Patients with Broca’s aphasia know what they want to say but can speak very little or not at all.
If they are able to speak, their words are produced very slowly, with great effort, and poorly articulated.
The interesting part is that even patients who cannot speak are often able to sing songs they knew before having Broca’s aphasia. Singing is normally controlled by the right hemisphere, and words to familiar songs are already stored there.
