detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided to provide a more thorough The disclosure is to be understood, and the scope of the present disclosure can be fully conveyed to those skilled in the art.

1 is a flow chart showing the steps of an embodiment of a method for creating a presentation according to an embodiment of the present application. Specifically, the method may include the following steps:

Step 101: Load a web page generated for the presentation.

In the embodiment of the present application, the user can log in to the server by using a user account on a client such as a browser, and send a request for generating a presentation to the server.

If the server receives the build request sent by the client, it can configure a new presentation and configure the presentation with a unique presentation identifier, such as slide_id (slide ID), which is used to generate a unique one for the presentation. Edit the URL (Uniform Resource Locator) and return the URL for editing to the client.

For example, if the slide_id of a presentation ID is abcd1234, the URL that can be generated for editing is https://ppt.***.com/editor? Slide_id=abcd1234, where "***" is the domain name of the server.

The client accesses the URL for editing to load a web page, which is the carrier of the presentation, ie the presentation can edit the content in the web page.

Of course, if the presentation has been generated in the first place, the information of the presentation can be displayed in the area such as the user center. After the user clicks, the client can directly load the web page by using the URL for editing, which is not used in the embodiment of the present application. limit.

In addition, when the presentation is edited, the presentation ID is used to generate a unique URL for the presentation, and the URL for the presentation is returned to the client.

For example, if the slide_id of a presentation ID is abcd1234, the URL for editing can be generated as http://ppt.***.com/present? Slide_id=abcd1234#/, where "***" is the domain name of the server.

The client can access the URL for the presentation to load the web page, which is the carrier of the presentation, ie the presentation can be played in the web page.

Step 102, configuring a presentation element in the web page.

There are one or more web operation controls in the web page, and the user can trigger the web operation control by means of a mouse click or the like to add a presentation element.

In one example, as shown in FIG. 2A, the presentation elements can include one or more of the following:

Text, images, images of specified shapes, lines, tables, frames, and code.

In the web page, you can directly manipulate these presentation elements, edit some of the element parameters, for example, adjust the font's text box, image, image, line, table frame, code, etc. The size of the presentation element in the web page, rotate the font Presentation elements such as text boxes, images, images, lines, table frames, code, etc., dragging text boxes, images, images, lines, table frames, code, etc. of the presentation elements in the position of the web page, text in the text Enter text in presentation elements such as boxes, tables, and more.

In addition, the user can trigger the presentation element to edit state by clicking or the like. At this time, the editing operation bar of the presentation element is popped up in the web page, and the user can display the element of the presentation element in the editing operation column. Parameters for the user to adjust.

For example, as shown in FIG. 2B, if a text box of text is inserted in a web page, if the user clicks on the text box, the edit operation bar of the text box can be popped up in the web page, and the user can set the font alignment and font. Play multiplier, font color, line spacing, font spacing and other element parameters.

For another example, as shown in FIG. 2C, if a form is inserted in the web page, if the user clicks on the form, the edit operation column of the table may be popped up in the web page, and the user may set the number of rows, the number of columns, and the cell. Element parameters such as margins, border width, and border color.

It should be noted that these element parameters may be the same as or different from the types of editing that can be directly performed on the presentation elements, and the embodiment of the present application does not limit this.

For the editing of the presentation element configuration, the user can save it manually, or the script of the client executing the web page can be automatically saved. The parameters configured in the presentation element of the web page can be synchronized with the server during saving, and the server takes the parameter. Store under the presentation (represented by the presentation ID) for subsequent loading.

Of course, if the presentation has been generated before, the information of the presentation can be displayed in the user center and the like area. After the user clicks, the client loads the web page with the URL for editing, and according to the previously set element parameters. Load the appropriate presentation element for the user to proceed Line editing, this embodiment of the application does not limit this.

Step 103, adding audio data to the presentation element on a time axis to synchronously play the audio data when the presentation element is played according to the time axis.

In the embodiment of the present application, in order to control the playing of the presentation, the client can configure a timeline and set the playing time of the presentation element on the timeline.

In addition, the user can record audio data, and the client adds audio data to the presentation element, such as a user's speech, so that the presentation elements can be played while the audio data is being played on the time axis, so that the two can be synchronized.

In the editing state, as shown in FIG. 3A, FIG. 3B, FIG. 3C, and FIG. 3D, the user can set the playing time of the presentation element. With the passage of time, when the audio data is set to be played, the speech can be set to be switched in order. The manuscript elements, that is, the text "Quiet Night Thinking", "Li Bai", "Before the Moon".

In the speech state, as shown in FIG. 4A, FIG. 4B, FIG. 4C, and FIG. 4D, the timing control is displayed in the lower left corner, and as time passes, the audio presentation data is played, and the presentation document elements are switched in order, that is, the text is displayed. "Quiet night thinking", "Li Bai", "before the bed bright moonlight".

In an embodiment of the present application, step 103 may include the following sub-steps:

Sub-step S11, the recorder is called to record audio data to the presentation element.

In the embodiment of the present application, if the terminal where the client is located is configured with a microphone, the microphone can be called to collect the original audio data, and the recorder is called to record the audio data.

For example, as shown in FIG. 5A and FIG. 5B, in a web page, a recording control can be loaded, after clicking the recording control, recording is started, and a visual element of the audio data is displayed on the axis element of the visual axis of the time axis. .

In an example of an embodiment of the present application, the sub-step S11 may include the following sub-steps:

Sub-step S111, acquiring original audio stream data collected by the microphone;

Sub-step S112, the original audio stream data is transmitted to the recorder;

Sub-step S113, the original audio stream data is visualized in the recorder according to the recording parameters, and the original audio stream data is converted into audio data of a specified format.

In this example, the client can pass WebRTC (Web Real-Time Communication, The getUserMedia interface provided by the webpage real-time communication) acquires the original audio stream data collected by the microphone.

Create an audio stream source node through the createMediaStreamSource method of the Web Programming API (Application Programming Interface), and pass the audio source to the Recorder Recorder for initialization of the recorder.

In the recorder, a script processing node is created by the createScriptProcess method of the Web Audio API, which is used to process raw audio stream data using Javascript.

In addition, the audio source node is connected to the processing node, and the processing node is connected to the audio output node to form a complete processing flow.

The processing node can listen to the AudioProcessingEvent event through the onaudioprocess method, and the event acquires a certain length of data from the original audio stream data for processing at regular intervals.

When you start recording, pass the recording-related parameters (such as the starting position, the size of the selection, and the remaining width to the right of the selection) to the Web Worker, and notify onaudioprocess for audio processing.

After the parameters are set, in the onaudioprocess, the original audio stream data is visualized by the drawAudioWave method (the visualized elements are generated based on the frequency, waveform and other attributes of the original audio stream data), and the audio data is transmitted to the Web Worker for audio. Temporary and preliminary processing.

When the recording is paused, the audio processing is paused, and a format file such as WAV is requested from the Web Worker, and the Web Worker converts the existing original audio stream data into audio data of a format such as WAV and returns it.

In this example, since the computing power of the client (such as a browser) is mostly limited, and the temporary storage and processing of the original audio stream data generally requires a large amount of computing power, another thread is opened by introducing a Web Worker. The temporary storage and processing of the original audio stream data is performed to ensure that other processing of the client (such as a browser) can be performed normally.

In another embodiment of the present application, step 103 may include the following sub-steps:

Sub-step S21, inputting text information to the presentation element;

Sub-step S22, converting the text information into audio data.

In the embodiment of the present application, if the terminal where the client is located is not configured with a microphone, the user can input text information to the presentation element, which can be synthesized by voice (The Emperor Waltz, TEW) Converts text information to audio data.

Speech synthesis, also known as Text to Speech (TTS) technology, can usually include the following:

(1) Text analysis

Perform linguistic analysis on the input text information (simulating human understanding of natural language), lexical, grammatical and semantic analysis step by sentence to determine the low-level structure of the sentence and the composition of the phoneme of each word, including text Breaking sentences, word segmentation, processing of multi-syllable words, processing of numbers, processing of abbreviations, etc. Make the computer fully understand the input text and give the various pronunciation prompts needed in the last two parts.

(2) Prosody modeling

For the synthesis of speech, the characteristics of the segment, such as pitch, length and intensity, are made, so that the synthesized speech can correctly express the semantics and sound more natural.

(3) Speech synthesis (core module)

According to the result of prosody modeling, the phonetic primitives of the single words or phrases corresponding to the processed text are extracted from the speech synthesis library, and the prosody characteristics of the speech primitives are adjusted and modified by using a specific speech synthesis technique, and finally synthesized. Meet the required voice data.

Of course, the manner of adding audio data is only an example. In the implementation of the embodiment of the present application, other manners of adding audio data may be set according to actual conditions, for example, directly importing existing audio data, and the like. This is not limited. In addition, in addition to the above-mentioned judging processing method, those skilled in the art may also adopt other manners of adding audio data according to actual needs, and the embodiment of the present application does not limit this.

In the embodiment of the present application, when the addition of the audio data is completed, the audio data on the time axis can be uploaded to the server.

In the specific implementation, for recording audio data, the audio data can be retrieved from the Web Worker, and the audio file is compressed by the amrnb.js library, compressed into a specified format such as amr, and then uploaded to the server, the server stores Under the presentation (represented by the presentation ID) for subsequent loading.

Step 104, setting a speech focus action on the presentation element to gather according to the speech The focus action focuses on the presentation.

In the embodiment of the present application, for a presentation element that may be emphasized, a speech focus action may be configured thereon, so that when the presentation document is played, a focusing operation may be performed, so that the attention of the viewed user can be concentrated on the presentation. Document element.

In an embodiment of the present application, step 104 may include the following sub-steps:

Sub-step S31, determining a presentation element to be focused;

Sub-step S32, adding a focus element to the speech document element to be focused;

Sub-step S33, recording the focused element and the corresponding time point to focus on the focus document element to be focused when the speech document is played to the time point.

In the process of recording audio data, the user can trigger the presentation element of the current web page by means of a mouse click or the like, and add a focus element to the presentation element.

In one case, it may be determined that the presentation element to be focused is in a first position of the web page, and the second location is calculated in the web page based on the first location, such as in the upper left corner and the upper right corner of the first location The position is a second position or the like, and a focus element is added at the second position.

For example, as shown in FIG. 6A and FIG. 6B, the text "still night thinking" is a presentation element to be focused, with the upper left corner of the first position as a second position, and an arrow-shaped focusing element is added at the second position, Point to the text "Quiet Nights" and set its time point to 4 seconds, that is, you can play the text "Quiet Nights" in 0.9 seconds, play the arrow-shaped focus elements in 4 seconds, and focus on the text "Quiet Nights".

The embodiment of the present application loads a web page generated for a presentation in a client, and configures a presentation element in the web page, and further adds audio data to the presentation element on the timeline, so that the presentation can be played according to the timeline The elements are synchronized to play audio data, the audio data is re-added in the selected target time interval on the time axis, the web page is used as a carrier to create a presentation, and the audio data is used to realize the synchronous playing of the presentation elements and audio data for the user.
