Embodiment 1

[0028]Embodiments of the present invention provide a method for assessing students' expressive ability, such as figure 1 shown, including:

[0029] Step S10: Obtain the audio data and video data of the target classroom. The audio data includes the audio of the target student speaking, and the video data includes the video image of the target student speaking. In a specific embodiment, audio and video are set in the classroom. Acquisition devices, such as cameras and microphones, the audio of students speaking can be collected through the microphone, and the video images can be collected through the camera.

[0030] Step S20: Obtain the audio characteristics of the target student according to the audio data. The audio characteristics include at least one audio index, and the audio index can include one or more of pronunciation index value, intonation index value, speech rate index value, and volume index value. Among them, the pronunciation index value is used to indicate whe...

Embodiment 2

[0085] An embodiment of the present invention provides a device for assessing students' expressive ability, such as Figure 7 shown, including:

[0086] The audio and video data acquisition module 10 is used to acquire the audio data and video data of the target classroom. For a detailed description, refer to the description of step S10 in the first embodiment above.

[0087] The audio indicator acquisition module 20 is configured to acquire the audio features of the target student according to the audio data. The audio features include at least one audio indicator. For a detailed description, see the description of step S20 in the first embodiment above.

[0088] The expression index acquisition module 30 is used to acquire the expression characteristics of the target student according to the video data. The expression characteristics include at least one expression index. For a detailed description, see the description of step S30 in the above-mentioned embodiment 1.

Abstract

The invention provides a student expression ability evaluation method and device, and the method comprises the steps: obtaining the audio data and video data of a target classroom; obtaining audio features of the target student according to the audio data, wherein the audio features at least comprise one audio index; obtaining expression features of the target student according to the video data,wherein the expression features at least comprise one expression index; respectively determining the comprehensive weight of each audio index and the comprehensive weight of each expression index; calculating an expression ability score of the target student in the target classroom according to the value of each audio index, the value of the expression index and the comprehensive weight of each audio index and the expression index; and calculating a comprehensive expression ability score of the target student in the preset period according to the expression ability scores of the target studentin different time periods in the preset period and the time weights of the target student in different time periods in the preset period. The comprehensive expression ability score of the target student, which is calculated by implementing the method, is more accurate.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for evaluating students' expressive ability. Background technique [0002] Expressive ability is the ability to express one's thoughts and emotions clearly and clearly with language, facial expressions, actions, etc. In traditional exam-oriented education, schools are usually "result-oriented" and pay more attention to the cultivation of students' written language and academic performance, while the cultivation of expressive ability has long been neglected. With the gradual transition of basic education to quality education in our country, oral expression has become one of the core abilities for students to cultivate. The current Putonghua test is a more authoritative way to evaluate students' expressive ability, but the Putonghua test focuses more on testing whether students' Putonghua is standard, and the standard of Putonghua is not the only criter...
