How they sound: speaking style how? →

236 words/min while actually speaking · 23.3 um and uh per 1k words · 17.2 false starts per 1k · 30.7% of pauses land inside a clause

Measured by listening to the audio itself: 10,698 words across 1 episode of raw-level tape, transcribed verbatim with every um and uh kept, each one attributed only where the alignment onto our timed stream is unambiguous. These are measurements of speaking style. We do not rank them: across this corpus, fluency and argument quality are nearly uncorrelated (ρ≈0.2), and smooth talking does not signal clear thinking.
