Four real numbers, captured from your actual voice
Accuracy, Fluency, Overall Pronunciation, Prosody — what each one measures, and why the bar isn't what you'd assume.
Four numbers behind your delivery feedback
Accuracy, Fluency, Overall Pronunciation, and Prosody (stress, intonation, rhythm) — all four captured live from your actual recording, not guessed from a transcript.
Why the bar isn't 90
Thresholds are deliberately calibrated down: 85-100 is clear and natural. Testing showed even genuinely native, clearly delivered speech doesn't reliably clear 90 on a single short clip.
A real delivery score
78 / 100 Accuracy
= generally clear — nothing to fix.
When Prosody lags behind Accuracy
Your sounds were correct, but stress, intonation, or rhythm came out flat — work on the music of a sentence, not the sounds themselves. A word flagged below 50 is the real signal; natural reductions like "mornings" regularly land in the 55-69 range even for fluent native speakers.
A flagged word, in context
"mornings" flagged at 62
Normal native reduction — not an error worth fixing.
Delivery is one piece, not the whole score
These four numbers only feed your Fluency score. Coherence, Language Use, and Topic Development are graded from what you actually said — a clear voice with a thin answer still won't score well, and a slightly rough voice with a well-developed answer can still score high.
