In a small house with a wall painted pure green, as a "teacher" is lecturing in front of a green screen, the monitor displays not only real-time teaching videos, but also a series of pulsating data. This is the "AI Teacher Monitoring System" independently developed by TAL Education Group's Xueersi Online School, demonstrating the improvement in teaching quality brought by artificial intelligence. According to the introduction, the "AI Teacher Monitoring System" deeply integrates two major technologies: voice recognition and facial expression recognition, making real-time data structured and visualized in online classrooms. Teachers can adjust teaching content and methods based on real-time scoring to ensure a high-quality and fully interactive online classroom experience.

Recently, the 6th World Internet Conference was held in Wuzhen. At this conference, the online school's newly developed "AI Teacher" series products, including the "AI Teacher Monitoring System," "AI Teacher Word Memorization," "AI Teacher Language Learning System," and "VR Immersive Classroom," made their debut.

It is introduced that the "AI Teacher Monitoring System" has "two treasures" to help teachers improve teaching quality. One is voice recognition technology, which can recognize the teacher's teaching content in real time and analyze dimensions such as speech speed, volume, and pauses to depict clarity, fluency, and teaching focus, allowing the teacher to speak more clearly. The other is facial expression recognition technology, which can detect and analyze the teacher's facial expressions in real time during teaching, serving as an analysis of the classroom's affinity data. By recognizing and analyzing teaching gestures, the system evaluates the classroom's interactivity, making teacher-student interactions more effective.

At the same time, the "AI Teacher Language Learning System" made its second appearance at this conference. Through the iteration and optimization of original speech recognition and speech assessment technologies with a large amount of real data, as well as adaptive learning, the system is more adapted to the pronunciation characteristics of local students. The accuracy of oral assessment has been further improved, and the system has upgraded to include multiple languages, displaying common Chinese vocabulary in a "picture + bilingual pronunciation" mode. It is reported that this mode has been applied in Mandarin classrooms for about 80,000 Yi children in Zhaojue County, deep in the Daliang Mountains, enabling efficient learning of Mandarin through bilingual mode.

For the problem of many children struggling with learning English and memorizing vocabulary, "AI Teacher Word Memorization" deeply integrates five artificial intelligence technologies: voice recognition, speech assessment, speech synthesis, OCR text recognition, and screen handwriting recognition. With just a mobile phone, users can enter the text to be dictated by taking a photo. The "AI Teacher" can then correct it with one click, and can also generate a personalized word list based on the user's recitation records, helping with vocabulary learning practice and consolidation.

Currently, VR and AR technologies are accelerating their introduction into teaching scenarios, giving knowledge learning greater imagination. "An old friend bid farewell to the Yellow Crane Tower, in March the flowers are in full bloom in Yangzhou." With VR glasses, viewers can "enter" the tower, enjoying the structure and decoration of the building while listening to explanations of the Yellow Crane Tower's poetry. It is understood that Xueersi Online School is using VR technology to create new learning scenarios, allowing children to immerse themselves not only in the study of ancient poetry, but also in expanding the breadth and depth of classroom knowledge.
