You can save a copy of the current file in continuous.c.old so that you can always get back to the starting program, if required. Then, you will need to edit the continuous.c file. It is very long and a bit complicated, but you are specifically looking for the section in the code, which is shown in the following screenshot. Look for the /* Exit if the first word spoken was GOODBYE */ comment line:

In this section of the code, the word has already been decoded and is held...
