Voice Coach Stewart Pearce Shares Interesting Revelations In New Book About Princess Diana

Internationally renowned voice and presentation coach Stewart Pearce has some interesting revelations about how he helped Princess Diana find her voice.

In his upcoming book titled "Diana The Voice of Change," Pearce details how the late princess transformed from being a "demure and pained young woman" to an "assure, powerful humanitarian leader."

Diana was aware that her voice was not powerful, Pearce told People. "She knew that her voice was a voice of submission, not a voice of triumph. She wanted to find that," he explained.

He also recalled one instance in which the late mother of Prince William and Prince Harry had been "put to test" while receiving an award in the Big Apple. While talking about her sons, Princess Diana was asked by a member of the audience where the two boys were. In response, Princess Diana calmly said, "They're at school, as all good children should be, and enjoying themselves."

Princess Diana then received a 10-minute standing ovation from the audience. According to Pearce, it was a moment of present-mindedness that the late Princess of Wales had not accomplished before.

"That was a real point of triumph, that she was able to move forward and be that present and not feel immediately intimidated by the energy that was being thrown at her, which was rather unfortunate and immensely public," Pearce told the publication.

"It could have gone anywhere. It was obviously quite an aggressive demand upon her, but she was able to stand her ground, remain absolutely centered, and say what she felt," he said further.

Pearce also told Us Weekly that Princess Diana had given him permission to write a book about her, but on one condition: It should only be published when both Prince William and Prince Harry are already married.

"Also, with all the things that are going on with Harry and Meghan, I thought it was really important to step forward and say, 'OK, well, their mother was one of the first great voices of change.' And now Meghan is becoming another great voice of change and [here's] how we can support them and how we can support [all women] in this endeavor," Pearce explained.

Princess Diana died in August 1997 from the injuries she sustained in a car crash in the Pont de I'Alma tunnel in Paris. Her partner, Dodi Fayed, and driver, Henri Paul, were pronounced dead at the scene. Their bodyguard, Trevor Rees-Jones, survived the accident but was seriously injured.

"Diana The Voice of Change" will be released in bookstores on June 15.
