Third International Conference on Spoken Language Processing (ICSLP 94)
Prosody of recurrent utterances (RU) in four aphasic patients was investigated focusing on a prosodic factor of fundamental frequency (F0). In addition, we assessed numbers and lengths of phrases within an utterance to determine the general aspects of RUs. The results demonstrated that (1) all cases had some variability in the numbers and lengths of phrases, (2) of the four subjects, three had only a limited number of F0 contour types, but (3) the other (Case 4) showed remarkably rich variability in the types of F0 contours. A hypothesis is proposed that F0 control in speaking is independent of other mechanisms involved in producing RUs.
