Gómez Ingeniería Cepstral features Hidden Markov Models Dynamic Time Warping IsolatedWord Recognition Isolated word recognition is usually performed by two diferent approaches, viz., Conventional Templatebasedand Hidden Markov Models (HMM)-based. A comparison between these approaches for isolated digitrecognition (in Spanish language) is performed in this paper. For the template-based approach, severalDynamic Time Warping algorithms are proposed and implemented in a Matlab environment, while for theHMM-based approach, the algorithms available in a freeware toolbox has been employed. The algorithmsare tested on a database collected during a Course on Digital Processing of Speech Signals at the Universityof Rosario. The test results show that a better performance can be obtained with a HMM-based digitrecognizer. 2005 artículo científico 1137-3601 https://www.redalyc.org/articulo.oa?id=92526910 en http://www.redalyc.org/revista.oa?id=925 Inteligencia Artificial.
