Learn to Speak Fearlessly

Summary

Being good at your job and being recognized for it are two different things, and the gap between them is usually a speaking problem.

That was the premise public speaking coach Nausheen Chen brought to a DataCamp webinar on communicating with more confidence. Chen, a three-time TEDx speaker and former Fortune 500 manager at Procter & Gamble who now coaches executives at Google, Amazon, and IBM, opened by showing before-and-after clips of two former clients: a LinkedIn creator who once froze on stage and a small-business owner who stumbled through her own company introduction. Both transformed once they addressed the same three things, in Chen's telling: inner confidence, messaging, and delivery. She walked through a physiological trick for reframing nerves as excitement, a set of live exercises for cutting jargon out of a message, and a short demo, with a volunteer from the DataCamp team, on how vocal emphasis alone changes what an audience takes away from a sentence. She closed with body language guidance built around a single principle, a grounded lower body paired with visible, expressive hands, and fielded questions on how the framework holds up in settings, like interviews and auditions, where an audience really is there to judge. Her answer: shift the frame from being judged to closing a knowledge gap, regardless of the room.

Key Takeaways

• Speaking ability and job competence are separate skills; Chen argues the gap between being skilled and being recognized for it is often a communication gap, not a competence gap.
• Fear and excitement produce the same physical response (faster heartbeat, a churning stomach), which means a nervous speaker can consciously relabel the feeling as excitement rather than trying to suppress it.
• Chen's framework has three parts, in this order: inner confidence (not faked confidence), messaging (clarity and conciseness), and delivery (voice, energy, and body language), since delivery only matters once the first two are in place.
• Cutting corporate jargon ("outcome driven deliverables," "augmenting cognitive workflows") down to plain language makes a message land harder, not softer.
• The same sentence, delivered with different pacing, pausing, and emphasis, changes what an audience believes the speaker is feeling, without changing a single word.
• Visible hands on camera measurably increase how much an audience trusts a speaker, a bias Chen traces to basic threat assessment: if you can't see someone's hands, you can't confirm they're unarmed.
• When facing a genuinely evaluative audience (an interview, an audition), Chen recommends the same reframe used for a friendly one: assume the audience has a knowledge gap about your skills, and treat the interaction as filling it rather than being judged.

Why Chen Calls Speaking a "Cheat Code"

Chen opened with a claim she said most professionals never hear stated directly: "speaking well, communicating well is a cheat code to success." Her case rested on a distinction between skill and recognition. "You can have the best analysis in the room and still lose the meeting to someone who presented worse work with more confidence," she said, arguing that most people spend years mastering their actual work and zero hours learning to talk about it.

She backed the claim with her own history rather than a general appeal. Before coaching, she spent years as a filmmaker, describing herself at one point as "completely burning out," with real expertise but no visibility to show for it. "I always had to prove that I was an expert, and I was just completely exhausted," she said, describing a cycle of chasing clients rather than having them arrive. The shift came when she started posting videos on LinkedIn, not for its own sake but as a business decision. "It was an exercise in building my revenue, in building my business so that I don't need to rely on going out and finding business," she said. She became a LinkedIn Learning instructor, then got paid workshop invitations from companies including Twitch and Google.

She played two before-and-after video pairs to make the same point about her clients: an airfield-services founder who once froze on camera and later built a following of thousands, and a LinkedIn creator whose on-stage stiffness gave way to visible ease once he learned the same tools. In both cases, she said, the shift wasn't about faking a different personality. It came from separating specific, learnable habits, filler words, flat tone, closed body language, from the vague label of "confidence" people usually reach for instead. "We're talking about the symptoms here," she said. "What are the actual microhabits that you can observe?"

A Three-Part Framework: Inner Confidence, Messaging, Delivery

Chen organized the entire session around three categories she said cover every communication weakness she has ever coached a client through: inner confidence, messaging, and delivery. She was specific about the first term. "Note that it says inner confidence, not confidence, because I don't want you to just pretend that you're confident," she said. "I want you to really build your inner confidence."

The order matters, in her framing. Inner confidence comes first because a speaker who feels like an impostor will undercut even a well-built message. Messaging comes second: once the nerves are managed, the content needs to be clear and free of rambling. Delivery, voice, energy, and body language, comes last, because it's the layer an audience actually experiences. "The audience does not see your inner confidence. They don't see the hours you spent building your keynote," she said. "They only see that final delivery."

She was direct that the first category takes the longest to build and can't be rushed. "It's not possible for me to just teach you inner confidence in thirty minutes," she told attendees, framing the rest of the session as mindset shifts and specific tools rather than a finished transformation. Top-tier communicators, in her definition, "know how to build that inner confidence. They know how to structure their message, how to articulate their ideas using the right words at the right time, and they know how to deliver it with impact." Each piece reinforces the others: confidence without a clear message rambles, a clear message without delivery falls flat, and delivery without either reads as performance rather than substance.

The Physiology Trick: Reframing Fear as Excitement

Chen's central tool for building inner confidence rests on a specific physiological claim rather than a general pep talk. "Your body produces exactly the same physiological reaction to fear, so to nerves, and to excitement," she said. A racing heart, a churning stomach, and a mind that won't stop circling the upcoming event happen identically whether the underlying feeling is dread or anticipation. Since the body can't tell the two apart, she argued, the brain gets to choose the label, and that choice is available to anyone in the moment before they speak.

She illustrated the technique with her own first paid corporate workshop, an invitation from Twitch to train its female engineers, arriving just three months into her coaching business. "I was thrilled for about five seconds, and then I just felt dread," she said. As the date approached, her husband asked her a pointed question: when her own clients feel this level of stress, what does she tell them to do? Her answer was the same technique she now teaches. She walked into the bathroom, looked in the mirror, and told herself, "You're not nervous. You are excited." She recast the same facts, a new business landing a name-brand client, a chance to help other people communicate better, as reasons for anticipation instead of dread. "It absolutely works," she said.

She extended the same relabeling to specific negative thoughts rather than just general nerves. For "I'm an impostor," she suggested reminding yourself that you have something valuable to share, not something to prove. For fear of audience judgment, her reframe was more structural: "The reason why they're not judging you is because everyone is self centered, and that works for you," she said, arguing that most audiences show up with a gap in their own knowledge, not an agenda to critique. "There's a knowledge gap, which means the audience is there to learn. They're not there to judge." She said the reframe lowers the stakes of the whole interaction, which in turn makes room for the confidence to show through.

Cutting Jargon: The Test for a Clear Message

Once nerves are addressed, Chen turned to messaging, starting with a habit she said separates average communicators from strong ones: speaking on autopilot. "The speed and quality of their speech is determined by the speed and quality of their thoughts," she said of average speakers, meaning a fast, scattered thinker produces fast, scattered speech, and someone who could speak on a topic for ten minutes simply does, regardless of what the audience actually needs to hear.

She ran the group through a live translation exercise using two invented lines of corporate jargon. The first, "we're focusing on outcome driven deliverables," she asked attendees to simplify in the chat. The answer that emerged, "we care about results," drew a direct response from her: "So simple. Now you're on the same page." A second line, "this tool enhances human capability by augmenting cognitive workflows," reduced just as fast to "this tool helps you think." A third, describing a household tidying habit as "implementing friction reduction strategy in our household logistics," collapsed to "we're cleaning up and organizing so we can live better."

Her point wasn't that jargon is always wrong. In fully internal, subject-matter-fluent settings, it can work. But she said the instinct to reach for dense language usually comes from insecurity rather than precision, a way of signaling expertise rather than communicating it. "It's always about the audience," she said. "If the audience gets it, you've done your job." She applied the same logic to rambling, which she said often shows up when a nervous speaker overcompensates by over-explaining, and to filler phrases like "if that makes sense," which she said quietly damage a speaker's authority every time they're used. "That is hurting your credibility, hurting your authority," she said, noting the phrase is fine occasionally but becomes a tell when repeated every other sentence.

Voice, Energy, and Hands: What the Audience Actually Sees

Delivery, in Chen's framework, breaks into three pieces: voice, energy, and body language. She demonstrated vocal variation live with a volunteer from the DataCamp team, having him read the same sentence, "this will be the year that we finally achieve our targets," first naturally and then with a different word deliberately emphasized. The same words, said with a different stress pattern, changed what the sentence communicated. She repeated the exercise with a pair of matched lines read in two tones: "my week was insane, I had meeting after meeting after meeting," read once as exhausted and once as energized. Listeners correctly identified which reading was which every time, despite the words never changing. "I didn't change a single word," she said. "I just changed my pitch, my pacing, and my pauses. And look what a difference it made."

On body language, she reduced the entire topic to one memorable principle: a grounded lower body paired with an expressive upper body. Nervous speakers shuffle their feet or shift their weight, she said, so the fix starts with stillness below the waist. Above it, she pushed against a common instinct to hide the hands, whether under a table or out of a camera's frame. "There's actually a study that was done that shows that if we can see your hands in the frame, especially on camera, we tend to trust you more," she said, tracing the bias back to a basic survival instinct: an unseen hand could be holding a weapon. She paired that with a caution against overcorrecting into constant, meaningless gesturing, recommending gestures land only on keywords and key phrases rather than running continuously through a talk. Energy, the piece she called hardest to build on demand, she described as a decision rather than a personality trait, something to consciously raise when moving from a written task like email into a live conversation or presentation.
