CROSS-REFERENCE TO RELATED APPLICATION

This patent application is based on and claims priority pursuant to 35 U.S.C. § 119(a) to Japanese Patent Application No. 2019-195630, filed on Oct. 28, 2019, in the Japan Patent Office, the entire disclosure of which is hereby incorporated by reference herein.

BACKGROUND

Technical Field

Embodiments of the present disclosure relate to a communication system, a communication method, and a recording medium storing a program for executing a communication method.

Related Art

There are wireless communication systems in which terminal devices at remote sites perform remote communications, such as a conference among users at the remote sites, by transmitting and receiving images and sounds to and from each other to display the images on displays and output the sounds from speakers. Each terminal device includes a camera, a microphone, a display, and a speaker. An image captured by the camera of one of the terminal devices is displayed on the display of another one or more of the terminal devices, which is/are (a) counterpart communication terminal(s). In addition, voice acquired by the microphone of one of the terminal devices is output from the speaker of another one or more of the terminal devices, which is/are (a) counterpart communication terminal(s). Such a communication system allows an operator at a call center to talk on a call (for example, serve a guest or customer) while seeing a face of the guest who has visited a store. In addition, such a communication system also allows the guest to hear an explanation while seeing a face of the operator.

A technique for assisting a conversation is also known. In such a technique, a conversation analysis device analyzes a conversation in real time, analyzes receptivity of a conversation partner of a user and conversation skills of the user, and then extracts a user (influencer) having a large influence on a certain topic on another person.

SUMMARY

An exemplary embodiment of the present disclosure includes a communication system including a first terminal device, a second terminal device, and an advice providing device that includes circuitry. The first terminal device is operated by an operator. The second terminal device is operated by a guest. The second terminal device communicates with the first terminal device through a network. The circuitry of the advice providing device determines advice for the operator based on voice data including first voice data that is related to the operator and transmitted from the first terminal device and second voice data that is related to the guest and transmitted from the second terminal device. The circuitry of the advice providing device further transmits the advice to the first terminal device. The first terminal device receives the advice and displays, on a display, the advice.
