FAQs

How does the voice box (larynx) produce speech?

The voice box, or larynx, contains your vocal cords, which are small bands of muscle and tissue. When you speak, air from your lungs passes through the vocal cords, causing them to come together and vibrate. These vibrations create the sounds that make up speech.

How might a new throat patch help individuals speak without vocal cords?

A novel throat patch device, which is small and self-powered, can help people without vocal cords to speak. It has two main components: the first is a sensor that picks up muscle movements and turns them into electrical signals, and the second uses a machine-learning algorithm to interpret these signals into speech.

What are the four stages involved in producing the human voice?

The production of speech involves a stream of air that originates from the lungs and passes through the trachea and the oral and nasal cavities. There are four stages in this process: initiation (the start of the air stream), phonation (the vibration of vocal cords), oro-nasal process (the passage of sound through the mouth and nose), and articulation (the formation of distinct sounds).

How does an artificial voice box operate?

An artificial voice box, or voice prosthesis, typically works by using a handheld, battery-powered device that is placed against the skin beneath the jaw. This device creates vibrations that mimic the function of the vocal cords, enabling the user to produce speech sounds. Some devices work similarly to a "talk box" used in music, delivering the basic speech sounds through a tube that the user places in their mouth.
