I work with audio signal processors such as the pitch shifter used in the audio clip we often hear of Majestic Ape talking about "special pizza" and "preferences". There is a distinctive sound that those devices make when a woman's voice is shifted down to sound like a man's, and I'm definitely hearing that here. The performer could be male or female, but the input to the pitch shifter must have sounded like a female to get this result. That's is to say, I as a male could use a pitch shifter to sound like the Majestic Ape voice, but I would need to affect a high pitched, feminine sounding voice to make that happen. If the input to the pitch shifter is someone's natural voice, it is most likely a woman.
