## What is Decibella Health?

Decibella helps you understand your menstruation cycle through a new signal: your voice.

Hormones impact your entire body, and the vocal tract is no exception. As a hormone-sensitive organ, your vocal tract can undergo subtle shifts throughout your menstrual cycle. Utilizing cutting-edge voice biomarker technology, Decibella provides a glimpse into what’s happening internally by revealing the physiological acoustic patterns of your voice.

By recording short daily voice samples and tracking your period, you can explore how your vocal energy, clarity, resonance, and stability fluctuate alongside your cycle phase, mood, and sleep.

Use Decibella to:
• Track your cycle with daily speech check-ins
• See acoustic trends across your follicular and luteal phases
• Log symptoms, mood, and body changes
• Build a personal baseline for what “normal” sounds and feels like for you

Our overarching goal is to improve women's health. By using Decibella, you can choose to help crowd-source de-identified voice data, directly enabling research into potential future accessible screening tools for hormonal conditions like PMDD, endometriosis, PCOS, perimenopause, etc.

(Decibella is not a medical device and does not diagnose, treat, cure, or prevent any condition. Always consult a qualified healthcare professional before making medical decisions.)
