Sounds like a project for a neural network. A bit of AI which
'recognizes' patterns. There would be ~ 40 outputs for letters,
numbers, and symbols. I am unsure of the number of inputs nor of the
middle layer(s) of the net. But that's just a bit of engineering.
The training sets would consist of a large set of "Lake Erie swing
music" and expert interpretations of it. Find a large computer and
spend a few weeks training the NN.
There are some shortcuts I foresee. Quite a few characters can't (?) be
messed up by the misuse of a bug. T, O, M, etc. Those don't really
need to go through the NN so you can save on the number of outputs and
decrease the training time significantly.
The neat things is once you've done all this work you can put the
trained NN into a very small space of code. And use a moderate number
of processor cycles.
Not quite DSP but AI is just another acronym :)

Might I suggest a filter that translates a bug user who sends at 15wpm, but
the dots are set to 35wpm. The filter would briefly store the cw, correct
the timing, and then pass it through the audio stages. Call it the
VibroDummy, or VD1 filter setting.
Another one would filter out the long "annnnd uuuuuhhhhh..." of VOX users
who only transmit 50% or less of transmit time as intelligible speech,
remove the non data periods, then pass the compressed version on. Call it
the VoxDummy, or VD2 filter.
Finally, introduce NR so sophisticated it automatically finds the correct
tuning soloution, requiring another 4 cu ft of room inside the K3 for
microprocessers and memory. Release it in a bloated, gigantic case, add 50
controls to the front panel, and call it a K4, thereby silencing two sets
of critics who post--but do not read--on the reflector.

Thanks for all the many great suggestions and digressions, folks. Sorry I
can't respond to all of them right away.
My favorite so far is the request for Semantic Filtering Mode (SFM), which
"might, with skillful adjustment, suppress political commentary from 75
meters." Our DSP IC does include odd/even partisan check bits, so this is a
SMOP.
Runner-up is a proposal for auto-detection of unattended FT8
transmissions, i.e. the "No One's Home AlarM" (NOHAM).
Feel free to pile on...
