Abstract:
A method of receiving a call from a first caller that is requesting for assistance with a product. Once the call center receives the call, a call-processing switch routes the first caller to a first agent. Once the caller is routed to the first agent, a first message is transmitted to both the first caller&#39;s terminal and the first agent&#39;s terminal. After the first message is presented to the first caller and the first agent, the call-processing switch will monitor the communications stream for distress. During monitoring of the communications stream, the call-processing switch will estimate whether a level of distress is present in the communications stream. If it is estimated by the call-processing switch that there is distress present in the communications stream, the call-processing switch will transmit a second message to the first caller&#39;s terminal and the first agent&#39;s terminal.

Description:
FIELD OF THE INVENTION 
     The present invention relates to telecommunications in general, and, more particularly, to telecommunications call centers. 
     BACKGROUND OF THE INVENTION 
     In many situations, when a product is purchased, the product can be too difficult for the average person to assemble, operate or troubleshoot. These problems could be resolved by contacting a call center agent for assistance. 
     Once the caller is connected to a call center agent, the caller is able to ask questions pertaining to their problem with the product. However, in many occasions, the call center agent must reference an electronic manual to pinpoint a solution to the problem. This situation occurs, for example, when the call center agent:
         i. does not remember the solution to the problem, or   ii. is not familiar with the problem, or   iii. desires to verify his/her proposed solution before presenting it to the caller, or   iv. any combination of i, ii, and iii.       

     In this example, the caller becomes angry, annoyed, frustrated, etc., since he/she is being put-on-hold for an extended period of time until the call center agent is able to pinpoint the solution in the electronic manual. On the other hand, the call center agent may also become angry, annoyed, frustrated, etc., since the solution to the caller&#39;s problem is not readily apparent to the call center agent. 
     This poor quality-of-service may result in a loss of potential customers. Furthermore, the call center&#39;s expenses may increase due to the fact that additional training is necessary to update an agent&#39;s knowledge in a particular topic. 
     Therefore, there exists a need for a more accommodating call center that can assist callers with quick and reliable product information. 
     SUMMARY OF THE INVENTION 
     The present invention provides a call center that avoids some of the costs and disadvantages associated with call centers in the prior art. 
     In accordance with the illustrative embodiment, a call center receives a call from a first caller that is requesting for assistance with a product. Once the call center receives the call, a call-processing switch routes the first caller to a first agent. 
     Once the caller is routed to the first agent, a first message is transmitted to both the first caller&#39;s terminal and the first agent&#39;s terminal. After the first message is presented to the first caller and the first agent, the call-processing switch will monitor the communications stream for distress. During monitoring of the communications stream, the call-processing switch will estimate whether a level of distress is present in the communications stream. If it is estimated by the call-processing switch that there is distress present in the communications stream, the call-processing switch will transmit a second message to the first caller&#39;s terminal and the first agent&#39;s terminal. 
     After the second message is presented to the first caller and the first agent, the call-processing switch will again monitor the communications stream for distress. During monitoring of the communications stream, the call-processing switch will estimate whether a level of distress is present in the communications stream. 
     If there is no distress present in the communications stream, the call-processing switch will build a model based, at least in part, on the effectiveness of the first message and the second message in alleviating the distress of first caller and the first agent. This model will be used in future calls to assist the call-processing switch in choosing which messages to display to a caller and an agent in analogous circumstances. 
     When a second agent is presented with analogous circumstances with a second caller, the call-processing switch will transmit the first message and the second message to the second caller&#39;s terminal and the second agent&#39;s terminal. The messages will be transmitted in an order based, at least in part, on the first level of distress and the second level of distress. 
     The illustrative embodiment of the present invention comprises: 
     (i) receiving a communication stream from a first caller C 1  for a first agent A 1 , (ii) transmitting a first message to the first agent A 1 , (iii) estimating a first level of distress in the first caller C 1  after the first message is presented to the first agent A 1  by analyzing the semantic content of the communication stream from the first caller C 1  to the first agent A 1 , (iv) transmitting a second message to the first agent A 1 , (v) estimating a second level of distress in the first caller C 1  after the second message is presented to the first agent A 1  by analyzing the semantic content of the communication stream from the first caller C 1  for the first agent A 1 , and (vi) transmitting the first message and the second message to a second agent A 2  in an order based, at least in part, on the first level of distress and the second level of distress.
