It should be noted that the schematic structural diagram of the server is merely an example, and more or fewer components may be specifically included, which is not limited herein.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for synchronously screen-casting an explanation location of a presenter in a cloud conference scene according to an embodiment of the present application, where the method may be executed by a server, for example, 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 screen-casting an explanation location of a presenter in a cloud conference scene includes:
step S101, audio information of a speaker in the cloud conference is obtained.
The cloud conference and the speaker can refer to the foregoing description, and details are not repeated herein.
The server can acquire the audio equipment uploaded by the audio acquisition equipment of the speaker from the cloud space, and the audio acquisition equipment is used for acquiring the audio information of the speaker. The audio acquisition equipment can be the same equipment as the second local equipment of the speaker, and can also be different equipment from the second local equipment of the speaker.
And step S102, acquiring an explanation page corresponding to the audio information of the speaker.
The shared content and the explanation page can refer to the foregoing description, and are not described herein again.
The obtained explanation page corresponding to the audio information of the speaker may be an explanation page currently used by the speaker, that is, the speaker 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 obtained explanation page corresponding to the audio information of the speaker may also be a plurality of explanation pages corresponding to shared contents explained by the speaker. The specific number of the obtained explanation pages corresponding to the audio information of the speaker is not further limited, and can be set according to actual requirements.
In specific implementation, if it is monitored that the second local device of the speaker sends a page replacement instruction, the obtained explanation page is an explanation page after the replacement instruction is executed, and there is one explanation page corresponding to the audio information of the speaker obtained at this time. Or, when the shared content has a plurality of topics, before the explanation page is changed to the next topic, at least one explanation page corresponding to the next topic may be acquired, where the acquired explanation page corresponding to the audio information of the speaker includes at least one. Or, the explanation pages corresponding to the audio information of the speaker may be periodically obtained, for example, an explanation page may be obtained once after a preset time period elapses, where the duration of the preset time period may be set according to a requirement, and the explanation pages corresponding to the audio information of the speaker that are obtained at this time include at least one. The scheme does not further 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 speaker according to the audio information of the speaker 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 speaker from the cloud space, and the audio information used for determining the explanation position of the speaker is periodically acquired at the moment, so that the explanation position corresponding to the speaker can be continuously updated, and the accuracy of the explanation position of the determined speaker is ensured. The duration of the audio frequency obtained each time is the period duration, so that the content of the lecture of the speaker is not missed, and the reliability of the execution of the method is ensured.
And step S104, updating the page content of the explanation page according to the explanation position of the speaker.
Wherein the operation of updating the contents of the explanation page enables the contents corresponding to the determined position of the explanation by the speaker to be highlighted for the human eye to recognize.
In a specific implementation, if the content corresponding to the lecture position of the speaker is on the currently used lecture page, the executed operation of updating the content of the lecture page is: the content corresponding to the lecture position of the speaker is highlighted in the lecture page currently in use. If there are a plurality of acquired explanation pages corresponding to the audio information of the speaker and the content corresponding to the explanation position of the speaker is not on the currently used explanation page, the executed operation of updating the content of the explanation page is as follows: and highlighting the content corresponding to the explaining position of the speaker on the corresponding explaining page.
Step S105, sending the updated explanation page to the local equipment participating in the cloud conference.
The server can send the updated explanation page to the local device except the local device of the speaker, so that other conference participants who are not in the same space with the speaker can quickly locate the explanation position of the speaker through the updated explanation page displayed in the local device display interface. Or the server can send the updated explanation pages to the local devices of all the participants participating in the cloud conference, so that other people in the same space with the speaker can quickly locate the explanation position of the speaker through the updated explanation pages when the speaker does not indicate the explanation position.
It can be seen that the synchronous screen projection method and the related device for the speaker explanation position in the cloud conference scene described in this embodiment can obtain the audio information of the speaker in the cloud conference; acquiring an explanation page corresponding to the audio information of the speaker; determining the explaining position of the speaker according to the audio information of the speaker and the page content of the explaining page; updating the page content of the explanation page according to the explanation position of the speaker; and sending the updated explanation page to local equipment participating in the cloud conference. Therefore, the explanation page updated according to the explanation position of the main speaker obtained by determination can show the explanation position of the main speaker for the conference participants participating in the cloud conference, so that the conference participants can quickly position the explanation content of the main speaker in the explanation page, and the conference participants can be improved in conference experience. In addition, the operations such as the creation of the explanation page are completed on the server, and compared with the operations of the local device for collecting and uploading the video frames corresponding to the display content in real time, the data volume required to be processed by the local device is small, and the requirement on the configuration of the local device is low. Therefore, the scheme provided by the embodiment of the application has a wider application range.
In one possible example, the determining the lecture position of the speaker according to the audio information of the speaker and the page content of the lecture page includes: comparing the audio information of the speaker with first content in the page content of the explanation page to obtain a first comparison result; wherein, the explanation content of one explanation page comprises at least one first content; and determining the explaining position of the speaker 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 the content of a segment of text, the content of a sentence of text, the content of a line of text and the like; or, when the text information in the explanation page is distributed to form at least one area, one first content can also correspond to the content of the text in one area. 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 here, and may be specifically set according to requirements. It is understood that the explanation contents in other forms such as tables can be decomposed into corresponding text information or image information.
At least one first content included in the explanation content of one explanation page can be character information; or, the at least one first content included in the explanation content of one explanation page may be image information; or, when the explained contents of one explained page include 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 speaker may be compared with each of the first contents in sequence. Or the audio information of the speaker is compared with each first content synchronously, so that the efficiency is improved, and the time for determining the explanation position of the speaker is shortened.
In this example, in order to facilitate highlighting of the speaker explanation position, the first comparison result includes a smaller number of first contents than the number of first contents included in the explanation page. And 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, not updating the explanation page.
In this example, if the explanation page corresponding to the audio information of the speaker includes at least two first contents, the audio information of the speaker may be compared with each of the first contents, so as to obtain a first comparison result. The first comparison result may be that the lecture position of the presenter is one first content in the lecture page, or, when a plurality of first contents are included in the lecture page, the first comparison result may be that the lecture position of the presenter is at least two first contents in the lecture page. For example, if the explanation page corresponding to the audio information of the speaker includes at least two pieces of text information, one piece of text information may correspond to one first content. At this time, the audio information of the speaker can be compared with each segment of text information respectively, so as to obtain a first comparison result. The first comparison result can be that the speaker explanation position is the text information of a certain section in the explanation page; or, if the explanation page includes a plurality of sections of text information, the first comparison result may be that the explanation position of the speaker is at least two sections of text information in the explanation page. For example, if the explanation page includes content a, content B, and content C, the first comparison result may be that the content corresponding to the explanation position of the speaker is content a; alternatively, the first comparison result may be that the contents corresponding to the lecture position of the presenter are the a content and the C content. It can be understood that the content corresponding to the position of the speaker may be the whole text message of the first content corresponding to the first comparison result, or may be a certain sentence of text message or a certain phrase in the text message.
Therefore, the first content corresponding to the audio information of the speaker can be quickly positioned by comparing the audio information of the speaker with each first content in the explanation page, and the explanation position of the speaker is determined. Through the embodiment, the page content of the explained page can be divided into the plurality of first contents when the page content is more, so that the task amount of the server for single comparison is reduced, and the processing pressure of the server is relieved.
In one possible example, the page content of the explanation page includes at least two first contents; the comparing the audio information of the speaker with the first content in the page content of the explanation page includes: determining whether the at least two first contents comprise first contents with explained identifications, wherein the first contents with the explained identifications are first contents corresponding to historical explanation positions of a speaker; and if so, comparing the audio information of the speaker with the first content without the explained identification.
The first content with the explained identifier is the first content once confirmed as the explaining position of the speaker in the process of explaining the shared content by the speaker, that is, the first content confirmed as the explaining position of the speaker in the process of confirming the explaining position of the speaker historically, and can also be understood as the content already explained by the speaker.
In specific implementation, the server may set the explained identifier for the first content corresponding to the first comparison result after obtaining the first comparison result each time, so as to identify and classify when performing subsequent steps.
In a specific implementation, the server may determine whether there is a first content with an already explained identifier in the explained content of the explained page, and if not, may compare the audio information of the speaker with each first content. And if so, comparing the audio information of the speaker with each first content which is not set with the explained identification. At this time, if the comparison is successful, the speaker explaining position is a position corresponding to the first content which is successfully compared; and if the comparison fails, comparing the audio information of the speaker with the first content provided with the explained identifier.
It is understood that a speaker, when speaking, will typically speak one content after the next content is spoken. Therefore, the efficiency of obtaining the first comparison result can be improved by comparing the audio information of the speaker with the first content which is not described by the speaker, the time difference between the obtaining of the audio information of the speaker and the obtaining of the first comparison result is shortened, and the efficiency of determining the speaker explaining position is improved.
In one possible example, if the page content of the explanation page includes at least two first contents, the audio information of the speaker and the first contents adjacent to the explanation position of the speaker determined last time may be compared first, so as to shorten a time difference between obtaining the audio information of the speaker and obtaining the first comparison result, and improve accuracy of the explanation position of the determined speaker.
In one possible example, the determining the lecture position of the speaker according to the first comparison result includes: determining first content corresponding to the explanation position of the speaker 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 so, comparing the audio information of the speaker with second content to obtain a second comparison result, wherein the second content is content corresponding to the first content, and the first content comprises at least one second content; and determining the explaining position of the speaker 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; and if the first content comprises character information and image information, the second content is the character information or the image information. Illustratively, when the first content includes a plurality of text segments, a second content may correspond to the content of a text segment, the content of a sentence of text, the content of a line of text, or the like. When the first content includes only one 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 comprises at least two images, one second content may correspond to an independent image, or one 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 the number of paragraphs, the number of sentences, the number of texts, and the like. When the first content is image information, the third content may be a feature amount or the like. For example, if the first content is a text segment, the second content is a sentence, and the number of the third content may be the number of sentences in the text segment or the number of words in the text segment.
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 segment of words, the third content may be defined as a number of words, and the number of the third content is the number of words included in the first content, and the preset number may be N words.
In a specific implementation, if the number of the third contents is greater than the preset number, the audio information of the speaker needs to be further compared with each of the second contents. 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 explaining position of the speaker.
It is to be understood that the second contents may perform the steps in the above-described embodiments as the first contents when the audio information of the speaker is compared with the respective second contents.
Therefore, by adopting the scheme provided by the embodiment, the accuracy of the explaining position of the speaker can be improved, and the situation that the meeting participants cannot accurately find the position of the explaining content of the speaker due to excessive contents corresponding to the result of comparison only once can be avoided. The processing pressure of the server for single comparison can be avoided being reduced, and the performance requirement of the server for single comparison is lowered.
In one possible example, the 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 includes: analyzing the audio information of the speaker to obtain text data; if the first content is character information, matching the text data with the character 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; wherein the first content with the highest matching similarity is the speaker explanation position.
The method for analyzing the audio information of the speaker may be a method of converting voice into text or a method of semantic analysis, and is not further limited herein. Correspondingly, the text data can be a 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 speaker, and an analysis result included in the analysis text may be a sentence or a phrase, and the like.
The preset feature tag is a character tag which is correspondingly set by the server according to the image content.
