I am sure there are a number of people who will agree and disagree
regarding the term "air speed". However, it is a core concept to my
teaching and playing, and, while me may not agree on exactly what air
speed is and how it is defined, what I refer to as air speek in my playing
and teaching has to do with actual speed of air - not air pressure.

Visualize an air compressor, or better yet, a water hose. Depending on
the appature (and can't that mean every thing leading up to the final
hole??) size, pressure is a constant. I believe that the back of our
throat contains within it a valve called the tongue, which is capable of
controlling not only register changes on the clarinet but speed of air
that gets to the eventual appature (lips/mouthpiece). The tongue
placement affects the speed of the air (pressure is constant) and can
impact on tone color, volume, and pitch.

Ok.....so....let's get some other opinions going on this one.....

I hope this clarifies what I meant by air speed.
