The aim of the study was to investigate the performance of postlingually deaf adults on parts of the swedish dysarthria test Dysartribedömningen, and to compare these results with a matched group consisting of normal hearing speakers without any known speech disorder. The group consisted of 17 participants ranging between 42-86 years of age. Participants were assessed focusing on articulation, prosody, intelligibility and through a self-assessment of communicative participation. There was a statistically significant difference between groups on prosody that manifested primarily as a slower speaking rate in the cochlear implant users. No significant differences between groups as to articulation, intelligibility or communicative participation could be found. There was, however, a tendency towards less intelligible speech in the cochlear implant users, in both word and sentence tasks. There was no significant correlation between duration of deafness and intelligibility. These results underline a relatively small impact on the speech of the participating group.
