The student Mariam Taha Sulaiman obtained her master's degree from the Department of Computer Sciences / University of Technology for her thesis (Suggested Arabic voice Captcha). The proposed Arabic Captcha includes Arabic pronunciation and presentation in an audio clip with a confusing background to the user. User is to rewrite what was read or heard. If the user is a real person and passes the test, the service will be processed by the website, otherwise access to the available service will not be granted and another voice test will be provided. This process continues until the correct answer is given by the user. In the proposed system, the test is generated as a random series of bits using a number of semi-random generators. The required number of bits is determined according to the number of symbols needed to distinguish. The group of Arabic symbols (letters and numbers) is converted to be concatenated with some distortions and effects to confuse attempts to penetrate the system
