[asterisk-users] espeak app for asterisk 1.6

[Lefteris Zafiris]

I have written a module for asterisk that uses the eSpeak
speech synthesizer (http://espeak.sourceforge.net/) to
render text to speech. The source is available here:
http://zaf.github.com/Asterisk-eSpeak/
It's similar to app_festival and app_flite.
It's only tested against asterisk 1.6.1 on x86 Linux but it must be
working for other 1.6 branches too. Comments, fixes and suggestion are
welcome.



===========================================
         Espeak For Asterisk 1.6
===========================================

This provides the "Espeak" dialplan application, which allows you to use
the Espeak speech synthesizer with Asterisk. This module invokes the Espeak TTS 
engine
locally, and uses it to render text to speech.

------------
Requirements
------------
Asterisk 1.6 header files
Espeak libraries and header files
        **It is recommended to use espeak version 1.41.01 or newer.
        Earlier version of epseak had an file descriptor leak that could 
        cause asterisk to crash. If upgrading is not an option patch your 
current 
        version of epseak with the espeak.patch provided here.
libsndfile libraries and header files
libresample libraries and header files


------------
Installation
------------
$ make
$ make install

To install the sample configuration file, issue the following command after
the 'make install' command:

$ make samples

-----
Usage
-----
Espeak(text[,intkeys,language]):  This will invoke the eSpeak TTS engine,
send a text string, get back the resulting waveform and play it to
the user, allowing any given interrupt keys to immediately terminate
and return.

--------  
Examples
--------
dialplan sample code for your extensions.conf
  
;Espeak Demo
                exten => 1234,1,Answer()
                        ;;Play mesage using default language as set in 
espeak.conf
                exten => 1234,n,Espeak("This is a simple espeak test in 
english.",any,)
                        ;;Play message in Spanish
                exten => 1234,n,Espeak("Esta es una simple prueba espeak en 
español.",any,es)
                        ;;Play message in Greek
                exten => 1234,n,Espeak("Αυτό είναι ένα απλό 
τέστ του espeak στα ελληνικά.",any,el)
                        ;;Read a text file from disk (relative to the channel 
language)
                        ;;and play it with espeak using the asterisk channel 
language.
                exten => 1234,n,ReadFile(MYTEXT=/path/${LANGUAGE}/myfile,200)
                exten => 1234,n,Espeak("${MYTEXY}",any,${LANGUAGE})
                exten => 1234,n,Hangup()
