Abstract	In some websites it is necessary to distinguishing between human users and computer programs which is known as CAPTCHA (Completely Automated Public Turing test to tell Computers and Human Apart). CAPTCHA methods are mainly based on the weak points of OCR systems and using them are undesirable to human users. In this paper a method has been presented for distinguishing between human users and computer programs on the basis of choice of an object shown on the screen. In this method some objects are chosen randomly and the pictures of these topics are downloaded from the Internet. Then after applying some effects such as rotation, all of the pictures are shown on the screen. Then we ask the user to choose a specific object. Instead of writing the question, it is said using a TTS (Text-To-Speech) system. Therefore children who maybe illiterate and cannot read, can easily pass the test. If the user chooses the right object, we can guess that the user is a human being and not a computer program. This method is specially developed for children websites. The main advantage of this method is its simplicity because the user does not have to read or type anything.
