Voice Pitch Explorer
Explore pitch during voice practice without inferring gender. This page measures neither resonance nor formants.
Your pitch position and overlap context will appear here.
100% client-side. Audio is never uploaded. Results are stored only when you choose Save.

Ten seconds provides more context than one held note.
Read the overlap note
Pitch is one cue among resonance, formants, articulation and style.
Why this analyzer avoids binary gender detection
Voice pitch distributions overlap. A single threshold would misrepresent many cisgender, transgender and non-binary speakers, and gender identity is not an acoustic property that software can determine.
Pitch alone does not measure resonance, gender identity, anatomy or how others perceive a voice.
Method and interpretation
Use this result
Explore pitch during voice practice without inferring gender. This page measures neither resonance nor formants.
A changed median shows changed pitch in this recording. It does not prove a change in perceived gender.
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
Can a voice test determine gender?+
No. Gender identity cannot be determined from audio. This tool only places speaking pitch on a continuous lower-to-higher presentation scale.
Why not label voices male or female?+
Pitch ranges overlap substantially, and resonance, style, language and identity cannot be reduced to one binary result.
What data is used?+
Pitch alone does not measure resonance, gender identity, anatomy or how others perceive a voice.
Is audio uploaded?+
No. Microphone samples are processed locally and discarded after the result.
