This editor is not production ready yet! For latest development news look at commits. For production purposes you can use older snapshot of espeak-ng-editor!

Building

Building espeak-ng (optional)

There library built in this project already, which is located in lib folder. Following is description how to build library from eSpeakNG source files:

eSpeakNG Java Editor relies on libraries of eSpeakNG, which have to be recompiled with custom settings. Clone eSpeakNG project and solve dependencies:

(To be sure) install additional packages:

sudo apt-get install libwxgtk3.0 libportaudio2 sox libwxgtk3.0-dev libportaudio-dev

You need to install Mbrola to see Prosody tab, use this command:

sudo apt install mbrola mbrola-en1

When invoke building of espeak-ng project add additional -fPIC flags to compiler, e.g. by compiling in following way:

./autogen.sh
CFLAGS='-fPIC' ./configure --prefix=/usr
make -B

espeak-ng-jeditor

Clone espeak-ng-jeditor project. Note that espeak-ng and espeak-ng-jeditor projects should be subfolders of common folder!

Compile customized shared library by executing Bash script in espeak-ng-jeditor project folder:

./updateJNIchanges.sh

To rebuild Java classes, run Maven task:

mvn compile

Running

  • In IDE: select MainWindow.java class in org.espeakng.jeditor.gui package and run it as Java application.
  • In terminal ececute command: java -cp target/classes org.espeakng.jeditor.gui.MainWindow

Packaging

  • To package editor in single *.jar file, execute command:
mvn clean compile assembly:single
  • Then run archive located in target folder, by executing command:
java -jar eSpeakNG-jEditor.jar

(Note that libespeakservice.so file is copied to ../.lib folder from *.jar file for execution.)
