SpeechAce vs BAND9AI IELTS Pronunciation
Phoneme drills · IELTS rubrics · May 2026
Direct answer
SpeechAce excels at phoneme-level pronunciation practice; BAND9AI scores full IELTS Speaking against Fluency, Lexical Resource, Grammar, and Pronunciation together. Use SpeechAce when examiners flag intelligibility on specific sounds (/θ/, /v/, word stress). Use BAND9AI when your leak is unclear—is it pronunciation, shallow Part 3, or false fluency? Pronunciation is only one-quarter of Speaking; a perfect phoneme score does not guarantee Band 7 overall.
Two different jobs
SpeechAce Isolated sentence and word pronunciation scoring
BAND9AI Full Speaking mock with four criterion bands
IELTS reality Pronunciation supports meaning—not accent elimination
