Install Cepstral on PIAF server

• Note: Cannot run Make in swift app until Cepstral voice is installed. Dependency.

Grab Swift

cd /usr/local/src
git clone https://github.com/awayment/app_swift

Grab Voice

uname -a

• NOTE* Always be sure you download x86-64 for 64 bit machines and i386 for 32 bit!! uname -a will show i386 or x86_64
• change the voice to the one purchased
• Note David vs Allison 64 vs 32 bit.
• PIAF comes in both flavors.
• Voices come in both flavors.
• Installers come in both flavors!
• Verify actual file locations by downloading to your own workstation and edit the wget line accordingly

cd /usr/local/src
wget http://www.cepstral.com/downloads/installers/linux64/Cepstral_Allison-8kHz_x86-64-linux_6.0.1.tar.gz
wget http://www.cepstral.com/downloads/installers/linux32/Cepstral_David-8kHz_i386-linux_6.0.1.tar.gz
tar -xvzf Cepstral_Allison-8kHz_x86-64-linux_6.0.1.tar.gz
cd Cepstral_Allison-8kHz_x86-64-linux_6.0.1

Testing the installed swift binary...
/opt/swift/bin/swift -o /dev/null 'hello world'
/opt/swift/bin/swift: line 12: /opt/swift/bin/swift.bin: cannot execute binary file
/opt/swift/bin/swift: line 12: /opt/swift/bin/swift.bin: Success

• cannot execute binary file = you installed for the wrong processor (32 bit vs 64 bit) most likely.

When you do succeed:

/opt/swift/bin/swift -o /dev/null 'hello world'

Install swift

cd /usr/local/src/app_swift/Asterisk_1.8
make
make install

result

if ! [ -f /etc/asterisk/swift.conf ]; then \
                install -m 644 swift.conf.sample /etc/asterisk/swift.conf ; \
        fi
if [ -f app_swift.so ]; then \
                install -m 755 app_swift.so /usr/lib/asterisk/modules ; \
        fi

Not very verbose, but that's a successful install of swift. Continue

Asterisk

echo "/opt/swift/lib" > /etc/ld.so.conf.d/swift.conf; ldconfig
asterisk -rx "core restart now"
asterisk -rx "core show application swift"

Success:

Register Voice

Dialplan entries

nano extensions_custom.conf

Add at bottom:

[swift]
exten =>_X.,1,NoOp()
same =>n,Set(foo=${CURL(http://ip.whowebwhere.com/TTSTest.php?cepstral=output)})
same =>n,swift(${foo})
same =>n,wait(2)
same =>n,swift(${foo})
same =>n,wait(2)
same =>n,swift(${foo})
same =>n, Hangup()

Fix voice name!

• If you have issues, check this file for the voice you licensed/downloaded

cd /usr/local/src/app_swift
emacs swift.conf.example
replace "voice=Allison-8kHz" with "voice=David-8kHz"
cp swift.conf.example /etc/asterisk/swift.conf

Final

Generate a dialplan entry that will dial a number at the swift context. Generally this is done by creating a sip phone or carrier with "context=swift". Then that sip accounts "dials" will execute in the swift context. (Have to convert our local notes for this, coming momentarily).

Next we need to add the data to a table on vicidial's side and add the acquisition of the data from that table with Cepstral to generate the TTS. (Have to convert our local notes for this as well, coming momentarily).
