[0057] It also includes a first start-up module connected to the teacher's sound receiving sub-module signal and a second start-up module set at the target student's sound receiving sub-module and connected to the target student's sound receiving sub-module signal. The teacher triggers the start of the teacher's sound receiving sub-module by controlling the first start-up module, and the target student triggers the target student's sound receiving sub-module by controlling the second start-up module.

[0058] The execution module includes the following submodules:

[0059] The controller module completes various receiving, sending and processing tasks;

[0060] Noise reduction module, which performs noise reduction processing on the received voice;

[0061] The speech enhancement module performs voice enhancement on the speech after noise reduction processing;

[0062] The sound adjustment module is used to adjust the sound index data of the sound after the human voice enhancement processing according to the set voice adjustment model.

[0063] It also includes a scoring module, which teachers use to assign scores to the answers of target students after the question-and-answer session.

[0064] The controller module calculates the target student's class behavior score based on the statistics of the number of times the second startup module of the target student is triggered and the assignment of the scoring module within the statistical period Z, and obtains the target student's classroom interaction score HDF. The calculation formula is as follows:

[0065]

[0066] Among them, C K represents the number of times the target student triggers the second startup module in cycle Z, C 平均 represents the average number of times the second start-up module is triggered by all students in the class within period Z, n represents the total number of students in the class, A and B are both weighted coefficients and A+B=100%, Indicates the score assigned by the teacher to the target student's answer after a question and answer session within the cycle.

[0067] The HDK is divided into three levels according to the set values ​​Q and W, wherein Q>W, HDK>Q represents the superior level, Q>HDK>W represents the middle level, and W>HDK represents the inferior level.

[0068] By setting up a scoring module, teachers can complete the scoring work of student question-and-answer interactions and the teaching quality management work of each target student, which is convenient for teachers to understand the overall situation of the class. Accurate statistics and calculation results can be given for each independent target student, which is more conducive to teachers understanding the students' situation and further improving the teaching quality. The work of the scoring module in this embodiment is illustrated as follows:

[0069] The statistical period Z is set to one month, the number of students in the class is n is 50, and it is assumed that C K =10, C 平均 =8, A = 80%, B = 20%. The teacher's score for each of the target student's 10 questions and answers is as follows:

[0070] <![CDATA[FF 1 ]]> <![CDATA[FF 2 ]]> <![CDATA[FF 3 ]]> <![CDATA[FF 4 ]]> <![CDATA[FF 5 ]]> <![CDATA[FF 6 ]]> <![CDATA[FF 7 ]]> <![CDATA[FF 8 ]]> <![CDATA[FF 9 ]]> <![CDATA[FF 10 ]]> 6 6 7 7 10 6 9 5 12 8

[0071] The calculation is as follows

[0072]

[0073] Then the target student’s HDK in period Z is 2.52

[0074] Set Q = 3 and W = 2

[0075] Then Q>HDK=2.52>W, which means that the target student's question-answering level in period Z is medium;

[0076] In summary, the present invention can greatly improve the quality of communication between students and teachers during question-and-answer communication in English, thereby improving the quality of English phonetics teaching, making it more convenient for teachers to complete their teaching work, and helping teachers to effectively control the question-and-answer teaching situation in the class at both the macro level and the micro level of target students, thereby helping teachers to make targeted teaching adjustments and improve teaching quality.
