What does dysphonia mean?
Dysphonia is the clinical term for an impairment of the voice — a difficulty or abnormality in producing vocal sound. Rather than describing complete loss of voice (a condition called aphonia), dysphonia covers the wide spectrum of altered voice quality: hoarseness, breathiness, raspiness, weakness, strain, or tremor. Its causes range from benign and temporary, such as laryngitis or vocal overuse, to structural problems like nodules or polyps, and neurological conditions such as spasmodic dysphonia, which causes involuntary breaks in the voice. The word is used chiefly by physicians, particularly ear, nose and throat specialists, and by speech-language pathologists, so it carries a formal, technical register; a layperson would more naturally say they are 'hoarse.' Common clinical phrases include 'chronic dysphonia,' 'muscle tension dysphonia,' and 'spasmodic dysphonia.' Understanding the word is useful for navigating medical conversations about voice, since it names precisely what everyday language describes only vaguely.

- Any impairment or disorder of the voice, especially hoarseness or abnormal voice quality resulting from laryngeal dysfunction.

Etymology of dysphonia
Dysphonia derives from New Latin, combining the Greek prefix 'dys-' meaning 'bad' or 'difficult' with 'phōnē' meaning 'voice' or 'sound'. The same Greek root gives English a family of sound-related words, including 'symphony', 'telephone', and 'cacophony', as well as the contrasting medical term 'aphonia', meaning total loss of voice.
