    <title>Introduction to GNOME Speech</title>

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

    <title>Installation of GNOME Speech</title>

    <note>
      <para>You must install at least one of the backend drivers for
      <application>GNOME Speech</application> to render speech through the
      audio hardware. You should test the installation of the backend driver and
      ensure it produces desired results before installing
      <application>GNOME Speech</application>.</para>
    </note>

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

<screen><userinput>./configure --prefix=$(pkg-config --variable=prefix ORBit-2.0) &amp;&amp;
make</userinput></screen>

    <para>This package does not come with a test suite.</para>

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

<screen role='root'><userinput>make install &amp;&amp;
install -v -m644 -D doc/gnome-speech.html \
    $(pkg-config --variable=prefix \
    ORBit-2.0)/share/doc/gnome-speech-&gnome-speech-version;/gnome-speech.html</userinput></screen>

    <para><option>--with-jab-dir=$(pkg-config
    --variable=prefix ORBit-2.0)/share/jar</option>: Use this option if you
    have installed the <application>Java Access Bridge</application> package
    and wish to have <application>GNOME Speech</application> build
    in <application>Java</application> support.</para>

    <para>Note: see the <filename>README</filename> and
    <filename>INSTALL</filename> files in the package source tree for the
    correct parameters to pass to <command>configure</command> to enable the
    desired backends.</para>

  <sect2 role="testing">
    <title>Testing the Installation</title>

    <para>You can test all the available backend drivers, voices and audio
    hardware using the <command>test-speech</command> command. Invoking
    <command>test-speech</command> 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.</para>

    <para>If you are using the <application>FreeTTS</application> 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
    <systemitem class="username">root</systemitem> user, modify the
    <command>freetts-synthesis-driver</command> script:</para>

<screen role='root'><userinput>sed -i "s/clip/streaming/" <envar>$GNOME_PREFIX</envar>/bin/freetts-synthesis-driver</userinput></screen>
