The first resonance frequency is lowered to around 200 Hz, which means that the lower-frequency harmonics can benefit from vocal tract acoustic inertance in a range from 200-1500 Hz.
Vocal Tract and Glottal Function During and After Vocal Exercising with Resonance Tube and Straw.
Not a challenge, as the biometric picks up the voice print from the various factors of the voice, nasal passage, vocal tract, and combinations of physical and behavioural characteristics, and has no bearing on language spoken.
This gave them a map of which parts of the brain control which parts of the vocal tract.
Magnetic resonance imaging (MRI) is a widely used tool to acquire three dimensional (3D) anatomic data of the vocal tract (VT) for speech production studies, simulation and articulatory synthesis (Hannukainen, Lukkari, Malinen, Palo 2007; Stone, Stock, Bunin, Kumar, Epstein, Kambhamettu, Li, Parthasarathy, Prince 2007; Svancara, Horacek 2006).
The problem is that our lack of knowledge about the fine articulatory details of speech production and the inherent complexity of creating an accurate mechanical model of the vocal tract inevitably give rise to a computationally expensive and still crude approximation of human speech.

They investigate the effect of the lowering of the larynx in humans, comparing the areas of acoustic space in male and female vocal tracts, and the implications of such data for modelling the evolution of speech.
Furthermore, the vocal tract in living mammals is quite flexible, and a resting position different from the human configuration does not preclude a dynamically lowered larynx, giving near-human vocal capabilities, during vocalizations (Fitch, 2009).
However speaker recognition accuracy using pitch is low compared to features of the vocal tract [2].
