Pitch dynamics
Melody is measured, not felt.
We track your fundamental frequency 100 times a second and score variability, range and dynamism. Under ~1.5 semitones of variation reads as monotone; engaging speakers typically sit above 2.5.
Free voice reading · no signup · twenty seconds
Your voice is deciding rooms you never knew you lost.
Record twenty seconds. Resonate measures how you actually land — authority, warmth, presence — from real acoustics, not vibes.

How it works
What we actually measure
Not vibes, and not a language model guessing from a transcript. Resonate runs signal analysis on the audio itself and scores it against listener-perception research.
Presence band · 2–4 kHz
Authority has an address.
The 2–4 kHz ‘speaker's formant’ is the slice of the spectrum that cuts through rooms and microphones. We measure exactly how much of your energy lives there.
Spectral tilt · alpha ratio
Brightness versus warmth, in decibels.
The balance of 1–5 kHz to 50–1000 Hz energy. Tilt too dark and words blur into the chest; too bright and the tone turns thin. It's one number, and yours has a value.
Voice quality · HNR
How clean is the tone under the words?
Harmonics-to-noise ratio separates clear tone from breath and rasp, alongside jitter, shimmer and vocal fry. Higher reads as more resonant — and it responds to training.
The depth
Six dimensions. 19 measurements.
The free reading shows you the shape of all of it. The plan shows the numbers — and the drill that moves each one.
Melody
How much your voice moves
- Pitch variability
- Pitch range
- Pitch dynamism (PDQ)
Cut-through
Whether your words actually reach people
- Presence band (2-4 kHz)
- Spectral tilt (alpha ratio)
- Voice clarity (HNR)
Pace & silence
Speed, rhythm, and the confidence to pause
- Speaking rate
- Articulation rate
- Syllable rate
- Pause ratio
- Average pause length
- Phrase length
Control
Breath support and steadiness
- Pitch steadiness (jitter)
- Volume steadiness (shimmer)
- Vocal fry (creak)
Warmth
The richness people relax into
- Chest band (0-500 Hz)
- Average pitch
Words
Fillers, clarity of diction
- Filler words
- Intelligibility (ASR)
Percentiles come from research bands, not invention — “typical speakers sit at 3–6 st of pitch variability; you’re at 1.9” is the kind of sentence you’ll get.
The rule
We never flatter.
Voice apps that tell everyone they’re improving get gamed — and get ignored. Resonate scores what the microphone heard, against published listener-perception research. An honest 5.4 with a clear path up is worth more than a flattering 8.2 you can’t trust.
When a score is low, you’ll see why in the acoustics — and which drill moves it. When we can’t measure enough, we say so instead of inventing a number.
What you get
“Your voice is steadier than the research band demands. Your warmth is not— the chest band is running thin. Here’s the resonance drill.”
What you’ll never get
“Great job! Your voice is incredible!”
Pricing
One plan. Built for months, not moments.
Voices change over weeks of training, and the proof is in the trend line. That’s why the annual plan is the one we’d pick.
