Feature extraction Speech recognition Natural language processing Multilayer perceptrons Digital electronics Signal theory (Telecommunication) Automatic speech recognition Speech perception Link to publisher's homepage at http://ieeexplore.ieee.org Automatic speech recognition (ASR) has made great strides with the development of digital signal processing hardware and software especially using English as the language of choice. In this paper, a new feature extraction method is presented to identify vowels recorded from 80 Malaysian speakers. The features were obtained from Vocal Tract Model based on Bandwidth (BW) approach. Bandwidth approach identifies frequency bands based on the first peak of vowel frequency responses. Mean and maximum energies were calculated from these Bandwidth frequency bands. Classification results from Bandwidth Approach were compared with the first 3-formant features using Linear Predictive method. A Multi-Layer Perceptron (MLP) and Multinomial Logistic Regression (MLR) were used to classify the vowels. MLR and MLP shows comparable classification results for BW approach of 96.40% and 96.59% respectively. Bandwidth approach obtained 5.49% higher classification rate than 3-formant features using MLP. 2009-08-13T03:00:40Z 2009-08-13T03:00:40Z 2009-07 Article p.75-79 978-1-4244-1723-0 http://ieeexplore.ieee.org/xpls/abs_all.jsp?=&arnumber=4590133 http://hdl.handle.net/123456789/6869 en Proceedings of the International Conference on Audio, Language and Image Processing (ICALIP 08) Institute of Eelectrical and Electronics Engineering (IEEE)
