The Greelan language learning system software is based on TCP/IP communication protocol, with high-quality and delay-free speech coding and transmission technology. It integrates multimedia teaching, language laboratories, examination systems, multi-functional teaching and training centers, etc. into a professional interactive pure software language laboratory software that combines multiple rooms into one.

1. Diverse visual teaching platforms

"Video interactive teaching" is a very important function in language teaching activities, and it is also one of the unique features of the Greelan language learning system software. Greelan software ensures clear sound and smooth image quality through its own research and development technology and innovative breakthroughs, achieving authenticity in language teaching and learning.

In teaching activities, teachers and students can use system software functions combined with cameras (or other physical exhibition stands, electronic whiteboards, and other equipment) to allow both parties to see each other's video images during dialogue, live broadcast communication on-site, accurately learn and correct pronunciation and mouth shape; at the same time, they can invest in dialogue emotions, increase close attention to teacher-student interaction, and easily achieve the effect of improving classroom efficiency and creating a good atmosphere for language learning.

2. Oral Training Platform

The Greelan language learning system software combines classroom teaching with professional foreign language learning and practical vocational application needs, refining them into oral training functions. It designs professional oral training platforms such as role-playing, visual simultaneous interpretation, repetition practice, and oral training, transferring movie scenes, foreign trade business negotiations, international meetings, and other scenarios into classroom training. It breaks away from the tedious traditional oral training method of single listening and reading, innovates open-ended voice teaching, and gradually improves students' oral ability.

At the same time, other auxiliary functions such as full-time recording, screen recording courseware, video interaction, etc. can be combined to enrich the content of oral training, with smooth synchronization of picture and sound, ensuring high-quality listening and speaking teaching.

3. Personalized group teaching platform

The Greelan language learning system software provides personalized group teaching features. Teachers can arrange foreign language corners on different topics, with all participants engaging in thematic discussions. Alternatively, outstanding students can take on the role of group leaders and demonstrate teaching techniques. The system can utilize existing groupings, create temporary groupings, or randomly assign groupings. During group discussions, members can freely make video calls and transfer files without interfering with each other.

   According to the difficulty or classification of topics, targeted differentiated training can be arranged for students to alleviate the pressure of large differences in oral English. Excellent students can also be arranged to "lead a group", where students can learn from each other's strengths and narrow the gap in performance. Group teaching can break through the physical limitations of the classroom, stimulate students' interest and enthusiasm, and make it easy for students to speak foreign languages. At the same time, full-process recording can be arranged to record and store the discussion content of the group, which can be reviewed after class.

4. Professional Examination Platform

   As a professional foreign language laboratory software, the Greelan language learning system software has designed a comprehensive and detailed examination module that can meet the needs of various forms of standardized exams, listening exams, classroom quizzes, oral exams, and more.

   Oral examination controls details, applicable to professional foreign language oral examination; standardized examination supports independent proposition, diversified question types, listening examination, differentiated examination; classroom test and answer sheet test, teaching and testing at the same time, multi-directional test.

 5. Integrate teaching management and classroom management
