I said woman's voice based on a few factors, The Main being in Jungian Psychology the Anima is the Female aspect of the subconscious where as the Animus is the male.

Another is that the Dragoon Spear, The Rhongomynyad, is the legendary Lance of King Arthur and was (most likly) granted to him by The Lady of the Lake along with his sword, Excalibur, and his dagger,Carnwennan.

So personally for me Rhongomynyad has the spirit of The Lady of the Lake in it. (The Lady of Silvertear Lake specifically since the glow on the i200 form of the spear is simmilar to the energy we channel from midguardsormr via Blood of the Dragon and The Dragonsong Dive)
