The transmitting of the voice data of the voice recognition spoken word to the set-top box may include transmitting the voice data from which the ambient noise has been removed from the voice recognition spoken word.

Removing the sound data of the sound being output from the voice data through the set-top box in the speech recognition speech word; And a step of removing noise from the audio data from which the audio data has been removed, so that the final speech recognition speech may be recognized.

When the voice recognition spoken word is recognized, the remote control receiving a voice recognition mode activation command from the set-top box; And activating the voice recognition mode in response to the activation command.

Receiving voice data of voice recognition spoken words from a remote control; Removing sound data of sound being output through a set-top box from the sound data; And transmitting the voice data of the final voice recognition spoken word from which the sound data has been removed to a server, wherein the server recognizes the final voice recognition spoken word, and an operating method of a set-top box for voice recognition spoken word recognition Can be provided.

The voice data of the voice recognition spoken word received from the remote control may be voice data of the voice recognition spoken word from which ambient noise sensed through the microphone of the remote control has been removed.

The voice data of the final voice recognition spoken word is compared with the voice data of the set voice recognition spoken word preset in the server, and whether the final voice recognition spoken word and the set voice recognized spoken word are recognized according to whether or not they match. Can be determined.

Receiving whether or not the final voice recognition spoken word is recognized from the server; And when the final voice recognition spoken word is recognized, transmitting a command to activate the voice recognition mode of the remote control to the remote control.

According to an embodiment of the present invention, in order to improve a false recognition rate when recognizing a voice recognition spoken word for activating a voice recognition mode, an operation method in a remote control and a set-top box, and a remote control and a set-top box performing the same can be provided.

In step 201, the remote control may remove ambient noise.

In an embodiment, ambient noise detected by a microcontroller unit (MCU) included in the remote control may be removed at all times. Ambient noise may be input through a microphone of a remote control.

In an embodiment, the remote control may remove surrounding noise while the set-top box is operating and one or more contents are output to the display device. Or it can detect and remove noise that is defined as living noise.

In step 202, the remote control can detect the speech recognition speech.

In an embodiment, a voice recognition spoken word input from a user may be detected. The voice recognition spoken word input by the user's voice can be detected from the signal from which the ambient noise of the remote control has been removed. While the set-top box is operating and at least one content is output to the display device, a speech recognition speech word may be detected.

In another embodiment, when the set-top box is in the OFF state, the remote control may not detect the voice recognition spoken word.

In an embodiment, when there are a plurality of microphones included in the remote control, only the minimum microphone can be activated and the operation of the remaining microphones can be limited, and it is possible to detect whether or not a specific decibel (dB) or more voice is generated from the activated minimum microphone. , When a voice of more than a specific decibel is generated, the voice may be recognized by switching states such that a plurality of microphones operate.

In step 203, the remote control may transmit the voice data of the voice recognition spoken word to the set-top box.

In an embodiment, the remote control transmits voice data of a voice recognition spoken word irrespective of the ON/OFF state of the set-top box, and the set-top box may determine whether to receive the corresponding voice data based on the ON/OFF state.

In step 204, the set-top box may detect speech recognition speech.

In an embodiment, the set-top box can easily obtain information on content displayed on a TV screen. The sound data of the contents provided from the set-top box can be removed from the sound data from which the ambient noise received from the remote control is removed from the SoC (System on Chip) built into the set-top box.

For example, since the user is currently watching content through the TV, the operation of deleting sound data to be output through the TV may be effective in increasing the recognition rate of the sound data of the received speech recognition spoken word.

In one embodiment, the set-top box may remove noise from voice data of voice recognition speech words from which TV sound has been removed. By removing the noise twice over the remote control and the set-top box, it is possible to increase the recognition rate of speech recognition spoken words.

In step 306, the server may transmit the recognition result and service to the set-top box.

In an embodiment, a search result from the server or a voice command obtained by searching may be transmitted.

In step 307, the set-top box may output the received recognition result and provide a corresponding service.

In an embodiment, a searched content list may be provided in response to a voice command, a channel and/or a volume may be changed, or weather search results, real-time traffic information, and the like may be output on a TV screen.

In step 308, the set-top box may transmit an end command of the voice recognition mode to the remote control in response to receiving a result of the voice command.

In an embodiment, the set-top box may display a guide on the end of the voice recognition mode on one side of the TV screen.

In step 309, the remote control may disable the microphone.

In an embodiment, the deactivation of the microphone ends the activation of the microphone for the voice recognition mode, and an always-on listening function for voice recognition of the microphone may be executed to recognize the voice recognition spoken word to be input thereafter. have. When this function is executed, noise input to the microphone can be removed.
