Looks like it's a voice for orca and needs a license.
Extract and open the folder with install.sh.
Right click open terminal here.
this will start the script that will install the voice and the swift engine
to run the voice. The default location for the installation is /opt/swift,
but you can change this if you need. The script will test the installation,
but it is always a good idea to test the voice yourself. To do this, at the
command line (assuming you installed into /opt/swift/), type:
/opt/swift/bin/swift -n<name> "Hello world"
where<name> is the name of the voice you are testing. For instance, I
/opt/swift/bin/swift -n Callie "Hello world"
You should hear the voice say "Hello world". If not, you've got a problem
with the installation.
To register the voice (assuming you've purchased a license), type:
You will be prompted for information that you gave during the purchase as
well as for the voice name and the key that they sent you.
Once you have the voice working correctly, you need to install the
sudo apt-get install gnome-speech-swift
Once this has completed, you should be able to use the Orca
Preferences/Speech tab to change the speech server to the swift server and
configure the voice settings. If you do not find the swift speech server in
Orca Preferences, you need to edit (as root)the file /etc/ld.so.conf and add
at the end of the file. Once you have saved the file, as root, you need to
run ldconfig. This is described on the Orca wiki:http://live.gnome.org/Orca/GnomeSpeech
