It looks like the code in part.cpp is starting KTTSD in order to determine if the \
context menu item should be enabled/displayed or not.  Instead of starting KTTSD, \
which is something user might not want, you could detect if KTTSD is available \
something like this:

    // If KTTSD is not installed, hide action.
    KTrader::OfferList offers = KTrader::self()->query("DCOP/Text-to-Speech", "Name \
== 'KTTSD'");  if (offers.count() > 0)
        // Enable context menu option.
    else
        // Disable context menu option.

Then if user chooses to speak text, start KTTSD if needed.

Note: You may have to insert a delay after starting KTTSD before sending it text to \
speak.  I have some code like this in kdebase/konqueror/kttsplugin/khtmlkttsd.cpp to \
deal with this:

void KHTMLPluginKTTSD::slotReadOut()
{
    DCOPClient *client = kapp->dcopClient();

    // If KTTSD not running, start it.
    if (!client->isApplicationRegistered("kttsd"))
    {
        QString error;
        if (kapp->startServiceByName("KTTSD", QStringList(), &error))
            QMessageBox::warning(0, i18n( "Starting KTTSD Failed"), error );
        else
        {
            // Give KTTSD time to load.
            QTimer::singleShot(1000, this, SLOT(slotReadOut()));
                return;
        }
    }

This may or may not be needed.  I'm not sure.
