it would depend on how you mean it, the reason the dragonborn or odhaving come is because you challenged called them, as they said about dragonrend, you have to take it into you, it becomes a part of you, you would have to mean it the way you you want it to work. if you want to push stuff away you'd have to say it like you want to push stuff away, but if you're calling a dragon named Fusrodah you would probably have to know that such dragon exists, then call out to him while using the voice.
