Four Speaking Skills That Actually Work (Even for Introverts)
Jessica Chen, a Columbia University instructor, shares four transformative communication principles: stop trying to impress and focus on what others need to hear; master vocal tone and delivery as much as content; treat public speaking as a trainable skill using deliberate practice; and build strategic visibility by consistently staying top-of-mind rather than waiting to be noticed.
Shift from Impressing to Connecting
Stop Using Armor of Bravado
Early in her TV career, Jessica tried to sound impressive by speaking robotically, using technical jargon, and loading everything with data. Her boss pulled her aside and advised her to simplify her points, revealing that this approach was actually preventing connection rather than building credibility.
The Curse of Knowledge
Once you deeply understand something, you lose the ability to imagine what it's like not to know it. This causes you to skip steps, assume context, and speak in ways that assume everyone already follows your logic—exactly what Jessica's boss was pointing out.
Two Pre-Meeting Questions
Before any important conversation, ask: (1) What do the people in this room already know? (2) How can I share my points in a clear and concise way? This reframe shifts focus from proving yourself to serving your audience's actual needs.
Master Tone and Delivery
Words Are Only a Small Part
The words you say are a small fraction of communication. What matters far more is how those words feel when they land—the delivery determines whether people lean in or tune out.
Five Elements of Tone
Tone comprises five trainable elements: pitch (how high or low your voice is), intensity (how loud or soft), rate (how fast you speak), inflections (which words you emphasize), and voice quality (the unique resonance people recognize as you). Modulating these elements can completely change how a message lands.
Research: Vocal Variation Increases Persuasion
A 2014 study in Psychological Science found that intentional vocal variation made speakers measurably more persuasive and memorable—even when the content was identical to a monotone delivery. Modulation alone, with the same words, completely changed impact.
Treat Public Speaking as a Trainable Skill
Warren Buffett's 50% Value Increase
Warren Buffett identifies public speaking as the one skill that can increase your value by over 50%. Public speaking is not an innate talent but a learnable skill that compounds career success.
Self-Audit Your Presentations
Watch yourself present and audit what you're doing: Why did you rush? Why lose eye contact? Where did energy drop? Which sentences landed? This honest self-assessment is the foundation for improvement.
Make One Small Improvement at a Time
Rather than overhauling everything, commit to one deliberate change per presentation (e.g., 'I will speak slower than I think I need to'). Use visual reminders like post-it notes. Results compound consistently over time.
Deliberate Practice: Quality Over Quantity
Psychologist Anders Ericsson's decades of research show that top performers (musicians, chess players, surgeons) don't just practice more—they practice specifically with focused, feedback-driven repetition. It's the quality of practice, not the hours, that builds expertise.
Self-Modeling Through Visualization
Research on self-modeling shows that visualizing yourself as a great speaker changes how you perceive yourself. When you start to see yourself differently, you perform that way, and that becomes who you actually are.
Competitive Advantage Through Speaking
Most people avoid public speaking, so becoming excellent at it immediately positions you above your peers. Being seen as a presenter signals you're not only good at your job but articulate—a secret sauce to career success.
Build Strategic Visibility
The Thunderbirds Story: Visibility Matters
Jessica raised her hand for a coveted opportunity to fly with the US Air Force Thunderbirds, but her manager gave it to colleague Bella instead. When asked why, he said Bella 'kept talking about it and was top of mind'—even though Jessica had mentioned it once. This taught her that visibility, not just quality work, determines opportunities.
Stop Waiting to Be Noticed
For years, Jessica believed hard work and quality would speak for itself. She watched colleagues who weren't smarter or harder-working get ahead because they actively made themselves visible. Waiting to be noticed is a passive strategy that fails.
Visibility Is Strategy, Not Vanity
Research by Adam Grant and Wharton shows that the most influential people at work consistently share knowledge, stay enthusiastic, and share ideas—not to show off, but to stay connected and relevant in decision-makers' minds.
The Five-to-Seven Repetition Rule
Cognitive psychology research shows people need to hear information five to seven times before it resonates. Following up and building visibility isn't annoying—it's how human memory works. Repetition is necessary, not excessive.
Say It Multiple Ways, Consistently
Say your message in an email, a meeting, a hallway conversation, a follow-up—not the same way each time, but consistently enough that people know who you are, what you stand for, and what you want. This keeps you top-of-mind for bigger opportunities.
The Four Transformations Summary
Four Core Principles
Jessica's journey to confident communication involved four unlearnings: (1) Stop trying to sound impressive; focus on what others need. (2) Recognize that how you say something matters as much as what you say. (3) Treat public speaking as a trainable skill, not a talent. (4) Build strategic visibility instead of waiting to be noticed.
No Loudness Required
None of these changes required Jessica to be louder, more aggressive, or someone she wasn't. They required being smarter in approach—which is exactly what her book 'Smart Not Loud' teaches.
Notable quotes
I know you're smart and hardworking. It would really help if you could just simplify your points. — Jessica's boss
Public speaking is not talent, it's a skill. And like any skill, it can be practiced, studied, and improved. — Jessica Chen
She kept talking about it and she was top of mind. — Jessica's manager (explaining why Bella got the opportunity)
Action items
- Before your next meeting, write down: (1) What does this audience already know? (2) How can I say this more clearly? Use this to simplify your message.
- Record yourself giving a presentation and audit it: Where did you rush? Where did you lose eye contact? Which sentences landed? Pick one element to improve next time.
- Practice one deliberate vocal change in your next presentation (e.g., speak slower, lower your pitch, or soften your intensity). Use a visual reminder like a post-it note.
- Identify one key message or opportunity you want to stay top-of-mind for. Share it in at least five different ways over the next month: email, meeting, hallway chat, follow-up, conversation.
- Stop waiting for your work to speak for itself. Commit to making yourself visible by consistently communicating what you want and what you've accomplished.
