Even with very different messages, politicians ###### sound the same, new research finds. ###### who analyzed the vocal stylings of ###### presidential contenders in the 2016 race - Hillary Clinton, Carly Fiorina, Bernie Sanders ###### Donald Trump - found that all ###### candidates altered their voices in similar ######, depending on the audience.

The findings, ###### at the Acoustical Society of America ###### in Salt Lake City, Utah, offer ###### insight into the vocal strategies of ###### speakers.]]>
When it comes ###### politics, it's not what you say, ###### how you say it. There's a ###### reason that some of the most ###### politicians, for better or worse, are ###### known as outstanding orators, able to ###### large and diverse crowds with powerful ######. But it's not just about the ###### they choose; the same paragraph on ###### carrots might sound boring in a ###### speaker's voice but riveting when recited ###### a Shakespearean actor.]]>
Politicians, Signorello said, "are the ###### public speakers because they face every ###### of audience, from elementary school to ###### old people."

Signorello wanted to see ###### there was any way to pin ###### what makes a politician an effective ######, by analyzing the strategies they use. ###### he analyzed the fundamental frequency (the ######) of the voices of two Democrats ###### two Republicans: Clinton, Sanders, Trump and ###### (who has dropped out of the ######).]]>
###### speaking to large crowds, the politicians ###### a wide pitch range - a ###### that Signorello and his colleagues showed ###### previous work would help them be ###### as charismatic.

"When the candidates addressed (######) audience of perceived and assessed lower ######, lower social status, they would use ###### high vocal pitch range, a high ###### pitch average and a wide loudness ######," Signorello said.]]>
"They have to diversify in ###### speech because they address an extremely ###### audience, so it's like they're focusing ###### subgroups of their audience and trying ###### fulfill each one's expectation" of what ###### charismatic leader sounds like, Signorello said.

###### when the politicians were addressing other ######, such as when Clinton spoke to ###### United Nations commission, when Sanders spoke ###### the U.S. Senate or when Trump ###### Fiorina spoke at the New Hampshire ###### Leadership Summit, the candidates limited their ###### to the low and medium frequencies.]]>
"When they address leaders, the ###### diversity is very, very restricted," he ###### out. "They're probably mostly male listeners ###### a certain age.]]>
When on ###### talk show chatting about nonpolitical things, ######, the politicians all used their normal ###### range, without "stretching" their frequencies or ######, he added.

So it sounds as ###### politicians have tapped into some vocal ###### for impressing an audience. But that ###### mean that they all share the ###### same behaviors; different candidates had their ###### particular quirks.]]>
"Given that he has a very ###### audience in terms of age, cultural ######, gender, he has to diversify a ###### because he wants to be perceived ###### charismatic by everyone," Signorello said of ######.

Next, the scientists also want to ###### whether politicians in other countries share ###### behavioral patterns to those in the ###### States, he added.]]>
