Most people have never heard how they actually sound. Record thirty seconds and Corie scores your voice across six acoustic signals — depth, steadiness, pace, pauses, clarity and energy — then shows you the one thing to train first.
Voicemaxxing is training how your voice sounds on purpose, instead of leaving it to chance. The internet is full of vibes and bad advice. Corie makes it measurable: a score you can move, and drills backed by voice science.
How grounded you sound. Train toward the lower, steadier end of your natural range — measured in Hz so you can watch it move.
Lower pitch → leader · Klofstad, Royal Society B 2012
Whether your pitch holds its line instead of wobbling or rising into a question at the end.
A warmer, more forward tone and crisp consonants that actually cut through.
People form an impression of your voice in under a second — and unlike a lot of "looksmaxxing," this part is genuinely trainable.
How you sound is one signal among many — and one you can actually change. This is about being heard as the most capable version of you, not chasing a "perfect" voice.
A score is step one. Corie's gym has evidence-based drills — the kind voice clinicians and coaches use — each with a live metric and a personal best you can beat.
The most validated warm-up there is. Hum one steady note; we score how tightly your pitch holds.

Hold one steady tone as long as you can — maximum phonation time, a real clinical measure of breath support.

Glide low to high and back; we measure your usable range in semitones and track it over time.
Corie won't hand you a movie-trailer voice overnight or change your anatomy. What it does, honestly: helps you find the lower, steadier, more resonant end of your own range — and shows you the numbers as they improve. That's voicemaxxing that actually holds up.
Corie is your voice coach inside the app. It walks you through each drill, reacts to your voice in real time as you train, points you to the one thing to work on next, and celebrates every personal best.

Voicemaxxing is deliberately training how your speaking voice sounds — its depth, steadiness, resonance, pace and clarity — instead of leaving it to chance. Corie turns it into a measurable practice: you get a score, a top fix, and drills that move it.
You can train toward the lower, steadier end of your natural range and use resonance so your voice reads as fuller and more grounded. Corie measures your pitch in Hz so you can see it move. It won't change your anatomy or give a permanently deeper voice overnight — anyone promising that isn't being honest.
