How it works

Practice, in private. Improve, on purpose.

No coach to book, no camera to face. Three minutes, and you know exactly what to work on.

01

Record an answer

Speak for thirty seconds, or run a full mock interview by company and role. It’s just you — nothing is uploaded.

02

Get judgment-free feedback

A clear read on your confidence, clarity, delivery — and, in interviews, your actual answer — with the one thing to fix first.

03

Practice and watch it climb

Short guided reps with live feedback, a path that adapts to you, and a score you actually see move.

What Corie coaches

Four things that decide how you land.

Corie measures how you come across — never who you are, and never your accent.

Confidence

A grounded, steady voice that reads as sure — instead of nervous or rushed.

Clarity

Words that land crisply and carry. We score how clearly you’re understood — never your accent.

Delivery

Pace, pauses and energy — the rhythm that keeps a room with you instead of losing it.

Answers

In mock interviews, what you actually said — scored on structure, specifics and ownership against the STAR rubric.

Talk back · Pro

Two conversations that decide things — out loud.

Not a form to fill in. A real back-and-forth: the AI asks, pushes back, and goes the distance — then scores what you said and how you held up.

One take. One clear fix.

Start the interview

Private by design

Every recording is analyzed on your device and discarded the moment your score is computed. Nothing is uploaded — ever.

Six vocal signals

Pitch, steadiness, pace, pauses, clarity and energy — measured on every take.

Scored on STAR

Mock-interview answers graded on structure, specifics and ownership.

An adaptive path

Rebuilds each day around the signals your own voice shows are weakest.

Fair for non-native speakers

Corie scores clarity — how clearly you’re understood — and never your accent.

Most people rehearse what to say. The ones who walk out with the offer have rehearsed how it lands.

Built for your moment

Whatever you’re walking into.

Corie tailors questions, drills and prompts to the situation you’re actually preparing for.

Software engineering

Talk through a project or a system-design curveball without rushing or trailing off.

The science

How you sound shapes how you’re heard.

Decades of research show your voice moves trust, leadership and persuasion — often before your words register. Corie trains the exact signals that research measures.

0.5seconds
All it takes for a listener to judge your trustworthiness — from a single “hello.”
McAleer, Todorov & Belin · PLoS ONE, 2014
Lowerreads as leader
People pick leaders with lower-pitched voices — men and women alike — reading them as more competent.
Klofstad, Anderson & Peters · Royal Society B, 2012
Pacemoves persuasion
A quicker, steady pace is rated more persuasive and more credible than a slow, hesitant one.
Miller, Maruyama, Beaber & Valone · JPSP, 1976
“um?”reads as unsure
Rising, question-like endings and filler words make listeners judge you as less certain.
Brennan & Williams · J. Memory & Language, 1995
Trainablewith reps
Pitch range, stress and intonation measurably improve with structured practice and feedback.
Review · Int’l J. Speech-Language Pathology, 2009
You≠ the recording
You’ve never heard the voice everyone else hears. Psychologists call the shock “voice confrontation” — and it’s exactly what to train against.
Holzman & Rousey · JPSP, 1966

These studies describe how listeners perceive voices in general — they’re not a guarantee of personal results. Corie measures the acoustic signals this research describes, on your device.

Why trust it

Proof, not promises.

The research Corie is built on — and guarantees you can hold us to.

“Listeners form an impression of your trustworthiness within half a second of hearing you speak.”
Finding · McAleer, Todorov & Belin, PLoS ONE 2014
“Voices judged more competent and dominant tend to be lower in pitch — and people vote for them.”
Finding · Klofstad et al., Royal Society B 2012
“Intonation, stress and pitch range improve measurably with structured practice and feedback.”
Finding · review, Int’l J. Speech-Language Pathology 2009
Private by design

Practice like no one’s watching. Because no one is.

The most honest feedback is the kind only you see. Your audio is analyzed in your browser and discarded the moment you’re scored — it’s never uploaded, never stored, never used to train anything.

FAQ

Good questions.

Do I need to sign up to try it?
No. The free voice check works with no account — record, get your score and your #1 fix. You only make an account if you want to save your history and unlock the full trainer.
Is my voice uploaded anywhere?
No. All analysis runs in your browser, on your device. The audio never leaves your machine and is discarded the moment your score is computed.
What does Corie give feedback on?
Your delivery — pitch depth, steadiness, pace, pauses, clarity and energy — and, in mock interviews, what you actually said, scored on the STAR rubric. It never judges your accent.
How is this different from recording myself?
A recorder shows you a waveform. Corie tells you what’s holding you back, why it matters, and exactly what to do about it — then trains the fix with guided reps and tracks whether it’s working.
Is it fair to non-native English speakers?
Yes. Corie scores clarity — how clearly you’re understood — and never penalizes your accent. It’s built to help with high-stakes English, not to flatten how you sound.
What does it cost?
The voice check is free forever. The full trainer — an adaptive path, an AI coach after every take, the full gym, saved history and scored mock interviews — is $49/year (about $4.08/mo) or $12/month. Cancel anytime, with a 7-day money-back guarantee.

Your next interview can be the second time.
