A membrane produces the manner of articulation (soundwaves), that will need some sort of resonating device, which may or might mimick the bilabial, labiodental, dental, alveolar, postalveolar, retroflex, palatal, velar, uvular, pharyngeal, epiglottal and glottal articular shapes. The articulary shapes might be fixed devices or use some kind of flaps/automodeling to respond differently responding to pressure/volition, but anyhow they will be simplifications/modifications from the actual biological device they are inspired by.
These articulators are atoms in a new non-biological species, they need not copy, only let themselves be inspired by successful designs in nature.
