We have developed the first smart wearable that continuously measures voice use and quality, with the goal of helping users manage their vocal health and potentially reduce the risk of fatigue or injury. This soft, flexible, small, and wireless sensor adheres comfortably to the upper chest, capturing vocal vibrations and instantly calculating real-time and cumulative voice use. Using advanced algorithms, it tracks and detects changes in voice quality and can deliver immediate feedback through haptic alerts and mobile notifications through a smartphone connection, empowering users to maintain healthy vocal habits.
Designed for anyone who relies on their voice professionally or personally, the technology opens opportunities for clinical care, providing objective data for more targeted voice habilitation and rehabilitation. Additional applications include improving surgical recovery for vocal injuries; helping individuals with hearing loss regulate vocal volume; assessing how radiation affects voice use in laryngeal cancer patients; monitoring changes in Parkinson’s voice profiles to track medication effects; supporting voice therapy goals to speak louder for Parkinson’s patients (LOUD and SPEAK OUT therapies) and encouraging increased vocalization in older adults to reduce age-related vocal decline.
