measuring speech breathing: - Answer✔️✔️-Most speech measures come
from the oral cavity
some come from the nasal cavity
tube inside
transducer outside
measuring speech breathing: pressure patterns in speech - Answer✔️✔️-just
inside the mouth: Pio is intra-oral air pressure

measuring speech breathing: how do the ribcage and abdomen move as we
speak or sing? - Answer✔️✔️-increases and decreases in the volume of the
lungs
When you breathe in the diaphragm flattens out and pulls the base of the
lung downward this expands the volume inside the lungs and decreases
the pressure causing a person to breathe in; also pushes down on
abdominal viscera causing the belly to expand outwards
During typical breathing the ribcage and the abdomen both expand or
shrink together
subglottal pressure: what is it? - Answer✔️✔️-- abbreviated Ps or Psub
-pressure the lungs provide that goes up the trachea to larynx
- measure pressure directly below the larynx
- driving pressure for phonation, speech
- difficult to measure directly
How is P sub estimated? - Answer✔️✔️-Measure intraoral air pressure at a
particular time
when pressure in the mouth is the same as pressure below the larynx
-occurs during a brief time during the production of a P or vowels (PAA,
PAA, PAA)
• voiceless bilabial plosive
• vocal folds are abducted
- laryngeal devoicing gesture
• trachea and mouth are linked
- no pressure drop at the larynx
