ABSTRACT:
An elevator system having a plurality of elevator cars, and communication apparatus which includes a speech synthesizer for each car which provides audible, informative messages in its associted elevator car in response to its operation. Different messages may be simultaneously reproduced in the different elevator cars from a single vocabulary which is common to all messages and all elevator cars. A single central processing unit periodically replenishes the memory of each car's speech synthesizer before interruption can occur in the message due to lack of vocabulary information.
