Abstract A contact center support system is a system that supports a contact center and includes a control unit that executes a plurality of processes for communication performed between an operator of the contact center and a customer, in which the communication includes a call between the operator and the customer, the plurality of processes include at least a voice recognition process of recognizing at least a content of the customer's utterance from a voice of the call, an emotion recognition process of recognizing at least the customer's emotion from the voice of the call, and a filtering process of filtering the content of the utterance of the customer and/or the operator in the call, and the control unit simultaneously executes the processes included in the plurality of processes in parallel. ## Claims ### Claim 1 A contact center support system that supports a contact center, the contact center support system comprising: a control unit that executes a plurality of processes for communication performed between an operator of the contact center and a customer, wherein the communication includes a call between the operator and the customer, the plurality of processes include at least a voice recognition process of recognizing at least a content of the customer's utterance from a voice of the call, an emotion recognition process of recognizing at least the customer's emotion from the voice of the call, and a filtering process of filtering the content of the utterance of the customer and/or the operator in the call, and the control unit simultaneously executes the processes included in the plurality of processes in parallel. ### Claim 2 (depends on 1) The contact center support system according to claim 1, wherein a response to the customer in the call is made by a voicebot that utters the content of text input by the operator or by the operator's utterance, and the control unit reproduces a standby voice when the operator's input of text or a voice is not detected for a predetermined period of time during the call. ### Claim 3 (depends on 2) The contact center support system according to claim 2, wherein the response to the customer in the call is made by the utterance of the voicebot, and a voice uttered by the voicebot is subjected to a voice synthesis process so as to have the same tone as the standby voice and is reproduced subsequently to the reproduction of the standby voice. ### Claim 4 (depends on 2) The contact center support system according to claim 2, wherein the response to the customer during the call is made by the operator's utterance, and the voice uttered by the operator is subjected to a voice synthesis process and/or a voice quality conversion process so as to have the same tone as the standby voice and is reproduced subsequently to the reproduction of the standby voice. ### Claim 5 (depends on 3) The contact center support system according to claim 3, wherein the voice recognition process includes a process of converting the voice uttered by the customer in the call into text, the filtering process includes a masking process of, when a predetermined word is included in the text description, converting the word into another word to present the text to the operator in a form in which a content represented by the word is concealed, and when the response to the customer is made by the utterance of the voicebot, the control unit restores the word to the word before conversion by the masking process when the other word is included in the text input by the operator. ### Claim 6 (depends on 1) The contact center support system according to claim 1, wherein the control unit executes the plurality of processes as a synchronous process. ### Claim 7 (depends on 1) The contact center support system according to claim 1, wherein the control unit executes the plurality of processes as an asynchronous process. ### Claim 8 A contact center support system that supports a contact center, the contact center support system comprising: a control unit that executes a plurality of processes for communication performed between an operator of the contact center and a customer, wherein the communication includes a call between the operator and the customer, the plurality of processes include at least a voice recognition process of recognizing at least a content of the customer's utterance from a voice of the call, an emotion recognition process of recognizing at least the customer's emotion from the voice of the call, and an emotion synthesis process of analyzing the voice of the call, alleviating or invalidating parameters for determining the customer's emotion in the voice, and resynthesizing the voice, the parameters include at least a pitch of the voice that represents the tone of the customer's voice or a voice volume of the voice that represents a volume of the customer's voice, and the control unit simultaneously executes the processes included in the plurality of processes in parallel. ### Claim 9 (depends on 8) The contact center support system according to claim 8, wherein a response to the customer in the call is made by a voicebot that utters the content of text input by the operator or by the operator's utterance, and the control unit reproduces a standby voice when the operator's input of text or a voice is not detected for a predetermined period of time during the call. ### Claim 10 (depends on 9) The contact center support system according to claim 9, wherein the response to the customer in the call is made by the utterance of the voicebot, and a voice uttered by the voicebot is subjected to a voice synthesis process so as to have the same tone as the standby voice and is reproduced subsequently to the reproduction of the standby voice. ### Claim 11 (depends on 9) The contact center support system according to claim 9, wherein the response to the customer during the call is made by the operator's utterance, and the voice uttered by the operator is subjected to a voice synthesis process and/or a voice quality conversion process so as to have the same tone as the standby voice and is reproduced subsequently to the reproduction of the standby voice. ### Claim 12 (depends on 10) The contact center support system according to claim 10, wherein the voice recognition process includes a process of converting the voice uttered by the customer in the call into text, the filtering process includes a masking process of, when a predetermined word is included in the text description, converting the word into another word to present the text to the operator in a form in which a content represented by the word is concealed, and when the response to the customer is made by the utterance of the voicebot, the control unit restores the word to the word before conversion by the masking process when the other word is included in the text input by the operator. ### Claim 13 (depends on 8) The contact center support system according to claim 8, wherein the control unit executes the plurality of processes as a synchronous process. ### Claim 14 (depends on 8) The contact center support system according to claim 8, wherein the control unit executes the plurality of processes as an asynchronous process. ### Claim 15 A contact center support method of supporting a contact center, wherein a computer including at least a processor and a storage apparatus includes a control unit that executes a plurality of processes for communication performed between an operator of the contact center and a customer, the communication includes a call between the operator and the customer, the plurality of processes include a voice recognition process of recognizing at least a content of the customer's utterance from a voice of the call, and an emotion recognition process of recognizing at least the customer's emotion from the voice of the call, and include at least any one of a filtering process of filtering the content of the utterance of the customer and/or the operator in the call, and an emotion synthesis process of analyzing the voice of the call, alleviating or invalidating parameters for determining the customer's emotion in the voice, and resynthesizing the voice, and the control unit simultaneously executes the processes included in the plurality of processes in parallel.
