In particular implementations, the processor 110 is configured to perform any of the steps performed by the server in the method embodiments described below, and when performing a data transmission operation, such as sending an explanation page, the communication interface 130 may be selectively invoked to complete the corresponding operation.
It should be noted that the above-mentioned schematic structural diagram of the server is merely an example, and more or fewer devices may be specifically included, which is not limited only herein.
Referring to fig. 3, fig. 3 is a flowchart of a method for synchronously projecting a talker explanation position in a cloud conference scene according to an embodiment of the present application, where the method may be executed by a server, and the method may be applied to the server 100 shown in fig. 1 or fig. 2, and as shown in fig. 3, the method for synchronously projecting a talker explanation position in a cloud conference scene includes:
step S101, audio information of a speaker in a cloud conference is acquired.
The cloud conference and the presenter refer to the foregoing description, and are not described herein.
The server can acquire the audio equipment uploaded by the audio acquisition equipment of the speaker from the cloud space, wherein the audio acquisition equipment is used for acquiring the audio information of the speaker. The audio acquisition device may be the same device as the second local device of the presenter, or may be a different device from the second local device of the presenter.
Step S102, acquiring an explanation page corresponding to the audio information of the presenter.
The shared content and the explanation page may refer to the foregoing description, and are not described herein.
The explanation page corresponding to the audio information of the presenter can be an explanation page currently used by the presenter, that is, the presenter controls the cloud conference through the second local device to stay on the explanation page in the display interface of the second local device. The explanation page corresponding to the audio information of the presenter may be a plurality of explanation pages corresponding to the shared content taught by the presenter. The specific number of the explanation pages corresponding to the audio information of the presenter is not further limited, and can be set according to actual requirements.
In a specific implementation, if the obtained explanation page is the explanation page after the replacement instruction is executed when the fact that the second local equipment of the presenter sends the page replacement instruction is monitored, one explanation page corresponding to the audio information of the presenter is obtained at the moment. Or when the shared content has a plurality of topics, at least one explanation page corresponding to the next topic may be acquired before the explanation page is replaced with the next topic, and at this time, the acquired explanation page corresponding to the audio information of the presenter includes at least one explanation page. Or, the explanation page corresponding to the audio information of the presenter may be periodically acquired, for example, the explanation page may be acquired once after a preset period of time passes, where the duration of the preset period of time may be set according to the requirement, and at this time, the acquired explanation page corresponding to the audio information of the presenter includes at least one explanation page. The scheme does not limit the specific form of the explanation page, and can be set according to actual requirements.
And step S103, determining the explanation position of the presenter according to the audio information of the presenter and the page content of the explanation page.
In the specific implementation, the server can periodically acquire the audio information uploaded by the audio acquisition equipment of the presenter from the cloud space, and the audio information used for determining the presenter explanation position is the periodically acquired audio information, so that the corresponding explanation position of the presenter can be continuously updated, and the accuracy of the determined presenter explanation position is ensured. The audio time length obtained each time is the period time length, so that the content taught by the speaker is not missed, and the execution reliability of the method is ensured.
And step S104, updating page contents of the explanation page according to the explanation position of the presenter.
The operation of updating the content of the explanation page can enable the content corresponding to the explanation position of the determined main speaker to be highlighted so as to be convenient for human eyes to recognize.
In a specific implementation, if the content corresponding to the lecture position of the presenter is in the currently used lecture page, the operation of updating the content of the lecture page is performed as follows: content corresponding to the presenter's lecture position is highlighted within the lecture page currently in use. If there are a plurality of explanation pages corresponding to the audio information of the presenter, and the content corresponding to the presenter explanation position is not currently in use, the operation of updating the content of the explanation page is performed as follows: content corresponding to the presenter's explanation position is highlighted on the corresponding explanation page.
Step S105, the updated explanation page is sent to the local equipment participating in the cloud conference.
The server can send the updated explanation page to local equipment other than the local equipment of the presenter, so that other conference participants who are not in the same space with the presenter can quickly locate the presenter explanation position through the updated explanation page displayed in the local equipment display interface. Or, the server may send the updated explanation page to the local devices of all the participants participating in the cloud conference, so that when the presenter does not indicate the explanation position, other people in the same space with the presenter can quickly locate the presenter's explanation position through the updated explanation page.
It can be seen that, the synchronous screen projection method and the related device for the explanation position of the presenter in the cloud conference scene described in the embodiment can acquire the audio information of the presenter in the cloud conference; acquiring an explanation page corresponding to the audio information of the speaker; determining the explanation position of the main speaker according to the audio information of the main speaker and the page content of the explanation page; according to the explanation position of the speaker, updating page content of the explanation page; and sending the updated explanation page to the local equipment participating in the cloud conference. Therefore, according to the explanation page with updated explanation positions of the main talkers, the explanation positions of the main talkers can be displayed to the conference participants participating in the cloud conference, so that the conference participants can quickly locate the explanation contents of the main talkers in the explanation page, and the participation experience of the conference participants can be improved. In addition, the operations such as explanation page creation are completed in the server, and compared with the operations such as the real-time acquisition and uploading of video frames corresponding to display contents by the local equipment, the method has the advantages that the data size required to be processed by the local equipment is smaller, and the configuration requirement on the local equipment is lower. Therefore, the scheme provided by the embodiment of the application has wider application range.
In one possible example, the determining the lecturer location according to the audio information of the lecturer and the page content of the lecture page includes: comparing the audio information of the speaker with the first content in the page content of the explanation page to obtain a first comparison result; the explanation content of one explanation page comprises at least one first content; and determining the explanation position of the presenter according to the first comparison result.
The first content may be text information or image information. When the first content is text information, one first content can correspond to one text content, one sentence text content, one line text content or the like; alternatively, when the text information in the explanation page is distributed to form at least one region, one first content may also correspond to the text content of one region. When the first content is image information, a first content may correspond to an independent image, or a first content may correspond to a content of a certain area in an image or a certain feature in an image. The specific form of the first content is not further limited herein, and may be specifically set according to the need. It will be appreciated that other forms of instructional content, such as forms, may be broken down into corresponding textual or graphical information.
The explanation content of one explanation page comprises at least one first content which can be text information; alternatively, the at least one first content included in the explanation content of one explanation page may be image information; alternatively, when the explanation content of one explanation page includes at least two first contents, the at least two first contents may include both text information and image information.
In a specific implementation, the audio information of the presenter may be compared with each of the first contents in sequence. Or the audio information of the main speaker is synchronously compared with each first content, so that the efficiency is improved, and the determination time of the explanation position of the main speaker is shortened.
In this example, in order to facilitate highlighting of the presenter's explanation position, the first comparison includes a number of first contents smaller than the number of first contents included in the explanation page. If the number of the first contents included in the first comparison result is equal to the number of the first contents included in the explanation page, the explanation page is not updated.
In this example, if at least two first contents are included in the explanation page corresponding to the audio information of the presenter, the audio information of the presenter may be compared with each first content, respectively, to obtain a first comparison result. The first comparison result may be one first content in the lecture page for the lecturer lecture position, or when a plurality of first contents are included in the lecture page, the first comparison result may be at least two first contents in the lecture page for the lecturer lecture position. For example, if at least two pieces of text information are included in the explanation page corresponding to the audio information of the presenter, one piece of text information may correspond to one first content. At this time, the audio information of the presenter can be compared with each piece of text information, respectively, so as to obtain a first comparison result. The first comparison result can be text information of a section in the explanation page at the explanation position of the presenter; or, if the explanation page includes multiple pieces of text information, the first comparison result may be that the explanation position of the presenter is at least two pieces of text information in the explanation page. For example, if the explanation page includes a content a, a content B, and a content C, the first comparison result may be that the content corresponding to the explanation position of the presenter is the content a; alternatively, the first comparison result may be that contents corresponding to the lecturer explanation position are a content and C content. It can be understood that the content corresponding to the explanation position of the presenter may be the whole text information of the first content corresponding to the first comparison result, or may be a text information or a phrase in the text information.
Therefore, the first content corresponding to the audio information of the presenter can be rapidly positioned by comparing the audio information of the presenter with the first content in the explanation page, and the explanation position of the presenter is determined. According to the embodiment, the explanation page can be divided into a plurality of first contents when the page contents are more, so that the task amount of single comparison of the server is reduced, and the processing pressure of the server is reduced.
In one possible example, the page content of the explanation page includes at least two first contents; the comparing the audio information of the presenter with the first content in the page content of the explanation page includes: determining whether the at least two first contents comprise first contents provided with explanation marks, wherein the first contents provided with the explanation marks refer to first contents corresponding to the historic explanation positions of the main speaker; and if so, comparing the audio information of the speaker with the first content which is not provided with the explained mark.
The first content provided with the explanation mark refers to the first content which is confirmed to be the explanation position of the presenter in the process of explaining the shared content by the presenter, namely the first content which is confirmed to be the explanation position of the presenter in the process of historically confirming the explanation position of the presenter, and can also be understood to be the content which is already taught by the presenter.
In particular, after each time the first comparison result is obtained, the server may set the interpreted identifier for the first content corresponding to the first comparison result, so as to identify classification when performing the subsequent steps.
In a specific implementation, the server may determine whether the first content with the explanation identifier set in the explanation content of the explanation page first, and if not, compare the audio information of the presenter with each first content. If so, the audio information of the presenter is compared with each first content which is not set with the explanation identification. At this time, if the comparison is successful, the presenter explains that the position is the position corresponding to the first content that the comparison is successful; if the comparison fails, the audio information of the speaker is compared with the first content provided with the explained identification.
It will be appreciated that a presenter will typically speak one content after the next content is spoken. Therefore, by comparing the audio information of the presenter with the first content which is not taught by the presenter, the efficiency of obtaining the first comparison result can be improved, the time difference between obtaining the audio information of the presenter and obtaining the first comparison result can be shortened, and the efficiency of determining the teaching position of the presenter can be improved.
In one possible example, if the page content of the explanation page includes at least two first contents, the audio information of the presenter and the first contents adjacent to the presenter explanation position determined last time may be compared first, so as to shorten the time difference between obtaining the audio information of the presenter and obtaining the first comparison result, and improve the accuracy of the determined presenter explanation position.
In one possible example, the determining the presenter explanation location according to the first comparison result includes: determining first content corresponding to the explanation position of the presenter according to the first comparison result; judging whether the number of third contents is larger than a preset number, wherein the third contents are contents corresponding to the first contents, and the first contents comprise at least one third content; if yes, comparing the audio information of the speaker with second content to obtain a second comparison result, wherein the second content is corresponding to the first content, and the first content comprises at least one second content; and determining the explanation position of the presenter according to the second comparison result.
If the first content only comprises text information, the second content is the text information; if the first content only comprises image information, the second content is the image information; if the first content includes text information and image information, the second content is text information or image information. For example, when the first content includes a plurality of pieces of text, one second content may correspond to one piece of text content, one sentence of text content, one line of text content, or the like. When the first content includes only a piece of text, one second content may correspond to the content of one sentence of text, the content of one line of text, or the like. When the first content includes at least two images, a second content may correspond to an independent image, or a second content may correspond to the content of a certain area in an image or a certain feature in an image.
When the first content is text information, the number of the third content may be paragraph number, sentence number, text number, etc. When the first content is image information, the third content may be the feature quantity or the like. For example, if the first content is a text content, the second content is a sentence content, and the number of third content may be the number of sentences in the text, or the number of words in the text.
The preset number may be one, two or more, and may be specifically set according to actual requirements, which is not specifically limited herein. For example, when the first content is a piece of text, the third content may be defined as the number of words, where the number of the third content is the number of words included in the first content, and the preset number may be N number of words.
In a specific implementation, if the number of the third contents is greater than the preset number, the audio information of the presenter needs to be further compared with each second content. And if the number of the third contents is smaller than the preset number, taking the first contents corresponding to the first comparison result as the finally determined explanation positions of the presenter.
It will be appreciated that the second content may perform the steps of the above embodiments as the first content when audio information of the presenter is compared with the respective second content.
Therefore, by adopting the scheme provided by the embodiment, the accuracy of the explanation position of the presenter can be improved, and the situation that the conference participants cannot accurately find the position of the explanation content of the presenter due to excessive content corresponding to the result of only one comparison can be avoided. The processing pressure of single comparison of the server can be avoided from being reduced, and the performance requirement on single comparison of the server is reduced.
In one possible example, the comparing the audio information of the presenter and the first content in the page content of the explanation page to obtain a first comparison result includes: analyzing the audio information of the speaker to obtain text data; if the first content is text information, matching the text data with the text information to obtain matching similarity; if the first content is image information, matching the text data with a preset feature tag of the image information to obtain matching similarity; comparing the matching similarity of all the first contents to obtain the first content with the highest matching similarity; the first content with the highest matching similarity is the lecturer explanation position.
The manner of parsing the audio information of the speaker may be a manner of converting voice into text or a manner of semantic parsing, which is not limited herein. Correspondingly, the text data can be text obtained by directly converting the audio information of the speaker; or, the text data may be an analysis text obtained by performing semantic analysis on the audio information of the presenter, and the analysis result included in the analysis text may be a sentence or a phrase.
The preset feature labels are text labels correspondingly set by the server according to the image content.
