Ayat Hafzalla Ahmed, Hager Morsy, Sherif Mahdi Abdo . Investigating Speech Attribute Features for Anti-Phone based Pronunciation Verification Approach. International Journal of Computer Applications. 183, 19 ( Aug 2021), 1-10. DOI=10.5120/ijca2021921465
With increased computing power, there has been a renewed interest in computer-assisted pronunciation learning (CAPL) applications in recent years; Automatic accurate pronunciation verification method plays an important role in automating the learning process and increasing its quality. Pronunciation errors can be divided into phonemic and prosodic error types. In this paper we propose a phoneme-level pronunciation verification method for Quranic Arabic based on anti-phone model. For each phoneme a binary support vector machine (SVM) classifier is trained to distinguish each phoneme from other phonemes. The (SVM) classifier is trained using speech attribute features derived from a bank of speech attribute detectors, namely manners and places of articulation. The feed forward deep neural network (DNN) architecture is utilized for the speech attribute detectors. The system is evaluated against speech corpora collected from fluent Quran reciters and achieved phoneme-level false-acceptance and false-rejection rates ranging from 2% to 25%.
