An automated announcement system allows messages to be played on a public address system and/or displayed on a display device in accordance with a predetermined schedule, which can be modified automatically to maintain a predetermined minimum interval between messages. Conflicts between messages to be played at the same time are detected and resolved by assigning priorities to messages based on deficits in the number of times each message has been played. Additional features of the automated announcement system include programmable control over announcement volume levels, the ability to input scheduling parameters which apply to specific announcements or to all announcements, the use of multi-level password protection to restrict specific system functions to authorized users, and an interface which allows live announcements to be made without interference from stored or recorded announcements.
