How to use the voice pitch analyzer
Press Start, allow the mic and hold an “ah” for 3 seconds, then read a sentence aloud. The line shows your pitch; the panel shows your average and range.
- Press Start and choose Allow. The analyzer listens live; nothing is recorded.
- Hold a vowel for a few seconds to see one steady line and its note.
- Read a short passage at your normal volume to see how your pitch moves while you speak.
- Set a target band if you’re practicing a range, and watch the share of time inside it.
- Press Stop to release the microphone, then Copy summary to keep your numbers.
It works as a vocal pitch monitor online on phones and computers, with no install. With the tool focused, S starts and stops, F freezes the graph, B shows or hides the band and R resets the statistics.
How the pitch detector works
Your voice’s pitch, or fundamental frequency (F0), is how many times per second your vocal folds vibrate. The pitch detector looks for that repeating pattern in 85 ms slices of sound, 25 times a second, using the McLeod Pitch Method. It only counts slices with a clear, voiced sound, so pauses, breaths and most consonants become gaps in the line.
Each value is smoothed over the last five readings, and an octave guard ignores sudden jumps to double or half the pitch unless they last, a common error with any pitch finder. Voice processing on the microphone (echo cancellation, noise suppression, automatic gain) is switched off where the browser allows, because it can bend readings.
It works best with one voice in a quiet room. Background music, several people talking and whispers (which have no pitch) make readings unreliable.
Reading your results: Hz, notes, average and range
| Readout | What it means |
|---|---|
| 182 Hz | Vocal fold vibrations per second right now |
| F♯3 −28¢ | The nearest note and how far from it, in hundredths of a semitone |
| Average | The middle of your pitch on a musical (semitone) scale, so high notes don’t outweigh low ones |
| Median | The middle value: half of your voiced time was higher, half lower |
| Range | From the 5th to the 95th percentile, so stray readings don’t stretch it; the span in semitones shows how much your voice moves |
| Lowest · highest | The extremes of the session |
Speaking pitch varies a lot between people, and for one person with mood, language, tiredness and context. The analyzer shows numbers, not judgments. A wide range usually sounds lively; a narrow one can sound flat, which is what people mean by monotone.
Practicing with a target band
Turn on Target band and enter a low and a high value in Hz or as notes, such as 165 and 200, or G3 and B3. The band is shaded on the graph, and the statistics show how much of your voiced time fell inside, below and above it. “Use my last 30 s” sets the band to the middle 80% of what you just said.
Short, regular sessions work better than long ones. If your voice feels tired or strained, stop and rest. For presentations or speaking exams such as PTE, watching the line rise and fall across a sentence helps you practice intonation; the tool says nothing about scores.
Analyze a recording
Switch to the File tab to analyze an MP3, WAV or M4A file up to 5 minutes long. You get the pitch track for the whole file, the same statistics and playback. One voice at a time works best. To make a recording first, use the online voice recorder.
Singing: find the note you’re singing
Sing a steady vowel and read the note and cents: 0¢ is right on the note, +50¢ is halfway to the next note up. The line shows whether you hold the pitch or drift. To practice matching a note, play it with the tone generator, then sing it back. For instruments, the online tuner shows the string you’re playing. To see the overtones in your voice as well, try the spectrogram.
