Semi automated announcements supported by a computer program using pre recorded and compressed recordings of all kinds of repeated announcements like dates, times, bus numbers, destinations departures, arrivals, hints, whatever.
It goes like this:
The user/employee on duty uses a computer, which contains the CALL program
and all announcement data in MP3 format.
He has a numbered
list of the announcement data written on paper or in the program window of CALL10
on the computer screen.
In our bus example
he knows or sees the number of the arriving or departing busses. He knows
or departure he just types the bus number and the destination number from
the list and hits the space key on the computer keyboard.
At simple announcements
he just types in the announcement number.
the program finds the data belonging to the announcements, puts the texts
together in until 10 languages and plays them using the client's existing P.A.
