Vocal Pitch Monitor Online
Sing into your mic and watch your pitch draw a live line across a note grid — a free voice pitch analyzer for held notes, slides, and vibrato. Nothing is recorded.
Your browser will ask for microphone access — your voice is analyzed on your device and never uploaded.
How to Monitor Your Vocal Pitch
No file, no account — sing and watch the line.
Allow the Microphone
Press Start monitoring and allow mic access when the browser asks. Everything runs on your device.
Sing or Speak
Hold a note, sing a scale, slide a siren, or just read a sentence — your pitch starts drawing immediately.
Read the Trace
Flat line on a grid row = a steady note. Waves = vibrato. A rising ramp = a smooth slide. The last ten seconds are always on screen.
A Voice Pitch Analyzer You Can Practice With
Not a snapshot — a picture of the last ten seconds of your voice.
See Your Pitch as a Line
Your voice draws a live trace across a semitone grid — scoops into notes, drift on long tones, and vibrato all become visible instead of just audible.
Watch Steadiness, Not Snapshots
A single readout tells you where you are; the trace tells you where you've been for the last ten seconds — exactly what you need to judge a held note.
Note, Hz, and History
The current note and frequency sit above the graph, and every note you hold for a moment lands in a trail below it, so nothing you sang gets lost.
Your Voice Isn't Recorded
The mic signal is analyzed on your device frame by frame and discarded. Nothing is stored or uploaded — practice without an audience.
Made for Voices
Tuned for the singing and speaking range — sirens, scales, held vowels, and pitch-matching drills all trace cleanly.
Works on Mobile
Runs in the browser on iOS, Android, Chrome, Firefox, Safari, and Edge — practice anywhere with your phone's mic.
Practice Without an Audience
Your voice is analyzed on your own device, frame by frame, and discarded. No audio is recorded, stored, or uploaded — the trace on screen is the only place your singing exists, and it scrolls away in ten seconds.

What Singers Watch For
The trace turns pitch problems you can hear into shapes you can fix.
Held-Note Practice
Sing a long tone and watch the line — flat drift shows up before you hear it
Pitch Matching
Play a reference note, then sing and land your line on the same grid row
Vibrato Control
See your vibrato's width and speed as a wave in the trace
Scales & Sirens
Slide bottom to top and check the shape — smooth ramp or staircase
Speaking Pitch
Read a sentence and see where your speaking voice actually sits

Hear It Once, See It for Ten Seconds
The frustrating thing about pitch practice is that sound vanishes. You hold a note, something felt slightly off, and by the time you wonder what happened, it’s gone. A vocal pitch monitor fixes that by turning your voice into a line: the pitch of the last ten seconds stays on screen, drawn over a grid of notes, so you can sing first and study after.
Reading the line like a voice teacher
Each horizontal line of the grid is a semitone — one piano key, with the Cs labeled so you know your octave. A steady held note is a flat trace sitting on its row. A note that starts under and slides up is a scoop — the most common habit singers can’t hear in themselves. Slow sagging on long tones shows as a gentle downward drift, and vibrato appears as a regular wave whose width and speed you can actually see. These are exactly the things a teacher points out; the monitor lets you spot them yourself, mid-practice.
For speaking voices too
A voice pitch analyzer isn’t only for singers. Read a sentence aloud and the trace shows where your speaking voice sits and how much it moves — useful for presentation practice, accent and intonation work, and any kind of voice training where you’re trying to shift or steady your habitual pitch. The note history under the graph doubles as a record of the range you covered.
Private enough to actually practice
Nobody sings scales freely into a tool they think is recording them. This one isn’t: the microphone signal is analyzed on your device frame by frame and thrown away. Nothing is stored or uploaded, there’s no account, and the only trace of your practice is the one on screen — which scrolls away as you go.
The rest of the pitch toolkit
For a tuner-style snapshot — one note, exact Hz, a cents needle — use the pitch detector; to just name a note, the note identifier shows it on a piano key. When you’re ready to record properly, the voice recorder captures your take, and online autotune tunes a recorded vocal to the key you were aiming for.

Vocal Pitch Monitor FAQ
What does the vocal pitch monitor show?
A live graph of your voice's pitch over the last ten seconds, drawn across a semitone grid with note names on the lines. Above it you see the current note and exact frequency; below it, a trail of the notes you held. The line makes things you can't easily hear — slow drift, scoops into notes, vibrato width — visible at a glance.
How is this different from the pitch detector?
Same detection engine, different view. The pitch detector gives you a tuner-style snapshot — one note, one frequency, a cents needle. The monitor draws your pitch over time, which is what you want for practicing held notes, slides, and vibrato rather than checking a single pitch.
Is my voice recorded or uploaded?
No. The microphone signal is analyzed on your own device and discarded frame by frame — nothing is recorded, stored, or sent anywhere, and the mic switches off the moment you press Stop.
Can I use it for my speaking voice?
Yes. Read a sentence aloud and the trace shows the range your speaking voice moves in and where it settles. It works for any voice work — public speaking practice, accent work, or voice training — not just singing.
Why does the line break sometimes?
The line only draws while there's one clear pitch to track. Breaths, consonants, whispers, and background noise have no single pitch, so the trace pauses and resumes — that's normal, and the gaps themselves show you where your phrases breathe.
What do the grid lines mean?
Each horizontal line is one semitone — one piano key. The darker lines are C notes, labeled with their octave (C4 is middle C), so you always know which part of your range you're in. Holding a note steady means keeping the trace flat on one line.
Is it free?
Completely free — no account, no upload, no limits. It runs entirely in your browser and only asks for microphone permission, which you can revoke at any time.
