Voice: vocal cords and disorders

  1. We use the voice every day. It soon becomes clear how the voice works exactly. Sometimes too much is asked of the vocal cords and problems can arise. Birth defects or certain diseases can also cause a different voice. Often there can be done something about it with voice rest, speech therapy or surgery:

What is the vote

  1. The voice is the sound produced by the vocal cords, which vibrate. The height of the voice depends on the structure of the larynx. It is smaller in women than in men. The length and tension on the vocal cords also plays a role in the height of the voice. The timbre, this is the quality of the sound, depends on the structure of the larynx, but also on the extension. The starter is the mouth and pharynx. This space is below and above the vocal cords. The voiced sounds are formed by connected and vibrating vocal cords. The voiceless sounds, on the other hand, are formed by open vocal cords. This by only moving the attachment and placing it in different positions.

Vocal cords

  1. The vocal cords are also called plicae. They consist of two pairs of mucosal folds located in the larynx. The top pair of vocal cords are the false vocal cords. The false vocal cords cannot be vibrated. The lower vocal cords are the true vocal cords, also called vocal folds. The true vocal cords contain muscle fibers. On the side of the vocal cleft is a connective tissue band, which is covered with mucous membrane. The vocal cords can widen, narrow and also completely close the vocal cleft. The muscles in the larynx control the width of the vocal cleft. They also partly regulate the tension in the vocal cords. Air flows through the narrow opening of the voice cleft. This air causes the vocal cords to vibrate.

Singing nodules or polyp on the vocal cord

  1. Due to the traffic use of the vocal cords or the frequent use of them, singing nodules can arise. These are also called polyps. A polyp is usually located on 1 of the 2 vocal cords. Often a polyp also occurs in mostly middle-aged men who are under stress. Polluted air or too dry and warm air can also cause a polyp. In the beginning there was a hoarse voice. Pitch breaks are also often found. While speaking, this sounds like a skipping of the voice. The polyps are removed with the help of an operation. Voice rest will be prescribed for two weeks, so speaking is not allowed. Often speech therapy is also given afterwards to learn to use the voice properly. A well-known artist with a voice polyp is the Dutch singer Frans Bauer.


  1. Hoarseness is understood to mean voicelessness and also changes in the voice. Hoarseness is a raw voice. Inflammation of the larynx can cause hoarseness. The vocal cords are red and swollen. When the inflammation becomes chronic, it can progress to polyps on the vocal cords. When there is vocal cord paralysis, it can also cause hoarseness. When complete voicelessness occurs, it is often the cause of a psychological cause. This can also cause throat cancer. Hoarseness should be treated with caution as it can develop into polyps. After six weeks, the hoarseness must be over, otherwise one must take it to a doctor. Shouting and screaming is not recommended. Smoking, alcohol and toxic substances are not good for the vocal cords. Talking during illness or fatigue is also discouraged. After all, one should not whisper too much.

Vocal cord paralysis

  1. When the vocal cords are completely paralyzed, this results in hoarseness. Sometimes the patient is very short of breath.

Speech disorders

  1. A speech disorder can be congenital, such as a cleft lip or open palate. nerve trunks can also be damaged. Furthermore, a cause can also be found in the brain: coordination disorders can ensure that the fine tuning of the muscle movements does not go well. Speech can be seriously affected by a brain haemorrhage.

Speech Impairment

  1. A speech impediment is the hissing or stuttering. Abnormalities of the speech organs can cause this. Developmental disorders are also one of the causes. When one cannot speak at all, it is called dumbness.
