Speaking tips

We separate advice backed by research or official university guides from rules of thumb that are widely repeated.

Researchconfirmed in papers / university guidesRule of thumbwidely said, weak evidence for numbersCautionoften misused
⏱
Conversational pace

About 140–170 words per minute. Rushing doesn't land.

⏸
Turn “um” into silence

Silence isn't scary. Stopping to think looks confident.

👀
Look at the room

Looking up has been linked to fewer fillers.

🖐
Only purposeful movement

Pacing, swaying and waving your hands distract people.

🎥
Record and review

Your own habits are hard to notice.

1Voice

ResearchUse a conversational speed as your baseline

A peer-reviewed paper recommends practicing at a conversational 140–170 words per minute. With a diverse audience, go a little slower.

IN HITOMAECheck the Pace meter and the coach's “too fast” hints.
Rule of thumbSet your volume for the back row

Even without a mic, aim your voice at the last row. Use plenty of breath and hold it to the end of each sentence.

Rule of thumbVary your pitch on key words

A monotone puts people to sleep. Change pitch around conclusions and numbers, and say the conclusion lower and slower.

2Pauses

ResearchReplace fillers (um, uh) with silence

Breaking content into small chunks makes it easier to stop silently. Aim for no more than one or two per minute (university presentation guides).

Rule of thumbPause 2–3 seconds around key points

It signals “this matters.” It works especially well right before a number. Stop for a beat at the end of each sentence so people can catch up.

IN HITOMAEYour script shows “⏸ pause” and “⏸ 2 s” suggestions.

3Eyes, posture, gestures

ResearchLook at your audience

Eye contact has been reported to go along with fewer fillers. Meet people's eyes one at a time, for a second or two each.

ResearchOnly purposeful movement

Pacing, swaying and over-gesturing distract the audience (university presentation guides).

Rule of thumbCount numbers on your fingers, show ranges with your hands

Hold up three fingers for “three points.” Match words and movement — gestures only where they help.

4Opening & closing

Rule of thumbFor the first 20 seconds, look at the room — don't read the title

Look around and pause for a second before you start. Speak a little lower and slower than usual.

Rule of thumbState your takeaway first

“Today you'll take home three things” keeps listeners from getting lost.

Rule of thumbClose slowly, looking at the room

Don't rush the last line. Thank the audience and bow or nod.

5Slides

Rule of thumbOne message per slide. Don't cram text

If you read your slides aloud, people read along instead of listening. Say what isn't on the screen.

Rule of thumbBefore a hard part, say “you don't need to remember this”

Lowering the load keeps people focused.

Rule of thumbAudiences understand slower than you talk

Give people time to look at a figure before explaining it — a constant theme in conference advice.

6Nerves

Rule of thumbEveryone gets nervous. Use it instead of fighting it

Warm up your voice, breathe out slowly, and memorize just your first sentence. If you slip, don't stop — take a beat and carry on.

ResearchRecord yourself and review

University guides suggest checking your speed on a recording and reviewing twice: audio only first, then video.

!Caution

CautionThe “7-38-55 rule” doesn't apply to ordinary talks

It comes from experiments where words and feelings contradicted each other. Using it to claim “looks are everything” is a misuse.

This app's measurements are rough guides

Pace is estimated from loudness peaks, not words per minute. Posture, eye contact and gestures are estimates from camera pose tracking. Not for medical or grading use.

Presentation tips

Remember these when you talk in front of everyone!

📣
Big voice

Talk so the person in the very back can hear you!

🐢
Talk slowly

If you talk too fast, people can't hear you.

😮‍💨
Take a breath

Instead of “um,” just stop and breathe.

👀
Look at everyone

Lift your head and look at the audience.

☝️
Count on your fingers

“I have three things” — show three fingers!

🙇
End with a bow

Say “Thank you for listening” slowly.

1Starting

Look at everyone and smile

Before you begin, take a slow breath.

Remember your first line

If you can say “Hello, everyone. My name is ___,” you're off to a great start!

2While you talk

Pause at the end of each sentence

A tiny stop at each period helps everyone understand.

Change your voice for important parts

If your voice never changes, people get sleepy. Say important words strongly.

Mistakes are OK

It's fine to stop. Take a breath and keep going.
