Why this matters

Voice mode lets you speak to ChatGPT instead of typing. Two minutes of rambling out loud gives it better raw material than a tidy paragraph.

The 20-minute experiment

1. 1Open the ChatGPT phone app and tap the waveform icon at the right of the message box
2. 2Say the prompt below out loud first, so it knows to stay quiet
3. 3Talk for two minutes about a problem you're chewing on. Don't tidy as you go
4. 4End the call, then ask in text: 'Summarise that into three points and one next action'

I am going to ramble. Do not interrupt. Afterwards, give me the three arguments I actually made.

• Voice conversation started
• You spoke for roughly two minutes without stopping
• Summary produced with three points
• At least one point is something you hadn't written down before
