You Know Your Stuff – So Why Doesn’t It Sound Like It?

Introduction

Your boss asks you a question on the spot and, despite knowing the answer, you stumble over your words. You talk about something you know well, but end up over-explaining, repeating your point, or sounding less certain than you feel. You go to share an opinion, then your mind goes blank and the words disappear.

Sound familiar?

These situations highlight a frustrating and common gap experienced by many communicators –  the disconnect between knowing something and expressing it clearly in the moment.  

This article outlines why this gap happens, and how specific communication patterns can either support or undermine how your knowledge is perceived.

Limitations of Sounding Uncertain 

These communication breakdowns are not only frustrating, they can  limit clarity, connection, and opportunity. When your message isn’t clear, others may misunderstand instructions, miss key points, or feel overwhelmed in conversation. Over time, this can impact how often others engage with you and how much they rely on your input.

Unclear communication also shapes perception. You may have the experience and knowledge required for a role, but if you cannot express it clearly and confidently, particularly in high-stakes situations like interviews, you may be overlooked.

In many professional settings, people aren’t evaluating what you know, they’re evaluating how clearly and confidently it comes across.

When speech is disorganized, wordy, repetitive, or filled with hesitation, a monotone tone, or fading volume, it can signal uncertainty – even when your understanding is strong.

Organization and Language

When done well, the words you choose, how many you use, and how your ideas are structured all contribute to how your competence is perceived. Clear, organized and intentional language use makes your message easier to follow and trust.

Tips

• Consider your audience 
  • Strong communication reflects not just what you know, but how well you tailor . Adjust your language based on your listener’s level of familiarity. Do they know formal terminology or do they require a more simplified explanation? 

• Don’t overuse higher-level language
  • Find a balance between using language that demonstrates knowledge in the area but not so much that it clouds the overall message. Clarity trumps complexity. 

• Stay with one idea at a time
  • Develop your idea fully before moving on. When you do move on, transition to a loosely related topic. 

• Comment on what the other person said 
  • Knowledge and professionalism isn’t just about expressing what you know, it’s also about demonstrating a desire to learn and hear from others 
• Don’t clutter your sentences
  • Consider the key ideas, then build from there.

When your ideas are disorganized or overly complex, it can create the impression of uncertainty, even when understanding is strong.

Detail and Dilution

There’s a fine line between explaining enough and explaining too much. When you over-explain or repeat yourself or add unnecessary detail, your message becomes diluted and less impactful. Over-explaining risks losing your audience’s attention, and with it, their understanding. More information doesn’t always lead to better understanding. Often, it has the opposite effect.

Tips: 

• Trust your listener to ask for more if needed
  Instead of anticipating every possible question, allow space for follow-up.
• Limit how much your share at once
  Aim for 1-2 key points before pausing or checking-in 
• Answer questions directly
  Focus on the question at hand without adding additional detail 
• Avoid repeating the same idea in different ways
  Trust that what you’ve said once is enough. Repetition can reduce clarity rather than reinforce it 

Example:

Question Posed: What are the key findings from the data?

Overly Detailed Response:  “So I was working on this part of the project which took me forever, which I didn’t anticipate. I had to put another task aside to do this but that task is simple and I’ll get to it later.  When I was looking at the data last week I saw some inconsistencies and a lot of results surprised me but nothing really notable. There was a lot of data which is good, it took a while to go through, I even needed two coffees to stay focused. There must be a better way to do this.”
What’s happening here:

• Does not clearly answer the question 
• Includes irrelevant details 
• Repetitive and unfocused 
• Main point is unclear 
• Lengthy response

Well Balanced Response: “There are two main findings. First, there were some inconsistencies in the data. Second, while several results were unexpected, none were significant. I have specific examples if it’s useful”

What’s happening here:

• Opens with clear structure and sets expectations 
• Clearly answers the questions
• All detail is relevant and on-topic 
• The response is direct and succinct 
• Leaves space for follow-up instead of overloading

When too much detail is shared all at once, the key message gets lost, making to harder for your knowledge to come across clearly.

Tone

Tone communicates engagement, intent and confidence. Even if your ideas are clear and well- structured, a flat, inconsistent or mismatched tone can make you sound disengaged, uncertain or less knowledgeable than you are. Tone helps signal what matters and how your message should be received.

Tone communicates confidence, engagement, and intent. Even when your ideas are clear and well-structured, a flat, inconsistent, or mismatched tone can make you sound uncertain, disengaged, or less knowledgeable than you are.

Tone helps signal what matters and how your message should be received.

Tips

• Speak with varied intonation
  • Using a monotone voice can be interpreted as uninterested, knowledgeable and can lose the audiences attention 
• Ensure your tone matches the intended mood
  • Are you excited, sad, angry, confused? Ensure it’s clear through your voice 
• Choose emphasized words wisely 
  • Consider what it is you want the listener to understand – add emphasis to the words that support this. You can say the exact same sentence 5x and it mean something different each time 
  • Example: Statement: I want a new red car
    • Focus on it being a certain colour: I want a new red car
    • Focus on it being new: I want a new red car 
    • Focus on it being a car: I want a new red car
  • Notice how the meaning shifts depending on what is emphasized.

Your tone signals confidence, intent, and what matters most in your message.

Pacing

How fast you speak and  how confident you sound are strongly aligned. Rushing through your sentences may come across as nervousness and that you want to ‘get it over with’. Rushing also reduces the impact as it limits the listener’s processing time. Speaking quickly may also increase the frequency that you repeat yourself or say the ‘wrong thing’. Speaking faster than your brain, often leads to fillers (um and uhs) which will make you sound even less confident and knowledgeable. People often believe speaking quickly is necessary especially in fast-paced working environments. But often, you have to repeat yourself anyways, so you may as well take the extra few seconds in the first place.

Tips

• Your brain and mouth should be aligned
  • Allow time for your brain or organize your thoughts. Slowing your speech may also help slow down your thinking speed if it feels too quick – particularly helpful for the ADHD brain 

• On average say 140 words per minute (WPM)
  • Use a voice-to-text software while timing yourself. Paste it into a Word document, go to ‘tools’ and see how many words you said. If it’s over 1 minute, take the average (Example for 2 minutes: 315 words/2 = WPM 

• Ensure you’re breathing around every 8-10 words
  • When you’re out of breath, you’re forced to rush due to needing oxygen.  

• Take up space
  • Speaking slower demonstrates that you’re confident that what you say has value and that you know you deserve to take the time to say it

Pausing and Silence

Sitting in silence is one of the most challenging things for speakers to do, but it can also be one of the most impactful.

Not all silence is equal. There’s a difference between pausing and hesitating.

• Hesitation often sounds unstructured (fillers, uneven timing, mid-sentence breakdowns)
• Pausing is intentional and placed – it adds clarity and emphasis

A well-placed pause communicates that you are thinking, not struggling.

Pausing gives you time to organize your thoughts and choose your words more deliberately. It also signals control, calmness, and intention which communicates  that you care about what you say and how it’s received.

Just as importantly, pausing supports your listener. It gives them time to process what you’ve said, follow your ideas more easily, and recognize what matters

Tips 

• Pause within and between sentences 
  • Don’t just wait for a natural pause (i.e punctuation) to stop, use pauses to shape your message.  
• Pause long enough to feel deliberate 
  • Some pauses could be longer than others depending on the impact you want. Regardless of the impact, pauses should give you enough time to take a supportive breath.
• If you don’t know what to say, pause 
  • Jumping into speech and hoping for the best often leads to breakdowns. Sit in silence to collect and organize your ideas.
• Pause methodically 
  • Pausing before you speak helps you organize. Pausing after you speak helps your message land.
• Breathe when you pause 
  • Breath supports the fullness of your voice and calms your nervous system which supports language processing 
• Use pauses to highlight key words
  • Use pausing to signal that something important was just said, or is about to be said.
  • Example:
    • Read the following aloud.
      • “There’s value in answering the question first before adding additional information.”
    • Now read it again:
      • Pause after “first”
      • Add emphasis to “first”
    • Notice how the pause:
      • clarifies the structure
      • reinforces the main idea
      • makes the message more engaging

Often, how you sound shapes perception just as much as what you say.

Breathing

Breath is the foundation of a clear, confident voice.

Without adequate breath support, your voice can lose fullness and consistency. Speech may feel more effortful, leading you to rely on tension in your throat rather than efficient airflow. This often results in reduced volume, vocal fatigue, and a voice that fades at the end of sentences.

Breathing also supports language. Taking a moment to breathe allows for better thought organization, word retrieval, and more controlled pacing.

Breath is not separate from communication – it drives it.

Tips:

• Breathe long enough
  Inhale for at least 1.5 seconds, then speak right away (while we speak we are breathing out). This gives you the support needed to maintain volume and complete your thought without rushing
• Breathe deeply and efficiently
  Primary movement during an inhale is the diaphragm expanding like a balloon.Avoid lifting the shoulders or relying on shallow chest breathing.  Be sure to breathe in through your mouth during speech.
• Breathe frequently enough
  On average, take a breath every 8 -10 words. Even if only a few words remain, it’s often better to pause and reset than to push through without support
• Coordinate breath with pausing
  Optimize on natural and methodical pauses to inhale. This supports both vocal strength and language organization.

Breath supports the strength, consistency, and ease of your voice.

Self-Correcting

Saying ‘sorry’ as a way to correct what you said reduces your own confidence, both in how you feel and how you come across to the listener. You don’t need to apologize for saying the wrong word or mumbling through your sentence. Instead, take a pause, breathe, then use the phrase “or rather” 

Say these two sentences aloud. How does it feel to say each?

a) I want to go to the park, sorry I mean the store.

b) I want to go to the park, or rather, the store.

When I say each, I feel a bit of panic during the first sentence, compared to a sense of control and calmness in the second. This is how we should feel while we’re communicating – no matter the topic or context.

The impact of using ‘sorry’ when self-correcting can also carry forward into what you say next. You may feel the need to speak quicker or worry about ‘messing up’ again – which will likely make it harder to speak effectively and confidently.

How you recover from small breakdowns can either reinforce confidence, or undermine it. 

Conclusion

Knowledge alone doesn’t guarantee opportunity, how it’s communicated does.

When your communication is clear, structured, and intentional, your ideas don’t just exist, they land. And when your ideas land, your competence becomes easier for others to recognize and trust.
