Synopsis:

    Provides a direct interface into the Cepstral
    text-to-speech engine for Asterisk eliminating
    the need to write audio output files to the 
    filesystem and then stream them back out.

    Also provides multi-digit dtmf recognition with
    a max digits and a wait-for-digit timer very 
    simular to the AGI 'get data' command.

Requirements:

    - Asterisk development header files
    - Cepstral Swift Text-to-Speech engine (version 5 or 6)

Installation:

    - Check that the swift libraries are in your ld path
      * on debian, run: echo -e "\n/opt/swift/lib\n" >> /etc/ld.so.conf && ldconfig
    - On some distributions you made need to copy asterisk.h to /usr/include

    ./configure [options]
    make
    make install (as root)
    make reload (as root)

Usage:

    Type "core show application swift" at the Asterisk CLI prompt.

    in extensions.conf:
    exten => s,1,Answer
    exten => s,n,Swift(This is cepstral talking in the default voice from swift.conf)
    exten => s,n,Set(SWIFT_VOICE=Callie-8kHz)
    exten => s,n,Swift(This is cepstral talking in the Callie voice)
    exten => s,n,Swift(Please enter three digits,5000,3)
    exten => s,n,Swift(You entered ${SWIFT_DTMF}.  Goodbye)
    exten => s,n,Hangup
