Pharyngeal pressure P and oral air flow U were measured in Moroccan Arabic (MA) guttural continuant consonants in the context aCa, and values were compared with those of [s z] and [l r]. The voiced laryngeal [ɦ] and the voiced epiglottal [ʢ] have the highest and lowest values of U respectively, which was expected since the former is breathy and the latter laryngealized. U is substantially higher in the voiceless epiglottal [ʜ] and uvular [χ] than in [s]. This result suggests that the primary articulation of MA epiglottal consonants is most likely at the level of the glottis and/or aryepiglottic sphincter, and that the supraglottal area is larger in the voiceless uvular than in [s]. P is much higher in uvular consonants than in [l r]. This disagrees with Halle's analysis according to which uvular consonants are sonorants and must be produced without a rise of P.
