AI application platform in English review

PolyPi AI applies artificial intelligence technology to mark and correct pronunciation and writing errors, allowing users to choose teachers to practice speaking English.

Through the direct connection platform, students can choose teachers for support and 1-1 review. PolyPi AI will provide information about each teacher's qualifications, years of experience and tuition fees, helping learners take the initiative in participating in the right class.

The unit representative shared that the platform uses 100% artificial intelligence during the training process. Students are given detailed instructions in online classes with teachers of their choice and actively practice at home.

As a result, PolyPi AI provides scoring and correction of speaking skills. For example, in the accent section, AI technology uses natural language processing algorithms to analyze and identify pitch in each word, sentence, and the entire speech of the student.

At the same time, the system uses a machine learning model to compare the student's pronunciation with the standard intonation in the IELTS exam through sound characteristics and voice frequency. From there, the system can evaluate pronunciation and give advice.

PolyPi AI also analyzes the student's speaking speed by determining the number of words or syllables uttered in a given period of time. Then, based on the speaking speed requirements in the IELTS exam, the system provides feedback and suggests corrections.

Finally, from the above indicators and the IELTS speaking scoring algorithm, the platform will automatically score and give a quick score, along with suggestions for improving the speaking.

In addition, PolyPi AI has developed many features to help students practice writing skills. PolyPi's AI technology applies standard language and grammar models to analyze writing, thereby identifying grammatical errors in sentence structure, subjects, verbs, etc., including rare errors. In addition, the application developer has trained on a big data model of the English language to be able to identify and suggest corrections.

This section also has a scoring feature. The system uses the IELTS scoring criteria including: idea organization, grammar, vocabulary and language usage, and from there, gives an accurate score.

With support for reading and listening skills, PolyPi AI allows students to automatically look up words, including specialized words. The application can provide definitions, examples, and related word information to help students understand the meaning and usage.

"The AI system applies natural language processing models to analyze passages and summarize the main meaning. This helps students understand the content easily and grasp the main idea of the reading," the unit representative affirmed.

In addition, PolyPi AI also has a paragraph summary feature by identifying main ideas, relationships between sentences and important information to create a concise and logical version.
