IS this a familiar face? Maybe not, but you know Cheri Chan Yu-yan better than you think.
The chances are you listen to her voice at least a dozen times a week, and you know her words almost by heart.
And what she says is: ''The next stop is Admiralty.'' Cheri Chan's is the pure, sweet voice of the MTR, and it is a voice that Hong Kong has taken to its heart.
Every time you get on and off the train, her soft lullaby is there with you.
Children learn their English by it. Tourists learn their first words of Cantonese.
Marketing executives looking for a voice over for their adverts ask for ''A voice like the MTR''.
Even when the carriage is stuffed to bursting and the air-conditioning has packed in, somehow things seem better when Cheri tells you to: ''Please stand clear of the doors.'' So how does it feel to be almost an institution? ''I don't like travelling on the MTR. There is nothing worse than having your own voice boom down at you for seven stations. I often take the bus instead,'' she said.
