A Complete Mispronunciation Detection System for Arabic Phonemes using SVM

چکیده
Computer Assisted Language Learning Systems have gained a lot of attention in recent decades. Mispronunciation detection is probably the most important feature of these systems. It helps user to find out their pronunciation mistakes and provide useful feedback related to that mistake. Mispronunciation detection systems can be categorized in two classes; Posterior Probability based and Classifier based systems. In this paper pronunciation assessment problem is formulated as a classification problem. This research paper explores the Acoustic Phonetic Features (APF) rather than traditional Confidence Measure based scores for mispronunciation detection. Support Vector Machines (SVM) is used as a classifier to detect pronunciation mistakes. As a test case five Arabic phoneme are tested for mispronunciation detection. APF based classifier produced excellent results and give average accuracy of 97.5%. The proposed system outperforms the existing systems that have been developed for Arabic phonemes.

On Mispronunciation Lexicon Generation Using Joint-Sequence Multigrams in Computer-Aided Pronunciation Training (CAPT)
We investigate the use of joint-sequence multigrams to generate L2 mispronunciation lexicons for mispronunciation detection and diagnosis. In the joint-sequence framework, a pair of parallel strings (namely, the input string of either graphemes or phonemes of the canonical pronunciation and the phonetic string of the mispronunciation) are aligned to form joint units for probabilistic estimation...

Abstract- With the advancement and development of computer network technologies, the way for intruders has become smoother; therefore, to detect threats and attacks, the importance of intrusion detection systems (IDS) as one of the key elements of security is increasing. One of the challenges of intrusion detection systems is managing of the large amount of network traffic features. Removing un...
متن کاملOn the Efficacy of a Communicative Framework in Teaching English Phonological Features Absent in Persian to Iranian EFL Learners
Although Persian and English share many common phonemes, there are some phonological features that are present in English but absent in Persian which tend to lead to mispronunciation on the part of Persian learners of English, mostly through negative transfer. The present research assesses the efficacy of a communicative framework in improving Iranian adult EFL learners’ pronunciation of five E...

Hidden Markov Models (HMM) are currently widely used in Automatic Speech Recognition (ASR) as being the most effective models. Yet, they sometimes pose some problems of discrimination. The hybridization of Artificial Neural Networks (ANN) in particular Multi Layer Perceptrons (MLP) with HMM is a promising technique to overcome these limitations. In order to ameliorate results of recognition sys...
متن کاملContext Aware Mispronunciation Detection for Mandarin Pronunciation Training
Mispronunciation detection is an important component in a computer-assisted language learning (CALL) system. Many CALL systems only provide pronunciation correctness as the single feedback, which is not very informative for language learners. This paper proposes a context aware multilayer framework for Mandarin mispronunciation detection. The proposed framework incorporates the context informat...
