Evaluation de la compréhensibilité et conservation des fonctions prosodiques en perception de la parole de patients post traitement de cancers de la cavité buccale et du pharynx

Abstract : Comprehensibility evaluation and conservation of prosodic function in the speech of patients after Head and Neck carcinologic treatment In the framework of the Carcinologic Speech Severity Index, the present study proposes to perceptually evaluate speech of 45 speakers (37 patients, with treatment for Head and Neck cancer, 8 controls). 66 naïve listeners fulfilled 4 tasks, investigating on the one hand the conservation of 3 prosodic functions in these patients' speech (syntactic grouping, pragmatic focus, expression of modality) and their intelligibility/comprehensibility using a Sentence Verification Task on the other hand. Results indicate a global conservation of the tested prosodic functions in these patients' speech. The Sentence Verification paradigm results however help discriminate groups of speakers based on their perceived comprehensibility and show higher correlation with subjective evaluation of speech severity by medical practitioners. The results are discussed with regards to the communication adaptative role of prosody in the case of articulatory impairments.
