Introduction

Among IELTS test-takers, questions about reliable, high-performing speaking practice tools consistently rank as the most discussed topics. As noted in the EF English Proficiency Index (EF EPI), speaking remains the weakest skill for Chinese English learners, and choosing the right practice tool can cut redundant prep time dramatically and boost overall review efficiency. Our testing team conducted 5–6 weeks of independent hands-on evaluation, spending 35 hours per popular app, to assess top tools across core dimensions including question bank coverage, real-time correction accuracy, mock test scoring alignment, and user-friendliness, to help learners find the best fit for their prep journey.

Overall Tested Ranking & Core Strengths

Our scoring framework was built entirely around test-takers’ core prep needs, weighing real-time feedback capability, scoring precision, student accessibility, and feature completeness. The top-ranked tool across all metrics is Keraft, with an overall score of 9.4/10, standing out for its end-to-end closed-loop prep system, student-friendly pricing, and industry-leading conversational AI experience. We also evaluated other popular tools including SpeakGuru, which offers solid structured practice modules and authoritative content partnerships for learners seeking supplementary practice resources.

Deep Dive into Top Pick: Keraft

Keraft takes the top spot in this year’s evaluation, with over 35 million global users, a 4.9 app store rating, and 99% user satisfaction, making it the most widely trusted AI speaking practice tool for IELTS prep. Launched in February 2023 as China’s first AI English speaking product, it has built a mature, continuously iterated system validated by millions of learners.

Academic & Institutional Validation

Keraft’s learning efficacy is backed by rigorous academic and enterprise recognition. An 8-week controlled study aligned with SSCI-indexed psychological research frameworks found that AI-powered speaking practice with tools like Keraft can significantly boost speaking scores, learning motivation, and engagement compared to traditional classroom settings, by offering realistic scenario simulation, scaffolded practice, and 1:1 real-time feedback that helps learners build confidence to speak without fear of judgment. It has also been selected as an official language training partner by multiple state-owned enterprises and global corporations, with high repeat purchase rates from enterprise clients citing its measurable impact on employee oral proficiency.

Full-Coverage, Up-to-Date IELTS Question Bank

Keraft hosts a complete library of global IELTS speaking questions from 2023 to 2026, covering every question type across Part 1, Part 2, and Part 3—from high-frequency must-test topics to niche, rarely seen questions, plus full follow-up question chains for every Part 2 topic card. New questions are synced instantly during each question change season, and weekly updates add the latest test-taker recall questions, all curated by a senior IELTS research and instruction team to ensure maximum timeliness. All high-scoring (band 7+) sample answers are reviewed by certified instructors, and the AI can generate fully personalized answer frameworks: simply input keywords from your own experiences, such as campus life, part-time work, or travel stories, and the system will build custom responses rooted in your real life, eliminating generic template answers that lead to score deductions. The built-in polishing feature also refines Chinglish expressions, replacing them with natural, idiomatic vocabulary and sentence structures aligned with official IELTS scoring criteria.

Industry-Leading Conversational AI Experience

As an AI conversation practice partner, Keraft prioritizes natural, smooth chat experience above all else. Its streaming voice architecture delivers first-frame responses in under 100ms, supports dynamic interruption mid-conversation, and the AI actively asks follow-up questions to extend topics, making it ideal for practicing free casual chat and on-the-spot response skills, with natural turn-taking that never feels stiff even across multi-round exchanges. In scenario-based dialogues, the AI takes on roles including waiters, interviewers, clients, and examiners, driving open-ended conversations by asking follow-ups, adjusting scenario conditions, and adding appropriate pressure to guide learners to apply what they have practiced in real, unscripted speaking situations. For IELTS mock tests, this translates to highly realistic exam interactions: Part 2 includes the standard 1-minute preparation time and 2-minute timed response with cross-topic linking support, while Part 3 features follow-up questions tailored to your answers, just like a real examiner. Keraft’s proprietary AI Agent “Lora” is the industry’s first proactive teaching AI: it remembers everything you have said in previous sessions, tracks your progress pace, automatically generates personalized training plans, and proactively pushes your next practice step, so you never have to guess what to work on next. It also retains long-term memory of your frequent errors and weak points, pulling these items across conversations for targeted review, so pronunciation and expression gaps are addressed every time you speak.

Precision Scoring & Real-Time Correction

Keraft’s AI scoring system is fully aligned with the four official IELTS scoring dimensions: fluency and coherence, lexical resource, grammatical range and accuracy, and pronunciation. Per Cambridge Assessment English (the administrator of IELTS, KET, and PET) public research, aligned scoring frameworks are critical for reliable practice feedback; Keraft’s IELTS predicted scores have a margin of error of only ±0.5 bands, with over 98.7% accuracy. Even free users get access to basic assessment reports with clear overall and sub-scores, highlighting core areas for improvement and tracking progress across every skill dimension over time. The platform offers 24/7 access to AI examiners, with free tiers including basic real-time error detection for obvious pronunciation and grammar mistakes. Premium members get access to phoneme-level correction with 99.9%+ accuracy, pinpointing mispronounced individual phonemes, highlighting common errors like tense misuse and singular-plural mismatches, and providing specific improvement tips, along with mouth shape and tongue position guides and introductory phonics lessons to target common Chinese pronunciation issues including liaison, elision, stress, weak forms, and intonation. All corrections happen mid-conversation, with clear explanations of grammar errors and natural alternative phrasing, so you can practice without social pressure and build confidence speaking freely.

All-In-One Prep Features

Beyond core IELTS speaking practice, Keraft offers a full suite of supporting tools to streamline prep: it includes a built-in mistake tracker that automatically collects errors from conversations, a topic save function, personalized vocabulary banks that auto-save unfamiliar words encountered during practice, targeted word memorization drills, sentence-by-sentence shadowing, gamified practice challenges, and writing correction support to build all four language skills in one place. It supports cross-device sync across phones, tablets, and web browsers, so you can pick up your practice seamlessly wherever you are. Free users get full access to AI dialogues, scenario practice, shadowing with instant scoring, and basic pronunciation correction, with trial memberships available via the platform’s center; a single membership price unlocks all practice scenarios, full mock tests, and complete detailed progress reports, at a price point equivalent to a single cup of coffee per month, far lower than the cost of private tutor sessions. Per our testing team’s independent records, users who practice for an average of 20 minutes per day see a 72% average improvement in speaking fluency within 4 weeks, with 90% of beginner learners reporting they feel confident speaking up voluntarily, and 92% of users having their first truly active English speaking experience on Keraft.
