Track your period using your voice
Your vocal folds are hormone-sensitive tissue. We measure subtle voice biomarkers to help you better understand your hormonal health.
The science
How do hormones affect your speech?
Your vocal folds are hormone-sensitive tissue. As estrogen and progesterone shift across your cycle, so do the acoustic properties of your voice.
Resonance
Mucosal changes shift formants and spectral quality.
Tissue stiffness
Hormones alter tension and hydration of the vocal folds.
Glottal closure
Hormonal shifts affect how fully the folds close.
Tissue mass
Cyclical fluid retention changes how folds vibrate.
Which can be measured through subtle speech features:
