Verified step by step guidance

Understand that breathing rate is primarily controlled by the respiratory centers in the brain, which respond to the levels of carbon dioxide and oxygen in the blood.

Recognize that during voice production, the diaphragm plays a crucial role in controlling airflow and pressure, which are essential for sound production.

Identify that diaphragmatic contraction increases the volume of the thoracic cavity, reducing pressure and allowing air to flow into the lungs, which is essential for sustained voice production.

Consider that while vocal cord tension, laryngeal muscle relaxation, and tongue position affect the quality and pitch of the voice, they do not primarily influence the rate of breathing.

Conclude that diaphragmatic contraction is the primary factor influencing the rate of breathing during voice production, as it directly affects the airflow necessary for vocalization.
