You might not know the woman, but you surely would have heard that voice before.

Usharani D/O Mugiarayan is a 20-year public announcement veteran at Changi Airport.

She is one of the 16 all-women team that does announcements for the public address system in each terminal.

The 45-year-old's crisp vocals are neither digitally-altered nor pre-recorded and prepared to be broadcast by some automated system.

Each time a periodic call comes in from the information counter to relay a request for an announcement, the public address team quickly jots down the message on a notepad, prepares the script and proceeds to make the broadcast live.

To target the message at the correct group of passengers, each announcer is able to control the broadcast location exactly.

Announcements for all three terminals are made from the centralised public announcement headquarters at Terminal 2.

Between the 16 ladies on the team, they can make announcements in English, Chinese, Malay, Tamil and Japanese. The team receives yearly voice training and refreshers at top vocal communication centres.

However, it appears enunciation is not only key to doing the job.

In fact, Usharani received the President’s Distinguished Star Service Award in 2008 after helping an elderly tourist from London reunite with her lost item.

Seeing that the elderly lady was travelling alone in Singapore, Usha contacted her after work to check on the visitor, but ended up showing her around and having dinner together.
