Episode #34: Should I Memorise Or Read My Presentation Content

Why do great written speeches fail in real life?

A speech can be brilliantly written and still completely miss the mark. That happens when the talk is designed for reading, not for listening. If your audience could get the same value from an email, your “speech” isn’t a speech — it’s a document.
Mini-summary: A speech succeeds through live connection, not perfect wording.

People focus when they feel the speaker is real. Authenticity beats polish. A speaker who looks at the audience, reacts to them, and speaks from the heart creates attention — even if the delivery isn’t flawless. Slides can help, but only as a guide, not a script.
Mini-summary: Eye contact and authenticity create attention more than eloquence.

Should you memorize your speech word-for-word?

Most speeches are too long to memorize well. The effort is huge, the risk is high, and memory failure on stage is brutal. Memorization is only worth it for short, highly formal occasions — like wedding speeches in Japan or ceremonial greetings where fixed phrasing matters.
In Japan (日本, Japan), certain formal events require protocol language. When content must be exact, memorization may be necessary — but that’s the exception.
Mini-summary: Memorize only short or ultra-formal speeches; otherwise, don’t.

What can go wrong when you memorize?

Even experienced leaders can blank out mid-speech. One moment of unexpected applause, emotion, or distraction can break the memory chain. On a big stage, a blank mind feels endless — and the audience feels it too.
Mini-summary: Memorization increases the chance of a painful mental “whiteout.”

Sometimes you have no choice — legal statements, technical announcements, crisis media comments, or formal messages on behalf of a senior leader. If you must read, you can still deliver powerfully:

• Learn the text deeply so you can glance and speak, not bury your face in the page.

• Read the first part of a sentence, then deliver the ending while looking at your audience.

• Add gestures to reinforce meaning.

• Stand tall and project confidence.

• Pause to let key points land.

• Emphasize critical words and vary your voice so the message feels alive.

Mini-summary: Even with a script, delivery skills can keep you connected.

What’s the best way to deliver most business speeches?

For nearly all business situations — leadership updates, sales talks, project briefings, keynote stories — a conversational style works best. Use speaking points, not full sentences. Talk to the points, not at the text. Read your audience, not your script.
If they look puzzled, clarify. If they lean in, expand. Communication is a two-way exchange, even in a one-way format.
Mini-summary: Speak from key points in a natural, audience-responsive way.

Why does authentic delivery matter for leadership in Japan?

In Japanese companies (日本企業, Japanese companies) and multinational firms (外資系企業, multinational/foreign-affiliated companies), employees respond to leaders who feel human and credible. Perfect grammar isn’t the goal. Connection is.
When leaders speak authentically, people trust them, remember them, and feel inspired — which shapes performance, engagement, and culture.
Mini-summary: In Japan’s business context, authentic delivery builds trust and engagement.

• Great writing cannot rescue poor delivery — audiences want connection.

• Memorization is risky and rarely necessary for business speeches.

• If reading is required, strong delivery techniques preserve credibility.

• Conversational, point-based speaking creates trust, attention, and impact.
