Public Speaking Tips for Podcasters Making Their Guest Debut

1. The Pre-Recording Warm-Up Routine

A podcast warm-up serves two purposes: getting the voice into its working range, and getting the nervous system out of fight-or-flight. The exercises below come from broadcast journalism training and voice coaching practice.

Voice warm-ups (5 to 7 minutes)

Lip trills are a common warm-up across singing, voiceover work, and broadcast training. Press your lips loosely together and blow air through them so they vibrate, like a horse snort. Add a tone, then glide that tone up and down a comfortable pitch range. Humming on a "mmm" sound does similar work for resonance. The University of Maryland's Robert H. Smith School of Business includes resonance tuning in its seven-minute warm-up. The exercise shifts vocal focus from a nasal buzz to a fuller chest-dominant sound. Tongue twisters wake up the articulators (lips, teeth, and tongue). "The tip of the tongue, the teeth, and the lips" is a classic from broadcast training. "Red leather, yellow leather" works a different muscle group. Three repetitions of each, slow then fast, is enough.

Body warm-ups (3 to 5 minutes)

Roll the shoulders forward and backward five times each. Open the jaw wide and let it hang for a count of five. Massage the cheek muscles in slow circles. Australian voice coach Nic Redman, who works with broadcast presenters, recommends a full-body shake before voice gigs: arms, legs, and face. The shake releases tension that would otherwise show up in the throat. Posture changes the voice. Sitting upright with feet flat on the floor allows for easier breath support.

Breath work (2 to 3 minutes)

Diaphragmatic breathing is the technique most voice coaches build on. Place one hand on the chest and one on the belly. Inhale through the nose for four counts and feel the belly expand without much chest movement. Exhale through the mouth for six counts. Slow, controlled breathing steadies the voice before speaking.

Hydration and food choices

Room-temperature water is preferred by most voice coaches. Dairy and heavy meals leave the throat feeling coated and make breathing less comfortable while speaking. Most voice coaches recommend avoiding both before a recording.

The full routine takes about 15 minutes. For guests with a packed schedule, a stripped-down version (lip trills, diaphragmatic breathing, and one tongue twister) takes under five minutes.

2. How to Structure Answers on a Podcast

The SOAR framework, adapted for stories

SOAR (Situation, Obstacle, Action, Result) is a behavioural interview framework that translates cleanly to podcast storytelling.

The structure runs about 60 to 90 seconds when delivered out loud:

1. Situation (10 to 15 seconds): Set the scene with one specific detail, like a year, a number, or a name.
2. Obstacle (10 to 15 seconds): Describe the problem you faced and what made it hard.
3. Action (30 to 40 seconds): Walk through what you did, with at least one decision point that surprised you or required a trade-off.
4. Result (10 to 15 seconds): Share the outcome and what changed afterward.

The headline-first answer for opinions

For a question that asks for your view rather than a story, lead with the opinion in one sentence, then back it up. Example: "I think a lot of B2B SaaS companies are over-investing in content marketing right now. Here's why." The structure mirrors how journalists write a news lead and gives the host a clean handle for follow-ups. Buried opinions, where the speaker builds to the point through three minutes of context, often get cut in the edit.

Prepare three to five anchor stories

Behavioural interview trainers recommend keeping a working document of stories with notes on which traits each one demonstrates: leadership, resilience, technical depth, conflict resolution. The same approach works for podcast guests. Three to five anchor stories, each tagged with the questions they answer, gives you a redirect when an answer stalls.

What does not work is memorising answers word for word. The cadence of a memorised answer is detectable on audio. It locks you into a rigid response that ignores how the host phrased the question.

3. Voice Techniques for Podcast Audio

Talk past the microphone, not into it

Most cardioid microphones used in podcasting sound better when positioned slightly off-axis, angled to the side of your mouth rather than pointed straight at it. The angle reduces popping on plosive consonants like p and b without needing a pop filter. Position the mic around four to six inches from the corner of your mouth.

Smile when you start each answer

This sounds odd but is documented across radio and broadcast training. A smile changes the shape of the vocal tract and adds warmth to the tone. Listeners can hear a smile without seeing it.

Vary pitch on emphasis words

Roger Love, voice coach to Tony Robbins, Brendon Burchard, and Bradley Cooper, teaches what he calls melody in speech. The technique runs counter to the flat, neutral tone many professionals default to. Move pitch up on emphasis words and down on the closing word of a sentence.

A simple drill: read a paragraph aloud and underline the two most important words in each sentence. On a recording, push those words slightly higher in pitch. Replay and compare it to a flat read of the same paragraph.

End sentences with a downward inflection

Uptalk, where the pitch rises at the end of declarative sentences, often reads as uncertainty on audio. The fix is to consciously drop the pitch on the final word of each statement. A drill that works for many speakers: read newspaper headlines aloud while exaggerating the downward fall on the last word.

Skip the verbal acknowledgments

In face-to-face conversation, listeners signal attention with verbal acknowledgments like "right," "yeah," and "uh-huh." On a podcast, those overlap with the host's voice and create chaos in the edit. Nodding visibly and silently is enough.

4. How Do You Handle Podcast Anxiety?

Speaking anxiety is extremely common, particularly when the recording feels permanent. A few research-backed techniques make it manageable.

Reappraisal: "I am excited" rather than "I am calm"

Harvard Business School professor Alison Wood Brooks ran a series of experiments published in the Journal of Experimental Psychology: General in 2014. Participants who told themselves "I am excited" before a high-pressure performance produced measurably better outcomes. Those who told themselves "I am calm" did not match those results.

The effect held across karaoke singing, math problems, and public speaking. The mechanism: anxiety and excitement produce similar physiology (elevated heart rate, faster breathing, sweating). Reframing the same physical state as positive is easier than trying to suppress it.

The first-90-seconds reframe

Stanford communication lecturer Matt Abrahams hosts the Think Fast Talk Smart podcast. His research shows that anxiety symptoms peak in the opening minute or two of a speaking situation. They then fall as the body adapts. Knowing this in advance reduces the loop where a guest panics about being nervous, which makes them more nervous. Treating the first 90 seconds as a known rough patch, rather than a permanent state, makes them easier to ride out.

5. What to Do When You Don't Know the Answer

Most podcast anxiety centres on one fear: being asked something you cannot answer.

Prepare for the questions you dread, not just the ones you expect

Alison Wood Brooks, speaking on the HBR IdeaCast, recommends writing down every question you dread before the interview. Preparing a written response to each one forces you to confront the discomfort in advance. A guest who has worked through those answers in writing before the interview rarely freezes when the host asks live.

For each question on the dread list, write one of two things: a direct short answer, or a redirect to related territory. The hosts most likely to push on difficult questions are those with the most engaged audiences. Finding the right podcasts for your niche before you commit helps you gauge how challenging the interview is likely to be.

"I don't know" is a usable answer

Brooks noted on the same episode that admitting ignorance, used sparingly, functions as a credibility move rather than a credibility loss. Bluffing through an answer the host or audience can fact-check is more damaging. A response that works: "I don't know the exact figure, but the pattern I have seen is X." That gives an honest scope to your uncertainty while still contributing something.

Do not speculate, and say so

Guessing and framing it as analysis is worse than saying you don't know. A guess creates a specific claim that can be wrong. Media training experts agree: incorrect speculation damages credibility more than admitting uncertainty does. When a host pushes for speculation, "I'd rather not speculate on that without better data" is a complete answer.

7. Common Podcast Guest Mistakes

Filler word stacks

"Um," "uh," "like," "you know," and "so basically" tend to cluster. Reducing them takes practice. A common drill: record yourself answering one question for three minutes, then count the fillers on playback. Many speakers see a significant drop within two weeks of self-auditing this way.

Excessive hedging

Hedged phrasing softens claims to the point where they no longer carry information. Stating a view directly lands harder.

Talking over the host

In face-to-face conversation, gentle overlap is normal. On audio, overlapping voices create messy edits. Wait a half-second after the host finishes a question before starting your answer.

Podcast performance improves with repetition. The first appearance is rarely the best one. Guests who listen back, identify two or three habits they want to change, and apply those notes to the next recording move fastest.

If you are preparing for a first appearance, run the warm-up, pick one story to structure as SOAR, and let the rest come naturally. If you have done several episodes and want to improve, listen back to the last one and address the two habits that bother you most. Preparation does not remove nervousness. It converts it.

8. Frequently Asked Questions

How do I stop being nervous before a podcast recording?

Reframe nervousness as excitement rather than trying to suppress it. Harvard Business School research shows that telling yourself 'I am excited' outperforms 'I am calm' because both states share the same physiology. Run the 15-minute warm-up routine in this guide and treat the first 90 seconds of recording as a known rough patch, not a permanent state.

How long should podcast answers be?

Target 60 to 90 seconds per answer. The SOAR framework in this guide is calibrated to hit that range naturally. Shorter and the host runs out of follow-up questions; longer and you lose the conversational rhythm that makes podcast listening work.

What should I do in the 15 minutes before recording a podcast?

Run the pre-recording warm-up: five minutes of voice work (lip trills, humming, a tongue twister), three minutes of body loosening (shoulder rolls, jaw drops, a full-body shake), and two to three minutes of diaphragmatic breathing. Have room-temperature water ready and close all background applications before joining the call.

How do I reduce filler words when speaking on a podcast?

Record yourself answering one question for three minutes and count the fillers on playback. Most speakers reduce their count noticeably within two weeks of regular self-auditing. A deliberate pause sounds considered; a filler sounds uncertain.

Do I need to memorise my answers before a podcast interview?

No. Memorised answers have a detectable cadence that sounds rehearsed on audio. Prepare three to five anchor stories using the SOAR structure and know the shape of each one, not the exact wording.

What microphone should a podcast guest use?

Any USB condenser microphone beats a built-in laptop microphone. Common options include the Audio-Technica ATR2100x, Rode NT-USB Mini, and Blue Yeti. Position it four to six inches from the corner of your mouth, slightly off-axis, to reduce plosive popping on consonants like p and b.
