<p>Factory method that is triggered by a call to <a href="qtexttospeech.html#QTextToSpeech">QTextToSpeech::QTextToSpeech</a>() when a provider name is given in the constructor and a text-to-speech plug-in matching the provider name was successfully loaded.</p>
<p>Value of <i>parameters</i> is currently always empty.</p>
<p>If an error occurs, the method should return 0 and (optionally) give a description of the error in <i>errorString</i>. In this case, <a href="qtexttospeech.html#state-prop">QTextToSpeech::state</a>() will return <a href="qtexttospeech.html#State-enum">QTextToSpeech::BackendError</a>.</p>
<p>If <i>parent</i> is 0, the caller takes the ownership of the returned engine instance.</p>
