That tells something about the poor educators.

that sounds cool. here's the abstract (which I paste here because there's some neat words in it!) The development of supraglottal flow structures during speech1 BYRON ERATH, Purdue University, MICHAEL PLESNIAK, George Washington University —
During voiced speech, periodic vocal fold oscillations create a pulsatile jet that emanates from the glottis and is convected through the supraglottal tract. Unsteadiness in the supraglottal jet trajectory (superior to the vocal folds) has been observed in a variety of laryngeal flow investigations, contributing to sound production due to vortex pairing which occurs within the jet as well as the impingement of the deflected jet on physiological structures. However, there is confusion in the literature concerning the mechanisms which contribute to the flow variability. Instabilities in the supraglottal jet include the Kelvin-Helmholtz instability, as well as the hypothesized presence of jet ’flip-flopping’, the tendency of the glottal jet to detach from one vocal fold wall and reattach to the opposing wall mid-cycle. The morphology of the supraglottal flow field is investigated using phase-averaged PIV measurements acquired in the anterior-posterior midplane of the superior vocal fold tract of a dynamically controlled 7.5 time life-size vocal fold model. Flow parameters are scaled to match physiological values. The relevant fluid flow phenomena that impact the supraglottal jet trajectory are identified. (emphasis added) pulsatile. fun. fluid dynamics is just really nifty.

Funny. A Space Odyssey of the voice?

Pretty neat. I've have sometimes toyed with the idea of developing a truely alien language, say one with a weird phonology based on a non-humanoid vocal tract (e.g., a forked throat). It's not just the glottis that comes into play with phones. The glottis is buzzed for voiced sounds as opposed to voiceless, but it does something else for creaky voice sounds, and it is shut and dropped, elongating the vocal tract, for glottalized or ejective sounds. The fluid dynamics take on phonology would be interesting indeed. The difference between momentarily stopping the flow of air at certain places (e.g., lips, palate, velum)rather than just contricting it (for fricatives). Also the nasal cavity comes into play when stopping the flow, but opening up the nose for the escape of sound.

sorta like the Bushmen of the Kalahari and their clicks, etc?

Yes. The funny thing about clicks is that we have some in English, but they are not used in words. Just sounds you make when air kissing or urging a horse to start walking.

I'm enamored with the "physics-based" approach they took. It's helpful for people to converse about the thing and it might motivate additional questions.

For folks who would like to experiment, you can use Audacity ( link) or from the Netherlands Praat ( link).
