Fox News political analyst Brit Hume says Democratic presidential nominee Hillary ClintonHillary Diane Rodham ClintonOvernight Defense: Trump declares border emergency | .6B in military construction funds to be used for wall | Trump believes Obama would have started war with North Korea | Pentagon delivers aid for Venezuelan migrants Sarah Sanders says she was interviewed by Mueller's office Trump: I believe Obama would have gone to war with North Korea MORE had a "lecturing tone" with a "not-so-attractive" voice during her acceptance speech Thursday night in Philadelphia.

The one-time ABC chief White House correspondent was generally positive about Clinton's speech but also opined that her efforts "to make herself more appealing to the audience might not have done as well."

"She has a habit, when speaking, of breaking into kind of a sharp, lecturing tone," said Hume on Fox during the network's post-speech coverage. "It makes you feel a little bit like you’ve been called into the principal’s office to be read the riot act." 

Hume went on to say that Clinton "has a great asset as a public person, which is a radiant smile, but she has a not-so-attractive voice.”

The analysis echoes a similar perspective shared on MSNBC earlier this year. 

“One of the trickier things to teach people about public speaking is that the microphone works, you don’t have to actually yell,” MSNBC’s Lawrence O’Donnell said on an edition of "Hardball with Chris Matthews." “There’s a private version of Hillary Clinton that’s very winning and very charming, that’s because there’s no microphone.”

“When you’re going up every octave with every word, people are like, 'I have to get some popcorn and get away from this,'” former Republican National Committee chair and MSNBC contributor Michael Steele added during the same segment. “You’d think after all the years, she would figure that out.”
