How to use it for voice training
- Record a baseline in your everyday voice before you change anything. It is the number you will measure progress against.
- Pick a target. The default is 180 Hz; choose “lower” as the direction if you are working on a deeper voice.
- Read the passage in your practice voice for about 30 seconds, then press Stop. You see your median, your usual range and the share of your speech that met the target.
- Repeat on different days. The history table keeps your sessions on this device so the trend is visible, not just today’s number.
Practise in short sessions. A target you can only hit while concentrating is a start; the goal is a voice you can keep up in a real conversation.
Choosing a pitch target
Adult women typically speak at about 165–255 Hz and adult men at about 85–180 Hz (Baken, 1987). Voice training resources commonly describe 155–185 Hz as a gender-ambiguous zone, which is why this tool shows it as its own band and why many people aim for a median at or a little above 180–185 Hz when feminizing.
A higher target is not automatically better. Pushing pitch far above what your voice does comfortably tends to sound strained and tire you quickly. Many trainers suggest raising pitch only as far as you can keep it relaxed and putting the rest of the effort into resonance.
Pitch is only part of a feminine or masculine voice
Research on how listeners judge a voice as male or female (Hillenbrand & Clark, 2009) finds that both pitch and the vocal tract’s resonances (formant frequencies) matter, and that pitch alone is not enough. That matches what voice trainers see: a raised pitch with unchanged, dark resonance is often still heard as male.
Other cues include resonance (a smaller, brighter-sounding vocal tract), intonation (more pitch movement across a sentence), vocal weight (a lighter, less buzzy quality) and articulation. This tool measures pitch; use your ears, recordings and ideally a coach for the rest.
Train safely
- Stop if your throat hurts or your voice goes hoarse, and rest the next day.
- Warm up, drink water and keep sessions short — several 10-minute sessions beat one long one.
- Do not whisper or speak in falsetto all day to “hold” a pitch; both tire the voice.
- Hoarseness that lasts more than a couple of weeks deserves a check by a doctor or speech-language pathologist. A speech-language pathologist with gender-affirming voice experience is the best guide for lasting change.

Frequently asked questions
What Hz is a feminine voice?
There is no single number. On this tool a median above 185 Hz falls in the female-typical band; resonance and intonation matter as much as pitch. See “Choosing a pitch target” above.
How long does voice feminization take?
It varies widely from person to person. Many people practise for months before a new voice feels automatic in conversation. Regular short sessions and tracking progress over weeks help more than occasional long ones.
Can pitch training damage my voice?
Straining can. Train at a pitch you can hold without tension, take breaks, and stop if it hurts or you get hoarse. Persistent hoarseness should be checked by a professional.
Can I use this for voice masculinization?
Yes. Set the direction to lower and choose a target; the tool then counts the share of your speech at or below it. Without testosterone, how far speaking pitch can be lowered comfortably is limited, so resonance work matters here too.
Where is my history stored?
