Voice Pitch Analyzer Online
Measure your live voice pitch, nearest musical note, tuning offset, stability, and session statistics.
Controls
Pitch Timeline
SpeakingShows recent detected pitch over time. Short gaps indicate no stable voiced pitch.
Session Statistics
How to get a cleaner reading
Use a quiet room, keep the microphone at a steady distance, and sustain a relaxed vowel for singing analysis. For speech, speak naturally for several seconds and focus on the average rather than a single instant.
Accuracy note
Microphone quality, room noise, harmonics, breathiness, vocal fry, fast pitch movement, and octave-detection errors can affect readings. Results are estimates, not medical measurements.
Privacy
Pitch analysis runs locally in your browser. The plugin does not upload microphone recordings. Stopping analysis closes the active microphone tracks.

A voice pitch analyzer online measures the fundamental frequency of your voice and converts it into useful information such as frequency in Hertz (Hz), the nearest musical note, tuning offset, pitch stability, and session statistics. Instead of judging your voice from a single moment, the analyzer tracks pitch continuously so you can see how your voice changes while you speak or sustain a sound.
Use the Voice Pitch Analyzer above when you want to examine your natural speaking pitch, practice maintaining a steadier tone, compare different vocal delivery styles, or understand the relationship between your voice frequency and musical notes.
Voice pitch is closely related to fundamental frequency, or F0—the rate of vocal-fold vibration that contributes strongly to how high or low a voice is perceived. If your main goal is simply measuring frequency rather than viewing detailed pitch movement, you can also use our Voice Frequency Test.
How to Use the Voice Pitch Analyzer
For the most useful result, use the analyzer in a reasonably quiet room and position your microphone at a comfortable speaking distance.
- Select the appropriate Analysis Mode for what you are testing.
- Leave the A4 Reference at 440 Hz unless you intentionally need another musical tuning reference.
- Adjust the Noise Gate only if background noise is being mistaken for your voice.
- Press Start Analysis and allow microphone access when your browser asks.
- Speak naturally or sustain a comfortable sound while the analyzer tracks your pitch.
- Watch the live frequency, nearest note, pitch timeline, stability, and confidence indicators.
- Continue for several seconds to build more meaningful session statistics.
- Use Copy Results if you want to save the summary, or Reset Session before starting another test.
Modern browsers require your permission before a website can access microphone input through getUserMedia().
If you are specifically trying to determine how deep your voice sounds rather than examining detailed pitch behavior, try the main Deep Voice Test.
Understanding Your Voice Pitch Results
The analyzer gives you several measurements because vocal pitch naturally moves from moment to moment. A single Hz number does not describe an entire speaking voice.
Current Pitch
Current Pitch shows the estimated fundamental frequency being detected at that moment.
Frequency is measured in Hertz. For example, a reading of 220 Hz means the detected periodic vocal signal repeats approximately 220 times per second. Higher fundamental frequencies generally correspond to higher perceived pitches, while lower frequencies generally correspond to lower perceived pitches.
If you want more context about the frequency spectrum of human voices, see our Human Voice Frequency Range guide.
Nearest Musical Note
The Nearest Note converts the detected frequency into its closest note in the musical tuning system selected by the A4 reference.
The default setting is A4 = 440 Hz, the widely used reference pitch associated with the musical note A above middle C.
A voice does not remain on one musical note during normal speech. Your displayed note may therefore change rapidly as you talk.
Cents and Tuning Position
The tuning indicator shows whether the detected pitch is below or above the nearest musical note.
A result near the center indicates that your frequency is close to that note. A positive cent value means the pitch is above the reference note, while a negative value means it is below it.
This measurement is particularly useful when sustaining vowels, practicing singing, or checking how steadily you can hold a pitch.
Stability
The Stability reading helps you understand how consistently the analyzer is detecting your pitch.
Natural speech is intentionally variable, so a changing pitch during conversation is not necessarily a problem. Stability becomes more useful when you intentionally sustain a vowel or note and want to observe how much your pitch moves.
Confidence
The Confidence indicator reflects how reliably the current audio signal can be interpreted as a pitched sound.
Background noise, breath sounds, consonants, microphone distortion, extremely quiet input, and rapidly changing speech can all make pitch detection less reliable. Because estimating fundamental frequency from real-world voice recordings is technically challenging, individual readings should be interpreted as measurements rather than perfect representations of perceived voice quality.
Pitch Timeline and Session Statistics
The pitch timeline is one of the most useful parts of this analyzer because it shows your voice across time instead of reducing the session to one number.
As you speak, the graph records recent detected pitches. Short gaps can appear when the analyzer cannot identify a stable voiced signal—for example during silence or unvoiced consonants.
After enough voiced audio has been detected, the Session Statistics panel can summarize measurements such as:
- Average pitch — the average detected frequency during the analyzed session.
- Minimum pitch — the lowest reliable frequency detected.
- Maximum pitch — the highest reliable frequency detected.
- Pitch span — the distance between lower and higher detected pitches.
- Most common note — the musical note detected most frequently.
- Voiced time — the amount of analyzed audio containing usable pitched voice.
For a simpler overview of where your voice falls across notes, try our Voice Range Test. If your goal is broader vocal classification, the Voice Type Test provides a different type of analysis.
Speaking Pitch vs Vocal Range
Your habitual speaking pitch and your total vocal range are not the same measurement.
Speaking pitch describes the frequencies you commonly use during speech. Vocal range describes the broader span of notes you can intentionally produce from low to high.
Someone may therefore have a relatively low conversational pitch while still being capable of producing much higher notes.
If you are investigating the lower end of your range, our guides to Bass Vocal Range and Baritone Vocal Range explain these classifications in more detail.
What Can You Use a Voice Pitch Analyzer For?
A pitch analyzer can be useful for several kinds of voice practice.
You can compare your relaxed speaking voice with a more projected voice, observe how pitch changes when reading versus speaking spontaneously, practice holding sustained vowels, monitor pitch movement during voice acting exercises, or explore how resonance and pitch interact.
However, pitch is only one characteristic of a voice. Resonance, articulation, intensity, breath support, formants, speaking habits, and vocal tract configuration also affect how a voice sounds.
That distinction matters if your goal is developing a fuller or deeper sound. Lowering the displayed Hz number alone does not automatically create a healthier or better-sounding voice. Our Voice Resonance Exercises guide explores another important part of perceived vocal depth, while How to Speak With a Deeper Voice focuses on practical speaking technique.
How to Get a More Accurate Reading
Microphone-based pitch detection works best when the incoming signal contains a clear, periodic voice component.
For better results:
- Test in a quiet environment.
- Keep a consistent distance from the microphone.
- Avoid whispering during pitch measurement.
- Speak at a comfortable volume rather than forcing your voice.
- Give the analyzer several seconds of voiced speech.
- Test sustained vowels when you want to examine pitch stability.
- Increase the noise gate if environmental sounds repeatedly trigger detection.
- Compare several sessions instead of treating one instant reading as definitive.
Pitch estimates can vary with microphone quality, room noise, browser audio processing, vocal technique, and the detection algorithm. Browser-based tools are useful for personal analysis and practice, but they are not substitutes for clinical voice assessment.

Privacy and Microphone Access
The analyzer requires microphone permission because it needs a live audio stream to calculate your pitch. Browsers are designed to request explicit permission before providing a webpage with microphone access.
The tool interface is designed for browser-based analysis. You can stop analysis when you are finished and revoke microphone access through your browser settings whenever you choose.

Voice Pitch Analyzer FAQ
What is voice pitch measured in?
Voice pitch analysis commonly uses fundamental frequency measured in Hertz (Hz). Fundamental frequency represents the repeating rate of vocal-fold vibration associated with perceived pitch.
Does a lower Hz number always mean a deeper voice?
A lower fundamental frequency generally contributes to a lower perceived pitch, but perceived voice depth also depends on resonance and other acoustic characteristics. Pitch should therefore be treated as one component of voice quality rather than the entire definition of a “deep voice.”
Why does my pitch change while I speak?
Normal speech contains continuous pitch movement. Intonation changes with words, emphasis, emotion, sentence structure, and speaking style, so your live reading should not remain fixed at one frequency.
Why does the analyzer sometimes stop detecting my voice?
Pitch detection requires a sufficiently clear periodic signal. Silence, breath sounds, unvoiced consonants, low volume, background noise, or microphone interference can temporarily prevent a stable pitch estimate.
What does the A4 440 Hz setting mean?
It determines the reference used when converting frequencies into musical note names. With the default setting, the musical note A4 corresponds to 440 Hz.
Should I test one sound or normal speech?
Use both depending on your goal. Normal speech gives a more realistic picture of conversational pitch variation, while a sustained vowel makes it easier to examine stability and tuning.
Can this tool determine whether I have a bass, baritone, tenor, alto, or other voice type?
Pitch data can provide useful clues, but formal singing voice classification involves more than one measured frequency. Range, tessitura, timbre, registration, and comfortable singing area also matter. For classification, use the dedicated Voice Type Test rather than relying only on one pitch reading.
Is an online voice pitch analyzer a medical diagnostic tool?
No. It is designed for educational, practice, and informational voice analysis. Persistent pain, sudden voice changes, or other vocal-health concerns should be evaluated by an appropriately qualified healthcare professional.
