During the 1970s and 1980s, Audichron began to manufacture other kinds of equipment besides time and temperature machines.
[3][4] The Audichron sales force found sponsors, such as banks,[5] for its time and temperature machines in a city.
Once a sponsor had been obtained, Audichron would lease the machines to the local phone company.
From the 1980s, the female voices were provided by Barbe and Fleet; they were joined by Joanne Daniels, who did number-change announcements and who was the "time lady" for most of the Western United States.
[9] The Audichron Company was acquired in 1989 by Electronic Tele-Communications, a manufacturer of telephone answering machines that was founded in 1949.
