MyEarDroid is an Android application which identifies sounds in the home environment and alerts you that the events that produced them have occurred by vibration and visual notifications.
MyEarDroid has been designed as an aid for persons with hearing impairment, enabling them to receive announcements of events occurring in their home. T
MyEarDroid works by listening constantly through the smartphone’s microphone and comparing the sound with trained sound models to find matches. Using advanced methods, the app is capable of analysing descriptive features of audio in real time. To get better accuracy in identification you can record you own sounds: your doorbell, your alarm clock, etc.
