Researchers from Northwestern University have developed the first smart wearable device to continuously track how much people use their voices to prevent vocal fatigue and potential injury, as reported by MedicalXpress.

First-Of-Its-Kind

The wearable device is the first-of-its-kind that is battery-powered, wireless device that comes with its own set of algorithms. It is designed for professional singers, politicians, teachers, call center workers, coaches, and anyone who relies on their voices to make a living. 

The device may also help healthcare professionals remotely and continuously monitor patients with voice disorders. 

The wearable device was developed by a team of material scientists, biomedical engineers, opera singers, and a speech-language pathologist.

How it Works

The device is a soft, flexible device that is around the size of a postage stamp. It adheres to the upper chest to sense subtle vibrations associated with talking and singing. 

The captured data will be streamed via Bluetooth to the users' smartphone or tablet that will allow them to monitor their vocal activities in real time. It also measures cumulative total vocal usage. 

Through the device's custom machine-learning algorithms, it can distinguish between singing and speaking so singers can track each activity separately. 

The app will let users personalize vocal thresholds. When they near the threshold, their smartphone or other mobile device will deliver real-time haptic feedback as a notification. From there, users can rest their voices before pushing it too far. 

Vocal Overuse Today

Vocal overuse is a serious issue for many professionals, such as singers, actors, and public speakers. These individuals rely on their voices for their livelihood, and if their voices are damaged, it can lead to costly medical bills, as well as lost wages due to missed performances or speaking engagements.

It's no secret that the human voice is a powerful instrument, capable of conveying emotion, passion, and even command. But, as with any instrument, overuse can lead to serious damage to the vocal cords and even permanent vocal damage.

When it comes to vocal overuse, prevention is the best cure. It is important for professionals to practice proper vocal hygiene, such as drinking plenty of water, avoiding vocal strain, and taking regular breaks from speaking or singing. Additionally, vocal warm-ups and stretches can help to keep the vocal cords in top shape.

Ultimately, vocal overuse is a serious issue that can have serious consequences. By taking the necessary steps to prevent it, professionals who rely on their voices can help to ensure that their voices remain healthy and strong.

On the other hand, this new wearable device that has been developed may help further improve vocal health, especially those who use their voice to make money. The launch of the device on the market is still unknown, but so far, it is showing a lot of promise.
