Planning Effective Learning for the Visually Impaired in Federal University in Osun State, Nigeria: Technology Perspective

Abstract

The School system at the university level in developing nations provides the most impactful environment for effective learning and building human capital required for a future-knowledge economy. Unfortunately, less attention is given to the provision of appropriate platforms for the disabled to effectively learn in the university system. Notably, disabled individuals rely on their ability to listen to only speech to gain information quickly to aid learning. In this paper, a learning framework was implemented and tested from educational and technological perspectives. The study focused on an ideal combination of a human-like behavior with a computer application to build a one-way interactive medium between the computer and the user. Using qualitative and quantitative research, we focused on acoustic signal processing without the incorporation of visual input. The respondents used for the study include students, lecturers, specialists in specialized education, and technological experts. The result is a prototype system that translates texts into speech, and a synthesized speech representation of the text entered into the system to aid effective learning. The test results with different users revealed that a majority of 84.70%, 85.30%, 84%, and 86.70% of the users rated the system to have high-quality content, clarity, attractiveness, and responsiveness, respectively.
