Enhancing Hearing Accessibility Through IoT: A Review of Smart Hearing Device
Abstract: The challenges faced by individuals with hearing impairments extend beyond the actual loss of hearing and highlight a broader issue of communication barriers. Traditionally, it is assumed that individuals with hearing impairments would struggle with lip-reading and speaking, and therefore, they would benefit from using sign language and attending specialized schools to communicate with others. However, leveraging cutting-edge voice-to-text recognition technology could significantly narrow the gap between the hearing and …
