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.
