central
19.7% omitted
Central is the key modifier marking this as the central hall, but it sits at the front and is easily dropped when the speaker rushes ahead.
Practice: Say central clearly first — it fixes which hall — before moving on.
The word most easily wiped out here is the one that fixes which hall: central tops the list at 19.7%, followed by two unstressed the forms (13.7% / 12.9%). Across 466 attempts speakers kept 73.2% and scored 3.46/5 — lose central and 'the central hall' collapses into a generic 'hall'.

Each word is shaded by how often it was dropped across 466 attempts. Hover for the exact rate. This sentence is one case in the Listen and Repeat research across 23,000+ sessions — where endings and late words drop most.
The three most fragile words here are central (19.7%), the (13.7%), hall (12.9%) — when you record your own version, check first that each of these survives.
These are sounds with substantial measurements in this sentence, not a generic pronunciation list. Automatic assessment places /z/ lowest among the sounds shown.
| Sound | Measurements | Avg accuracy | Below 60 |
|---|---|---|---|
| /z/ | 1,122 | 74.5/100 | 28.6% |
| /k/ | 569 | 80/100 | 17.8% |
| /s/ | 528 | 85.1/100 | 10.8% |
Omission rates show the pattern, not its cause. Position, word length, and endings still give us specific practice hypotheses to test.
