Prosody. Production of prosody can be disrupted in three ways following brain damage: 111 (a) hyperprosody, which is rarely observed, is an exaggerated prosody; (b) dysprosody is a distorted prosody, which makes the patient sound as if he or she is speaking with a foreign accent; (c) aprosody is an attenuation or lack of normal prosody.

These disorders may arise if information about pitch is not used properly by the instructions generation subsystem, or if this information itself is disrupted. Similarly, it is possible that the movement execution subsystem is awry, so that it improperly modulates the output.

To our knowledge no network models have included a melodic contour to a sentence. It would be of interest to construct such models and then observe the kinds of errors they make when different amounts of the network are damaged. It is possible that the three varieties of problems in prosody reflect different amounts of damage to such a network.
