They have common usage in various web\nservices in order to be able to detect a human from computer programs\nautonomously. In this way, owners can protect their web services from bots. In\naddition to visual CAPTCHAs which consist of distorted images, mostly test\nimages, that a user must write some description about that image, there are a\nsignificant amount of audio CAPTCHAs as well. Briefly, audio CAPTCHAs are sound\nfiles which consist of human sound under heavy noise where the speaker\npronounces a bunch of digits consecutively. Generally, in those sound files,\nthere are some periodic and non-periodic noises to get difficult to recognize\nthem with a program but not for a human listener. We gathered numerous randomly\ncollected audio file to train and then test them using our SVM algorithm to be\nable to extract digits out of each conversation.","url_abs":"http://arxiv.org/abs/1901.02153v1","url_pdf":"http://arxiv.org/pdf/1901.02153v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"audio-captcha-recognition-using-rastaplp","repo_url":"https://github.com/cakmakaf/Audio-Captcha-Recognition","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null},{"paper_slug":"audio-captcha-recognition-using-rastaplp","repo_url":"https://github.com/balcilar/Audio-Captcha-Recognition","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[{"method_slug":"svm","method_name":"SVM"}],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
