Find out how high or low you speak. Record yourself reading aloud, or drop in a speech recording, and the analyzer measures the fundamental frequency of your voice every 10 ms: average pitch in Hz, range, variation and a pitch-over-time graph you can play back. Everything runs on your device.

How to use the Voice Pitch Analyzer
Record or upload: press Record my voice and read a paragraph aloud for 20–60 seconds, then press Stop and analyse. Or drop an audio file. A demo voice is analysed when the page opens.
Read the results: the tiles show your average and median pitch, range, variation and how much of the recording was voiced.
Check the graph: each dot is one 10 ms pitch measurement; the orange line is the smoothed melody of your speech. Press play or click the graph to hear any moment.
Set a target range if you are training your voice, and watch the percentage of speech that lands inside it.
Fine-tune the pitch floor, ceiling and voicing sensitivity under Analysis settings if a very deep or very high voice is misread.
Download the graph or the CSV to track your progress over time.
Pitch, Hz and notes
Speaking pitch is the fundamental frequency (F0) of the voice. Pitch is perceived on a ratio scale, so the tool reports variation in semitones: the distance between two pitches is 12 × log2(f2 ÷ f1) semitones, and doubling the frequency is one octave (12 semitones). The nearest note is found with n = 69 + 12 × log2(f ÷ 440), where 69 is A4 = 440 Hz.

Reading your pitch graph
Green dots are individual 10 ms measurements. Gaps are pauses and unvoiced sounds such as s, f, t and breaths.
The orange line is a 0.5-second smoothed contour: the melody of your speech. Statements usually drift down towards the end (declination); yes/no questions often rise.
The dashed line is your average. The shaded band is your target range, if you set one.
The grey strip at the bottom shows loudness, which helps you match pitch changes to stressed words.
Tips for an accurate measurement
Record 30–60 seconds of natural reading or talking, not single words: short clips exaggerate the effect of one excited phrase.
Use a quiet room, keep the microphone 15–30 cm from your mouth and avoid music or other voices in the background.
For progress tracking, use the same text, microphone and time of day each session.
Speaking louder usually raises pitch; compare recordings made at a similar volume.
This is an analysis aid, not a medical device. Sudden or lasting changes in your voice are worth discussing with a doctor or speech-language pathologist.
Frequently asked questions
How is voice pitch measured?
The tool measures the fundamental frequency (F0) of your voice, the rate at which your vocal folds vibrate, in hertz. The audio is resampled to 8 kHz and split into overlapping frames every 10 ms. Each frame is analysed with the YIN pitch algorithm, which finds the repeating period of the waveform; F0 = sample rate ÷ period. Frames that are too quiet or not periodic enough (breaths, s and f sounds, pauses) are marked unvoiced and ignored.
What is a normal speaking pitch?
Commonly cited average speaking pitches are roughly 85–155 Hz for adult men and 165–255 Hz for adult women, with children higher still, often above 250 Hz. These are broad averages, not rules: healthy voices fall outside them, and your own pitch changes with mood, volume, tiredness and the kind of speech.
What do the pitch range and variation numbers mean?
Pitch range is the span between the 5th and 95th percentile of your voiced pitch, so a few stray points don't exaggerate it; it is shown in Hz and in semitones (12 semitones = one octave). Variation is the standard deviation of your pitch in semitones around your average. A low value means a steady, flatter delivery; a higher value means more melody and emphasis. The labels narrow, moderate and wide are this tool's rough guide at 2 and 4 semitones.
Why is the average different from the median?
The average (mean in Hz) is pulled up by high excited moments or rising questions, while the median is the middle value of all voiced frames. If the two are close, your pitch is evenly spread; if the average is clearly higher, you have occasional high peaks. Many voice coaches track the median because it is less affected by outliers.
How can I use it for voice training?
Record the same passage regularly under similar conditions, set a target range, and compare the percentage of speech inside it and your median pitch over time. Download the CSV or PNG to keep a log. Pitch is only one part of how a voice is perceived; resonance, intonation patterns and speech rhythm matter too, so consider working with a qualified voice coach or speech-language pathologist.
Why are some points wrong or missing?
Background noise, music, reverb and very breathy or creaky voice can confuse pitch detection. The analyzer corrects most octave jumps, but if your voice is very deep, lower the pitch floor to 50 Hz; for a child or singing, raise the ceiling. Lower the voicing sensitivity if noise appears as scattered points, raise it if quiet speech is missing.
Is my recording uploaded?
No. Recording, decoding and pitch analysis all happen in your browser with the Web Audio API. Nothing is sent to a server, and the recording disappears when you close the page unless you download it.
Are all the tools on FreeToolCabin tested for quality and accuracy?
Yes! Every tool on our site undergoes automated Q/A testing in real browser environments to ensure high precision, correct output, and zero errors. If you happen to spot a bug or have a suggestion, please contact us at [email protected] and our team will review it right away.
