I think it sounds feminine in a couple senses, but male in others:

* The speaker speaks less from the chest and more from the throat

* In terms of enunciation, females tend to speak more clearly on sounds such as "t"s, which can be observed here.

* The voice sounds a little more male in that the ends of many words trend lower in pitch, but more female in that they "bottom out" very early in the descent and dip heavily into vocal fry.

* There is less range of tone, which is more characteristically male.

All this aside, I wouldn't be surprised if it's actually multiple people. And I suppose the fact that we all disagree is evidence that they're doing something right. But I think most of us can agree it still sounds really wrong in some way.
