This unwanted effect is largely avoided by using a communications mic
correctly - speaking *across* the front of it, not into it. A boom mic that
will reach the front of your face should be positioned *below* your mouth.
Note that most newer boom mics stop short of the mouth. That automatically
ensures you won't talk into it.

While in college, I had a job for awhile at KPFA [FM] in Berkeley CA. 
They had one of those old RCA "velocity" mics [the sort of 
prismatic-shaped ones, fairly big] on the control board and one of my 
shifts was to sign the station on the air at 0600.  I discovered that, 
if I crawled right up to the mic while reading the sign-on script, I 
could sound like Johnny Cash instead of a 17 year old.  The effect was 
striking.  I think it's true of most mics, this one was just extreme...
