David,

You bring up a good point - how we actually sound to others is not 
necessarily how we perceive ourselves.
Here is the alternative that I use:
I have a good fidelity stereo system in the hamshack, and also have a 
recording of a male speaking voice (from a book on 'tape').  I play the 
recording on the stereo and hold the microphone close in front of the 
speaker while listening to the K2 on a separate receiver.   A talk radio 
program can also provide a source speaking voice.

The major drawback for this method is that just any sort of speaker will 
not do the job - if the speaker is not of above average quality, it will 
color its output and the microphone will receive a distorted sound.

I have also used this same method to evaluate various microphones for 
communications clarity.

73,
