I looked at it when you made your first post.
The first she-bang line was set wrong, it was an absolute path to the festival build directory instead if /usr/local/bin/festival
It still didn't work after I fixed that, I got some error from festival itself. Since I am not familiar with this program I wasn't able to fix it in a reasonable amount of time.

You can try asking the festival people, I suspect the number of people who have even a passing familiarity with festival on this forums are very few, if any at all.

The script had a copyright header from 1997. It may very well be an old relic that hasn't been working for years that nobody ever fixed or removed ...
