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("ÎÏ
ÏÏ ÎµÎ¯Î½Î±Î¹ Îνα αÏλÏ
ÏÎÏÏ ÏοÏ
espeak ÏÏα 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()
