The GNOME Speech package provides a simple general API for producing text-to-speech output. Multiple backends are supported by the GNOME Speech library, but currently only the Festival backend is built by default; the other backends require either Java or proprietary software.

You must install at least one of the backend drivers for GNOME Speech to render speech through the audio hardware. You should test the installation of the backend driver and ensure it produces desired results before installing GNOME Speech.
Install GNOME Speech by running the following commands:
./configure --prefix=$(pkg-config --variable=prefix ORBit-2.0) && make
This package does not come with a test suite.
Now, as the root user:
make install && install -v -m644 -D doc/gnome-speech.html \ $(pkg-config --variable=prefix \ ORBit-2.0)/share/doc/gnome-speech-0.4.2/gnome-speech.html
--prefix=$(pkg-config --variable=prefix ORBit-2.0): Setting the prefix using this parameter instead of with $GNOME_PREFIX will ensure that the prefix is consistent with the installation environment and the package will be installed in the correct location.
--with-jab-dir=$(pkg-config --variable=prefix ORBit-2.0)/share/jar: Use this option if you have installed the Java Access Bridge package and wish to have GNOME Speech build in Java support.
Note: see the README and INSTALL files in the package source tree for the correct parameters to pass to configure to enable the desired backends.
You can test all the available backend drivers, voices and audio hardware using the test-speech command. Invoking test-speech produces a menu allowing you to select a backend driver and the desired voice, then prompts you (with on-screen prompts and text-to-speech audio) for additional information.
If you are using the FreeTTS backend and you do not hear any audio, you may need to use the streaming audio method instead of the clip audio method. As the root user, modify the freetts-synthesis-driver script:
sed -i "s/clip/streaming/" $GNOME_PREFIX/bin/freetts-synthesis-driver
