Hypophonia

Hypophonia

Hypophonia is a quiet voice, as in hypokinetic dysarthria. It is often a feature of parkinsonian syndromes (e.g., idiopathic Parkinson’s disease, multiple system atrophy), and may occur early in progressive supranuclear palsy. In isolation, other causes of dysphonia may need to be considered.
