Abstract: Data reported in an earlier study of prosody production in right-hemisphere-damaged (RHD) individuals (Pell, 1997a,b) were analyzed further to explore potential acoustic differences between normal speakers and those perceived to be emotionally ''flat.'' Results indicated that RHD patients were significantly less reliable at transmitting emotional meanings through prosody to a groups of normal listeners than age-matched normal speakers. Furthermore, when subjects obtaining low emotional ratings were considered separately, perceptually ''flat'' speakers (comprising half of the RHD group and one normal subject) were shown to employ substantially fewer acoustic cues to emotional contrasts than normal speakers, a pattern consistent with the impressionistic data.
