ABSTRACT:
An automatic message announcement system for announcing the approach, arrival, and departure of vehicles such as trains at a train station. An addressable voice memory is provided for storing sequences of voice segments which are read out upon receipt of announcement command input signals to form messages for announcing that a vehicle is approaching or has arrived or is departing, with specific information such as the vehicle's destination being included in the announcement by inserting the appropriate voice segments at the proper points in the sequence. The messages are composed in such a manner that the sequences of voice segments can be altered to form shorter, but still intelligible, messages if vehicles traffic is so heavy that one message is due for announcement before the previous announcement is completed. A priority selection circuit is provided for giving priority to the announcement command input signals, along with a memory for storing the addresses of the voice segments, a control circuit for reading out the memory content on the basis of the announcement command input signals and generating a message pattern to be announced, and an edition control circuit for supplying the appropriate addresses to the voice memory so that the proper voice segments can be read out in the desired sequence in order to produce the announcements.
