S101, writing a current explanation script for the current slide to be explained in advance, wherein the current explanation script includes: the current text to be read aloud and the current command to be executed;

In the embodiment of the present invention, an explanation script is written in advance based on experience or specific conditions, wherein the current explanation script includes the current text to be read and the current command to be executed, wherein the text to be read is a description of the current to be explained The explanation of the knowledge in the slide, the current execution command is the operation instruction executed during the explanation, for example, appropriate pause, show animation in the slide, or open other documents or applications, etc., wherein the current explanation text The existence form can be a file that is independent from the current slide to be explained, and the file can be associated with the corresponding slide through the identifier, or it can be associated with the remarks page of the slide to be explained. In the embodiment of the present invention, the specific association is Form restrictions.

Further, the current slide to be explained is at least one, and the slides are arranged in sequence according to the explanation order.

S102, in the case of receiving an automatic explanation request for the current slide to be explained, obtain the current explanation script;

In this embodiment of the present invention, when an automatic explanation instruction is received, the current slide show to be explained is determined based on a pre-established association relationship, wherein the pre-established association relationship may be constructed based on an identification and a remarks page or in other ways. The current explanation script of the film, wherein the automatic explanation instruction may be implemented by the user by clicking a button or a related play key, etc., which is not specifically limited in this embodiment of the present invention.

S103, identifying the current explanation script, and determining the current text to be read and the current command to be executed in the current explanation script;

In this embodiment of the present invention, the current explanation script is traversed, and the content contained in the current explanation script is identified in sequence. Preferably, because the current explanation script only includes the current text to be read and the current command to be executed, and , the current text to be read aloud is at least one, each current text to be read can be the same or different, the current command to be executed is at least one, and each current command to be executed can be the same or different. In the explanation script, for each current command to be executed in the current explanation script, a start mark and an end mark are allocated, starting with the start mark, and ending with the end mark, which will be included in the start mark. The part between the end mark and the end mark is used as the current command to be executed, and the part between the execution commands is the current text to be read, wherein, in this embodiment of the present invention, the start mark and the The specific existence form of the end identifier is not limited.

For example, taking the current explanation script as an example, assuming that the start identifier is [, the end identifier is], then the current explanation script is: A, [command 1] [command 2] BC [command 3] , in the above current explanation script, ABC is the text to be read aloud, and command 1, command 2 and command are the current commands to be executed

S104: Read the currently to-be-read text and execute the currently-to-be-executed command in sequence.

In the embodiment of the present invention, after the current text to be read aloud and the command to be executed currently are determined, for the voice explanation part, the voice reading engine in the text-to-speech conversion technology TTS (TextToSpeech) recognizes the current text to be read aloud and generates The specific conversion principle is as follows:

Text Analysis - Linguistic analysis of the current text to be read, sentence-by-sentence lexical, grammatical and semantic analysis, to determine the low-level structure of the sentence and the composition of the phonemes of each character, including text segmentation, words Segmentation, processing of polyphonic words, processing of numbers, processing of abbreviations, etc.

Speech synthesis - Extract the words or phrases corresponding to the processed text to be read aloud from the speech synthesis library, and convert the linguistic description into speech waveforms.

Prosody processing-synthetic quality (Quality of Synthetic Speech) refers to the quality of the speech output by the speech synthesis system, which is generally evaluated subjectively in terms of clarity (or intelligibility), naturalness and coherence. Clarity is the percentage of correct hearing and recognition of meaningful words; naturalness is used to evaluate whether the sound quality of the synthesized speech is close to the voice of a human being, and whether the intonation of the synthesized words is natural; coherence is used to evaluate whether the synthesized sentences are fluent.

Since com.cloudgarden.jsapi is used to access the TTS function of Windows, the implementation of the TTS manager is relatively simple. TTSMan provides two basic functions: speak, read the given text aloud; setSpeed, set the reading speed.

For the part of the command to be executed currently, in this embodiment of the present invention, if the current command to be executed in the current explanation script is parsed, a preset command set is traversed, a method corresponding to the command to be executed currently is searched, and a method corresponding to the command to be executed is executed. Operation instructions corresponding to the above methods. If the current command to be executed is a command supported by openoffice, call the API of openoffice to realize the corresponding function; if the command is java, use java to realize the corresponding function. The startup of the automatic explanation software is handed over to the BeanShell script to complete. The content of the script is as follows:

In the embodiment of the present invention, the current command to be executed is a beanshell script, and the execution command to start a slide show is taken as an example:

In fact, the command manager is called to obtain the PPT Proxy object, and then the startPresenting (target) method of the object is called to start the show. The preset command set is given below. These commands can be invoked on demand in the current tutorial script. The preset command set includes: CANCEL(), DL(long), DL1(), DL2(), DL3(), EXITFUYIN(), GOTO(int), NE(), NOOP(), NS( ), PAUSE(), PAUSEs(String), PE(), PLAY(), PS(), q_jsapiSpeak(String), q_parseNote(String), q_speakAllSlides(), q_speakCurrentSlide(), q_speakFollowSlides(), RANDi(int), RANDi2(int,int), RANDs(String), RESUME(), SPEAK(String), SPEAKs(String,String), SPEED(int), SRTALIGN(int), SRTBOUND(int,int,int,int), SRTCOLOR (int,int,int,int), SRTFONT(String,int,int), SRTOPACITY(float), SUBTITLE(String) and SWITCHSRT() For example, the current command to be executed is "[SPEED(160);]Hello World [] How are you" which calls the SPEED command to set the reading speed to 160 words per minute. Note that "[]" is the command, please use English half-width symbols for parameter brackets and statement semicolons in these commands.

The invention discloses an automatic explanation method for slides, which includes: pre-writing a current explanation script for the current slide to be explained, wherein the current explanation script includes: the current text to be read and the current command to be executed, In the case of the automatic explanation request of the slides to be explained at present, obtain the current explanation script; identify the current explanation script, and determine the current text to be read and the current command to be executed in the current explanation script ; Read the text to be read aloud and execute the command to be executed in sequence. In the above process, the current explanation script is written for the current slide to be explained in advance, the reading of the text to be read in the explanation script and the execution of the operation instruction corresponding to the to-be-executed command in the explanation script are completed, and the corresponding function is realized based on the operation instruction. In order to deal with the automatic explanation of the slideshow, complete the learning of the relevant knowledge in the slideshow.

In the embodiment of the present invention, the method further includes: adding a control interface, and controlling and displaying any slide to be explained based on the control interface, wherein the control interface (ControlFrame) is a simple window, which contains various Buttons to control functions. After clicking these buttons, the corresponding operations are completed by sending corresponding commands to the command manager. The control interface manager controls the generation and display of the ControlFrame. Wherein, the control interface can complete the functions of Current, Following, ALL, Cancel, Resume and subtitle.

Further, acquiring the current text to be read aloud; while reading the text to be read aloud, the current text to be read aloud is synchronously displayed at a preset position in the current slideshow to be explained, so as to realize a subtitle function, The subtitle function is to construct a JFrame without a title bar to display the subtitle text in a given format, and the preset position for displaying letters is not limited in the embodiment of the present invention.

Further, in this embodiment of the present invention, JNA is used to monitor mouse and keyboard events within the system. The JNA class library uses a small native class library sub to dynamically call native code. The programmer only needs to use a specific java interface to describe the structure and some basic properties of the method to be called by the native code. This saves a lot of configuration and compilation code for adapting to multiple platforms. Because the calls are all the interfaces in the public jar package provided by JNA.

Based on the interception of mouse and keyboard events by JNA, a set of Event and EventListener mechanisms are simply defined to support users to flexibly register event response codes. Based on this, support for the following shortcut keys and commands is implemented:

Start the slide show (Alt+G, ASCII code 71), execute the command: PLAY();

Read all pages (Alt+A, ASCII code 65), execute the command: q_speakAllSlides();

Read the following page (Alt+F, ASCII code 70), execute the command: q_speakFollowSlides();

Read the current page (Alt+C, ASCII code 67), execute the command: q_speakCurrentSlide();

Pause the explanation (Alt+K, ASCII code 75), execute the command: PAUSE();

Continue to explain (Alt+R, ASCII code 82), execute the command: RESUME();

Cancel all explanation content (Alt+X, ASCII code 88), execute the command: CANCEL();

Display/hide subtitles (Alt+S, ASCII code 83), execute command: SWITCHSRT();

In the embodiment of the present invention, based on the above method, an automatic explanation software for flipped classroom is designed, which runs in OpenOffice (compatible with LibreOffice, the same below) and exists in the form of a plug-in of OpenOffice. OpenOffice (LibreOffice) is the latest version available after December 2016. The automatic explanation software for flipped classroom is developed in Java language, so it is required to correctly configure the JDK used by OpenOffice (version JDK1.6 or above, 32-bit x86).

The development environment is as follows:

Integrated development environment: Eclipse Mars and above;

Source code repository: git;

Maven repository: Nexus.

In the embodiment of the present invention, the automatic explanation software mainly includes 7 categories: the IPPTProxy interface is used to abstract the slideshow software, so that the system can support more slideshow software in the future. BshOpenOfficeProxy is an implementation of IPPTProxy for OpenOffice. It obtains some necessary information through the BeanShell script supported by OpenOffice, so as to implement the functions defined in IPPTProxy for use by other modules.

CommandMan, the command manager, is used to manage and execute individual commands. By expressing instructions in the form of beanshell scripts, users are allowed to execute and extend various types of commands. CommandMan also holds the implementation object of IPPTProxy, so that other modules can access the functions of the PPT player through it.

MouseKeyboardMan, a mouse and keyboard manager, is used to manage system-wide mouse and keyboard operations. It encapsulates these operations as events by monitoring mouse and keyboard operations, and supports event listeners. Thereby, the user's registration of the hot key is finally realized and the corresponding instruction is executed. Note: Ordinary Java code can only monitor keyboard and mouse events within the scope of the interface control (such as a form) where it is located. Once the control loses focus, it cannot continue to monitor. MouseKeyboardMan is used to listen for system-wide mouse and keyboard events, regardless of which interface the focus is on.

SRTMan, subtitle manager, is used to control the form that displays subtitles, GUIController, control interface manager, controls the main interface (ControlFrame) form.

TTSMan, TTS manager, is used to manage the speech reading engine. It uses the com.cloudgarden.jsapi package to directly call various speech libraries installed in the Windows system, and supports SAPI5.

Among them, the PPT control interface (IPPPTProxy) defines the following functions:

startPresentin, start the slideshow.

isPresenting, to determine whether it is showing.

getSlideCount, get the number of slides in the file.

getCurrentShowSlideIndex, get the current slide index value.

gatherNoteOfShowSlides, get the note text of the slides in the specified range in the presentation, calling this method will cause the show to start.

getNoteOfShowSlide, get the note text of the specified index slide in the presentation, calling this method will cause the show to start.

gatherNoteOfSlides, get the note text of the slides in the specified range, calling this method will not start the slide show.

getNoteOfSlide, get the note text of the specified index slide, calling this method will not start the slide show.

nextEffect, Show next effect of this slide in presentation.

nextSlide, Show next slide in presentation.

previousEffect, Show previous effect of this slide in presentation.

previousSlide, Show previous slide in presentation.

gotoSlide, goto given slide in presentation.

onExiting, the system is ready to exit and recycle used resources.

Once the above functions are provided for a PPT player, the automatic explanation software for flipped classroom can complete the control of the acquisition and explanation of notes.

BshOpenOfficeProxy is supported by OpenOffice's BeanShell script. By obtaining the three main objects: XScriptInvocationContext, XModel and XDesktop, you can use OpenOffice's UNO interface to access related objects: XPresentationSupplier, XPresentation, XPresentation2, XDrawPagesSupplier, thus realizing IPPTProxy defined function. These classes and their functions are defined in UNO and OpenOffice.

The command manager (CommandMan) has a command queue (CommandQueue: mainQueue) inside, and the command queue may include command items (ICommandQueueItem). ICommandQueueItem has two subclasses: CommandQueueItem and CommandQueue. The former is used to encapsulate a specific command, and the latter means that the queues can be nested to form a nested queue. Nested queues could in the future allow users to revoke command sequences within a specified range, thereby enhancing control.

After the command manager starts, a command execution thread is started. The command execution thread continuously gets the command item from the mainQueue (calling the advanceCommand method), and then executes it. The command in each command item is a beanshell script. CommandMan internally creates a BeanShell interpreter (and executes the command script described later), and then submits the command to the interpreter for execution.

In the embodiment of the present invention, in order to further enhance the functions, a static web page server and a WebSocket message forwarding server are provided, so that devices such as mobile phones and head-mounted VR/AR glasses can be supported. The static web page server supports access to the static web page by monitoring the specified port, responding to the HTTP GET request of the port, and returning the requested static web page file data. This extension provides three access interfaces: void setRootPath(String path), which sets the root directory of the web page; boolean start(String path, int port), which starts the HTTP web server with the parameters of the web page root directory and listening port number; void stop() , to stop the HTTP web server. Among them, the WebSocket message forwarding server is based on WebSocket, and supports different clients to broadcast messages through web pages. This module will listen on the specified ports of all available network cards on the host, receive incoming text messages, and broadcast them to all connected clients. List<String>getHostIps(), get the IP addresses of all network cards bound to the WebSocket message forwarding server; List<String>start(intport), start the WebSocket message forwarding server on the specified port, and return the IP addresses of all bound network cards ;voidstop(), stop the WebSocket message forwarding server. void bcastMessage(String msg), broadcasts a text message. Messages starting with ":bsh:" will be sent to the command manager and interpreted (not sent to individual clients).

Based on the static web server and WebSocket message forwarding server, it can support mobile phones, VR/AR glasses and other devices to receive information such as voice in PPT, and can transmit control commands at the same time. For example, in the following web page, buttons such as "Show" can send commands such as ":bsh:PLAY();". When the WebSocket message forwarding server receives it, it is forwarded to the command manager and interpreted and executed (show command).

Due to the use of WebSocket technology, the client can customize the interface according to the device and user preferences. For example, the interface of the AR device MadGaze is simplified as follows:

When using devices such as MadGaze, instant explanation content prompts can be realized, so that the speaker can walk away from the podium at will while wearing the glasses. The same effect can be achieved using mobile phones, etc.
