In this study, we have observed the movements of the back of the tongue and the top of the larynx during the production of the « guttural » and « emphatic » Moroccan Arabic (henceforth MA) consonants. We found different shapes of the pharyngeal cavity in these consonants, and an anterior-posterior compression of the aryepiglottic sphincter occurring solely in the pharyngeal consonants. Acoustical analysis confirms that the VOT in emphatic stop is much shorter than in its non emphatic counterpart, and showed that only the F1 of /a/ (and not of /i/) is higher after a guttural than after plain (nonguttural) consonants.
