[Asterisk-Users] Asterisk and Festival (* dies with no info)

[Iain Stevenson]

It may not be you, I think the Festival driver is buggy.  Specifically, 
I've found that the the way in which you pass the text to Festival matters. 
If I use the Festival () suntax then it won't work.  If I use the wrong 
sort of quotation mark " instead of ' there are problems.  Asterisk will 
consume vast amounts of processor resources.

However, if I specify the command in a way the Festival app likes then all 
is OK.  Try variants like:

exten => 555,4,Festival,'mary had a little lamb'
