A brief outline of the research project

The articulation of post-velar consonants involves two types of constriction: Primary and secondary.  The former refers to pharyngeal, uvulas and laryngeals whereas the latter to emphatics.  Although in these sounds the primary and secondary articulations almost share similar spectral properties (i.e. high F1 and low F2), their articulatory attributes are different, which cause a lot of confusion.  My thesis will explore the role of epilarynx and tongue in the production of Arabic post-velar consonants.  The study will utilize dynamic UTI and MRI data.
