## Abstract

Each of plural dialogue devices generates proposition information that is an utterance indicating a proposition for passengers who are on board plural vehicles, based on an utterance submitted by a passenger and current destination information and past destination information. The dialogue device transmits the generated proposition information to other dialogue device.

## Claims

### Claim 1

A voice output system comprising a plurality of voice output devices that are interconnected via a network,
wherein each of the plurality of voice output devices is mounted in a different one of a plurality of vehicles, and
wherein each of the plurality of voice output devices includes:
a memory; and
a processor coupled to the memory and configured to:
acquire an utterance from a passenger who is on board one of the plurality of vehicles;
generate proposition information that is an utterance indicating a proposition for respective passengers who are on board the plurality of vehicles, based on the acquired utterance and at least one of current destination information or past destination information of the plurality of vehicles;
output the generated proposition information;
transmit the generated proposition information to other voice output device that is mounted in a vehicle, which has a common current destination information;
receive the proposition information transmitted from the other voice output device; and
output the received proposition information.

### Claim 2 (depends on 1)

The voice output system according to claim 1, further comprising a further voice output device that is installed at a place different from the plurality of vehicles,
wherein the processor in the further voice output device is further configured to acquire an utterance from a user in a vicinity of the further voice output device.

### Claim 3

A non-transitory storage medium storing a program that is executed in each of a plurality of voice output devices, each of which is mounted in a different one of a plurality of vehicles, the program causing a computer to execute processing comprising:
acquiring an utterance from a passenger who is on board one of the plurality of vehicles;
generating proposition information that is an utterance indicating a proposition for respective ones of the passengers who are on board the plurality of vehicles, based on the acquired utterance and at least one of current destination information or past destination information of the plurality of vehicles;
outputting the generated proposition information;
transmitting the generated proposition information to other voice output device that is mounted in a vehicle, which has a common current destination information;
receiving proposition information transmitted from the other voice output device; and
outputting the received proposition information.

### Claim 4

A voice output method that is performed in each of a plurality of voice output devices, each of which is mounted in a different one of a plurality of vehicles, the method comprising:
acquiring an utterance from a passenger who is on board one of the plurality of vehicles;
generating proposition information that is an utterance indicating a proposition for respective passengers who are on board the plurality of vehicles, based on the acquired utterance and at least one of current destination information or past destination information of the plurality of vehicles;
outputting the generated proposition information;
transmitting the generated proposition information to other voice output device that is mounted in a vehicle, which has a common current destination information;
receiving the proposition information transmitted from the other voice output device; and
outputting the received proposition information.
