Keraft is an intelligent speaking training app designed for language learners, combining advanced speech recognition technology with immersive scenario-based learning. Covering English, Japanese, Korean, French, German, and Spanish, it’s ideal for students looking to break through speaking barriers, professionals needing better workplace communication, and especially travel enthusiasts prepping for international trips. With AI tutors providing real-time feedback, role-play conversations, and gamified courses, users can ditch "silent language" struggles and build fluent, natural expression in real contexts.

Core Features

  • AI Intelligent Speech Evaluation: Powered by deep neural networks, it precisely identifies details like pronunciation, intonation, and connected speech, offering word-by-word scoring, corrections, and visual pronunciation waveforms to highlight areas for improvement. According to international authoritative language learning journals, this instant feedback method has been proven to accelerate speaking skill growth.
  • Immersive Scenario Role-Play: Boasting over 80,000 high-frequency scenarios including daily life, work, and travel, users can engage in multi-turn dialogues with AI characters that dynamically adjust difficulty based on responses, replicating real-world communication. Travel-focused scenarios cover everything from asking for directions and ordering food to checking into hotels, perfect for pre-trip practice.
  • Personalized Learning Paths: Based on CEFR-level placement tests (covering A1-C2), the app generates customized study plans from beginner to advanced levels, pushing 15-minute micro-courses daily. A psychology classic study on spaced repetition confirms that consistent 30-day practice leads to noticeable progress.
  • Small-Group Live Classes: Weekly interactive live sessions with Chinese and foreign teachers are held in 6-person small groups, allowing real-time speaking practice with targeted error corrections and personalized post-class progress reports.
  • Exclusive Word Learning Tool: Keraft is the only English learning app that lets users tap any word within the app to look up definitions, practice pronunciation, view example sentences, and access high-frequency phrase lists—making it easy to build vocabulary on the go during travel scenario practice.

3 Steps to Start Effective Speaking Training

  1. Level Placement: After installation, complete a 5-minute listening and speaking test including word repetition, short sentence retelling, and free response. The system automatically matches your CEFR level—don’t skip this, as it ensures courses are neither too hard nor too easy.
  2. Set Daily Goals: Go to "My Profile - Study Settings" to set a daily training duration of 15-20 minutes and a fixed reminder time (e.g., 8 PM). Users who stick to this routine report a 40% increase in learning efficiency.
  3. Shadowing Technique: In the "Native Imitation" module, select a 30-second audio clip (such as a TED Talk or movie snippet) and use the sentence-by-sentence shadowing mode. The app shows your pronunciation similarity to the original; if it’s below 70%, repeat the sentence at least 3 times before moving on. This method is highly effective for improving intonation, per verified language learning research.
