SPEECH PRODUCTION

SPEECH PRODUCTION

1. Speech mechanism is technically termed Pulmonic Airstream Mechanism due to the leading role of the lungs in providing the necessary air for speech production. In humans, it is mainly egressive mechanism in that the air is expelled out through the vocal tract, being opposed to ingressive, in which the sounds are articulated by introducing air into the vocal tract

2. Speaking depends on the physical activity of breathing, but when comparing breathing and speaking we notice that in the first one the inhalation and exhalation phases are quite similar, whereas the exhalation phase is much longer in speaking
