Why not recruit a train announcer?

Announcers on trains generally don't recruit society.

An announcer should have national first-class and second-class Putonghua qualifications.

The announcer of the railway station broadcasts through artificial intelligence synthesis. Its basic requirements are as follows: First, Mandarin is relatively standard, with clear words and in line with passenger identification. Second, there are frequent trains entering and leaving the station, and the time difference interval is small. Prompt follow-up in the waiting room can only be achieved through H-engineering intelligent synthesis. Third, the announcer can intervene alone under special circumstances, such as lost and found passengers, lost children, sudden illness of passengers, and need assistance.
