Rate My Voice

Record a short take and rate your voice in seconds: an honest 0–100 score for intonation, steadiness, vibrato, range and consistency, plus a tone-color readout of your warmth and brightness.

Tap the microphone and sing for 10–30 seconds: a scale, a melody, or one held note.

Why Rate Your Singing Voice?

Most singers have no objective feedback loop. You hear yourself from the inside, through bone and bias, and the people around you are too polite to say you're 30 cents sharp. A voice rating replaces feelings with measurements — the same five numbers a vocal coach would judge by ear.

🎯 Find the real problem

"I sound off" is not actionable. "My high notes land 35 cents sharp and my long notes drift flat" is a Tuesday practice plan. The score breakdown tells you which of the five skills to attack first.

📈 Track progress honestly

Rate the same phrase every week. When steadiness climbs from ±40¢ to ±15¢, that's not vibes — that's measurable improvement you can trust on the days it doesn't feel like it.

🎤 Audition and warm-up check

A two-minute take before a performance tells you if today is a sharp day, a wobble day, or a settled one — before the audience tells you instead.

How the Voice Rater Works

What Gets Measured

  1. In-tune — how close each held note lands to the nearest piano pitch, in cents (100¢ = half a semitone).
  2. Steadiness — irregular pitch wobble while you hold a note, with regular vibrato separated out — a healthy spin is not counted against you.
  3. Vibrato — oscillation rate in Hz and width in cents; a healthy 5–6 Hz spin scores best.
  4. Range — the semitone span you actually sang, from lowest to highest detected note.
  5. Consistency — how much of the take had clear, detectable pitch versus breaks and breath.
  6. Tone color — warmth (share of loudness below 1 kHz) and brightness (absolute spectral centroid), reported as descriptive positions rather than judged scores.

How to Get Rated

  1. Record 10–30 seconds of singing — a scale, a chorus, or held notes.
  2. Stop and the score appears instantly: overall rating, five dimension bars, a tone-color readout, and a pitch timeline chart.
  3. Re-record freely — nothing is uploaded or stored, so you can rate the same phrase as often as you like.

Features

📊 Five measured dimensions

Intonation in cents, steadiness, vibrato rate and width, range in semitones, consistency — every score shows the raw measurement behind it.

🎚️ Live pitch readout

While you sing, the current note and its cent offset update in real time — the same detector that powers our guitar tuner and vocal range test.

📈 Pitch timeline chart

Every note plotted against semitone gridlines: scooped attacks, drifting sustains and shaky transitions become visible.

🔒 Local-first privacy

The rating never uploads anything — audio is analyzed in your browser as you sing. There is no upload feature at all, and nothing is stored once you close the page.

🎨 Tone color descriptors

Warmth and brightness measured from the spectrum of your voice — brightness from the spectral centroid, warmth from energy below 1 kHz — framed as description, not judgment, and comparable across voice types.

🔁 Unlimited takes

Record, adjust, re-record. Progress shows up in the steadiness and intonation bars long before you can hear it yourself.

What Singers Say About the Voice Rater

★★★★★

"The cents-off readout is brutally honest in the best way. I thought I was landing my notes — turns out I was 30 cents sharp on every high one. Two weeks of fixing that and my choir director noticed."

Priya M.

Choir Alto, Community Ensemble

★★★★★

"Recording myself always felt useless because I had no idea what to listen for. The vibrato measurement plus the tone-color readout gave me two concrete things to work on instead of vague vibes."

Dan O.

Bedroom Songwriter

★★★★☆

"I use it before every audition as a two-minute warm-up check. The pitch graph alone is worth it — you can see exactly where a run falls apart."

Theater Auditioner

Frequently Asked Questions

How does the voice score work?

Your recording is pitch-tracked note by note in your browser. Intonation measures how close each held note lands to the nearest piano pitch in cents; steadiness measures irregular wobble with regular vibrato fitted and subtracted first, so a healthy spin is never counted against you; vibrato detects rate in Hz and width in cents; range is the semitone span you actually sang; consistency is how much of the take had clear pitch. The overall score weights these 30/25/15/10/20.

Does singing higher automatically make my voice brighter?

No — pitch and brightness are two different things. They often move together, which is why they are easy to confuse, but they can be controlled independently: a covered operatic high note can sound dark and round, and a resonant low note can sound bright. The brightness reading is pitch-adjusted (the acoustic side effect of note height on the spectral centroid is removed), so the key you sing in does not tilt it — what moves it is how you produce the sound.

What does my warmth label mean — for example "Lean low end"?

Warmth describes how much of your voice’s loudness sits below 1 kHz. "Lean low end" means the low end is restrained rather than thick — the opposite of boomy or muddy — which usually comes with a clean, clear-contoured sound, just with less chesty weight and low-frequency cushion than "Warm coloring" or "Deep, chesty warmth". None of the warmth labels are good or bad, and none are a skill score: a lean low end does not mean you are not a low voice, that your low notes are weak, or that anything is wrong with your voice.

Why does my tone color change between recordings?

Recording conditions move these readings a lot: the microphone and its distance, room reflections, phone noise suppression, backing tracks and EQ all change how much low-frequency energy reaches the analyzer. Read tone color as a tendency of that particular recording, not a fixed classification of your voice — to track it over time, record in the same room with the same setup.

Is my voice uploaded anywhere?

No, never. Pitch, vibrato and tone color are all computed locally in your browser as you sing — there is no upload feature at all, and nothing is stored once you close the page.

What should I sing for the best rating?

Anything that moves through several notes and holds a few of them: a major scale, the chorus of a song you know well, or a five-note siren. Avoid heavy backing music — the analyzer listens for your voice alone.

Can I rate my speaking voice?

You can, but the dimensions are tuned for singing — a monotone reading will score oddly on range and vibrato. For speaking pitch, the pitch detector is a better fit.
