Deafness leads due to missing auditoric phonatoric control mechanisms to changes of voice and language.

At 30 CI-patients the change of voice qualities hoarseness, roughness and breathiness before and after CI-operation was examined with the help of the acoustic voice analysis.

Therefore voice recordings took place before the operation as well as 1 week, 1, 3, 6 and 12 months after. The group of patients was confronted to a group of normal hearing persons (n=225). 3 comparisons were accomplished. 1. normal hearing persons with deaf before CI-operation, 2. normal hearing persons with the CI-group 12 months after CI-operation, 3. Comparison within the CI-group before and 12 months after CI-operation.

The evaluation of voice qualities took place with the computer program “Dr. Speech”, according to the RBH scale into 4 severity levels.

The comparison of voice qualities between deaf and normal hearing persons reached both with the parameter hoarseness and roughness statistically significant differences. During the rehablitation process of 1 year no significant changes were found.

In the result it showed up that the voice of deaf was more hoarse and rougher. Despite individual changes of voice qualities 1 year after CI-implantation no clear dependence on the auditory feedback could be proven for the total's group of the CI-patients.
