Description
Technical field
The present invention relates to video conferencing systems, and in particular to a kind of intelligence system about video conference.
Background technique
Video conference will appear more people when carrying out while talk or network break-off phenomenon, cause in the another of video conference
It does not hear at end, it is necessary to raise an objection, speaker is allowed to retell；It not only wastes time also to be easy to interrupt sb's train of tought in this way；So we need
Want a kind of video conferencing system with subtitle
The development of Video Conference System is getting faster simultaneously, while more and more company and government departments all start
Using Video Conference System, to improve working efficiency.Voice and video such as based on meeting is run in corporate networks
A main problem being faced of multimedia application be how to manage the echo eliminated in meeting.
Summary of the invention
The technical problem to be solved by the present invention is to video conference progress when will appear more people and meanwhile talk or network suspend
Phenomenon causes not hearing in the other end of video conference, it is necessary to raise an objection, speaker is allowed to retell；It not only wastes time in this way
Also it is easy to interrupt sb's train of tought and eliminates echo, and it is an object of the present invention to provide a kind of intelligence system about video conference, solves video council
View will appear more people when carrying out while talk or network break-off phenomenon, cause not hearing in the other end of video conference, it is necessary to mention
Objection out allows speaker to retell；It not only wastes time also to be easy the problem of interrupting sb's train of tought and eliminating echo in this way.
The present invention is achieved through the following technical solutions:
A kind of intelligence system about video conference, including multiple microphone modules, the microphone module pass through CAN bus
It is connect with microphone switch module；Each microphone module connects an audio frequency vibration module and a speech detection module；It is described
Speech detection module: detecting the voice messaging of microphone module, is sent to SIP control centre；The audio frequency vibration module: detection words
The audio frequency vibration information of cylinder mould block, is sent to SIP control centre；The SIP control centre: the voice of speech detection module is received
Information is compared with database, and whether the speech information content includes default voice X, including when default voice X, sends and close
Microphone is instructed to microphone switch module；The microphone switch module, which receives, to be instructed and closes corresponding microphone module, is continued to
The vibration information that audio frequency vibration module is sent sends and opens microphone instruction to microphone switch module, and the microphone switch module connects
It receives open command and opens corresponding microphone module；When not including default voice X, speech detection module information is continued to, and
The vibration information of audio frequency vibration module is not received；The SIP control centre: the voice messaging of speech detection module is received, simultaneously
It is sent to echo cancellation module and tone color identification module；The echo cancellation module receives voice messaging and eliminates echo, sends
Voice messaging after eliminating echo is to adaptive-filtering module；The adaptive-filtering module: the language of echo cancellation module is received
Message breath, is sent to TTS module after filtering processing；The TTS module receives filtering voice information, and voice messaging is converted to text
Word information, is sent to display module；The tone color identification module: the voice messaging that SIP control module is sent is received, and identifies sound
Color sends timbre information to control panel；The control panel receives the timbre information that tone color identification module is sent, and matches tone color
Color value sends colouring information to display module；The display module: while receiving the text information of TTS transmission, control panel
The colouring information of transmission；And display color text information.The present invention eliminates echo from microphone part, in existing video conference
In, each microphone is the state for unlatching, brings two problems in this way, and first is multi-faceted while when speaking, and can be led
Cause the people of the meeting other end that can hear, second is multi-faceted while speaking and increase noise and echo, and the present invention is in order to solve this
One problem, uses, and microphone is uniformly controlled switch, is controlled by CAN bus, sets inside each microphone module first
A speech detection module and audio frequency vibration module are set, for SIP control centre, first receives the information of speech detection module, when
When detecting default voice X, out code is sent, carries out unlatching microphone in the information sent by the audio frequency vibration module received
Module, only one microphone module is opened in the whole process, avoids the deficiency of traditional problem in this way.Preset X voice
It can be " I speech finish " " ask the visitor in next bit " etc., this specific content can be arbitrarily arranged；Present invention employs
Microphone holder installs speech transducer, collects voice messaging and carries out noise reduction, issues the conversion of TTS module voice, sends tone color and knows
Other module identifies tone color, and in pre-set database, control panel obtains the corresponding color value of tone color, text and color knot
The form of conjunction is shown on the display module；The following benefit of institute in this way, first corresponds to different tone colors by different colors,
It more intuitive can see conference content, second, save the time of meeting, it is unclear that or the personnel of meeting are not participated in,
Conference content, third, the quality of network not since can have been obtained by the combination of image and text.
The display module includes figure photo frame and textbox.Further, as a preferred solution of the present invention.
The control panel, including tamber data library and color-match library；Each tone color pair in the tamber data library
Answer a color in color-match library.Further, as a preferred solution of the present invention, so the tone color of meeting personnel all shifts to an earlier date
It records.
The microphone module is connected by relay module with CAN bus.Further, as a preferred solution of the present invention.
The SIP control centre receives first audio frequency vibration information by the sequence that audio frequency vibration module sends information, into
One step, as a preferred solution of the present invention.
Compared with prior art, the present invention having the following advantages and benefits:
1, a kind of intelligence system about video conference of the present invention, different tone colors is corresponded to by different colors, can be with
It is more intuitive to see conference content, save the time of meeting, it is unclear that or the personnel of meeting are not participated in, image can be passed through
Combination with text obtains conference content；
2, a kind of intelligence system about video conference of the present invention, microphone are uniformly controlled switch, are controlled by CAN bus
System, is arranged a speech detection module and audio frequency vibration module inside each microphone module first, in SIP control
The heart first receives the information of speech detection module, when detecting default voice X, out code is sent, in the audio by receiving
The information that shock module is sent carries out unlatching microphone module, only one microphone module is opened in the whole process, thus keeps away
The deficiency of traditional problem is exempted from；
3, a kind of intelligence system about video conference of the present invention, microphone module are connected by relay module and CAN bus
It connects, better switch control, the relay reaction time is rapid, and the unlatching of microphone can be carried out in the case where not stopping.
