Introduction to the Duolingo app

Duolingo is a language learning app developed by Duolingo, Inc.; it uses scientifically designed short lessons, gamified exercises, and personalized learning paths to help users improve their listening, speaking, reading, and writing skills. The app offers courses in over 40 languages, and it provides more interactive oral and conversation practice for eligible mobile users through AI-powered question answering, role-playing scenarios, and video calls with tutors.

Main functions of the Duolingo app

• More than 40 language courses:Users can choose the target language from courses in English, Japanese, Korean, French, Spanish, German, Italian, and others; they can also access content in Cantonese as well as some less common languages.
• Gamified short-course learning:The course is divided into concise units that can be completed on a daily basis; users progress through their learning path by answering questions, completing challenges, and receiving immediate feedback, making it suitable for continuous practice in short periods of time.
• Comprehensive training in listening, speaking, reading, and writing:The exercises cover various language skills such as listening comprehension, speaking, reading, and writing, and they involve the repeated use of vocabulary, sentence patterns, and grammatical knowledge through different types of questions.
• Personalized learning path:The system adjusts the content and key points for review based on the learner’s progress and performance in exercises, providing training that is more suitable for learners at different levels.
• AI for answering questions:The AI feature of Duolingo Max provides additional explanations for the user’s answers, helping to understand why a response is correct or incorrect; its availability depends on the course, platform, and subscription status.
• AI role-playing:Users can engage in real-life conversations with Duolingo characters in places such as coffee shops or stores, thereby organizing their expressions and practicing their practical conversation skills through contextual interactions.
• Video call with the cool girl:Eligible Max users can engage in real-time video conversations with the AI character Drag Sister on mobile devices, thereby practicing spontaneous spoken expression; the scope of this functionality is determined by the actual courses and devices available.
• Oral pronunciation practice:The application encourages users to respond by repeating after audio samples and answering voice-based questions, thereby developing proficiency in pronunciation, intonation, and oral expression through repeated practice.
• Special listening exercises:Users can focus on training their ability to recognize speech and understand sentence meanings in the target language, and they can strengthen their listening skills through activities such as dictation and multiple-choice questions.
• Practice Area:The practice area allows users to select the types of training they need, such as speaking, listening, vocabulary, and review of mistakes, which makes it easier to reinforce the content learned recently as well as the areas in which skills are weak.
• Review of wrong questions:The system identifies the errors made in the practice exercises and provides an opportunity for further training, allowing users to revisit those vocabulary items, sentence patterns, or concepts where they tend to make mistakes in order to strengthen their skills.
• Continuous learning motivation:The number of consecutive days of learning, experience points, and stage goals transform daily learning into a trackable habit, encouraging users to complete an appropriate amount of lessons each day.
• Leaderboards and interactions with friends:Users can compete in rankings and keep an eye on their friends’ learning progress, with community feedback and friendly competition serving to boost their motivation to stay committed over the long term.
• Immediate feedback and progress tracking:Immediate feedback is provided after each practice session, and the learning path keeps track of the progress made in the course, helping users to understand what has been completed and to move on to the next stage.
