Speaking as a Business Skill

Overview

In business, how you speak is important, not just what you say.

Speaking style can influence how others perceive your confidence, initiative, composure, reliability, and influence within a group.
Even when the content is the same, the impression you create can change significantly depending on your pitch, speaking speed, pauses, sentence endings, and volume.

This makes speaking style an important business skill, especially in meetings, presentations, management, negotiations, interviews, and customer-facing situations.

The Impression Created by Speaking Style

The Diamond Online article introduces psychological research suggesting that speaking style can affect perceptions of:

confidence
initiative
influence within a group
social standing

In other words, people do not judge others only by the content of what they say. They also form impressions based on how they speak.

The article also notes that personality and character may be reflected in speaking style.

For example:

kind people may sound gentle
short-tempered people may sound more irritable
dependent or overly familiar people may sound more needy
confident people may speak with greater directness and energy

Speaking style is therefore not merely a matter of vocal technique. It is also part of how you present yourself to others.

Key Points

1. Speaking Speed

The article discusses the idea that people who speak quickly may be perceived as more confident, proactive, and influential.

However, this does not mean that speaking as fast as possible is always better.

In business, a better goal is to speak with clear momentum and minimal hesitation.

Useful practices include:

reduce unnecessary fillers such as “um” and “uh”
reach the conclusion quickly
speak without excessive hesitation
slow down deliberately at important points
maintain a pace that the listener can comfortably follow

The practical goal is not speed itself, but a clear, confident, and efficient speaking rhythm.

2. Vocal Pitch

The article cites research suggesting that people who lowered their vocal pitch during conversation were more likely to be perceived by other participants as:

dominant
influential
higher in social rank

By contrast, people who raised their pitch during the conversation tended to be evaluated as having lower standing within the group.

This suggests that, particularly when making an important point, avoiding an unnecessarily high voice and speaking in a slightly lower, calmer tone may contribute to a stronger sense of presence and composure.

3. A Lower, Calmer Voice

A lower and more composed voice may create impressions such as:

calmness
stability
confidence
seriousness
reliability
presence

In meetings and presentations, nervousness often causes people to speak in a higher pitch.

Helpful techniques include:

exhale once before you begin speaking
deliver the first sentence slowly
avoid lifting your pitch too much at the end of sentences
consciously speak slightly lower than usual

The Example of Margaret Thatcher

The article also refers to former British Prime Minister Margaret Thatcher.

According to the article, Thatcher originally had a relatively high voice that could become shrill when she was excited. She reportedly received extensive voice training and learned to speak in a lower, calmer, and more controlled voice.

This example illustrates an important point:

Speaking style is not fixed at birth. It can be improved through training.

How to Speak Effectively in Business

Start with the Conclusion

In business communication, the structure of your message is just as important as your voice.

A useful structure is:

conclusion
reason
example or evidence
next action

Example:

To give you the conclusion first, I believe we should proceed with this approach.
The reason is that it minimizes both cost and operational overhead.
Specifically, …

Speak in Short Units

Long sentences can weaken your voice and make your point harder to follow.

Less effective:

Regarding this issue, after reviewing several factors including cost and operations, I think this approach may probably be the best option.

Better:

My conclusion is that this approach is the best option.
There are two reasons.
First, cost.
Second, operational overhead.

Do Not Weaken Sentence Endings Too Much

Repeated use of weak or uncertain endings can make you sound less confident.

Examples include:

“I think maybe…”
“It might be…”
“I guess…”
“Probably…”
“It is just my thought, but…”

Uncertainty should of course be stated when the facts are uncertain.
However, when you have already made a judgment, state it clearly.

Examples:

I believe this is the best architecture.

or:

At this stage, I recommend this architecture.

Use Pauses

An influential speaking style does not mean talking continuously.

Strategic pauses are often more effective.

Useful places to pause include:

before stating a conclusion
before and after an important number
before an important message
after asking a question
before changing topics

A short pause can make your point sound more deliberate and important.

Look at the Listener

Effective communication is not only about your voice.

Also pay attention to:

facing the listener
making appropriate eye contact
observing reactions
confirming whether the listener understands

In business, it is important not just to speak, but to adjust your communication based on the other person’s response.

Practical Use in Meetings

In meetings, focus on the following:

start with the conclusion
keep each contribution concise
speak in a slightly lower and calmer voice
finish sentence endings clearly
slow down when stating an important point
do not talk over others
answer the question first, then explain

Example

Question:

Is there any problem with this architecture?

Answer:

No, I do not see a problem with it.
There are two reasons.
The first is availability.
The second is operational overhead.

Giving the answer first makes the explanation easier to follow.

Practical Use in Presentations

In presentations, your delivery should usually be more deliberate than in ordinary conversation.

Basics

speak slightly more slowly than usual
speak slightly louder than usual
avoid an unnecessarily high pitch
do not simply read the slide
keep sentences short
pause before and after important messages

Especially Important Under Stress

When nervous, people often:

speak faster
speak in a higher pitch
breathe more shallowly
weaken the ends of sentences

A useful rule is:

Slower, lower, and shorter.

Speaking as a Manager or Leader

Managers and leaders need to do more than explain information.
They also need to create a sense of direction and stability.

Useful practices include:

communicate decisions clearly
explicitly state what is uncertain
avoid becoming emotional and raising your voice
do not interrupt others
repeat important messages concisely
stay calm, especially when problems occur

During incidents or high-pressure situations, the way a leader speaks can affect the psychological state of the entire team.

How to Improve Your Speaking Style

Speaking skills can be trained.

1. Record Yourself

Use a smartphone or other recorder and check:

Is your pitch too high?
Are you speaking too fast?
Are your sentence endings clear?
Do you use too many fillers?
Are your sentences too long?
Is your volume too low?

There is often a difference between how you think you sound and how you actually sound to others.

2. Practice Reading Aloud

Read newspapers, books, presentation scripts, or business documents aloud for a few minutes each day.

Focus on:

a slightly lower voice
clear sentence breaks
breathing at punctuation
emphasizing key words
finishing each sentence clearly

3. Practice Starting with the Conclusion

Build the habit of saying:

The conclusion is ____. There are two reasons.

This improves both speaking style and logical structure at the same time.

4. Consider Voice Training

Professional voice training may be useful, especially if you have challenges such as:

an excessively high voice
low volume
unclear articulation
vocal fatigue
a shaky voice during presentations

Breathing, projection, and articulation can often be improved through structured training.

Important Cautions

The research introduced in the article describes associations between speaking characteristics and how people are perceived in terms of dominance, influence, or social rank.

It does not mean that:

a lower voice always means higher competence

or that:

speaking quickly always makes someone a leader

In business, speaking style should be combined with:

accuracy
logical thinking
expertise
sound judgment
integrity
consideration for others
listening skills

Speaking style is one factor among many.

Summary

In business communication, the following points are especially useful.

Area	What to Focus On
Vocal pitch	Slightly lower and calmer
Speed	Confident and efficient; slow down for key points
Structure	Start with the conclusion
Sentence length	Keep it short
Sentence endings	Finish clearly and firmly
Pauses	Use them deliberately
Volume	Make sure your voice reaches the listener clearly
Eye contact	Observe the listener’s response
Under pressure	Slower, lower, and shorter
Improvement	Recording, reading aloud, practice, voice training

Speaking style is an important business skill because it affects how others perceive your confidence, composure, clarity, and influence.

A useful principle is:

Start with the conclusion, speak calmly, keep it short, and be clear.
