Diplophonia
Diplophonia
Diplophonia (/dɪploʊˈfoʊniə/; from Greek diploos meaning "double" and phone meaning "voice") is a medical condition characterized by the simultaneous production of two vocal sounds.
Definition
Diplophonia is a vocal disorder that occurs when the vocal cords produce two distinct pitches simultaneously. This condition is often associated with other voice disorders such as vocal fold paralysis, vocal fold paresis, and vocal fold nodules.
Symptoms
The primary symptom of diplophonia is the production of a dual-toned, or "double" voice. This can manifest as a voice that sounds shaky, hoarse, or as if two people are speaking at once. Other symptoms may include difficulty speaking, vocal fatigue, and a decreased range of vocal pitch.
Causes
Diplophonia can be caused by a variety of factors, including neurological conditions, vocal cord damage, and certain medications. It is often associated with conditions that affect the larynx, such as laryngitis, laryngeal cancer, and laryngeal papillomatosis.
Treatment
Treatment for diplophonia typically involves voice therapy, which may include exercises to improve vocal cord function and reduce strain. In some cases, surgery may be necessary to correct underlying physical abnormalities. Medications may also be used to treat any associated conditions.
