Hi Trevor, thanks for that.

This is an interesting programme, particularly for those without on-board 
processing,  but I was hoping there was a way of evaluating a processed 
speech pattern without having to listen to it, ie completely objectively. 
Let's say I have a defect in my hearing (who doesn't have something lacking 
at "our" age?) how do I know that I have optimised my own transmitter for my 
own voice?  Listening to my own voice is fraught with variabilities, I might 
just have a head cold that day or wax in my ears and apply too much boost to 
the hf end, for instance.

The Vshaper is good for showing the spectrum, but speech intelligibility is 
not discernable from that spectrum.

If you have the ARRL Handbook for 1988, the first page of Chapter 7 gives 
clues but not enough to go on for me.
