shouts with several years of training. Fan-fucking-tastic. That leaves only the Greybeards, and good luck trying to get the Greybeards to help you after telling them you're going to ban their religion.

But then again, there is always the Draugr. You could try asking them for help.
