Nerves are a situation, not a personality trait
It is worth being precise about this, because the language people use about themselves gets in the way of fixing anything. "I'm a nervous person" is a statement about who you are. "I get nervous in interviews" is a statement about a situation. Only the second one is actionable, and the second one is almost always the accurate description.
The evidence is in your own life. Most people who describe themselves as bad at interviews can explain their work clearly to a colleague or answer a hard question in a meeting without their pace collapsing. The capability is intact. What changes in an interview is the context: you're being evaluated, the stakes are concrete, the other person's reactions are hard to read, and you have no idea what's coming next. That combination produces a physiological response, and the response is what shows up in your delivery.
This matters because the two framings lead to different preparation. If nerves are a trait, there's nothing to do but hope you grow out of it. If they're a response to an unfamiliar, high-stakes, unpredictable situation, the lever is obvious: make the situation less unfamiliar and less unpredictable. That is what rehearsal actually does. It doesn't make you a calmer person — it removes one of the three ingredients.
What nerves actually do to your delivery
Nervousness is not a single effect. It's a cluster of them, and they interact — which is why a nervous answer often sounds worse than any one of its parts.
- Pace rises. The most consistent and most visible effect. Speaking faster shortens the exposure — some part of you works out that the sooner the answer ends, the sooner the discomfort ends. But listeners read speed as anxiety or under-preparation, and fast speech is genuinely harder to follow, so the content lands less well too.
- Fillers multiply. "Um", "uh", "like", "you know" appear when the sentence you've started outruns the plan you had for it. Under pressure you start sentences sooner and plan them less, so the gap between speaking and thinking widens — and gets filled with sound.
- Restarts increase. You begin a sentence, decide mid-way it isn't the right one, and start again. One restart is invisible. Four in a row makes an answer sound uncertain even when the underlying point is sound.
- Breathing goes shallow and high. The one people notice least and that drives the most. Shallow breathing gives you less air per sentence, pushing you to hurry to the end of each one, which raises the pace, which shortens the breath further. It also thins the voice — that tighter sound you hear back on a recording and don't recognise as yours.
These compound. Shallow breathing pushes pace up; higher pace means less planning time; less planning time means more fillers and restarts. Which is good news, because you don't have to fix four things — slowing the breath takes the pressure off the other three at once.
Why your feedback can look worse than the answer felt
People are frequently surprised by their first set of results, in both directions — some feel calm and see 190 words per minute, others feel like they fell apart and get a perfectly reasonable read. The mismatch is normal, and it's the main reason recording yourself is worth doing at all. Your internal experience of an interview is largely invisible to the other person. What they get is the output: the pace, the pauses, the words. Neither reading is the "real" one, but the external one is the one the interviewer has.
Preparation that actually helps
Three things reliably move the needle, and none of them are about "staying calm" — which is not a skill anyone can execute on command.
Rehearse out loud, not in your head. The single largest difference-maker and the most commonly skipped. Reading your prepared examples silently trains recognition; it doesn't train production. Speaking is a motor skill, and the first time you say a sentence aloud is genuinely the first time — whether that happens in your bedroom or in the interview is your choice. Say your key examples out loud, start to finish, including the bits you fumble. Fumbling in rehearsal is the entire point.
Arrive early enough to stop rushing. Physical hurry and vocal hurry are the same state. If you've sprinted from a car park or spent ten minutes worrying about a connection dropping out, you begin the first answer already breathing at the top of your chest. Ten unhurried minutes beforehand removes that. For a remote interview, test the camera, microphone and link the day before as well as on the day, so the last thing you do before speaking isn't troubleshooting.
Take the pause before answering. When a question lands, the instinct is to start talking immediately, because silence feels like failure. It isn't. Two or three seconds to decide which example you're using and how it ends is not awkward from the other side of the table — it reads as considered, and it's the cheapest structural improvement available to most answers. It also breaks the compounding cycle above before it starts, because the pause gives you one full breath and a plan. If you want a phrase to buy the moment, "let me think about that for a second" costs you nothing.
All three are things you can only build by doing. Veracue puts you in the situation deliberately: real questions from a real job description, answered on camera, with feedback on the pace, fillers and eye contact you can't observe in yourself while you're speaking.
When it isn't nerves
Everything above is about situational nervousness. It is not about speech and fluency conditions, and the two shouldn't be conflated.
If you have persistent concerns about your speech fluency — ones that show up across many settings rather than only under pressure, or that have been part of your speaking for years — that is a matter for a speech pathologist, not a practice tool. A qualified clinician can assess what's actually happening and work with you properly. No amount of rehearsal substitutes for that, and an app measuring pace and filler counts is not equipped to tell the difference.
And to say the obvious thing plainly: a stutter is not a delivery flaw. It isn't a sign of nerves, poor preparation, or lack of confidence, and it isn't something to be fixed before you're allowed to interview well. People who stutter interview well and are hired constantly. Whether you mention it to an interviewer is entirely your call — some find it takes the pressure off, others would rather not, and both are reasonable. Requesting adjustments, such as questions in advance or extra time, is legitimate and something many employers will accommodate.
