ABSTRACT
We reviewed the impact of singing on voice and speech production in normal and pathological aging, focusing on two acquired age-related disorders: non-fluent post-stroke aphasia and dysarthria. The result of the review of the extant literature suggests that singing has a protective effect on several aspects of human communication, particularly on voice, though aspects of human communication most reliably sensitive to singing remain to be identified. Singing might have a beneficial effect on communication-related outcomes in non-fluent aphasia and dysarthria but it appears more effective in the treatment of aphasia.
