The glottal area at a mid-vowel position is calculated for 9 different voicing types (medium, loud and soft levels; mid, high and low pitch; normal, breathy and pressed phonation) for 10 different speakers, using an orifice equation. Considerable variability is found across speakers and voicing types, but some general consistencies are noted. Higher flowrates and larger glottal areas are associated with breathy voicing, whilst the opposite is true for pressed phonation. Compared to medium level, loud and soft voicing produce a corresponding increase and decrease respectively in subglottal pressure (Psg). Volume flowrate of air and subglottal pressure tend to increase when pitch is raised.
