OKCHEON, South Korea, Nov. 15 (Korea Bizwire) – A recent Korean study has taken a more scientific approach to explaining Donald Trump’s unprecedented victory in the U.S. presidential election.
Voice analyst Cho Dong-wook, a Chungbuk Provincial College professor, announced the results of a study Monday that said Trump’s voice was more stable and reliable during the presidential debates than Democratic candidate Hillary Clinton’s.
After dividing Mr. Trump’s speaking during the presidential debates into three sections, Cho found that both the pitch (frequency) and the intensity (decibel level) of his voice rose as the debates progressed, while his jitter (changes in frequency), shimmer (changes in amplitude), and harmonics-to-noise ratio lessened.
This, according to the professor, means that the president-elect was building energy as he spoke, while enunciating more clearly with less jitter, shimmer, and HNR, conveying higher stability and confidence.
Cho’s study also noted the difference between the highest and the lowest points of Trump’s speech frequencies, which were 163.410Hz and 159.812Hz, lower than Clinton’s at 320.765Hz and 299.540Hz – meaning that Trump’s speaking was more balanced, and he was delivering his opinion with a tone that the average audience member would find more reliable.
Meanwhile, Cho also discovered that Trump’s speech frequencies (147.182Hz – 159.663Hz) and decibel level (62.419dB – 64.590dB) dropped noticeably when talking about defense issues related to South Korea, Japan, and Saudi Arabia compared to North Korea and China (178.391Hz – 218.039Hz and 66.733dB – 67.013dB).
“A lower frequency and decibel level can indicate that he was making an uncandid remark,” he said. “But we felt a sense of sincerity when he was discussing North Korea and China.”
