Laryngeal Adjustments in the Production of Voiceless<br />Obstruent Clusters in Berber

Laryngeal adjustments in voiceless obstruent clusters in Tashlhiyt Berber were examined bymeans of simultaneous transillumination, fibre-optic films and acoustic recordings. This languageallows a rich variety of voiceless clusters naturally. Several combinations of /s/ and /k/clusters including singleton and geminate consonants were examined. We focused on thenumber of glottal-opening gestures, the influence of manner of articulation and effects ofword boundaries. Results of this study provide evidence that the manner of articulation ofsegments and their position in the clusters have a major impact both on the number and onthe location of glottal abduction movements. Word boundaries did not influence laryngealadjustment to the same extent
