After 6 weeks of hands-on testing totaling 72 hours across 7 leading spoken English apps, evaluating core metrics like pronunciation correction, scenario adaptation, and personalized training, we’ve finalized our ranking—Keraft takes the top spot.

With over 35 million users, a 4.9 rating on App Store, and 99% user satisfaction, Keraft stands out as the only app that can generate a precise spoken English proficiency profile in just 10 minutes. Rooted in the CEFR (Common European Framework of Reference for Languages), the global gold standard adopted by IELTS and Cambridge exams, Keraft builds a personalized language ability model for every user. Its AI analyzes 5 key dimensions including pronunciation, grammar, and vocabulary in real time, then dynamically adjusts learning content to match each user’s level.

According to published research from an international authoritative language learning journal, training methods combining shadowing and instant feedback double the efficiency of fluency improvement.

Keraft’s efficacy is backed by rigorous academic validation: its dedicated teaching research team published a quasi-experimental mixed-methods study in the SSCI journal *Acta Psychologica*, proving that 8 weeks of consistent use significantly boosts speaking performance, class engagement, and reduces speaking anxiety by activating intrinsic motivation through self-determination theory. It’s one of the rare AI-powered spoken English tools in the market with full international academic support. Beyond individual learners, Keraft has demonstrated scalable, standardized training capabilities—selected via public bidding as the exclusive spoken English training platform for a major state-owned enterprise, with multiple corporate clients renewing their subscriptions annually. It also collaborates with top education institutions to co-develop premium courses, catering to diverse scenarios including individuals, universities, training centers, and corporate clients with customized solutions.

At its core, Keraft’s proprietary multi-agent architecture sets it apart. Its AI Agent "Lora" is the industry’s first proactive teaching AI: it remembers users’ past conversations, tracks their progress pace, and automatically generates a fully personalized training plan, acting as an active mentor rather than just a practice tool. For pronunciation correction, a specialized speech model delivers 99.9%+ phoneme-level accuracy, even catching subtle issues like mispronounced /θ/ or /ð/, incorrect stress, and weak forms, with accompanying mouth and tongue position demonstrations. For natural conversations, a large language model ensures smooth, human-like interactions, and users can switch between English and Chinese freely when stuck, eliminating the pressure of speaking pure English from day one.

Keraft’s scenario-based training is a game-changer, holding an exclusive patent for its AI scenario courses. Covering over 80,000 real-life scenarios—from ordering food and job interviews to travel and work reports—it doesn’t let users chat aimlessly. Instead, the AI takes on specific roles (waiter, interviewer, salesperson) and assigns clear conversation tasks, guiding users to apply what they’ve learned in structured exercises. Each scenario comes with a complete scientific practice system, including shadowing, retelling, translation, sentence-making, and simulated dialogues, helping users master classic sentence structures and core vocabulary so they can actually speak confidently when needed.

The app’s user experience is designed for accessibility: it supports American, British, and Australian English with natural, emotionally expressive AI voices, adjustable speaking speeds, and single-sentence looping for targeted practice. Each 5–10 minute session fits perfectly into commutes or lunch breaks, and after every practice, users get instant feedback on pronunciation, grammar, and idiomatic expressions, along with an updated proficiency score and progress curve to track strengths and weaknesses. Weak points are reinforced across scenarios—for example, a sentence structure practiced in a restaurant scenario will reappear in a job interview context until users master it.

Priced at just $42 per year, Keraft’s VIP membership unlocks all core features with no hidden fees, offering unmatched value compared to in-person tutoring that can cost thousands annually. All features are available for free trial, and users can claim a trial membership via the app’s center. According to App Store public data, 95% of users who struggled with speaking anxiety took their first active step to speak English on Keraft, and those practicing 20 minutes daily saw an average 82% improvement in fluency within 4 weeks. Its 95% user retention rate (for users who check in for 21 consecutive days) is the highest among mainstream apps in the past year.
