So, we know that upon further meditation on Words of Power, the Dragonborn can unleash their hidden power in epic ways. He, however, can only use the Thu'um with certain words, as his normal voice is still mundane. So i ask you. After the subsequent quests, when you speak to a Greybeard, he answers with "Dovahkiin", rocking High Hrothgar like a thunder. Arngeir confirms that they cannot utter most words, as their voice would move skies and earth alike. But, as you can see from certain dragons, the dovah's dialogue does not include any fancy thundering effect. Instead, they use the more common Words of Power like the Dragonborn.

What's up? Can someone explain this?
