Am I Monotone?
Talk for 12 seconds and get a variation score with a plain-language band. “Monotone” here means little pitch movement while you speak — not whether you can sing. Everything is measured in your browser, and nothing is uploaded.

We track your pitch
Your browser follows your fundamental frequency (F0) frame by frame while you speak, and measures how far it moves around its own average.
See where you land
You get one score from 0 to 100 and the band it falls in, from very steady to highly varied, with what that tends to sound like.
What the score means
The score is how much your pitch spread around its own average, as a share of that average — so a deep voice and a high voice are measured on the same scale. The two ends are set from recordings of someone deliberately speaking flat and deliberately speaking with energy, so 0 and 100 are things a real voice actually does.
| Band | Score | What it sounds like |
|---|---|---|
| Very steady | 0–19 | Your pitch stayed close to one level while you spoke. This is the range people usually mean by a monotone voice, and it is also the most common way to sound when you are recording yourself: even, controlled, deliberate. |
| Steady | 20–39 | Your pitch moved a little. An even, controlled delivery that stays close to one level. |
| Balanced | 40–59 | Your pitch moved a moderate amount — the middle of ordinary conversation. |
| Varied | 60–79 | Your pitch moved a lot while you spoke. An animated, strongly inflected delivery. |
| Highly varied | 80–100 | Your pitch moved across a wide range while you spoke. A very animated, highly inflected delivery. |
Both ends were measured on recordings made through this page, not carried over from somewhere else. The Deepr app reads the same ratio when it scores breath control, but on its own scale. And this describes how you sounded in twelve seconds, not how you always sound.
FAQ
Pitch variation, explained
What is a monotone voice?
A monotone voice is one whose pitch stays close to a single level while speaking. It is about movement, not depth: a deep voice and a high voice can both be monotone. This test measures the movement itself, so it answers the question with a number rather than an impression.
How does this score work?
Your browser tracks your fundamental frequency (F0) while you speak, then measures how much it spreads around its own average, as a share of that average — so a deep voice and a high voice are measured on the same scale. The ends of the scale are measured, not assumed: someone deliberately speaking monotone into a phone lands near the bottom, someone deliberately animated near the top, and this page maps between them onto 0 to 100. Frames where the pitch detector slipped by an octave are dropped first: they are recognised by breaking the line your pitch was tracing, which real speech does not do. The Deepr app computes the same ratio when it scores breath control, though on a scale of its own — it measures the pitch differently, so the two numbers are not interchangeable.
Is a steady voice bad?
No. A steady voice reads as calm and authoritative, and plenty of well-known speaking voices sit at the steady end. A varied voice reads as warm and animated. Neither end of this scale is a defect, and the score is a description of how you sounded in one short take, not a verdict on your voice.
Can I change how much my pitch moves?
Some of it is habit rather than anatomy. Pitch movement tracks energy, pace and how engaged you are with what you are saying, so the same person scores differently reading a list and telling a story. Recording yourself in both and comparing the two numbers is the honest way to see your own range.
How long do I need to talk, and what should I say?
Twelve seconds, with at least three seconds of actual speech. Say something you would say out loud anyway — what you did this morning, what you have planned this weekend. Reading a passage aloud tends to flatten pitch movement, so it measures your reading voice rather than your speaking voice.
Is my voice recorded or uploaded?
No. The analysis runs entirely in your browser through the Web Audio API. Your voice is processed on your device as you speak and is never recorded, stored, or sent to any server.
Is this a singing test?
No. It measures the pitch movement of your speaking voice over a few seconds. It says nothing about your singing range, and it is not a clinical or diagnostic assessment.
Measured your variation. Now measure your depth.
Deepr gives you a daily voice score built on what it measures — how deep you sound, how steady your pitch is, how consistent your volume is — with exercises for the depth side of that.
