@vchan118: The Moment Prince William Spoke His First Words in Public (1984). On June 12, 1984, one-year-old Prince William was filmed playing in the gardens of Kensington Palace with his mother and father, Prince Charles, Prince of Wales, and Diana, Princess of Wales. In front of a host of reporters, photographers, and television news crews, William toddled across the lawn, kicked a ball, and played on a swing. His fascination with the cameras surrounding him was matched only by his father, who was heard discussing emerging electronic news gathering (ENG) technology with an ITN crew. The moment is often remembered as the first time William was heard speaking in public, a week before his second birthday.
