I don&#x27;t know where the research on this would be, but I suspect this sort of thing is about exploiting an ingrained cultural association from leaders reading prepared speeches&#x2F;sermons. No filler words =&gt; commanding&#x2F;authoritative&#x2F;confident&#x2F;powerful.<p>I agree that it would probably get tiresome very quickly in regular conversation. It reminds me of a comedian who asked &quot;Do you think Jesse Jackson talks like that at the dinner table?&quot;, referring to the &quot;Baptist preacher voice&quot; seemingly being Jackson&#x27;s default voice when he&#x27;s interviewed on TV&#x2F;radio.
