[CQ-Contest] Improving voice recordings for phone contests

[Joe]

Sounds pretty good.

The clarity and speed sound good.

I wonder what is still missing tho to sound better ummm like flow wise, 
where it has a better "Flow" and less choppy sounding? I wonder what 
would need to be done to get it to be more natural? each letter sounds 
good, now to get it to sound better flow wise ya know?

I wonder like the CW equivalent of shaping? Where the very beginning and 
end of the file has a fade in and out? very steep yes, but it is on CW 
too right? I wonder if that would help?

One of the problems I have always had is that when I try to enunciate clearly I always slow down, and the resulting recording lacks the urgency you expect in a contest situation. I also always notice stations whose recorded and live audio don't sound anything alike, and wanted to minimize that as much as possible.

The results are wonderful - you can speed up any recording 10 or 20 percent at a time, and it sounds completely natural, just faster.

Of course this can only happen if voice prompts are clear and easy to receive by the other station. The benefit is probably higher in a contest with a predictable exchange leaving only the call to constructed on the fly by N1MM.
