Pitch floor

Your pitch floor is the lowest note your voice can comfortably produce. In voice feminization it matters because a voice tends to drop towards its floor when you are tired, ill, startled or not paying attention.

Where you'll meet it

In consultations and results, where raising the floor is often described as the real point of the operation, and in training, where therapists may measure your range from floor to ceiling.

How it is measured

Usually by having you glide down from a comfortable note to the lowest one you can make without the voice breaking into creak or fry, and recording it. Some clinics do it with a sustained vowel, some with a slide, and some take the bottom of your pitch across a reading passage instead. The methods give different numbers, which is one reason floors from two clinics are hard to compare. Your own before-and-after figures, taken the same way, are the useful ones.

Why the floor matters more than the average

A trained voice can sit well above its floor for hours, but only with some effort, and effort lapses: first thing in the morning, with a cold, after a drink, when you cough or laugh or shout. At those moments the voice drops back towards where it can rest, which is near the bottom of your range. People often describe this as their voice "falling out", and it is the single most common reason I have heard for considering surgery at all.

A glottoplasty shortens the vibrating length of the vocal folds, which lifts the whole range, floor included. The low notes are no longer available, so the voice has less far to fall, and a lapse lands somewhere higher than it used to. That is often worth more to people than any change in their average pitch.

What training can and cannot do

Training raises the pitch you choose to use. It does not remove the notes underneath, so the floor itself barely moves. What training does change is how often you fall to it, because a voice that is lighter and better supported costs less to hold. For some people that is enough, and the floor stops being a problem. For others, however well trained, the drop under stress stays, and that is the gap surgery is designed for.

Common misunderstandings

That a higher floor means a higher voice all the time. It sets the lowest the voice can go, not where it sits. Someone who speaks well above their new floor still needs the habits that put them there.

That the floor rises and stays exactly where it lands. It tends to settle over the first months as swelling goes down, which is why a result judged at a few weeks can look better or worse than the one you end up with.

The trade

Raising the floor usually lowers the ceiling a little too, and it can take some of the power out of the voice. Some surgeons measure the floor before and after and report it as a separate number from average speaking pitch. If yours does, ask for both, in semitones as well as hertz, and ask what a typical change looks like in their hands. If you sing, raise it at the first appointment, not the last.
