A Communication Assistant Application for the Deaf

A deaf person is someone who has limitations or abnormalities in the organ of hearing that result in the inability to hear with varying degrees of hearing. The impact faced by the deaf people is the inhibition of verbal communication both expressively or speaking, unable to control the power of the voice when speaking, and receptively or understanding the conversation conveyed by the interlocutor. This creates barriers and difficulties for deaf people in communicating. In this paper, we propose an Internet of Things-based communication assistant application for the deaf, by utilizing a microcontroller, pulse sensor, and interfacing electret microphone amplifier. Our web-based application can provide information about the strength of the sound produced and the text of the conversation of the interlocutor. We demonstrated by experiment that our sensor devices and the wireless communication assistant application working properly.
