A QUIZZING SYSTEM FOR BLIND AND VISUALLY IMPAIRED CANDIDATES

Abstract

Abstract A major obstacle confronting blind and visually impaired students in their education is the lack of ability to function independently when it comes to certain things like taking exams. This paper is about a voice-enabled quizzing system which will be used to assess the students of a university especially the blind or visually impaired. The system was built on top of the voice over IP (VoIP) technologies in conjunction with an Automatic Speech Recognition (ASR) engine used to transform a speech to its actual text format. Multiple Choice and True/False Question are the only types of question allowed for a quiz; and the interactions with the system are fully operated by voice commands by using a mobile phone, a SIP-enabled device or a SIP-based application to call a number associated to an Interactive Voice Response (IVR) provided with a Voice User Interface (VUI) to manage quizzes as a lecturer and to take quizzes as a student. After the completion of a quiz, the result is provided automatically to the student by audio and email. Immediately after the end date and time set for a quiz is elapsed, an email containing statistical data and the attendants’ results is sent to the lecturer to analyze the performance of the students. However, the lecturer can review the quizzes results anytime by using the Voice User Interface. INTRODUCTION
