[CQ-Contest] SSB Voice Keying

[Peter Dougherty (W2IRT)]

I would like to see this as well. Last week I had some painful dental surgery which will absolutely preclude me from doing a serious effort in ARRL this week--I won't be able to run so just some DVK S&P is all I'll be able to muster. I would love to have a thoroughly integrated DVK speech synthesis module within N1MM+. I'd pay big bucks for it, in fact.

Very interesting, Rudy. I would love to see your work see the light of day just to see how much better it makes the experience.

Every automated text-to-voice transmission I have ever heard has sounded
kinda   s l o w  and I usually roll my eyes mentally every time I hear one.
 :-)

I totally get the convenience this feature brings to the casual op but if you're a serious competitor and using something like this, you're probably losing.

I've always considered one's voice a competitive advantage (or disadvantage, in some cases) - with these text-to-speech solutions all emotion and ability to customize responses is lost. Of course, one can always just key up and override it.
