You will need to have Java installed. On OSX with Homebrew, do
$ brew cask install java
as needed.
On Debian-based Linux (including Ubuntu), do
$ sudo apt-get install default-jdk
accordingly.
To assemble, test, and package the voice for another MaryTTS installation, do
$ ./gradlew build
The packaged files will be placed under build/distributions.
Copy the zip file and xml descriptor into your MaryTTS installation's download directory, then run the marytts-component-installer to install the voice.
To build the voice and run it in an ad-hoc MaryTTS server, do
$ ./gradlew run
Then, go to http://localhost:59125.
