A School of Continuous Improvement paper adopts the Voice-Note Duration Envelope as the minuting rule for spoken contributions, with no chair's override.
A household survey of how long the thumb stays on the mic becomes the speaking-time specification
Eight seconds is as short as a household voice note usually gets, and forty-seven and a half is as long as most listeners will stay. That interval, taken from family, school-parents, neighbourhood, and share-house group chats, is now the speaking-time specification for Improvement Grand Rounds.
Dr Solveig Adeyemi, Lecturer in the School of Continuous Improvement, with Dr Thandiwe Solberg, Senior Lecturer and Convenor of Demo Quarter, and Associate Professor Casimir Beng, Lead of the Adaptive Metrics Lab, surveyed 1,847 adults and asked a diary subsample of 214 to log 6,108 voice notes over twenty-one days. Duration is reported as a distribution: family chats cluster near sixteen seconds, school-parents chats split between a short drop-off ping and a two-and-a-half-minute recount, neighbourhood chats carry a long tail, and share-house chats hug the floor. The Voice-Note Duration Envelope is the pooled twentieth-to-eightieth percentile of that diary.
The School of Continuous Improvement has put the household waveform on the Grand Rounds clock.
A voice note is a report that arrives already timed. The minutes only have to keep the ones that fit.

The Envelope withholds the minute from any spoken contribution that falls outside 8.0 to 47.5 seconds, with no chair’s override. Across the first four sessions, mean turn length fell from seventy-one seconds to twenty-two; eleven turns were padded up from below the floor and nine were clipped down from above the ceiling. Dr Solberg noted that “a slot that can be too short as well as too long is a different kind of slot,” and that Demo Quarter will watch the same interval without yet adopting it.
