Aphonia

Aphonia is the inability to produce voice. It is considered more severe than dysphonia. A primary cause of aphonia is bilateral disruption of the recurrent laryngeal nerve, which supplies nearly all the muscles in the larynx. Damage to the nerve may be the result of surgery (e.g., thyroidectomy) or a tumor.

Aphonia means "no sound." In other words, a person with this disorder has lost his/her voice.

Douglas Harper's Etymology Dictionary

aphonia

"want of voice, loss of voice, having no sound," 1719, from Modern Latin aphonia, from Greek aphonia "speechlessness," noun of quality from aphonos "voiceless," from a-, privative prefix (see a- (3)), + phone "voice" (see fame (n.)) + abstract noun ending -ia. Less-common anglicized form aphony is attested from 1827.

The reason for my doing so was that she had complained of complete aphonia on two occasions in the last two years, the first time when she was visiting her brother in Paris, and I was interested in establishing whether her temporary loss of speech might have had some connection with a lack of confidence in a foreign language.

Before proceeding, I asked her to recall the occasions on which she had suffered her aphonia and found that the first instance had followed swiftly on the incident in which the young doctor so suddenly interrupted her reverie in her bedroom.

We moved then to the question of how her aphonia, which I had wrongly thought at first to be connected to her anxiety about speaking a foreign language3 while temporarily removed from the company of the man she loved.
