+    <p>When using the Narrator function, most AI models should be using asterisks or double quotes to differentiate between the Narrator or the Character, however, many models sometimes switch between using asterisks and double quotes or nothing at all. This leaves a bit of a mess because sometimes that text is narration and sometimes its the character talking and there's no clear way to know where to split sentences. There is no 100&percnt; solution at the moment.</p>
+    <p>Most models usually lean more way than the other as to it is narration or the character talking when it does this. So you can use the "<b>Text NOT inside of * or &quot; is</b>" function to decide what the TTS engine should do in situations like this. It's an either/or situation. It will either use the Character voice or the narrator voice when text is not inside asterisks or double quotes.</p>
