ABSTRACT
This research study is focused on design and implementation of a PDF to Audio System using ICT Centre, Akwa Ibom State Polytechnic as case Study. The objectives are to develop a system that will convert PDF text to audio for easy assimilation of document, to create a system that will easily detect a PDF file and convert to audio, to design a system that will assist people with reading disabilities to easily convert PDF text to audio files and to design and implement a system that will assist students’ reading comprehension skills. The significant of the study is specially designed to enable us implement a PDF to Audio System in ICT Centre, Akwa Ibom State Polytechnic, Ikot Osurua. The research methodology used is systematic methodology and the programming language used for the development of the system is Visual Basic.NET, and MS Access as database.
