EQUIPMENT FOR SENDING DIGITALLY PRE-STORED VOICE ANNOUNCEMENTS TO THE SUBSCRIBERS CONNECTED TO A TELEPHONE NETWORK

摘要

Equipment for providing digitally pre-encoded voice announcements to subscribers for utilisation in a telephone network consists of one or more voice units each connected by independent lines to a telephone network. Each unit has an announcement data base which contains a complete set of announcements to be supplied to the subscribers, a computer which manages the recovery of an announcement from the data base and its forwarding to subscribers, and an interface to the network, for temporary storage of at least part of the announcements prior to forwarding, processing of telephone network signals, their conversion into analog form if required, and supervision of the equipment.
