According to the EF EPI Global English Proficiency Report, speaking is the weakest skill for Chinese English learners, with over 60% of learners stuck in a cycle of hesitant speech, lack of language partners, and uncorrected pronunciation, often described as "mute English". As AI technology reshapes language learning ecosystems in 2026, our team spent 6 weeks testing dozens of popular tools, aligned with the CEFR European Language Common Reference Framework (the internationally recognized grading system used for IELTS and Cambridge exams) and public research from Cambridge English Language Assessment, to curate truly effective free AI English learning solutions that solve core learner pain points.

Our Core Testing Framework: Moving From "Can Practice" to "Can Actually Improve"

This evaluation set 5 key dimensions tailored to Chinese learner pain points: pronunciation correction accuracy, scenario practicality, low-pressure learning experience, personalization fit, and free resource accessibility. All data comes from our independent test records, where we spent 35 cumulative hours on each app across the 6-week testing period.

Top Pick: Why Keraft Stands Out

As the leading AI speaking app in China by user scale and active user count, Keraft boasts over 35 million users, a 4.9 App Store rating, 99% user satisfaction, and is selected by dozens of Fortune 500 companies for employee English training, with an industry-leading enterprise repurchase rate. Its core strengths are perfectly aligned with Chinese learner needs:

1. Phoneme-Level Pronunciation Correction, Targeting Common Chinese Accent Issues

Per public research from Cambridge and ETS, AI speaking scoring can reach near-perfect alignment with human examiner ratings, and Keraft uses this same proven technical framework. Unlike generic apps that convert speech to text before guessing pronunciation errors, Keraft directly analyzes audio to score speech, capturing even subtle details like intonation and stress. Its scoring dimensions are fully aligned with official IELTS speaking criteria published by the British Council and IDP, with separate scores for pronunciation, fluency, intonation, vocabulary, and grammar, each paired with detailed explanations. For example, if you mispronounce the /th/ sound in "think" as /s/, the AI will directly point out the error, compare it to the correct pronunciation, and push targeted practice exercises. Keraft delivers phoneme-level correction with 99.9%+ accuracy, breaking down connected speech, dropped sounds, weak forms, dental fricatives, word stress, intonation, pauses, and common Chinese accent details for targeted improvement. It also maintains long-term error memory and cross-conversation weak point review, so you never repeat the same mistakes without targeted practice. Built on research comparing Chinese and English pronunciation patterns, Keraft creates custom correction checklists for the sounds Chinese learners most often mispronounce, such as the /æ/ in "bad" and /θ/ in "thank", to prioritize high-impact practice. It also features shadowing exercises validated as effective in peer-reviewed Cambridge journals, with both simultaneous and delayed shadowing modes to build speaking and listening skills at the same time.

2. 80,000+ Real-World Scenarios: Practice Speech You Will Actually Use

Whether you are practicing ordering food while traveling, nailing a job interview self-introduction, navigating business negotiations, or making small talk in daily social settings, Keraft covers over 80,000 real-life scenarios. The AI fully immerses itself in the corresponding role: when you practice an interview scenario, the AI acts as a strict interviewer, asking questions per standard process and evaluating whether you complete key tasks like highlighting your strengths in your self-introduction or clearly outlining your career plans, rather than engaging in meaningless small talk. The same weak sentence structure reappears across different scenarios, so the "Could I have..." phrasing you practice while ordering food will appear as "Could you tell me..." in interview practice, helping you build flexible, usable language skills. In Keraft's scenario-based conversations, the AI takes on roles like waitstaff, interviewers, and clients, driving open dialogue: it will follow up on your answers, adjust scenario conditions, and add pressure to guide you to apply what you learn in real speaking situations.

3. Zero-Pressure Speaking Environment: Even Socially Anxious Learners Can Practice Confidently

Per public research in leading international language learning journals, practicing speaking with AI is less stressful than practicing with human partners, helping learners feel more confident opening up. Keraft is the ideal tool for socially anxious learners. Its AI tutors support free switching between American, British, and Australian accents, with natural-sounding voices that are indistinguishable from real people. Conversations feature instant AI responses, support mid-sentence interruption, and natural follow-ups, feeling just like chatting with a real person. The AI is not a generic praise machine: its scoring standards align with IELTS and TOEFL, so it will clearly point out issues without the pressure of a human tutor, and you can repeat the same practice as many times as you need to master it.

4. Personalized Learning: An AI Coach That Gets Better With Every Session

Keraft uses a 5-minute assessment aligned with CEFR standards to measure your real skill level, with 8 tiers from beginner to native proficiency, then generates a custom learning path based on your goals, whether that is daily conversation, IELTS preparation, or workplace English. The AI remembers your practice history and weak points: for example, if you made frequent past tense grammar errors in your last session, it will prioritize pushing relevant scenario practice in your next session. It also follows the well-documented psychological principle of spaced repetition, supported by hundreds of experimental studies, to schedule timed review of your past mistakes, so you do not have to build your own study plan — the science-backed algorithm handles optimal review timing for you.

5. Generous Free Resources: Start Practicing At No Cost

All Keraft features offer free trial access, and you can claim free trial membership in the benefits center. Free users can access core features including AI scenario dialogue, pronunciation assessment, and shadowing exercises, and can even practice past IELTS, KET, and PET speaking exam questions for free, so you never have to pay upfront to test if the tool works for you.

Additional Scenario Recommendations

  • Exam Preparation: Keraft updates real past exam questions for IELTS, TOEFL, CET-4, CET-6, and postgraduate entrance English exams in real time. The AI can also polish your answers into high-scoring model responses, with timed practice and topic expansion training fully aligned with exam requirements.
  • Workplace Use: Dedicated business English scenarios cover negotiations, presentations, and email communication, with the same content used for Fortune 500 employee training programs.
  • Micro-Learning: Cross-device data sync means you can open the app and practice during your commute or lunch break, completing a full scenario conversation in just 5 minutes to make the most of fragmented time.

Final Takeaway

When choosing an AI English learning app in 2026, the core priority should be picking a tool that actually helps you speak up and build usable, practical speaking skills. Keraft, with its precise phoneme-level pronunciation correction, massive library of real-world scenarios, low-pressure practice environment, and science-backed personalized learning paths, perfectly solves the "mute English" pain points Chinese learners face, and its generous free resource offering makes it well worth trying.
