How Fast Should You Speak?
Slower isn’t smarter and faster isn’t sharper. The research says something more useful than either.
One skill: Finding your landing rate
Every speaking guide says “slow down.” So here’s an inconvenient study: researchers who varied speakers’ rates found that faster talkers were rated more credible and more persuasive, speed read as competence and conviction. Should you speed up, then? Also no. Both one-word answers are wrong, and the real answer is more interesting.
Two curves, one sweet spot
Rate pulls two levers at once. Impression rises with fluent speed, Norman Miller’s field experiments found fast speakers judged more knowledgeable, and later work by Smith and Shaffer confirmed brisk delivery can boost persuasion. But processing falls: listeners decode meaning phrase by phrase, and past a threshold, comprehension quietly drops while your credible-sounding words stop landing.
Put together: the optimum isn’t slow. It’s as fast as your clearest articulation survives, energetic enough to carry conviction, spacious enough that every phrase gets decoded. And crucially, the number isn’t constant: dense or unfamiliar content needs a slower gear than a story your listener can coast through.
Vary the gear, not just the speed
- Cruise on the familiar. Stories, examples, context: take these at your natural brisk pace. This is where speed buys energy for free.
- Downshift for cargo. Numbers, names, the key claim: drop a gear exactly there. The contrast itself flags importance, a constant pace, fast or slow, is what actually loses people.
- Never outrun your articulation. The moment word-endings start smearing, you’ve passed your ceiling, whatever the wpm says.
- Mistake to avoid: slowing everything down after feedback. Uniformly slow speech doesn’t read as thoughtful; it reads as padded. Pace variation is the skill; slowness is just one gear of it.
✗ One gear
“(everything at 190 wpm, including the only number that matters)”
✓ Geared
“(the story at speed…)”
“…and the figure is (three) million.”
Your turn
The gearbox drill
Take one minute on something you know: yesterday, your work, a film.
- Speak the context at your natural fast pace: don’t police it.
- When you reach the single most important sentence, halve your speed for just that sentence.
- Return to cruise. Notice how the slow sentence now sounds like the headline it is.
Practice it for real
You need your actual number, everyone’s guess about their own rate is wrong in the direction of flattery.
- Record a 60-second answer and open the report’s Articulation row: your measured pace, against the band listeners process comfortably.
- Re-record the same prompt with one deliberate downshift on your key sentence.
- Compare how the two replays feel at the moment that mattered.
Key takeaways
- Fast fluent speech genuinely boosts credibility, and quietly taxes comprehension. Both findings are real.
- The optimum is the fastest rate your clearest articulation survives, not “slow”.
- Vary gears: cruise through stories, downshift precisely on cargo, numbers, names, the claim.
- Uniform slowness reads as padding; contrast is what reads as command.
Cheat sheet
The Gearbox
- No magic number
- The ceiling is where articulation starts to smear.
- Cruise
- Stories and context at natural speed, energy is free.
- Downshift
- Numbers, names, the claim: one gear lower, right there.
- Contrast is the message
- A pace change flags importance by itself.
- Beware uniform slow
- It reads as padding, not thoughtfulness.
