RESUMO
This thesis analyzes the prosodic parameters that underlie the activity of hesitational repetitions in the production of nominal and prepositional phrases by aphasic and nonaphasic speakers. The most relevant aspects of the analysis are 1) the relationship between the movements of retraction and projection, as described in Auer (2009a), during the production of hesitational repetitions, 2) the relationship between the prosodic parameters, namely, fundamental frequency, duration and intensity, and finally, 3) the cooccurrence between the prosodic parameters and the movements of retraction and projection during the production of hesitational repetitions. Among the similarities between the two groups analyzed are a) vowel lengthening associated with the downward intonation curve in the characterization of the hesitational repetitions, 2) the occurrence of the same retraction movements in both aphasics and nonaphasics and 3) a greater similarity of prosodic features in the two groups in cases of multiple retraction. Among the most important differences are 1) the distribution of single and multiple retractions - aphasics produce a significantly greater number of multiple retractions - and 2) the extent of the features of hesitation throughout the structure M R1 Rx in aphasic speech. This study promotes a better understanding of the use of prosodic features by aphasic subjects in order to keep their participation in the interaction, besides assigning the relevance of certain linguistic parameters in specific production environments, as in the case of hesitational repetitions
