Hello, everybody, and please is not take care on the escalators.

Hold onto the Handra.

Oh, and your luggage.

Around 10 people a day get injured on the underground network.

I think everyone takes notice where the child says something.

Around 1/4 of a 1,000,000 people use Victoria Station in London each week day, and for the past few months they've been hearing an unusual voice.

Meet the station's newest and youngest safety announcer, nine year old Meghan.

Her proud parents both work at the station.

Hello, everybody, and pleases and take care on the escalators.

Hold onto the handrail and your luggage.

Megan's recorded announcement is designed to tackle a serious problem.

Around 10 people a day get injured on the underground network, but we have notices that when people do injure themselves, it's typically because they're not taking enough care when using stairs and escalators at Victoria alone.

On average, 15 people a month are injured this way.

For some passengers, at least, Megan's message seems to be getting through.

I think everyone takes notice where the child says something, and because they don't you know they always mean it.

So what does someone who studies the psychology of the human voice?

Make of this research shows that deeper adult voices are perceived by humans as having more authority, then hire voices so child's voice wouldn't have that authority.

But perhaps, is the shock factor off using a chance voice.

It may be just a short term result from this shock factor, but the station says injuries have dropped by nearly 2/3 since Megan's announcements started.
