The teenager's speech began to stutter without warning. Then her conversational voice disappeared in every setting. Through all of it, she could still sing. Psychotherapy and speech therapy followed, and the clinicians who described her case reported a sobering result: "the symptoms persisted."
The case, published in Psychopharmacology Bulletin under the title "Singing Without Speaking," is unusual for the split between speaking and singing. The authors wrote that "no cases in the current literature examine the loss of conversational voice with preservation of singing voice."
