Plus a new accessibility feature. The illiterate deaf who can read
lips would be able to use the XO. Upstream would greatly appreciate
At some point we could think about a matching cutaway view of the
vocal tract for language learners. I would love to see you animate the
Xhosa 'x' and 'q' clicks (See Miriam Makeba, The Click
Song/Qongqotwane), and all of the different 'rhotic' sounds (flap r as
in Japanese, trill as in Italian, hard retroflex as in southern New
Jersey, Boston, German gurgle, etc.).
"Izu zato 'aru' azu in Rondon, oru 'elu' azu in Loma?"
If you haven't heard the south Jersey dialect, I can't convey it to
you. You won't hear it on House MD, but you should.
"Pahk the cah in Hahvahd Yahd."
German, spoken, not sung. An uvular trill before a vowel. "Gr?n, alles
gr?n, so rings und rund."
Hey, wow, it's been done! Well, only the static positions on this
site, but presumably there is more elsewhere.
