I'm not going to get into this, but changing the oral cavity can only result in a change of pitch from within the same note that is being caused from lip vibration. So if you play a high C and change the oral cavity, the pitch will change within the range of that note. The only other vibrating membrane would be the vocal chords, if that is what you're doing. You are then seperating "diggery-doo" like sounds and not actual pitches caused from humming notes, i.e., multiphonics. You cannot create a pitch through vibration if there is nothing left anatomically to vibrate. Even if you are producing "diggery-doo" sounds, that is considered multiphonic. In which case still only leaves you with 2 vibrating sets of tissue.
