Text To Speech Integration
Cepstral + Asterisk
I've now realized that due to extremely busy schedule at job and home I may not get any extra time to make a sample story; insert it into the MySQL DB; make a dialplan for it; create its web end to manage/edit stories and present it here. So instead of delivering it all in one piece its better to take a start from giving our Asterisk server a voice by installing Cepstral TTS engine.
Following are the commands to get going.
Download and Install Cepstral TTS Engine.
#wget http://downloads.cepstral.com/cepstral/i386-linux/Cepstral_Callie-8kHz_i386-linux_5.1.0.tar.gz #tar zxvf Cepstral_Callie-8kHz_i386-linux_5.1.0.tar.gz #cd Cepstral_Callie-8kHz_i386-linux_5.1.0 #./install.sh
Download and Install App-Swift.
App_swift is the connector between the asterisk and Cepstral engine.Swift runs from inside asterisk as an application and uses the Cepstral TTS engine running in Linux.
#cd /usr/src/ #wget http://pbxinaflash.net/source/app_swift/app_swift-1.6.2.tar.gz #tar zxvf app_swift-1.6.2.tar.gz #cd app_swift-1.6.2/ #make #make installIssue this command to let Cepstral recognize the Swift module and let it use its engine.
#echo /opt/swift/lib > /etc/ld.so.conf.d/cepstral.conf #ldconfig
Thats it and now your TTS engine and Asterisk app_Swift connector should be ready to rockTest Asterisk for Swift Application.
Now test Asterisk for swift application; On CLI execute the following command
Asterisk*CLI>core show application swift
You should get some long output like below:
-= Info about application 'Swift' =-[Synopsis]
Speak text through Swift text-to-speech engine.

same => n,Swift(Hello World This is an Asterisk server)
same => n,NoOp(Key pressed: ${SWIFT_DTMF})
same => n,Swift(You pressed ${SWIFT_DTMF}. Goodbye.)
same => n,Hangup()
exten => h,1,Hangup()
Thats all, now make your own dialplan and enjoy talking to your asterisk server. Best thing for Forever Alone guys ;)
