In this work, we exploited the acoustic parameter energy to a classification by a discriminant analysis to detect the primary accent syllables of type [CV] where [C] is a consonant and [V] a vowel, in Standard Arabic words. Generally, the three acoustic parameters used in prosody are: the fundamental, the duration and the energy, as well as the localization of the prominent syllable in final or initial position have an influence on the perception of the lexical accent in Arabic. A percentage of detection equal to 78% of the accentuated syllable shows the efficiency of such an approach that will be able to come to reinforce the methods based on the criteria of the fundamental, in the goal to improve the existing systems of synthesis and recognition in Standard Arabic.
