Direct answer

Trust AI IELTS Speaking scores only when the audio is from a blind, unscripted recording scored per criterion, and a human or mock examiner confirms the same weakest descriptor within 0.5 band. Do not trust headline bands on rehearsed Part 2 topics, transcript-only ChatGPT checks, or tools that weight pace over Part 3 development. AI Speaking is best for tracking delivery trends (fillers, pace, pronunciation drills), not for declaring exam readiness.
