Warming Up Your Voice Before an Interview

Watch a set of interviews back to back and you notice something dull and consistent. A lot of first stations are worse than the same candidate's fourth. Not because the question was harder, but because it was the first time they had used their voice properly that day.

Singers, actors and lawyers all warm up before they perform, and none of them think it is precious. Applicants almost never do, and then spend station one clearing their throat, starting sentences twice and speaking at about seventy per cent of their normal volume.

It is five minutes of work. Here is the version worth doing and the mistakes that make people skip it.

What actually goes wrong in station one

Three things at once. Your volume is set from the last conversation you had, which was probably a quiet exchange in a waiting room, so you start too soft and stay too soft. Your breath is high in your chest from nerves, so sentences run out of air and end in a mumble. And your articulation is cold, so consonants get lazy and the assessor works harder to follow you than they should.

None of that is a content problem, which is why it is infuriating. You lose ground in the domain marked communication for reasons that have nothing to do with what you know.

It matters more in a circuit than in a single seated interview, because there is no gentle opening. As our overview of what an MMI is in Australia and New Zealand explains, each station is typically scored independently by a different assessor, so a rough first station does not get averaged away by a strong recovery. Check the university's current admissions page for how they run theirs, but the general principle holds: the first minutes count as much as the last.

The five minute warm up

Do this about thirty to sixty minutes before your first station, somewhere private. In order, roughly a minute each.

• Breath. Stand up. Breathe in for four, out for eight, six times. Long exhale, no force. This drops your breathing out of your shoulders, which is where nerves put it, and it is the part that fixes sentences running out of air.
• Hum. Gently, lips closed, up and down through your comfortable range for thirty seconds or so. You are aiming for a slight buzz in your lips and nose. Never push for volume or reach for notes that feel like effort.
• Loosen. Yawn twice on purpose. Roll your shoulders back. Move your jaw side to side. A clenched jaw is the single most common tension in a nervous applicant and it flattens everything you say.
• Articulate. Any consonant heavy phrase, said slowly and deliberately five times, then quickly. Red leather yellow leather is the classic for a reason. It feels ridiculous and it works within about twenty seconds.
• Speak in full sentences. Talk out loud for sixty to ninety seconds about anything you know well: what you did yesterday, the plot of something you watched. Not an interview answer. You are warming the machine, not rehearsing.
• Set your volume. Say two sentences at the level you would use to be clearly heard across a room. That is your interview volume, and it will feel about twenty per cent too loud. It is not.

The last step is the one that transfers most. Nearly every candidate who is told they were hard to hear was speaking at a volume that felt perfectly normal from the inside.

Where to do it when there is nowhere to do it

You will not be humming in a waiting room full of other applicants. Realistic options: in the car on the way, which is the best one available and covers everything; walking the last ten minutes to the building, on the phone to someone or apparently on the phone to someone; a bathroom cubicle for the breathing and the articulation; or at home before you leave, if the travel is short.

If your interview is online, you have no excuse at all, since you are alone in a room. Do the full five minutes, and do the last two after you have joined and muted yourself, not before you sit down.

One physical point worth mentioning: warm up in what you will wear. A collar or a jacket that restricts your shoulders changes your breathing, and you would rather discover that at home. Our guide to what to wear to a medical interview has the practical side of that, and the rule for voice is simple: nothing tight across the ribs or the throat.

Things that make it worse

Shouting to warm up. It is not a warm up, it is a strain, and a tired voice in station six is a real cost.

Clearing your throat repeatedly. It feels productive and it is irritating tissue that is already dry. Swallow, or sip water, instead.

Talking constantly in the waiting room. Nervous chat with six other applicants burns your voice and your composure at the same time, and it is where the comparison spiral starts. Say hello, be pleasant, then go quiet.

Adding an extra coffee because you feel flat. Whatever you normally have is what you should have. Interview morning is a bad time to change a dose of anything.

And rehearsing answers as your warm up. It sounds efficient and it is the wrong tool, because it drags you back into content anxiety at exactly the moment you want your attention on your body.

Voice does more work in roleplay

In an ethics or motivation station, your voice carries content. In roleplay it carries the relationship. Pace, warmth and the willingness to drop to a lower volume when someone is upset are most of what makes a candidate feel safe to talk to, which is exactly what our guide to MMI roleplay stations describes those stations as testing.

A cold voice defaults to fast and flat, which reads as brisk, which reads as not really listening. That is a poor mark earned by physiology rather than by attitude, and it is completely avoidable.

Build it into practice, not just the day

Do the warm up before every practice session as well, so that on the day it is a familiar routine rather than a new ritual you are attempting under pressure. If you are running timed stations with MasterMed's live AI interviewer, warm up first and then start the clock, exactly as you would in a real circuit. The first speaking station is free on the trial, no card, and the trial never converts by itself.

There is a secondary benefit that people notice more than the vocal one. Five minutes of breathing and speaking gives you something to do with the twenty minutes before an interview, which would otherwise be spent reading notes you already know and getting steadily more frightened. Having a routine is worth as much as having a warm voice.
