Usable technology for the differently abled-hearing impairment

Abstract

Abstract:Hearing loss poses a serious challenge to access information that are in the form of audio or video on the internet. Text subtitles or closed captioning is a popular mechanism to make the audio embedded in the videos accessible to the hearing impaired. Alternatively, a sign language interpreter may translate the audio into sign language gestures. However, these aids are either expensive or technologically infeasible. In this paper, we propose a technique to enable a person with hearing impairment see the audio. The novel assistive tool is envisioned as a visual aid for the hearing impaired to comprehend the audio contained in a video. The tool produces a speech synchronised visual lip movement sequence for a video. The lip movement sequence is then superimposed onto and displayed along with the original video. A number of experiments have been conducted to determine the feasibility and usefulness of the proposed visual aid.

A Review on Enhancing Accessibility Through Image and Video Processing: Solutions for Differently Abled Individuals

“…This design facilitates ease of updates and maintenance, allowing each module to be refined without disrupting the system's overall functionality. Performance evaluation, the cornerstone of this phase, is conducted through a series of methodical tests designed to gauge the system's accuracy, responsiveness, and adaptability [32]. The accuracy of object recognition and scene analysis algorithms is quantified using standard metrics such as precision, recall, and F1 score.…”
