I was recently reading this article from the ARRL web site,

Morse Code at 140 WPM (ARRL)

about Chuck Adams, K7QO, who claims to be able to handle this speed all by himself. Very interesting article.

I would like to be able to copy above my natural speed, in order to get more familiar with how it sounds. My goal is to be able to get above the need to copy text but instead transition to simply listening to conversations like we do on SSB in voice.

The CW decoding software I have found is not all that reliable, though, with varying levels of accuracy.

So it occurred to me that I would like to find some way to have a computer help me copy CW in an "assist" mode - a combination of having the computer help me with text I copy on the keyboard, by maybe flagging letters and symbols where the computer and I disagree.

Neither purely me, nor purely the computer, but a combination of both.

Is there anything like this available?
