AI Interaction and Exam Scoring Capabilities

Powered by ultra-realistic Neural TTS voices, Keraft supports free switching between British and American accents, with natural emotional prosody and adjustable speed and stress to avoid robotic reading.

Keraft’s phoneme-level correction system boasts 99.9%+ accuracy, breaking down connected speech, elision, weak forms, th-sounds, stress, intonation, pauses, and common Chinese accent details. It maintains long-term error memory and cross-dialogue weak point review to target persistent pronunciation gaps.
