What does respiration in speech production refer to?

Respiration in speech production specifically refers to the physical act of breathing for sound production. This process involves the exchange of gases in the lungs, which provides the necessary airflow for creating vocal sounds. During speech, inhalation and exhalation are coordinated to maintain a consistent flow of air, which is essential for producing voice and enabling the dynamic features of speech, such as loudness and pitch.

When we speak, the diaphragm and other muscles must work effectively to control airflow, allowing for sustained utterance. This underlying respiratory function is crucial, as it provides the energy necessary for the vocal cords to vibrate, thereby producing sound. Without adequate respiration, speech would be limited in quality and effectiveness.
