Voice Gender Analyzer
A supportive feedback tool for voice training. Speak naturally and see two acoustic cues that shape how a voice is perceived — your average pitch (F0) and your resonance (formants) — placed on a masculine↔feminine perceptual spectrum.
ℹ This measures acoustics only. Pitch and resonance are sounds a microphone can measure; gender identity and biological sex are not, and this tool does not and cannot determine them. The result is where your voice’s sound currently sits on a perceptual range built from population averages — many voices fall in the overlap zone, and that is completely normal. It’s designed as encouraging feedback for voice training, including gender-affirming voice work, characterisation, or curiosity. Estimates depend on your mic, room, and how you’re speaking. Your mic is analyzed live and never recorded or uploaded.

How It Works
While you speak, the tool tracks two things many listeners use to perceive a voice as more masculine or feminine. The first is fundamental frequency (F0) — your average pitch — found with a YIN pitch detector and reported as the median over your voiced samples (median resists the odd glitch). The second is resonance: the tool runs LPC analysis to estimate your vocal-tract formants and reports the average of the first three. Shorter or more “raised” vocal tracts tend to produce higher formants (a brighter resonance), which listeners associate with feminine-perceived voices; lower formants read as darker, more masculine-perceived. The marker blends both cues (pitch weighted a little more) and shows roughly where your voice’s sound currently sits.
For context, adult speaking pitch averages sit around 100–130 Hz for many men and 190–220 Hz for many women, with a large overlap in between — and plenty of people sit happily in that overlap. Those are population statistics, not targets, and they say nothing about who you are. If you’re training your voice, the most useful thing here is watching the numbers change as you experiment: lift your larynx, brighten your vowels, find a comfortable pitch, and see the marker move. Trust your ears and, for gender-affirming work, a qualified speech-language pathologist over any single number.
