Phonagnosia

Phonagnosia, sometimes called voice blindness, is an acquired auditory disorder, caused by brain damage, in which a person has difficulty recognizing familiar voices and telling voices apart even though their understanding of speech itself remains unaffected. First formally described in 1982 by Van Lancker and Cantor, it is considered the auditory counterpart of prosopagnosia, or face blindness, and belongs to a broader family of auditory agnosias that also includes cortical deafness and auditory verbal agnosia. Damage to the right hemisphere's inferior parietal region tends to impair voice recognition specifically, while damage to the temporal lobe impairs the ability to discriminate between voices, and some patients show one deficit without the other; a rarer developmental form exists in which the difficulty is present without any identifiable brain injury, and no treatment currently exists for the condition.
