Among the core components of CALL, pronunciation error detection and diagnostic feedback play a crucial role in analyzing learners\u2019 pronunciation issues and providing corrective suggestions, ultimately improving pronunciation proficiency and learning efficiency. While most existing studies focus solely on error detection, feedback correction remains underexplored. This paper addresses phoneme-level pronunciation errors caused by nonstandard articulatory movements, specifically focusing on six error types: Rising, Lowing, Fronting, Backing, Lengthing and Shorting. Using a machine learning approach, we develop a classification error detection model based on deep belief networks (DBN) and support vector machines (SVM), integrating the One-Class SVM (OC-SVM) approach to tackle issues of imbalanced sample data. The proposed DBN-SVM model is capable of detecting three additional error types \u2014 Fronting, Backing and Lengthing \u2014 completing the detection of all six error types. Experimental results validate the effectiveness of the model in pronunciation error detection and classification.<\/jats:p>","DOI":"10.1142\/s0218126625504262","type":"journal-article","created":{"date-parts":[[2025,7,25]],"date-time":"2025-07-25T06:58:16Z","timestamp":1753426696000},"source":"Crossref","is-referenced-by-count":0,"title":["Phoneme-Level Pronunciation Error Detection and Classification Using Deep Belief Networks and Support Vector Machines"],"prefix":"10.1142","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-1958-1658","authenticated-orcid":false,"given":"Shaonan","family":"Lin","sequence":"first","affiliation":[{"name":"Foreign Language Institute, Fujian Polytechnic Normal University, Fuqing, Fujian 350300, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1942-0374","authenticated-orcid":false,"given":"Yanshun","family":"Feng","sequence":"additional","affiliation":[{"name":"Hebei Yingyi Information Technology Co., Ltd., Hebei 050000, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2025,9,6]]},"reference":[{"key":"S0218126625504262BIB001","first-page":"78","volume-title":"L2 Writing Beyond English","author":"Rose H.","year":"2019"},{"key":"S0218126625504262BIB002","first-page":"65","volume":"14","author":"Uchida Y.","year":"2018","journal-title":"Tokyo Univ.
