Which aspect of speech is NOT considered a part of its production?

Cerebration is not considered a part of speech production. Instead, it refers to the process of thinking or the mental activity associated with using language. In contrast, phonation, resonance, and gestural expression are directly related to how speech sounds are produced. Phonation involves the production of sound by the vibration of the vocal cords. Resonance pertains to how sound is shaped by the vocal tract and oral cavity, affecting the quality of the voice. While gestural expression can accompany speech and influence communication, it is typically not classified as a fundamental aspect of speech production itself. Thus, focusing on the physiological and acoustic aspects of how speech is produced, cerebration stands apart as a cognitive process rather than a production mechanism.
