A team at Northwestern University has developed a wearable device that warns you when you're exceeding your vocal limits, saving your voice box from damage.
Vocal cord damage is a fairly common occurrence among music stars. From the likes of yesteryear icons such as Freddy Mercury and Julie Andrews to modern-day legends like Adele and Justin Timberlake, they all have had to battle vocal cord ailments — requiring surgeries to fix and weeks of not speaking to get their voice back to normal.
Related The sensor assembly uses these readings to measure the load on your vocal cords. However, it is also capable of logging other core metrics like sound volume, speaking duration, and time of the day. Your smartwatch is ready for it Once the threshold has been set, the wearable device will vibrate every time the wearer has exceed that limit. The flexible patch has its own battery and comes embedded with a bunch of motors to monitor voice activity at varied ranges. All the data is transmitted via Bluetooth to the mobile app, where users can also see a graphical breakdown of their vocal load.
Quick, easy, and incredibly accurate In order to train the underlying machine learning algorithms so that they don’t confuse singing with speaking, the team turned to opera students and classical singers. The team recorded their vocal activity patterns for a wide range of scenarios — such as singing, humming, reading, and more — to fine-tune the algorithms using 5,000 one-second clips from each participant.
