Problems solved by technology

[0003] Teachers usually choose ppt courseware, and ppt screenings are made in the order of production, but teachers do not teach in the order of ppt screenings in class. If teachers intersperse teaching content with lectures, it is difficult to find the corresponding ppt content, and they often browse ppt Waste time or don't read the ppt directly, which will easily affect the quality of teaching

Embodiment 1

[0044] Such as figure 1 As shown, the present embodiment provides a kind of intelligent teaching method based on voice analysis, including:

[0045] S101: Record the voice data of the user into the system, and save the voice data of the user as the first voice data;

[0046] S102: The user sends the courseware data to the system in advance, and the system saves the received courseware data;

[0047] S103: The user sets keywords in the courseware data, the system acquires the keywords and marks the keywords in the saved courseware data, and finally overwrites the original courseware data with the modified courseware data for save;

[0048] S104: Obtain all voice data and store the voice data as second voice data;

[0049] S105: Compare the second voice data with the first voice data, and determine whether there is voice data consistent with the voiceprint of the first voice data in the second voice data;

[0050] S106: If yes, extract the voice data with the same voiceprint...

Embodiment 2

[0066] Such as figure 2 As shown, extracting the courseware data including the keywords and performing data output include:

[0067] If a plurality of courseware data all include the keyword, count the number of occurrences of the keyword in the plurality of courseware data, and preferentially extract the courseware data with the largest number of occurrences of the keyword.

[0068] Specifically, the user divides the teaching materials into several courseware data, and the courseware data are all provided with independent keywords, and different courseware data may include the same keyword. In order to improve the accuracy of extraction in the present invention, the processing module in Before the courseware data is output, the courseware data needs to be screened, and the processing module extracts all the courseware data, and the judgment module judges whether the keyword is included in the courseware data one by one. After the judgment is completed, the processing module ...

Embodiment 3

[0070] Such as image 3 As shown, extracting the courseware data including the keywords and performing data output include:

[0071] If there is more than one keyword, the courseware data including all keywords are preferentially extracted;

[0072] If there is no courseware data including all keywords, extract the courseware data including the most keywords.

[0073] Specifically, there may be multiple keywords set by the user. Correspondingly, the third voice data may include several different keywords. The combination of this embodiment and the technical features of Embodiment 2 can further improve the efficiency of extracting courseware data. Accuracy, when the third voice data includes several different keywords, the processing module extracts all courseware data, and the judging module judges whether the courseware data includes the keywords one by one, if so, The processing module judges whether the courseware data includes all the keywords, if so, the processing modu...

Abstract

The invention discloses an intelligent teaching method based on speech analysis, which includes inputting the user's speech data into the system and saving the user's speech data as the first speech data; the user sends the courseware data to the system in advance, and the system will receive the Save the courseware data; the user sets the keywords in the voice data, the system obtains the keywords and marks the keywords in the saved courseware data, and finally saves the modified courseware data over the original courseware data; All the voice data and save the voice data as the second voice data; compare the second voice data with the first voice data, and judge whether there is voice data consistent with the voiceprint of the first voice data in the second voice data; Extracting voice data with consistent voiceprints as third voice data; judging whether keywords exist in the third voice data; extracting courseware data including keywords and performing data output.

Description

technical field [0001] The invention relates to the field of intelligent teaching, in particular to an intelligent teaching method and system based on speech analysis. Background technique [0002] Electronic courseware is gradually used in modern teaching to replace traditional paper courseware. Electronic courseware is very different from traditional paper-based courseware. The main difference is that this courseware is not only for teachers to read in class, but also for projecting the content on the screen for students to see. This electronic courseware includes all blackboard writing, blackboard drawing and some dynamic scenes that are difficult to express in language. Classes with electronic courseware do not need a blackboard. Classes with electronic courseware can increase the classroom capacity, allow students to learn knowledge in a wonderful sound, light, and electricity environment, and enhance the learning effect. [0003] Teachers usually choose ppt coursewa...
