Abstract

본 발명의 티거에너지를 이용한 더블토크 검출방법에 관한 것으로, 안내방송신호가 송출되면, 마이컴은 원래 안내방송신호의 프레임 티거에너지를 계산하여 메로리에 저장하고, 원래의 안내방송신호와 사용자 음성신호가 혼합되어 피드백되면 마이컴은 소정레벨로 보상한 다음 원래의 안내방송신호와 사용자 음성신호의 프레임 티거에너지를 계산하여 메모리에 저장한다. 그 다음, 마이컴은 메모리에 각각 저장되어 있는 원래 안내방송신호의 프레임 티거에너지와, 원래의 안내방송신호와 사용자 음성신호의 프레임 티거에너지를 비교하여 원래 안내방송신호와 사용자 음성신호의 프레임 티거에너지가 원래의 안내방송신호의 프레임 티거에너지보다 크면 사용자 음성신호가 존재하는 것으로 판단하여, 시간축 상에서 그 차이에 상응하는 위치에 발생되는 피이크의 시작점을 더블토크의 시작점으로 검출하므로써, 더블토크의 시작점을 보다 정확하게 검출할 수 있을 뿐만 아니라 사용자의 파열음이나 마찰음의 에너지를 정확하게 계산할 수 있도록 한 것이다.The present invention relates to a double-talk detection method using tigger energy, and when a guide broadcast signal is transmitted, the microcomputer calculates and stores the frame tigger energy of the original guide broadcast signal in a memory, and the original guide broadcast signal and the user's voice signal are stored. When mixed and fed back, the microcomputer compensates to a predetermined level and then calculates and stores the frame tigger energy of the original announcement signal and the user's voice signal in the memory. Next, the microcomputer compares the frame tigger energy of the original announcement broadcast signal stored in the memory with the frame tigger energy of the original announcement broadcast signal and the user's voice signal. If it is larger than the frame tigger energy of the original announcement signal, it is determined that the user voice signal exists, and the start point of the double torque is detected by detecting the start point of the peak generated at the position corresponding to the difference on the time axis as the start point of the double torque. Not only can it be accurately detected, but also the energy of the rupture or friction sound of the user can be calculated accurately.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 통상적인 안내방송 시스템의 개략적인 블럭구성도, 제2도는 본 발명의 바람직한 실시예에 따라 티거에너지를 이용하여 더블토크의 시작점을 검출하는 동작과정을 도시한 플로우차트.1 is a schematic block diagram of a conventional guide broadcasting system, and FIG. 2 is a flowchart illustrating an operation process of detecting a starting point of a double torque using tigger energy according to a preferred embodiment of the present invention.

Claims (1)

마이컴(200)의 제어신호에 의거하여 원래 안내방송신호가 송출되고 사용자 음성신호와 혼합된 다음 피드백되어 입력되는 더블토크의 시작점을 검출하는 방법에 있어서, 상기 송출되는 원래 안내방송신호의 프레임 티커에너지를 계산하여 메모리(100)에 저장하고, 상기 피드백되어 입력되는 원래 안내방송신호와 사용자 음성신호를 설정된 소장레벨로 보상한 다음 프레임 티거에너지를 계산하여 상기 메모리(100)에 저장하는 제1단계; 상기 제1단계에서 상기 메모리(100)에 저장되어 있는 원래 안내방송신호와 사용자 음성신호의 프레임 티거에너지를 상기 메모리(100)에 저장되어 있는 원래 안내방송신호의 프레임 티거에너지를 비교하여, 상기 메모리(100)에 저장되어 있는 원래 안내방송신호와 사용자 음성신호의 프레임 티커에너지가 상기 메모리(100)에 저장되어 있는 원래 안내방송신호의 프레임 티거에너지보다 크면 그 차이에 상응하는 시간축상에서의 피이크의 시작점을 더블토크의 시작점으로 검출하는 제2단계로 이루어진 것을 특징으로 하는 티거에너지를 이용한 더블토크 검출방법.In the method for detecting the starting point of the double talk is transmitted to the original guidance broadcast signal based on the control signal of the microcomputer 200, mixed with the user's voice signal and fed back, the frame ticker energy of the original announcement broadcast signal transmitted Calculating and storing in the memory 100, compensating the original guide broadcast signal and the user's voice signal fed back and input to the set small collection level, and calculating and storing the frame tigger energy in the memory 100; In the first step, the frame tigger energy of the original announcement broadcast signal stored in the memory 100 and the frame announcement energy of the user's voice signal are compared with the frame tigger energy of the original announcement broadcast signal stored in the memory 100. If the frame ticker energy of the original announcement signal and the user voice signal stored in the 100 is greater than the frame ticker energy of the original announcement signal stored in the memory 100, the starting point of the peak on the time axis corresponding to the difference. And a second step of detecting a as a starting point of the double torque. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
