Problems solved by technology

[0002] In the conferencing system, the functions expected by the user are generally completed through the operation of the remote control, such as output volume adjustment, left and right movement of the function list and other operations. Through the operation of the remote control, not only the button functions are clear, but also the operation is simple and the cost is low. Low; but there are the following defects in the operation of the remote control: 1. When the remote control fails, it will affect the normal use of the conference function; 2. When there are many people who need to operate, it is inconvenient to pass the remote control, which affects the user experience
Of course, there are also more convenient ways in the prior art. For example, related operations can be realized through the touch screen, and more advanced ones can be realized through voice recognition. However, the cost of both touch screen and voice recognition is relatively high. Especially for the implementation of speech recognition, which requires a large number of sample training, the development cost is higher

specific Embodiment 1

[0033] Please refer to figure 1 As shown, a preferred embodiment of the method for tapping the microphone array to simulate button operation of the present invention, the method includes the following steps:

[0034] Step S1, setting the tap event start flag start and timer timer, and initializing the tap event start flag and timer, that is, start=0, timer=0;

[0035] Step S2, with 10ms data as the basic processing unit, read the collected data of the microphone, that is, only read the 10ms data of the microphone each time; since the duration of the general voice is greater than 10ms, the duration of the signal generated by tapping the microphone It is less than 10ms, so the 10ms data is used as the basic processing unit to read the collected data of the microphone and analyze the collected data.

[0036] Step S3, detect whether the read acquisition data (10ms data) satisfies the change characteristics of the knock signal, if it is satisfied, then enter step S4; if not, add '...

specific Embodiment 2

[0062] Please refer to figure 1 As shown, different from the specific embodiment one, in the specific embodiment two, the value of the reference value D1 is 0.5; the value of the fundamental frequency value D2 is 25 times / ms, and the value of the k The value is 0.2; the value of the duration T1 is 4s; the value of the maximum time interval T2 is 0.5s.

specific Embodiment 3

[0063] Please refer to figure 1 As shown, different from the specific embodiment one, in the specific embodiment three, the value of the reference value D1 is 0.8; the value of the fundamental frequency value D2 is 50 times / ms, and the value of the k The value is 0.4; the value of the duration T1 is 5s; the value of the maximum time interval T2 is 1s.

[0064] In summary, the present invention has the following advantages: 1. The operation expected by the user can be completed through simple microphone tapping detection, which can not only overcome the inconvenience caused by the need to pass the remote control or the failure of the remote control when multiple people operate in the past. , and has better functional scalability, and is particularly convenient to operate; 2. The desired function can be realized through the microphone required by the conference system itself, without additional hardware support, which can greatly reduce the cost.

Abstract

The invention provides a method for simulating key operation by tapping a microphone array. The method includes the following steps: S1, setting and initializing a tapping event start flag and a timer; S2, taking a 10 ms data as a basic processing unit, and reading collected data of a microphone; S3, detecting whether the collected data meets variation characteristics of a tapping signal or not, and if so, entering S4; if not, adding a '0' at the end of the data sequence, and entering S5; S4, calculating the zero-crossing rate of the collected data, judging whether the collected data is a tapping signal or not according to the zero-crossing rate, and if so, adding a '1' at the end of the data sequence; If not, adding a '0' at the end of the data sequence; S5, intercepting a complete tapping event; S6, searching a corresponding desired operation from the mapping list according to the intercepted tapping event, and performing the desired operation. According to the method for simulatingkey operation by tapping a microphone array, the function of completing the desired operation of users by tapping the microphone is achieved, and inconvenience caused by operation of the remote controller in the past can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of voice communication, in particular to a method for tapping a microphone array to simulate button operation. Background technique [0002] In the conferencing system, the functions expected by the user are generally completed through the operation of the remote control, such as output volume adjustment, left and right shifting of the function list, and other operations. Through the operation of the remote control, not only the key functions are clear, but also the operation is simple and the cost is low. Low; but there are the following defects in the operation of the remote control: 1. When the remote control fails, it will affect the normal use of the conference function; 2. When there are many people who need to operate, it is inconvenient to pass the remote control, which affects the user experience. Of course, there are also more convenient ways in the prior art.
