Design and Implementation of Voice Time, Time Indicator Application for Diabetic Retinopathy Patients

Abstract

Diabetic retinopathy is a major cause of blindness in diabetic patients around the world. Patient with diabetic retinopathy strongly rely on the sense of hearing in communication and the sense of touch in recognizing objects. However, there are some objects that they cannot recognize, such as time. Therefore, it is undeniable that patient with diabetic retinopathy need help from others in carrying out some activities. One of the crucial activities that patients with diabetic retinopathy need to do is taking medication regularly according to the doctor's instructions. This research studies the design and implementation of Voice Time application which is developed to help diabetic retinopathy patient to know the time. Using speech recognition, diabetic retinopathy patient can give commands to mobile devices by means of voice. This application is equipped with emergency call and location-sending features which allow the patient to call the emergency contact while simultaneously sending text containing latitude and longitude information so that the emergency contact can locate the patient with Google map. From the results of the speech recognition performance test for voice time and emergency call features using dB meter application in 20 tests at varying distances (between 1 – 100 cm), sound intensity (amplitude) between 15 – 83 dB and 1 second 84 ms average delay to execute voice in emergency call feature were obtained.
