Intriguing... do tell? From the UESP: Alduin has a dragon shout named "Dragon Storm Call". It is similar to Storm Call, but it calls forth a meteor storm instead of a lightning storm and the sky turns red instead of stormy grey. Clear Skies has been known to cause it to end prematurely. Alduin has another shout called "ResurrectionShout" that resurrects dead dragons. The dragon soul will rebuild the dragon's Body. Its words of power are 'Slen Tiid Vo'. Its translation is Flesh Time (Opposite of). It should be noted that player can learn the words Tiid (Time) and Slen (Flesh), showing that words can be part of different shouts. The soul-snare mist created by Alduin in Sovngarde is technically not a dragon shout, but a script. It creates a mist where Alduin hides and feeds upon the trapped souls. Its words of power are 'Ven Mul Riik', which translate to 'Wind Strong Gale'. The shout used by Tsun to send the player back to Nirn from Sovngarde is another unavailable shout. Its words of power are Nahl Daal Vus; its translation is 'Living Return Nirn'. The shouts used by dragons are different versions of the shouts used by the player and NPCs. There is also a shout that the Greybeards use to create ethereal target practice dummies for your shout practice. It is Fiik Lo Sah, which is translated as 'Mirror Deceive Phantom'. It is another shout unavailable to you. However, it can be unlocked using the console command psb. The shout was apparently intended to be usable by the player, as it is voiced for all races. During the learning of Whirlwind Sprint, one of the Greybeards (Borri) opens the gate doors using a shout called "Bex", meaning "open". This is also a shout unavailable to the player. Dawnguard adds Soul Cairn Summon, a shout unique to Durnehviir. Its Words of Power are Diil (Undead), Qoth (Tomb) and Zaam (Slave). Each word summons an undead minion from the Soul Cairn; the full shout will summon a Wrathman, Boneman and Mistman to aid Durnehviir in combat. Most of these could be used in gameplay.
