Festival issue :Cant hear the speech


I m having asterisk- on my CentOS system.
I m having festival installed on my system. I have also edited the festival.scm file as per the installation guide.

vim extensions.conf

[quote]exten => 555,1,Festival(‘Welcome to ABC Networks Private Limited’)
exten => 555,n,NoOp(===============================)
exten => 555,n,Festival(‘hello…how r u ? Good morning’)
exten => 555,n,NoOp(===============================)[/quote]


festival server working without having any error.

On the handset i hear no speech at all and the call hangs up? What could be the reason ?

I have used text2wav and its working fine. I can hear the speech properly. But cant hear with festival.


Any guess ?
