The number of people saying that this voice sounds absolutely female is just an extension of the tendency to imagine anything even slightly deviating from the most stereotypically masculine as feminine by default. The one comment that I saw comparing this to a masculine voice was comparing it to a "gay flight attendant" that they had on a flight recently - and there, again, is the tendency to assume someone's gay just because they deviate slightly from the stereotypically masculine. The voice sounds genderless to me.
