## Abstract

The voice recognition device according to the present disclosure includes a communication interface that communicates with an external device, a first microphone that collects sound to produce audio data, and a controller that analyzes the audio data produced by the first microphone, determines contents of a designation corresponding to an analysis result, and then controls its own device based on a determination result, and yet controls its own device to urge a user to use the external device when the contents of the designation corresponding to the analysis result cannot be determined.

## Claims

### Claim 1

A voice recognition system comprising:
a display device having a first microphone that collects sound to produce audio data; and
a portable device having a second microphone that collects sound to produce audio data,
wherein
the display device includes
a communication interface that communicates with the portable device; and
a controller that analyzes the audio data produced by the first microphone, and controls to urge a user to use the second microphone when the contents of the designation corresponding to the analysis result cannot be determined, and
wherein the controller, when the contents of the designation corresponding to the analysis result cannot be determined, controls the communication interface to transmit a command to the portable device to set the portable device to a mode in which the second microphone can be used.

### Claim 2 (depends on 1)

The voice recognition system according to claim 1,
wherein the display device further includes a monitor that displays an image,
the controller controls the monitor to display a message to urge a user to use the portable device having the second microphone when the contents of the designation corresponding to the analysis result cannot be determined.

### Claim 3

A voice recognition method comprising:
collecting sound to produce audio data by using a first microphone; and
analyzing the audio data to determine contents of a designation corresponding to an analysis result, and urging a user to use a portable device having a second microphone when the contents of the designation corresponding to the analysis result cannot be determined,
wherein when the contents of the designation corresponding to the analysis result cannot be determined, a command to set the portable device to a mode in which the second microphone can be used is transmitted to the portable device.

### Claim 4 (depends on 3)

The voice recognition method according to claim 3,
wherein when the contents of the designation corresponding to the analysis result cannot be determined, a message to urge a user to use the portable device is displayed.

### Claim 5

A voice recognition device comprising:
a communication interface capable of communicating with a plurality of portable devices;
a first microphone that collects sound to produce audio data; and
a controller that analyzes the audio data produced by the first microphone, and controls to urge a user to use anyone of the plurality of portable devices when contents of a designation corresponding to an analysis result cannot be determined,
wherein the controller, when the contents of the designation corresponding to the analysis result cannot be determined, controls the communication interface to transmit a command to at least one of the portable devices to set the at least one of the portable devices to a mode in which a second microphone can be used.

### Claim 6 (depends on 5)

The voice recognition device according to claim 5, further comprising:
a monitor that displays an image,
wherein the controller controls the monitor to display a message to urge a user to use anyone of the plurality of portable devices when the contents of the designation corresponding to the analysis result cannot be determined.
