Vocal Analyzer
What your Hz number means
The big number is your fundamental frequency: how many times per second your vocal folds vibrate right now. It is the pitch of your voice, not its volume. Speak louder and the number barely changes; slide up like you are asking a question and it climbs.
When you speak, it moves all the time — that is normal. Hold a steady “aaah” to see a stable reading, then talk normally and press Stop to get your median Hz, the one number that best describes your speaking voice.
Hertz and musical notes
Every doubling of frequency is one octave, and each octave has 12 semitones. The test names the nearest note on the standard A4 = 440 Hz tuning, plus how many cents (hundredths of a semitone) you are sharp or flat.
| Note | Frequency | Where you might hear it in speech |
|---|---|---|
| A2 | 110 Hz | The lower half of the typical male range |
| C3 | 131 Hz | Middle of the typical male range |
| E3 | 165 Hz | The gender-ambiguous zone (155–185 Hz) |
| G3 | 196 Hz | Within the typical female range |
| C4 (middle C) | 262 Hz | Above the typical female speaking range |
Why the reading jumps around
- Consonants and pauses have no pitch. The display holds the last value and the graph shows a gap.
- Creaky voice (vocal fry) at the end of sentences has an irregular, very low vibration that reads as scattered points near the bottom.
- Background sound — another voice, music, a humming fridge — can be picked up when you are quiet. Mute anything playing nearby.
- Octave slips: on a weak or breathy sound any pitch detector can briefly read double or half the real value. Single slips are filtered out; if you see many, move closer to the mic.
How does my Hz compare?
Adult men typically speak around 85–180 Hz and adult women around 165–255 Hz (Baken, 1987). The voice pitch analyzer breaks a whole reading down into those ranges and shows how much of your voice falls in each. If you sing, the vocal range test turns notes into a lowest-to-highest range instead.
Frequently asked questions
What Hz is my voice?
Press Start, talk normally for 20–30 seconds and press Stop: the median Hz shown is your typical speaking frequency. One live reading only tells you the pitch at that instant.
Is 100 Hz a deep voice?
Yes, 100 Hz is in the lower part of the typical adult male speaking range (about 85–180 Hz). It is close to G2 on a piano.
What Hz is a high voice?
For speech, a median above about 255 Hz is above the typical adult female range. Singing voices go far higher: a soprano’s top C (C6) is about 1047 Hz.
Can I change my voice Hz?
Your speaking pitch can be trained up or down within limits, and it also shifts with age, illness, hormones and fatigue. Change it gradually and without strain; a speech-language pathologist can guide lasting changes safely.
Does the test work with humming or singing?
Yes. Any voiced sound has a pitch. Humming and held vowels give the steadiest readings.
