R49: Voice disturbances

R49.0: Dysphonia

When they speak, every person’s spoken words have a very specific sound. This is the voice. The voice originates in the larynx and through the movements of mouth and throat.

The larynx can be seen particularly well in men as a bulging area at the front of the neck. This area is also called the Adam’s apple. The larynx is important for breathing and speaking. It consists mainly of cartilage, ligaments, and muscles. The vocal cords are also located in the larynx. The throat begins behind the mouth and nose. The throat connects the mouth and nose with the windpipe (trachea) and gullet (oesophagus).

There are many reasons why there can be a change in one's voice. An inflammation, or an injury to the larynx, for example, can result in a hoarse voice. Stress or talking loudly can also result in a hoarse voice. When we are hoarse, we may find it painful or an effort to talk. The voice may then also sound weak.
