Sazali, Yaacob, Prof. Dr. κ-nearest neighbors (κ-NN) Linear Discriminant Analysis classifier (LDA) Linear Predictive Cepstral Coefficient (LPCC) Stuttering Link to publisher's homepage at http://ieeexplore.ieee.org/ Stuttering is a speech disorder in which the normal flow of speech is disrupted by occurrences of dysfluencies, such as repetitions, interjection and so on. There are high proportion of repetitions and prolongations in stuttered speech, usually at the beginning of sentences. Consequently, acoustic analysis can be used to classify the stuttered events. This paper describes particular stuttering events to be located as repetitions and prolongations in stuttered speech with feature extraction algorithm. Linear Predictive Cepstral Coefficient (LPCC) feature extraction is implemented to test its effectiveness in recognizing prolongations and repetitions in stuttered speech. In this work, two classifiers, Linear Discriminant Analysis classifier (LDA) and κ-nearest neighbors (κ-NN) are employed. Result shows that the LPCC and classifier (LDA and κ-NN) can be used for the recognition of repetitions and prolongations in stuttered speech with the best accuracy of 89.77%. 2010-08-18T06:56:16Z 2010-08-18T06:56:16Z 2009-12-14 Working Paper p.1-4 978-1-4244-5223-1 http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=5412080&tag=1 http://hdl.handle.net/123456789/8823 en Proceedings of the International Conference for Technical Postgraduates (TECHPOS) 2009 Institute of Electrical and Elctronics Engineering (IEEE) |
