Voice Pitch Analyzer — See What Your Voice Is Really Doing
Speak, hum or sing into your microphone and watch the note, frequency and cent deviation update as you talk. Unlike a standard instrument tuner, this page is built around continuous voice — so you can watch pitch move across a whole sentence or phrase instead of reading one held note at a time.

How to use the voice pitch analyzer
No settings to configure first — just talk and watch the numbers move.
-
Step 1
Allow microphone access
Press Start Detection and allow the browser prompt. Nothing is recorded — each frame of audio is analyzed and discarded immediately.
-
Step 2
Speak, hum or sing normally
Read a sentence aloud, hum a line, or hold a note. Stay 15–30 cm from the mic and let one voice sound at a time for the cleanest reading.
-
Step 3
Read the note, Hz and graph
The dial shows the nearest note and cent deviation; the graph underneath shows whether your pitch is steady or moving across the phrase.

Key features
Everything is visible at once — nothing hidden behind extra clicks.
Real-time voice pitch analysis
The reading updates continuously as you talk or sing, not just on a single held note.
Musical note detection
Your voice is mapped to the nearest note and octave on the standard equal-tempered scale.
Frequency in hertz
See the exact fundamental frequency of your voice, updated live as it moves.
Cent deviation
Know precisely how far above or below the nearest note your voice is sitting, in cents.
Voice stability graph
The frequency-over-time chart shows at a glance whether your pitch is holding steady or drifting.
Browser-based, no download
Runs entirely as a web page using the Web Audio API — nothing to install on desktop or mobile.
Who benefits from analyzing their voice pitch
A live pitch readout turns something you can only hear into something you can see.
Singers & vocal students
Watch whether you land squarely on a note or approach it from below or above. Sustained-line exercises show whether your pitch wanders as breath support runs low, which is easy to feel but hard to judge by ear alone.
Voice coaches & music teachers
Project the analyzer during a lesson so a student sees intonation drift as it happens, instead of relying only on your feedback after the fact. It's a quick way to make an abstract correction concrete.
Public speakers & podcasters
A flat pitch graph during a practice read is a strong sign your delivery is monotone. Watching pitch rise and fall naturally across a sentence is a simple, visual way to practise vocal variety before you record or go live.
Choir members
Check your own pitch against a written part before rehearsal, particularly on entries or exposed lines where drifting sharp or flat is most noticeable to a section around you.
Tips for more accurate voice pitch detection
Most inaccurate readings trace back to one of these.
- Get close to the mic. 15–30 cm from a built-in laptop mic gives a much stronger signal than sitting back from the screen.
- Use an open vowel. "Ah" or "oh" carries a clear fundamental; a breathy or whispered voice does not give any tracker much to lock onto.
- Reduce background sound. Fans, other voices and music in the room are the most common cause of a jumpy or wrong reading.
- Speak or sing at a natural volume. Very quiet input gets lost in the noise floor; shouting can distort the signal and read sharp.
- One voice at a time. If someone else is talking or music is playing, the analyzer may lock onto whichever source is louder.
- Give it a beat to settle. The first fraction of a second of any sound is often the least stable part of the reading — hold a tone briefly rather than reading the very first flicker.
Common use cases
A few concrete ways people actually use a live voice pitch readout.
- Checking whether you're landing on pitch during a warm-up exercise or scale
- Spotting a monotone speaking pattern before a presentation, interview or recording
- Watching pitch stability on long, sustained notes for breath-support practice
- Comparing your natural speaking pitch across morning and evening, or before and after vocal rest
- Following along in a lesson while a teacher points out where a phrase drifts flat or sharp
- Practising deliberate pitch variation for podcasting or voiceover work
- Quick ear-training drills — sing a note, then check the readout to see how close you were
Frequently asked questions
What exactly does a voice pitch analyzer show me?
It listens through your microphone and reports the pitch of your voice moment to moment: the nearest musical note, the frequency in hertz, and how many cents sharp or flat you are from that note. A graph also shows whether your pitch is holding steady or wandering.
How is this different from the main tuner or the vocal range test?
The main tuner is built for tuning instruments and sustained notes. The vocal range test is a guided two-step exercise that finds your lowest and highest note and estimates a voice type. This analyzer is for open-ended, continuous voice work — speaking, humming, sustaining a line, or checking stability over time — without a fixed script.
Can I use it to check if my speaking voice sounds monotone?
Yes. Speak a sentence naturally and watch the frequency graph. A flat, narrow line means little pitch variation, which often reads as monotone to listeners. A line that rises and falls across a few notes shows natural inflection. This is a common way presenters and podcasters spot flat delivery.
Does it work for humming and soft singing, not just full voice?
Yes, as long as the tone has a clear fundamental pitch. Humming works well because it produces a strong, steady tone. Very breathy or whispered sound has no stable pitch for any analyzer to lock onto, so results will be unreliable in that case.
How does cent deviation apply to speech, not just a sung target note?
The analyzer still rounds your pitch to the nearest note and measures the gap in cents, even in speech. For singing or ear training that number tells you how close you are to a target. In speech it is less about being "in tune" and more about seeing exactly which note your voice is centering on at any instant.
Will background noise or music mess up the reading?
Yes, more than most people expect. A pitch analyzer looks for one dominant fundamental frequency, so a second voice, music, or a fan running nearby can pull the reading off or make it jump around. A quiet room and a mic positioned close to your mouth give the cleanest result.
Can I use this with a podcast mic, headset, or lapel mic?
Yes. Any microphone your browser can access will work, including USB podcast mics, headset mics, and lapel mics through an audio interface. Select the correct input device in your browser or OS sound settings before you start, since some setups default to a built-in laptop mic.
