At its core, public speaking is about connection.

Whether you’re presenting to a boardroom or speaking in a team meeting, audiences are rarely listening only to your words. They are noticing your energy and whether what you’re saying feels genuine.

This is why one of the biggest paradoxes in public speaking is that the harder we try to sound impressive, the less authentic we often become.

Most of us have experienced it. We step in front of an audience and suddenly begin speaking differently. Our voice becomes more formal or we try to sound like what we think a good speaker should sound like.

And in doing so, we sometimes move further away from ourselves.

The irony is that audiences are remarkably good at sensing this. They may not be able to articulate exactly what feels different, but they often know when something doesn’t quite ring true.

This matters because people rarely connect with perfection. They connect with authenticity.

Think about some of the most memorable speakers you have encountered. Chances are, you remember less about the precise words they used and more about how they made you feel. Perhaps they inspired confidence during uncertainty or shared an experience that felt honest and human.

Why audiences trust authenticity

Trust sits at the heart of effective public speaking.

When a speaker appears authentic, audiences are more likely to believe what they are hearing. There is a sense of congruence between the message, the voice and the person delivering it.

This doesn’t mean speakers have to be perfect. In fact, the opposite is often true.

A moment of vulnerability, a brief pause to collect a thought or a small mistake handled with grace can make a speaker feel more human and relatable. Audiences tend to respond positively to people who appear real rather than rehearsed.

The actor’s paradox

As communication specialists with a background in theatre, we often encounter an interesting contradiction.

Actors rarely play themselves on stage, yet the best performances feel deeply authentic.

Why?

Because authenticity is not about saying whatever comes into your head or appearing entirely unfiltered. It is about alignment. When words, voice and presence work together, audiences experience the speaker as genuine.

The same principle applies to public speaking.

Authenticity is not the absence of preparation. In fact, preparation often creates the confidence people need to show up more naturally. The goal is  to become a more intentional version of yourself, which is where self-awareness becomes so important.

The more aware we are of how we show up under pressure, the easier it becomes to communicate in a way that feels both credible and authentic.

Confidence without pretending

One of the biggest misconceptions about public speaking is that confident speakers never feel nervous.

In reality, many experienced speakers still experience nerves before stepping in front of an audience. The difference is often that they have stopped trying to eliminate those nerves or hide them completely.

Instead, they focus on connection.

Because confidence in public speaking isn’t about pretending to be someone else. It’s about trusting that your own voice is enough.

Why authenticity matters more than ever

In a world increasingly shaped by carefully curated messages and polished online personas, authenticity has become surprisingly powerful.

People are quick to recognise when communication feels scripted or performative. Equally, they are drawn to speakers who feel genuine.

Perhaps this is why the most effective public speaking isn’t about delivering the perfect presentation, but of creating a moment of connection.

Long after the slides have disappeared and the details have faded, audiences rarely remember every word that was said – they remember how the speaker made them feel.
