Which of the following is NOT a main component of speech production?

The choice indicating "Audition" is the correct answer as it does not constitute a main component of speech production. The process of speech production primarily involves three key components: respiration, phonation, and articulation.

Respiration refers to the airflow generated by the lungs, which provides the necessary energy for producing voice and sounds. Phonation occurs when the airflow from the lungs passes through the vocal folds, causing them to vibrate and produce sound. Articulation involves the manipulation of the sound created during phonation, impacting how speech sounds are shaped and pronounced by the articulators, including the tongue, lips, and palate.

On the other hand, audition pertains to the ability to hear and process auditory information. While it plays a critical role in how we perceive and produce speech, as it allows for feedback and adjustment of speech patterns, it is not directly involved in the actual mechanisms of producing speech. Thus, "Audition" is distinct from the production processes themselves.
