I think one problem with this is that we tend to end an utterance on a
downward intonation. I wonder if the voicing might be improved to
include initial, mid-phrase and end intonations. Short of that the only
thing I can suggest is to trim your letters and numbers really closely.
Audacity lets you zoom in and get the last millisecond of dead air.

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?

Before last weekend's contest, I had a chance to experiment a bit
with my voice recordings. 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.
I use Audacity, excellent freeware recording software, but this time
around I "discovered" its "Change Tempo" function, which speeds up
speech without changing the pitch or timbre. The results are
wonderful - you can speed up any recording 10 or 20 percent at a
time, and it sounds completely natural, just faster.
*listen and adjust the tempo (on the same Enhance menu) for the
effect I want. Repeat these 4 steps for each recorded message.
I used the same methodology for the recordings I made for CQ160 SSB
where I had to go "silent". I voiced in normal speed (or slightly
below normal), articulating clearly and used about 20-30% tempo
increase. I would be interested to hear others "best practice" on the
amount of speed increase.
A sample exchange of mine is posted on the SE0X blog, go to
www.se0x.info in the CQ160 SSB update and listen to the audio file.
Another benefit of voicing all prompts is that exchanges are kept to
the essentials keeping the rate high. 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.
