Voice production is the process by which sound is created in the larynx, or voice box, as air passes through the vocal cords and causes them to vibrate. This vibration produces sound waves that are then shaped and modified by the various parts of the vocal tract, including the throat, mouth, and nose, to create speech or singing. Research in voice production seeks to understand the mechanisms and dynamics of this process, as well as how it can be affected by factors such as age, gender, vocal health, and vocal training. Studies in this area often use techniques such as acoustic analysis, laryngoscopy, and electroglottography to investigate the physiology and acoustics of the voice. Voice production research has implications for fields such as speech therapy, singing pedagogy, and voice recognition technology.
