She has been going out with future king Prince William for eight years, but Kate Middleton's voice has always remained something of a mystery to the general public.
But now a video featuring the 27-year-old has appeared on YouTube giving viewers the chance to hear Kate speaking – albeit very briefly.
The footage was taken at the online marketing show in London around two weeks ago. Kate was attending on behalf of her parents' company, Party Pieces, which she has worked for over the last year.
In the 11-second-long clip, the Marlborough College-educated brunette can be heard saying: "It's very interesting. It's got some interesting lectures going on. It's brilliant."
