Conventional speech recognition systems classify speech sounds according to their phonemes. Phoneme is the basic unit of speech, which if changed would change the whole meaning of the word. A number of research works have already been done in the conventional systems. Articulation refers to the manner of production of sound and the placement of tongue, lips and teeth. Not all the possible combinations of tongue and lip positions are used in speech. There may be incorrect placement of lips, teeth, tongue or even soft palate during speech. This often affects the clarity of speech. This paper is intended to classify the place of articulation of English words for the English language spoken by the Malaysians. In this approach the articulatory acoustic features are considered for the classification. Difficulty in pronunciation happens because of voice disorders. Articulation disorders constitute the most numerous of all speech disorders. About 3 out of 5 of all speech and language disorders are related to articulatory problems. This system is proposed to be used as an aid in the diagnosis of articulatory disorders.
