TRIO4

"Hear the difference with TRIO4" says the box. But how? TRIO4 is a device that allows users to listen to the subtle differences in their voice. The device is worn around the ear, and connects wirelessly to the user's phone. The device works by using the microphone of the phone and the device to listen to the user's voice. TRIO4 then analyses the voice, using artificial intelligence, to detect any changes in the frequency of the user's voice. TRIO4 then analyses the changes in frequency and provides feedback on how to improve. The device is made of a flexible silicone that fits comfortably around the ear.
