Abstract

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 means 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. 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.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 78 words
In a telephone switching system having a switching network, a method for serving a call whose destination is specified by dialed signals from a caller, comprising: in automated equipment, comprising speech recognition equipment, analyzing speech signals from a caller received via said network to identify a class of said call; responsive to the class identification, sending a switching network request message from said automated equipment to said system for requesting connection of said call to a call destination.
Claim 2
Dependent Claim 78 words
In a telephone switching system having a switching network, a method for serving a call whose destination is specified by dialed signals from a caller, comprising: in automated equipment, comprising speech recognition equipment, analyzing speech signals from a caller received via said network to identify a class of said call; responsive to the class identification, sending a switching network request message from said automated equipment to said system for requesting connection of said call to a call destination.
Claim 3
Dependent Claim 38 words
The method of claim 1 wherein said system is further connected to at least one attended operator position and wherein said request message is essentially the same as a corresponding request message transmitted from an attended operator position.
Claim 4
Dependent Claim 21 words
The method of claim 1 further comprising: establishing said requested connection; and monitoring said requested connection for detecting an answer signal.
Claim 5
Dependent Claim 68 words
The method of claim 3, wherein said automated equipment comprises means for announcing messages further comprising: responsive to detecting said answer signal, announcing from said automated equipment to said called terminal a request to issue a prespecified command; and responsive to detecting said prespecified command from said called terminal, transmitting a second data message to said switch to request a connection between said calling and said called terminal.
Claim 6
Dependent Claim 46 words
The method of claim 4 wherein said system is further connected to at least one attended operator position and further comprising: responsive to detecting another command from said called terminal, transmitting a request to said switch to connect said called terminal to an attended operator position.
Claim 7
Dependent Claim 12 words
The method of claim 4 wherein said command is a speech command.
Claim 8
Dependent Claim 26 words
The method of claim 4 wherein said automated equipment is further adapted to detect dual tone multifrequency (DTMF) signals and said command is a DTMF signal.
Claim 9
Dependent Claim 45 words
The method of claim 1 wherein said system is further connected to at least one attended operator position and further comprising the step of: preceding said analyzing step, prompting, from said automated equipment, a calling customer at said calling customer terminal to issue a command.
Claim 10
Dependent Claim 46 words
The method of claim 1 further comprising a method of providing voice message service, comprising the step of: responsive to detection of a prespecified spoken command by said position means, connecting said call to means for recording a message for subsequent delivery to said called customer.
Claim 11
Dependent Claim 52 words
The method of claim 9 further comprising the steps of: detecting a busy condition reported for said called customer, and responsive to said detection of a busy condition, announcing to said incoming call an offer to provide voice message service if a caller of said incoming call provides said prespecified spoken command.
Claim 12
Dependent Claim 84 words
The method of claim 1 wherein said destination is only an intermediate destination specifying said automated equipment further comprising a method of establishing another call comprising the steps of: responsive to receiving a number for identifying a calling customer, establishing a connection to said automated equipment; in said automated equipment, recognizing a spoken command from said calling customerfor identifying a number of a called customer corresponding to said spoken command; and establishing said another call to a telephone station identified by said identified number.
Claim 13
Dependent Claim 90 words
