The analysis of pictures extracted from endoscopic video images
filmed during isolated Moroccan Arabic /i1C1i2C2/ items (where C1
= fricatives + C2 = plosives), showed that:
- All the segments of a whispered item are produced with an
anterior-posterior epilaryngeal compression, an adduction of
the ventricular bands and of the membranous part of the
glottis, and an opening at the level of its cartilaginous part.
- Glottal aperture differences observed in normal speech between
voiceless consonants tend, in the whispered speech, to
be maintained between the fricatives, and to be neutralised
between the plosives.
- We did not observe regular laryngeal articulatory differences
between all the whispered consonant pairs corresponding, in
normal speech, to the linguistic "voicing" contrast.
