    <title>Introduction to FreeTTS</title>

    <para>The <application>FreeTTS</application> package contains a speech
    synthesis system written entirely in the <application>Java</application>
    programming language. It is based upon
    <ulink url="http://www.cmuflite.org/">Flite</ulink>: a small run-time
    speech synthesis engine developed at Carnegie Mellon University.
    <application>Flite</application> is derived from the
    <ulink url="http://www.cstr.ed.ac.uk/projects/festival/">Festival</ulink>
    Speech Synthesis System from the University of Edinburgh and the
    <ulink url ="http://festvox.org/">FestVox</ulink> project from Carnegie
    Mellon University. The <application>FreeTTS</application> package is used
    to convert text to audible speech through the system audio hardware.</para>

    <title>Installation of FreeTTS</title>

    <para>The <application>FreeTTS</application> package is distributed in
    ZIP format and the <command>unzip</command> command will default to
    creating an unused source directory. Additionally,
    unzipping the test suite file will prompt for questions
    about overwriting existing files. Use the following commands to
    <command>unzip</command> the source files:</para>

<screen><userinput>unzip -q freetts-&freetts-version;-src.zip -x META-INF/* &amp;&amp;
unzip -q freetts-&freetts-version;-tst.zip -x META-INF/*</userinput></screen>

    <tip>
      <para>The <command>sh jsapi.sh</command> command below installs the Java
      Speech API components into the <application>FreeTTS</application> source
      tree. You will be required to view, and then accept (by entering a
      <keycap>y</keycap> keypress), a license agreement before the installation
      will continue. If you are scripting (automating) the build, you'll need
      to account for this. There is information about automating build commands
      in the <xref linkend="automating-builds"/> section of Chapter 2. Towards
      the end of this section, specific information for automating this type of
      installation is discussed.</para>
    </tip>

    <para>Install <application>FreeTTS</application> by running the following
    commands:</para>

<screen><userinput>sed -i 's/value="src/value="./' build.xml &amp;&amp;
cd lib      &amp;&amp;
sh jsapi.sh &amp;&amp;
cd ..       &amp;&amp;
ant</userinput></screen>

    <para>To test the results, issue:</para>

<screen><userinput>ant junit &amp;&amp;
cd tests &amp;&amp;
sh regression.sh &amp;&amp;
cd ..</userinput></screen>

    <para>Now, as the <systemitem class="username">root</systemitem> user:</para>

    <para>Optionally, install any or all of the additional

    (see the Command Explanations section for details):</para>
