I don't. That is one of the reasons I used the quotes around the word
"Added". I believe that most of the time it is involuntary although I
have noted in some recent posts at least one individual that does it
purposefully and others that have observed that a favorite singer's use
of this might give them the sense that it is ok to try.

What I was observing was that in some singers the effect doesn't
manifest itself all of the time. In some it appears only when the voice
is under increased load.
