[0039] Among them, the microphone 111 can be used to collect classroom audio, the speaker 112 can be used to play pre-class speech, and the recorder 113 can be used to execute the steps of the auxiliary teaching method based on the recording and broadcasting device of this application.

[0040] See also Figure 2 The auxiliary teaching method based on recording and broadcasting equipment provided in this application specifically includes the following steps:

[0041] S110: Acquire teaching information; wherein the teaching information includes the course start time;

[0042] The teaching information may be information directly input by the teacher through an input device connected to the recorder, the input device includes but is not limited to a keyboard, a mouse and other devices, or the teaching information may be information input by the teacher through a teacher terminal connected to the recorder. The hardware pointed to by the teacher terminal essentially refers to computer equipment, specifically, it may be a smart phone, a smart interactive tablet and a personal computer and other types of equipment, and the teacher terminal may access the Internet through a known network access method to achieve communication connection with the recorder.

[0043] The course start time is used to determine the time when the teacher starts teaching. Before the course start time, the teacher has not started teaching. When the course start time is reached, it means that the teacher starts teaching at this time.

[0044] S120: Before the course starts, control the speaker to play the pre-class speech;

[0045] The pre-class voice may be an audio pre-set by the user for playing before class. Specifically, the pre-class voice may be a prompt audio for reminding students to prepare for class. After hearing the pre-class voice, students may make corresponding preparations for class to avoid missing class time.

[0046] Alternatively, in another embodiment, the pre-class voice may include explanatory audio for the class theme, summary, background, review of key points of the previous class, etc. The explanatory audio can be input into the recorder in advance by the teacher, or the recorder obtains the classroom audio or classroom audio clips of the previous class stored in the database. Students can review the content of the previous class through the pre-class voice, deepen their understanding of the content of the previous class, and improve the quality of teaching.

[0047] S130: After the course starts, controlling the microphone to collect classroom audio;

[0048] Classroom audio can be used to extract and record the key knowledge points involved in the teacher's teaching process, making it convenient for students to review after class and for teachers to review after class, thereby improving the quality of teaching.

[0049] S140: Perform voice analysis on the classroom audio, obtain key knowledge points in the classroom audio and store them in a database;

[0050] When analyzing classroom audio, specifically, the classroom audio can be first converted into text, and then the key knowledge points can be obtained by analyzing the text.

[0051] like Figure 3 As shown, in one embodiment, the step of obtaining the key knowledge point information in the classroom audio specifically includes:

[0052] S141: Performing speech recognition on the classroom audio to obtain a classroom text corresponding to the classroom audio;

[0053] S142: Perform text analysis on the classroom text to obtain key knowledge points of the classroom text.

[0054] When obtaining the classroom text corresponding to the classroom audio, the voice recognition program pre-installed in the recorder can be used to obtain it, or the recorder can also call the existing voice recognition interface through the network to obtain the classroom text.

[0055] When obtaining key knowledge point information, specifically, the position information of the knowledge point in the classroom text can be obtained by first analyzing the knowledge points in the classroom text, and then the relevance of the contextual content near the location of the knowledge point and the knowledge point can be analyzed to determine the target position information of the location of the key knowledge point, thereby obtaining the key knowledge point information based on the target position information.

[0056] When performing knowledge point analysis on classroom text, the knowledge point analysis model pre-trained by the user may be used to obtain location information of the locations of the knowledge points in the classroom text.

[0057] S150: After the course ends, in response to the question information sent by the student terminal, keyword information in the question information is extracted, and target knowledge key point information corresponding to the keyword information is obtained from the database and returned to the student terminal.

[0058] The question information may be text information or voice information. When the question information is voice information, after receiving the question information, the recorder performs voice recognition on the question information to obtain text information corresponding to the question information.

[0059] When extracting keyword information, a keyword extraction model pre-trained by a user may be used to obtain the keyword information.

[0060] When obtaining the target knowledge key points information, the keyword information can be specifically matched with the knowledge key points information stored in the database, and the matched knowledge key points information can be used as the target knowledge key points information corresponding to the question information and returned to the student end, so that the student end can get the corresponding answer according to the target knowledge key points information, which is more convenient for students to understand and consolidate the knowledge points in class.

[0061] In one embodiment, the teaching information may include the course end time, and the course is determined to be over when the current time reaches the course end time; or, in another embodiment, whether the course is over can be determined based on the classroom audio signal collected by the microphone. For example, if it is determined based on the classroom audio that the course time has exceeded the target course time, and the volume of the classroom audio is less than the volume threshold, the course is determined to be over; or, if the classroom audio contains a get out of class end signal, the course is determined to be over; wherein the get out of class end signal can be the teacher's voice signal of "get out of class end".

[0062] In an embodiment of the present application, a recorder is used to control a speaker to play a pre-class speech before the course starts. After the course starts, the microphone is controlled to collect classroom audio, and key knowledge points are obtained by voice analysis of the classroom audio and stored in a database. After the course ends, the recorder can respond to question information sent by the student end, obtain corresponding key knowledge points from the database and return it to the student end, thereby utilizing the idle computing resources of the recorder to assist teachers in teaching, reduce teachers' burden, and improve teaching quality.

[0063] See also Figure 4 , which is a schematic diagram of an application scenario of another embodiment; Figure 4 As shown, the application scenario includes a display screen 130, and the display screen 130 can be used to display the teacher's courseware, key points of knowledge and other contents.

[0064] like Figure 5 As shown, in one embodiment, the auxiliary teaching method based on the recording and broadcasting device further includes the following steps:

[0065] S210: receiving the courseware input by the teacher;

[0066] S220: After the course starts, controlling the display screen to display the courseware.

[0067] The courseware may be input by the teacher before or after the course starts. The courseware may include the theme, summary, background knowledge or key points of the lesson, and may be set according to the teacher's class needs.

[0068] When the teacher starts teaching, the display screen 130 is controlled to display the courseware to help students understand the course content and improve the teacher's teaching quality.

[0069] In step 140, the key knowledge point information may be obtained from the courseware of the teacher's class in addition to being extracted from the classroom audio of the teacher's class. In one embodiment, the following steps are also included:

[0070] Extract key knowledge points from the courseware and store the key knowledge points in a database.

[0071] The courseware may include the theme, summary, background knowledge or key points of the lesson. Therefore, this application avoids missing key points by extracting key points from classroom audio and courseware, thereby ensuring the comprehensiveness of the key points stored in the database.

[0072] In another embodiment, the display screen 130 may also be used to display key knowledge point information, specifically, the following steps are also included:

[0073] In response to a display instruction, display the key knowledge point information on the display screen according to the display instruction;

[0074] The display instructions may be control instructions input by the teacher through an input device such as a mouse, laser pen, keyboard, etc. connected to the recorder.

[0075] Alternatively, in another embodiment, after voice analysis is performed on the classroom audio, if the classroom audio includes a display voice instruction, the key knowledge point information is displayed on the display screen according to the display voice instruction.

[0076] The display voice command is a command input by the teacher through voice to display the key points of knowledge on the display screen. The display voice command can be a pre-set voice command. When it is detected that the classroom audio contains the display voice command, the key points of knowledge are displayed on the display screen, so as to facilitate students to record and understand the key points of knowledge in this class.

[0077] like Figure 6 As shown, in one embodiment, after performing voice analysis on the classroom audio, the following steps are also included:

[0078] S310: If the classroom audio includes a voice control instruction, obtain the knowledge point audio corresponding to the knowledge point information;

[0079] S320: Control the speaker to play the audio of the key points of knowledge according to the voice control instruction.

[0080] The audio of key points of knowledge can be the audio of the class theme, summary, background knowledge or key content. The audio of key points of knowledge can be the audio pre-recorded by the teacher and input into the recorder.

[0081] The voice control instruction is an instruction input by the teacher through voice to control the loudspeaker to play the audio of the key knowledge points corresponding to the key knowledge points.

[0082] Among them, the voice control instruction can be a pre-set voice instruction. When it is detected that the classroom audio contains the voice control instruction, the speaker is controlled to play the audio of the key points of knowledge. Therefore, when the teacher is taking a break or it is inconvenient to speak, the audio of the key points of knowledge can be played through the speaker to assist teaching and improve the teaching quality.

[0083] In step S150, the student can input question information through the student terminal and obtain answers to the questions by receiving the key knowledge point information returned by the recorder, wherein the input question information and key knowledge point information can be displayed on the display screen in the form of text.

[0084] Specifically, the method further comprises the following steps:

[0085] After the course is over, the display screen is controlled to display a first interactive question-and-answer interface; wherein the first interactive question-and-answer interface is used to display the question information and the target knowledge key points information.

[0086] Or, if Figure 7 As shown, in another embodiment, the question information and the key knowledge point information can be displayed in the form of text on the display interface of the student terminal. Specifically, the method further includes the following steps:

[0087] S410: After the course ends, controlling the display screen to display a code scanning interface; wherein the code scanning interface includes a scan code;

[0088] The scan code may be a common scan barcode such as a QR code or a barcode.

[0089] S420: In response to the scanning operation of the scanning code by the student terminal, the interactive question-and-answer interface data is sent to the student terminal, so that the student terminal displays a second interactive question-and-answer interface according to the interactive question-and-answer interface data; wherein the second interactive question-and-answer interface is used to display the question information and the target knowledge key point information.

[0090] After the course is over, the student terminal can enter the second interactive question-and-answer interface by scanning. The second interactive question-and-answer interface may include a question information input box. Students can enter question information through the question information input box and send it to the recorder through the student terminal. The input question information and the target knowledge point information returned by the recorder can be displayed in the second interactive question-and-answer interface.

[0091] In other embodiments, the student terminal may also include a label module, and the student terminal establishes a communication connection with the recorder by bringing the label module into close contact with the recorder, so that the student terminal obtains interactive question-and-answer interface data from the recorder, and displays a second interactive question-and-answer interface based on the interactive question-and-answer interface data, wherein the label module may include tags such as NFC.

[0092] Alternatively, in another embodiment, the student end includes a speech synthesis module and a playback module. After receiving the target knowledge key point information, the student end can use the speech synthesis module to generate the target knowledge key point audio corresponding to the target knowledge key point information, and play the target knowledge key point audio through the playback module; wherein the playback module can be a speaker, audio or other module.

[0093] In the embodiment of the present application, after the class is over, the student can enter the interactive question-and-answer interface by scanning a code or making NFC contact, thereby simulating interaction with the teacher in the interactive question-and-answer interface to ask questions and obtain answers, thereby deepening the student's understanding of the key points of knowledge and improving the interest and teaching quality of after-school teaching.
