The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present invention. A, B, C, D in the figure, in the free mode, when A, B, C, D four users speak simultaneously, there are four superimposed sounds, which results in noisy speech environment, and the sound output by the speaker cannot be heard clearly, resulting in poor video conference quality.
Referring to fig. 2, which is a schematic flowchart of a video conference data synchronization method according to an embodiment of the present invention, an execution subject of the method shown in fig. 2 may be a software and/or hardware device. The execution subject of the present application may include, but is not limited to, at least one of: user equipment, network equipment, etc. The user equipment may include, but is not limited to, a computer, a smart phone, a Personal Digital Assistant (PDA), the above mentioned electronic equipment, and the like. The network device may include, but is not limited to, a single network server, a server group of multiple network servers, or a cloud of numerous computers or network servers based on cloud computing, wherein cloud computing is one type of distributed computing, a super virtual computer consisting of a cluster of loosely coupled computers. The present embodiment does not limit this. The method comprises the following steps of S101 to S103:
s101, acquiring trigger time of a plurality of user side microphones in real time, acquiring a first user side based on the trigger time, and taking the rest user sides as second user sides, wherein the trigger time of the first user side is earlier than that of the second user side.
Specifically, the server detects the trigger time of a plurality of client microphones in real time, that is, when a user speaks through a client, the client collects information, wherein the collection time includes the trigger time, and then the client is divided into a first client and a second client by using the trigger time.
For example, A, B, C, D four users are in a video conference, the speaking time of the a user side is 10 o ' clock 10 min 01 sec, the speaking time of the B user side is 10 o ' clock 10 min 02 sec, the speaking time of the C user side is 10 o ' clock 10 min 03 sec, the speaking time of the D user side is 10 o ' clock 10 min 04 sec, and the corresponding trigger time is collected, since the speaking time of the a user side is 10 o ' clock 10 min 01 sec earlier than that of the other user sides, the a user side is taken as the first user side, and the rest (B, C, D) is taken as the second user side.
In practical applications, before acquiring the trigger times of the microphones of the plurality of user terminals in real time and acquiring the first user terminal based on the plurality of trigger times, the method further includes: and determining that the number of triggered user side microphones is greater than a preset number. It can be understood that if only one user speaks, the method of the present invention is not needed, and if more than one user speaks, the voice environment is noisy, and the method of the present invention can be used to improve the voice environment.
S102, acquiring first voice information acquired by the first user side, and sending the first voice information to the first user side and the second user side for playing processing.
Specifically, after the user terminals are classified, the sound of the first user terminal is sent to each user terminal, and is played by using the speakers of each user terminal, it can be understood that each user terminal can only hear the speaking sound of the first user terminal.
In practical application, noise analysis may be performed on the first voice information, and if the first voice information is noise information, the microphone of the first user end is turned off. It will be appreciated that if the first user terminal has the earliest trigger time, but it is always noise, such as current sound or other sounds, it needs to be shielded to avoid that it always occupies the resources of the first user terminal.
In some embodiments, the noise may also be determined by using voiceprints, for example, each user terminal may match a voiceprint feature in advance, then perform recognition processing on the voiceprint features collected by the user terminal, compare the processing results, and if the voiceprint features are not consistent, determine that the sound collected by the user terminal is noise.
S103, acquiring second voice information acquired by the second user side for conversion processing, generating text information, and sending the text information to the first user side and the second user side for display.
Specifically, referring to fig. 3, when recognizing that the second user speaks, the server does not play the sound of the second user, but converts the sound into text information to be displayed to the other user, and the other user can also know the content that the user needs to express through the text information.
In some embodiments, the textual information may be presented at a position below the corresponding video frame. In practical applications, after the text message is sent to the first user side and the second user side for display, the text message may be modified based on an editing operation of the second user side. It is understood that the user may modify the text message when the user finds that the text message is converted incorrectly.
In the embodiment, the voice of the earliest speaking user side is played and processed by collecting the speaking time of the plurality of user sides, and the rest of the voices of the speaking user sides are converted into the word processing, namely, when a plurality of persons speak at the same time, the voice of the earliest speaker is only played, so that the superposition of the voices is avoided, and the voice environment during the video conference is improved.
On the basis of the embodiment, in order to make the sound state of each user clear between users, the video frame corresponding to each user side is obtained, and the background of the video frame is processed based on different colors to generate the state frame; where green represents the user's voice playing, yellow represents the user is in a muted state, and red represents the user is speaking but not playing.
It can be understood that the sound state can be judged between users through the color of the background of the video frame, namely, the filter is added to the background of the video frame according to the preset conditions, and then the operations such as modest conversation and the like can be performed, so that the experience of the video conference of the users is improved.
In order to facilitate management of the video conference, the scheme further includes, before the triggering time of the microphones of the plurality of user terminals is collected in real time: receiving the setting of the priority of each user side, and giving authority to each user side based on the priority, wherein the priority comprises a first priority and a second priority;
it can be understood that different permissions can be issued to different user terminals according to the content of the conference, for example, the conference is dominated by a design department, and then the user terminals of the design department can be given a first priority, and the other user terminals can be given a second priority, wherein the permission level of the first priority is higher than the permission level of the second priority.
After the acquiring the first user end based on the plurality of trigger times, further comprising: and receiving an interruption request of the user terminal with a first priority, and closing a microphone of the first user terminal.
It will be appreciated that the first priority user terminal may interrupt the first user terminal, for example, an interrupt button on the user terminal may be clicked to generate an interrupt request, and the microphone of the first user terminal may be turned off.
In some embodiments, after said acquiring the first user end based on the plurality of trigger times, further comprises: receiving multiple types of operation requests of the user side with multiple second priorities, and generating a predicted value based on a preset rule, wherein the multiple types of operation requests comprise a content supplement request, a content error correction request and a content question request; and closing the microphone of the first user terminal based on a preset value and the predicted value.
It can be understood that, during a conference, a presenter continuously explains, in the process, situations that some users need to supplement content, or feel that the content is wrong, or have a question for the content, and the like occur, if the situations cannot be fed back in time, the quality of the video conference is poor, and when the user side with the first priority finds the situations, the user side with the first priority can interrupt due to high authority, whereas the user side with the second priority has low authority and cannot directly interrupt.
Wherein, the preset rule comprises:
N=0.2x+0.5y+0.3z
wherein, N represents the predicted value, x represents the number of the content supplementary requests sent by the user side with the second priority, y represents the number of the content error correction requests sent by the user side with the second priority, and z represents the number of the content query requests sent by the user side with the second priority.
It can be understood that, the number of content error correction requests sent by the user side in the second priority is weighted more heavily, because the importance of the content error correction requests is higher than the other two, the importance of the content error correction requests can also be adjusted according to actual situations.
Illustratively, x is 5, y is 6, z is 5, the obtained N value is 5.5, and if the preset value is 3, the microphone of the first user end needs to be turned off for interruption.
In order to more intuitively show the number of people with each type of request, after the receiving multiple types of operation requests of the multiple second priorities at the user side, the method further includes: and displaying the number of the content supplement requests sent by the user side with the second priority, the number of the content error correction requests sent by the user side with the second priority and the change of the number of the content question requests sent by the user side with the second priority along with the time on the basis of a preset curve model. Referring to fig. 4, the vertical coordinate represents the number, and the horizontal coordinate represents the time, so that the effect of the speech can be intuitively perceived through a curve.
In other embodiments, the presentation can also be visually displayed in the form of a histogram, and the presenter can perceive the presentation effect of the presenter through a visual chart, so as to interact with the user side in time or change the presentation style of the presenter in time.
