Listen to a person's voice before you listen to their words, and you'll often learn more. The pitch someone speaks at, the way it rises or drops, and the small filler words they hang onto — these are the parts of speech most people never think to control. That's exactly why they're worth paying attention to.

Pitch and tone: confidence lives in the lower register

A low, steady voice tends to read as confident and grounded. When someone speaks to you in a calm lower register, the impression they create is one of self-assurance and a certain quiet authority. It doesn't sound like they're trying to convince you of anything — and that lack of effort is itself persuasive.

A high pitch carries a different signal. When the voice climbs and the volume goes up, it usually means the person feels challenged, agitated or defensive. Raised pitch is the body's way of saying it has lost a little of its composure. Neither register is good or bad on its own; what matters is the shift. A voice that suddenly jumps higher in the middle of an otherwise calm conversation is telling you something has touched a nerve.

I want to be careful here. Tone reveals a pattern, not a verdict. Some people are naturally soft-spoken; others are simply loud by temperament. You read the change against a person's own baseline, not against a stranger's. Watch how their voice behaves when they're relaxed, then notice when it drifts away from that.

Filler words and what they give away

The other thing I always listen for is fillers — the "okay," "you know," "so," "actually," "basically" that pepper unprepared speech. The number of fillers a person uses is a soft indicator of how ready they are for the conversation they're in.

When someone is stacking up a lot of fillers, it often means they haven't fully organised their thoughts. They're buying time mid-sentence. In a business or financial discussion, that's useful to notice — a person who isn't prepared is easier to read and harder for them to bluff. On a date or a casual meeting, the same thing reads differently and rather sweetly: someone fumbling for words usually isn't performing a rehearsed version of themselves. The unpolished version is the honest one.

The "okay" habit — and why it works on you

There's one filler I'd ask you to drop from your own speech, and that's the habitual "okay" some people tag onto every sentence. "I'll send it tomorrow, okay? We'll meet at five, okay?" When you keep ending statements with "okay," you're quietly inviting the other person to agree with you over and over. Each small "okay" trains them to nod along. It can feel agreeable, but it weakens how your words land — you sound like you're seeking permission rather than stating something.

So the lesson cuts both ways. Listen to other people's fillers as a clue to their preparation and ease. Then listen to your own, because the crutches you don't notice are shaping how seriously you're taken.

Putting it together

None of these cues works alone. A low voice with no fillers and steady eye contact tells you one story; a high, rushed voice full of "you knows" tells you another. Read them as a cluster, against the person's own normal way of speaking, and you'll start to hear meaning in places most people only hear noise.

  • Low, steady tone: usually confidence and control.
  • High, rising pitch: feeling challenged or defensive.
  • Many fillers: often underprepared or thinking aloud.
  • Habitual "okay": weakens your own authority — let it go.

The voice is the most overlooked part of body language because we can't see it. But it's working on us all the time. Once you start listening for it, you don't switch it off.
