[Xastir] R PI Xastir Festival and greyed out box

[Stephen black]

I am using Rasbian from NOOBS. Xastir is running OK and Festival server 
is too. I loaded the sound files to get Audio alarms working and they 
do. When I open  configure then speech the choices are greyed out. I am 
a new Linux user and have searched the web for a fix to no avail. I have 
a real need to have the text to speech feature working. Thanks Steve KB1CHU
