Communication system and terminal device
A communication system according to the present invention includes a plurality of terminal devices that are able to communicate mutually. Each of the terminal devices includes a voice input conversion device, a voice transmitting device, a voice receiving device, and a voice reproducing device. When there is a plurality of voice signals which has not been completed reproduction, the voice reproducing device reproduces after arranging the voice signals so that respective voices corresponding to the respective voice signals do not overlap.
1. A communication system comprising:
a plurality of terminal devices; and
a server that is capable of communicating with each of the plurality of terminal devices;
wherein the each of the plurality of terminal devices comprises:
a voice input conversion device that, when a user inputs a voice, converts the voice into voice information;
a voice information transmitting device that obtains first location information indicating a current location of a navigation device from the navigation device, adds the first location information to the voice information, and transmits the voice information to the server;
a first voice information receiving device that receives voice information transmitted from the server;
a voice reproducing device that reproduces a voice based on the voice information received; and
an information request transmission device that obtains second location information indicating at least the current location of the navigation device from the navigation device and transmits an information request including the second location information to the server, and
wherein the server comprises:
a second voice information receiving device that receives the voice information transmitted from the each of the plurality of terminal devices;
an accumulating device that accumulates the voice information received by the second voice information receiving device;
an information request receiving device that receives the information request transmitted from the each of the plurality of terminal devices;
a peripheral area setting device that sets a peripheral area of the navigation device based on the second location information included in the information request received by the information request receiving device;
an extraction device that extracts voice information transmitted from a location included in the peripheral area set by the peripheral area setting device based on the first location information; and
a delivering device that delivers the voice information extracted by the extraction device to a terminal device corresponding to the information request.
2. The communication system according to claim 1 , wherein the voice reproducing device reproduces once again the voice already reproduced at a specific command by the user.
3. The communication system according to claim 1 , wherein the second location information indicates a past location of the navigation device in addition to the current location of the navigation device.
4. The communication system according to claim 3 , wherein the peripheral area setting device sets an area in a traveling direction side of the navigation device as the peripheral area.
5. The communication system according to claim 1 , wherein the second location information indicates a destination and a route to the destination of the navigation device in addition to the current location of the navigation device.
6. The communication system according to claim 5 , wherein the peripheral area setting device sets an area along a scheduled traveling route of the navigation device as the peripheral area.
