The Effector Unit of Mysak's Model Represents the Expressive Transducer for the Auditory Modality (Speech).
The EFFECTOR UNIT of Mysak's Model is the Speech Mechanism. It consists of three parts:
The Motor, which is the muscle system that serves as the source of energy for speech (e.g., the Diaphragm and others); the
Generator, which is a mechanism for creating the sound for speech (e,g the Larynx); and the...
Modulator, which is a system of resonating air chambers that shape the air waves from the larynx to make them sound, among other things, human.
NOTES: See a nice little discussion on the expressive transducer (e.g., the speech mechansim).
