I created pages for both espeak-ng and speak-ng, but they basically function the same. I did not create an alias page since they aren't symlinks to one another, and seems to vary in filesize.

❯ ls -l $(which speak-ng)
-rwxr-xr-x. 1 root root 498240 Oct  6 08:00 /usr/bin/speak-ng*

❯ ls -l $(which espeak-ng)
-rwxr-xr-x. 1 root root 24832 Oct  6 08:00 /usr/bin/espeak-ng*

They also have a separate documentation page for each, but both are similar (speak-ng documentation is older by 2 years than espeak-ng documentation).

Thoughts?

I think it's ok to have them be separate pages. In case one diverges from the other in syntax.
