About the tool
What is a Voice Gender Analyzer?
A voice gender analyzer examines acoustic characteristics that can influence how a recording may be perceived. This free online tool uses your device's microphone to analyse fundamental frequency, pitch movement, recording quality, and a local spectral-balance proxy directly in the browser.
The result is designed to be explainable: it shows a gender-presentation reference, a score, a confidence level, and the measured cues behind them. It does not determine gender identity, biological sex, or personal identity, and it does not treat one recording as a complete description of a person's voice.
The tool runs entirely in your browser. Your audio is never uploaded to a server. There is no signup required, and you can repeat the test whenever you want.
It can be useful when you are exploring voice training, practising spoken delivery, or comparing a repeated reading over time. The result is an acoustic snapshot, not medical, therapeutic, or identity advice. A voice coach or speech professional can provide personalised guidance when you need it.
For the most comparable sessions, use the same passage, room, microphone position, and speaking style each time. That consistency helps make changes in the median and pitch range easier to interpret than a single isolated number.
How Pitch Affects Voice Perception
Pitch is one of the most noticeable acoustic features of the human voice. Typical speaking pitch ranges vary widely: most adult voices fall somewhere between 85 Hz and 255 Hz, with significant overlap between groups.
Pitch is only one dimension of voice perception. Intonation patterns, spectral balance, resonance, speech rate, language, and listener expectations all shape what someone hears. This analyzer measures pitch movement and a browser-calculated spectral-balance proxy alongside pitch; it does not claim direct formant or clinical resonance measurement.
Pitch naturally varies from person to person and within the same person’s speech. Age, health, emotion, language, emphasis, and the sounds in a sentence can all change a speaking sample. That is why the tool shows both a median and an 80% range instead of treating one moment of speech as the whole voice.
Volume is different from pitch: volume is how loud a sound is, while pitch is how high or low it is. Speaking louder does not automatically raise pitch, but a very quiet or noisy recording can make the underlying pitch harder to measure. A calm, natural recording in a quiet room gives the clearest result.
For people engaged in voice training, tracking pitch over time can be a useful way to monitor practice. The future Pro version is planned to include private history and trend views for that use case.
Answers, without the jargon
Frequently Asked Questions
Is the voice test private?
Yes. All audio processing happens directly in your browser. Voice recordings are processed locally and are not sent to our servers. Waitlist submissions and basic analytics are handled separately and never include your audio.
What does the result mean?
The result is an explainable local reference for acoustic patterns in this recording. It combines pitch, pitch movement, and a spectral-balance proxy, then shows how each measured cue shaped the score. It does not identify your gender identity, biological sex, or personal identity.
How accurate is the pitch detection?
We use the YIN algorithm for fundamental-frequency estimation, together with local recording-quality checks. Confidence reflects the amount of clear voiced speech, signal separation, and pitch stability. The presentation reference is transparent and exploratory, not a clinical or identity classifier.
Can I use this on my phone?
Yes. The tool works on Chrome and Safari on both iOS and Android. Allow microphone access when prompted, and make sure the device is not in silent mode.
Why should I read a fixed text?
Reading a fixed text helps produce consistent results, especially when comparing recordings over time. Free speech is also available to test a natural speaking voice.
How can I improve my voice pitch control?
Voice pitch can be improved through regular practice and voice-training exercises. A speech therapist or voice coach is the most effective support. The upcoming Pro version will include progress tracking to help monitor changes over time.
Does background noise affect accuracy?
Yes. Background noise, room echo, and a microphone held too far away can make voiced frames harder to identify. For a clearer result, record in a quiet room, speak naturally, and keep the microphone about a hand’s length away.
What is the difference between pitch and volume?
Pitch describes how high or low a sound is and is measured in Hertz. Volume describes loudness. Speaking louder does not necessarily make your pitch higher, although a very quiet recording can make pitch harder to measure.
