Ah, that...  This has a simple solution.

You need to quote the whole command, like so:

  (concat "\"stty -echo ; " cmd "\"")

(Btw, if you want to invoke a shell command, why do you use
start-process?  Why not use shell-command instead (if the command ends
with a "&", it will be run asynchronously)?

I don't know what is "gp" and how does it invoke Emacs.
