In this paper we propose a phonetic study of emphatic consonants in standard Arabic, which is essentially based on the spectrographic examination of these consonants in various production contexts. This study allowed us to determine the pertinent parameters to the recognition of emphatic consonants in continu-ous speech. The recognition stage uses the SAPHA system, developed for the acoustic-phonetic decoding of standard Arabic and deals with the following points : • segmentation of the speech signal into large phonetic classes ; • extraction of parameters necessary for the recognition of emphatic consonants ; • phonetic identification of these consonants by using an expert system based on production rules. The results of the segmentation and of the recognition for three male speakers are given commented.
