Automation of telephone operator assistance calls
First Claim
1. In a telecommunications system, comprising a switching system having a switching network with a plurality of ports for connection to an operator position and control means for controlling said network, a method of providing voice message service, comprising the steps of:
- connecting an incoming call, destined for a called customer, via one of said ports to automated operator position means for processing operator assistance calls, said position means comprising means for recognizing speech and means for interfacing with said switching system via an Integrated Services Digital Network (ISDN) interface, wherein said means for recognizing speech comprises speech processor means, bulk storage means and data processing means each shared among a plurality of position means; and
if a prespecified spoken command is detected by said position means, transmitting a connect message to said control means, said connect message being essentially the same as a connect message from an attended operator position, for requesting connection of said call to means for recording a message for subsequent delivery to said called customer.

Abstract
This invention relates to methods and apparatus for automatically processing operator assistance calls. A caller is connected to an automated operator position. The automated position has speech recognition facilities to replace those of an operator, has announcement capabilities to replace those of an operator, and has control apparatus for transmitting and receiving the same set of messages transmitted and received by an operator position. Advantageously, the operator assistance switch has the same interface to an automated position as to an operator position and interacts with the two identically. Since the capabilities of the automated position are limited by its program, the automated position switches a call to an automated position when a situation occurs for which it has not been programmed. Advantageously, a switch need not be specially programmed to communicate with an automated position. Advantageously, new operator assistance services can be provided automatically without rewriting the complex control software of the switch. The invention further relates to the use of automated operator positions for providing spontaneous voice message service wherein a caller converts a call to a message call if the called party does not answer or is busy, and to a method of recognizing a voice specified destination and establishing a call to that destination.
