Here is a tar-file graph.tar for Linux. So, get a Linux. If you want to be sure that the programs run, install a twenty years old Red Hat Linux 6.1 to some PC or laptop and extract the files.
To extract files, create a directory with the name graph, copy graph.tar there and run
tar xfvz graph.tar
Then you have the subtitle timing tool in the subdirectory
graph/appl/subtitle_tool
You should watch the video
The program has the binaries and sources. If you do not want to install a so old Red Hat and the binaries do not run, delete object files and recompile by running make where there is one. If graphics does not start, go to graph/c/g1.c, locate initgraph() not the DOS version, and change the mode of X11. That should work, and yes, this is fairly old code. Look at the video to see how the menus work, they have my pre-1990 look and feel, you click left upper square with left mouse button to get the selected action done.
And one hint if you intend to run make, I hardcoded paths to the Makefiles, so the easiest for you is to make a user jorma and untar graph in his subdirectory graph, so all makefiles work.
About this Kennedy article, go to graph/appl/audiotool
There is only one program, y and one c-file y.c. Start y by ./y and the menus should explain all. The program can read audacity *.au files (those from the data directory) to text called *.res and it can change *.res to *.au. There are the *.au and *.res files for the Kennedy articles. You can make the actions in the menus, or write your own routine and replace e.g. my_correlation() in y.c. Nicely, you only need to look at y.c.
