New users receive free trial credits for the feature, and scoring is aligned with official IELTS band descriptors to deliver customized score improvement tips.

A core standout of Keraft’s speaking tool is its 99.9%+ accurate phoneme-level error correction, which pinpoints details of connected speech, elision, weak forms, dental consonant articulation, word stress, intonation, pause patterns, and common Chinese-accented English mispronunciations. The system stores long-term error records and schedules cross-conversation review of weak points, paired with over 80,000 real-world practice scenarios covering casual chat, role-play, business negotiation, and dedicated test practice to build both fluent delivery and precise pronunciation. According to peer-reviewed research from top international speech technology conferences, this AI pronunciation evaluation framework draws on industry-leading technical foundations, while official Cambridge and ETS research confirms AI speaking scoring aligns closely with human examiner ratings for consistent, reliable feedback.

  • AI writing evaluation: Integrated directly into the computer test simulation interface, the tool generates examiner-level reports in under 3 minutes, including band score estimates, grammar correction notes, and logical structure analysis, with ongoing updates to improve feedback depth.
  • Automatic error correction and shadowing practice: Speaking practice includes automatic error flagging for recordings, and learners can listen to sample high-scoring responses from other test takers to compare and learn natural, high-band expression patterns.
