What is the mechanism through which the human body produces speech?
The lungs are the major organ for breathing, and the expiratory cycle provides the power for the production of speech.
During the process of vocal fold abduction and adduction, which occurs at the level of the glottis, the sound of the voice is created at the level of the vocal folds. The sound or voice is then further molded as it passes through the resonating and articulating cavities, which include the nasal and oral cavities, among other places.
IMPORTANT ORGANS/ COMPONENTS OF RESONATION AND ARTICULATION
1. LUNGS
- primary organ for respiration
- With respiratory cycle, produces voice, but voice is produced at the level of your vocal folds during vocal fold adduction and abduction and is further shaped within the resonating cavities
2. VOICE BOX
- Vocal cords vibrate to form voice
3. VOCAL TRACT
- nasal/oral cavity
- Resonate voice
Listed below are the parts of the vocal tract.

Aside from respiration, it also acts as the primary or sole cavity for olfactory sensation.
