Description
Technical field
The present invention relates to online teaching fields, and in particular to a kind of method and system of more student side audio automatic mutes.
Background technique
With the popularity of the internet, the mode of network distance education is increasingly received by masses, is had become conventional complete
One of the important supplement form of day system education, and occur a large amount of Distance Teaching Platform therewith.Distance Teaching Platform is being undergone
After the development of more than ten years, various aspects function is all fairly perfect at present, in each school, educational institution, training organization
Play central role.But existing online teaching platform, it mutually mutually listens between multiple terminals, or loudspeaker is arranged
Mute, to shield other sound, this mode can no longer meet teaching demand.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of method of more student side audio automatic mutes, in multiple
When causing trouble while singing in unison a song and reading aloud, all student sides are automatically transmitted through other student sides the sound come and carry out automatic mute,
It can only hear that teacher end is transmitted through the sound come at this time, system restores what student side was mutually listened automatically after singing in unison a song and reading aloud
Function.With solve it is caused when multiple student sides sing in unison a song and read aloud interfere with each other, can not with reference to same rhythm carry out in unison
The problem of singing and reading aloud.Technical scheme is as follows:
As the first aspect of the present invention, a kind of method of more student side audio automatic mutes, which comprises

Row is played simultaneously, and other student terminal sound carry out automatic mute processing, i.e. it is next can only to hear that teacher's terminal is transmitted through for student terminal
Sound；
It sings in unison a song and bright read time if non-, then received sound real-time Transmission is synchronized to all terminals and broadcast
It puts.
Further, it is sung in unison a song and bright read time by current whether be in of voice signal judgement specifically: when
Sound waveform identical of received multiple voice signals or reach certain similarity simultaneously, then it is assumed that be currently at and sing in unison a song
With bright read time；When simultaneously received multiple voice signals sound waveform be lower than certain similarity, then it is assumed that be currently at non-
It sings in unison a song and bright read time.
Further, the method also includes if judgement is sent in singing in unison a song and bright read time to student terminal
It is currently at the information to sing in unison a song with bright read time.
Further, display is currently at the teacher's terminal mutually listened and institute on student terminal and the touch screen of teacher's terminal
There is the terminal number list of student terminal, student terminal and teacher's terminal can be arranged in respective terminal by the terminal number
Actively selection needs mute terminal to table, to shield the sound of the terminal.
As a second aspect of the invention, a kind of system of more student side audio automatic mutes is provided, the system comprises
Server, teacher's terminal and multiple student terminals；
The voice signal that the server is transmitted for real-time reception teacher terminal and student terminal, passes through the sound
Current whether be in of sound signal judgement sings in unison a song and bright read time；
If in singing in unison a song and bright read time；Then only by the voice signal real-time Transmission of teacher's terminal to student terminal into
Row is played simultaneously, and other student terminal sound carry out automatic mute processing, i.e. it is next can only to hear that teacher's terminal is transmitted through for student terminal
Sound；
It sings in unison a song and bright read time if non-, then received sound real-time Transmission is synchronized to all terminals and broadcast
It puts.
Further, the server includes audible signal reception module, judgment module and sound output module；
The audible signal reception module is used for for receiving the voice signal from teacher's terminal and student terminal；
Whether the judgment module is used to judge by the received voice signal of institute current in when singing in unison a song and reading aloud
Between, when sound waveform identical of received multiple voice signals simultaneously or reach certain similarity, then it is assumed that be currently at neat
Sound is sung and bright read time；When the sound waveform of received multiple voice signals simultaneously is lower than certain similarity, then it is assumed that current
It sings in unison a song and bright read time in non-.
The sound output module is used to received sound being output to other terminals, when judgment module judgement is currently at
It sings in unison a song and bright read time, then the voice signal real-time Transmission of teacher's terminal is only synchronized into broadcasting to student terminal；When
Judgment module judgement be currently at it is non-sing in unison a song and bright read time, then by received sound real-time Transmission to all terminals progress
It is played simultaneously.
Further, the server further includes condition prompting module, and the condition prompting module is used to sentence when server
