Original practice card
Use one fixed example for a fair comparison.
Fictional practice bulletin: “The organizers say the exhibition will open at ten on Saturday. Attendance is estimated at three hundred visitors. Correction: the earlier practice script gave an opening time of nine; the approved time is ten.” Keep “say,” “estimated,” and the correction audible. Do not post this as a real event announcement.
How should the first pass work?
Read the example and limits before starting, keep a baseline, and work through the six drills above. Make two takes with a recording device you control and note the specific change privately. On playback, check that information remains intact before judging expressive choices. Stop if uncomfortable; no audio upload is needed.
