Abstract

PURPOSE: A method for processing a voice command during telephone conversation is provided to select a desired menu with a user's voice command and to execute the function of a desired item. CONSTITUTION: If a user pushes a voice command button, a phone makes the call line with the other side mute(S1) and modifies the call path suitably for voice recognition(S2). The phone outputs a beef sound to request the user to convey a voice command(S3). The phone enables the interrupt of a GPIO(General Purpose I/O)(S4). Then the phone stores the data inputted through the GPIO(S5) and releases the call mute state with the other side(S6). The phone recognizes the user's voice command in the traffic state, executes a relevant function, and waits for the next command(S7,S8).

전화기의 통화 중 음성명령 처리방법{VOICE INSTRUCTION PROCESSING METHOD DURING TELEPHONE CONVERSATION}How to handle voice commands during phone calls {VOICE INSTRUCTION PROCESSING METHOD DURING TELEPHONE CONVERSATION}

본 발명은 전화 통화 상태에서 음성 명령을 사용할 수 있게 하는 기술에 관한 것으로, 특히 전화 통화 중 음성 명령으로 원하는 메뉴를 선택하고 그 중에서 원하는 항목의 기능을 실행시키는데 적당하도록 한 전화기의 통화 중 음성명령 처리방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for enabling a voice command in a phone call state, and in particular, to process a voice command during a call of a telephone so as to be suitable for selecting a desired menu with a voice command during a phone call and executing a function of a desired item therefrom. It is about a method.

종래 전화기의 음성인식 기술은 대기 상태에서만 사용할 수 있었다. 예를 들어, 음성 다이얼 기능을 이용하고자 하는 경우 대기 상태에서 음성인식 메뉴로 접근하면 안내 멘트가 재생 출력되고, 이후 사용자가 발성하는 음성 명령을 인식하여 해당 기능을 수행하도록 되어 있었다.The voice recognition technology of the conventional telephone can be used only in the standby state. For example, if the user wants to use the voice dial function, when the user approaches the voice recognition menu in the standby state, the announcement is reproduced and output, and the user recognizes the voice command spoken and then performs the corresponding function.

이와 같이 종래의 전화기에 있어서는 대기 상태에서만 음성인식 기능을 사용할 수 있게 되어 있는데, 그 이유는 이동전화기 내부의 하드웨어와 밀접한 관계가 있는 운영체제(OS: Operating System) 상에서 통화 중 음성명령을 실시간으로 인식하고 처리할만한 여유가 없기 때문이다.As described above, in the conventional phone, the voice recognition function can be used only in the standby state. The reason is that the voice command is recognized in real time on an operating system (OS) that is closely related to the hardware inside the mobile phone. Because you can't afford to handle it.

즉, 전화기의 내부에서 음성신호를 압축,신장 기능을 담당하는 보코더가 공중파로 송수신되는 음성신호를 처리하고 있는 상태에서 음성명령을 처리하기 위해서는 그 보코더를 다시 초기화 시켜야 하는데, 이와 같은 경우 상대방과의 통화가 끊기는 문제가 발생되기 때문이다.That is, in order to process voice commands while the vocoder in charge of the voice signal compression and extension process the voice signal transmitted and received over the air, the vocoder must be re-initialized. This is because the call is disconnected.

이와 같이 종래의 전화기에 있어서는 반드시 대기 상태에서만 음성인식 기능을 사용할 수 있게 되어 있어 전화 번호부 등을 검색하거나 기타 원하는 서비스를 받고자 할 때, 귀에서 전화기를 뗀 후 키이패드를 이용하여 명령어를 입력해야 하는 불편함 있었다.In the conventional phone, the voice recognition function can be used only in the standby state. When searching for a phone book or other desired service, the user must turn off the phone from the ear and input a command using the keypad. There was discomfort.

따라서, 본 발명의 목적은 전화 통화 중 음성 명령으로 원하는 메뉴를 선택하고 그 중에서 원하는 항목의 기능을 선택하여 실행시키는 전화기의 통화 중 음성명령 처리방법을 제공함에 있다.Accordingly, it is an object of the present invention to provide a method for processing a voice command during a call of a telephone to select a desired menu as a voice command during a phone call and to select and execute a function of a desired item therefrom.

도 1은 본 발명에 의한 전화기의 통화 중 음성명령 처리방법의 신호 흐름도.1 is a signal flow diagram of a voice command processing method of a telephone call according to the present invention.

***도면의 주요 부분에 대한 부호의 설명****** Description of the symbols for the main parts of the drawings ***

S1-S8 : 제1-8단계S1-S8: Steps 1-8

본 발명에 의한 전화기의 통화 중 음성명령 처리방법은, 전화기의 키패드 상에 음성명령 버튼이 눌리면 상대방과의 통화 라인을 뮤트시키고 통화 경로를 음성인식에 적당하도록 변경한 후, 비프음을 출력하고 코덱의 음성 데이터를 입력받는 지피아이오의 인터럽트를 인에이블시키는 제1단계와; 상기 지피아이오를 통해 입력되는 데이터를 램에 저장한 다음 상대방과의 통화 뮤트 상태를 해제시키는 제2단계와; 트래픽 상태에서 사용자가 하달하는 음성명령을 인식하여 해당 기능을 수행한 후 다음 명령을 대기하는 제3단계로 이루어지는 것으로, 이와 같이 이루어지는 본 발명의 작용을 첨부한 도 1을 참조하여 상세히 설명하면 다음과 같다.In the method of processing a voice command during a call of the telephone according to the present invention, when a voice command button is pressed on the keypad of the telephone, the call line with the other party is muted, the call path is changed to be suitable for voice recognition, and a beep sound is output. A first step of enabling an interrupt of the guipia I for receiving the voice data of the first step; A second step of storing the data input through the guipia, in a RAM, and then releasing a call mute state with a counterpart; Recognizing the voice command received by the user in the traffic state is performed as a third step of waiting for the next command after performing the function, when described in detail with reference to Figure 1 attached to the operation of the present invention made as follows same.

전화 통화 중 사용자가 음성인식 기능을 이용하기 위하여 전화기의 키패드 상에 마련된 음성명령 버튼을 누르면 사용자의 음성명령에 따라 해당 기능을 수행하는 음성인식모드를 설정하기 위해, 상대방과의 통화 라인을 뮤트시킴과 아울러 통화 경로를 음성인식에 적당하도록 변경한다.(S1,S2)When the user presses the voice command button provided on the keypad of the telephone to use the voice recognition function, the call line with the other party is muted to set the voice recognition mode to perform the corresponding function according to the user's voice command. In addition, the call path is changed to be suitable for speech recognition (S1, S2).

즉, 음성명령 버튼이 눌리면, 보코더 뮤트(Vocoder mute) 상태가 되고, 이에 의해 상대방과의 통화 상태는 묵음 상태가 된다.That is, when the voice command button is pressed, it becomes a Vocoder mute state, whereby the call state with the other party is muted.

이후, 사용자로 하여금 음성명령을 하달하라는 안내 멘트로 비프(beep)음을 출력하고, 코덱(CODEC)의 음성 데이터를 입력받는 지피아이오(GPIO: General Purpose I/O)의 인터럽트를 인에이블시킨다.(S3,S4)Thereafter, the user outputs a beep sound as a guide for requesting a voice command and enables an interrupt of a GPIO (General Purpose I / O) that receives voice data of a codec. (S3, S4)

이어서, 상기 GPIO를 통해 입력되는 데이터를 램에 저장한 다음 상대방과의 통화 뮤트 상태를 해제시킨다.(S5,S6)Subsequently, the data input through the GPIO is stored in the RAM, and then the call mute state with the counterpart is released (S5, S6).

트래픽 상태에서 사용자가 하달하는 음성명령을 인식하여 해당 기능을 수행한 후 다음 명령을 대기하게 된다.(S7,S8)In the traffic state, the user recognizes a voice command from the user and performs the corresponding function, and then waits for the next command. (S7, S8)

상기 음성명령어 인식과정에서, 사용자가 하달하는 음성 명령어를 버퍼에 저장하고, 그 버퍼에 저장된 명령어를 데이터베이스의 기준 패턴들과 비교하여 일치하는 기준패턴이 존재하는 경우 해당 메뉴 수행부로 분기하여 요구된 기능을 수행하게 된다.In the voice command recognition process, the voice command received by the user is stored in a buffer, and the command stored in the buffer is compared with the reference patterns of the database, and if there is a matching reference pattern, the function branches by branching to a corresponding menu execution unit. Will be performed.

이상에서 상세히 설명한 바와 같이 본 발명은 전화 통화 중 음성 명령으로 원하는 메뉴를 선택하고 그 중에서 원하는 항목의 기능을 선택하여 실행시킬 수 있게 함으로써, 상대방과의 통화가 좀더 자유로워지는 효과가 있다.As described in detail above, the present invention enables a user to select a desired menu using a voice command during a phone call and to select and execute a function of a desired item, thereby making the call with the other party more free.
