Voice Hz Test Online
Get a repeatable median speaking pitch in Hz; keep the passage and microphone position consistent.
Your speaking frequency and detailed statistics will appear here.

Speak naturally
Talk continuously for ten seconds at your normal conversational pitch.
Read your statistics
Compare the median, mean, detected range and pitch stability rather than relying on one instant.
What your voice frequency result means
Voice frequency is measured in Hertz. A result of 110 Hz means the vocal folds completed approximately 110 vibration cycles each second during the analyzed speech.
Pitch is only one part of how a voice sounds. Resonance, formants, articulation, loudness and microphone characteristics all affect perceived depth. Treat the result as a repeatable measurement, not a judgment of voice quality.
Method and interpretation
Use this result
Get a repeatable median speaking pitch in Hz; keep the passage and microphone position consistent.
110 Hz and 118 Hz on different passages can reflect speech melody; repeat the same passage before comparing.
Read the measurement guideWhat is calculated?
Autocorrelation analyzes 2,048-sample frames about every 45 ms, within 60–400 Hz. Frames need RMS ≥ 0.01 and correlation ≥ 0.55. A result requires 20 detected frames and at least 20% detection coverage.
Median, mean and standard deviation use detected frames. Endpoints are the 2nd and 98th percentiles; trimming extremes does not guarantee removal of octave errors.
Microphones, noise and octave errors affect results. Accuracy has not been independently validated. Pitch bands are interface descriptions, not population norms or diagnoses.
These tools share one pitch detector; each page offers a different way to interpret its measurements.
Frequently asked questions
What is a voice Hz test?+
A voice Hz test estimates the fundamental frequency of your speaking voice. It reports how many vocal-fold vibration cycles occur per second.
What is a normal speaking voice frequency?+
Adult speaking voices vary widely. Many adult male voices average roughly 85–155 Hz and many adult female voices roughly 165–255 Hz, with substantial overlap.
Why does my result change between tests?+
Pitch changes with sentence choice, emotion, hydration, posture, time of day and microphone position. Use the median of several relaxed tests.
Is this the same as vocal range?+
No. Speaking frequency measures your conversational pitch. Vocal range measures the lowest and highest musical notes you can produce.
Is my recording uploaded?+
No. Audio is analyzed inside your browser and discarded when the test ends.
