Speech coach in your pocket
Speak for 30 seconds. Get the sentence that lost the room, the filler count, and the one thing to fix next. Not a grade. A note you can act on before the meeting.
Listening

In about ten seconds
Clarity, flow, structure, substance and delivery, scored separately. A 6.2 overall tells you nothing. A 4.1 on structure tells you what to practise tonight.

The part people pay for
The exact sentence where you lost the thread, what to say instead, how many fillers and where they cluster. It reads like notes from someone who was listening.

When practice gets boring
Same prompt, same clock, judged side by side, ELO on the line. It is the reason people come back on day nine instead of day two.
It is the shape the research keeps pointing at. Short, spaced, and fed back on. The reason most people never improve at speaking is not effort, it is that nobody is in the room to tell them what went wrong.
Deliberate practice research is consistent on this: repetition alone stops producing gains once you are competent. The feedback is the active ingredient, and it is the part solo practice never has.
Ericsson, 1993
Spacing the same total practice across more days produces materially better retention than massing it. Thirty seconds daily is not a compromise on an hour weekly. It is the better shape.
Cepeda, 2006
