SPPA 4030 Speech Science 2
Speech science investigates the fundamental questions pertaining to how speech is produced and how it is perceived (Kent, 1997).

SPPA 4030 Speech Science 5
Speech production may be described as the systematic regulation of air pressures and flows within the lungs and vocal tract
