Sažetak
Foreign body in the oral cavity (dental prostheses) necessarily interfere with speech. Changes in anatomic and functional characteristics of the oral cavity may affect speech articulation. The purpose of this study was to show eventual differences in pronunciation of some sibilant nd s and palatal sounds. We tested three groups: subjects with removable partial dentures, the same group without removable partial dentures and a control group - students with complete dental arch with no prosthodontic treatment
or evidence of skeletal jaw discrepancy. Examination was performed on 30 subjects who had been wearing removable partial dentures in the upper and/or lower jaw and on 30 subjects in the control group. At the time of examination the prosthetic devices were 2 to 26 days old and with regard to aesthetics, retention, stability and function
satisfactory, according to professional standards. Subjects read six single words containing sibilant and palatal sounds in the initial word position, apart from sound c which was in the medial word position. The voice was recorded on minidisk (Sony MD, MZ-1) and analyzed
with Multispech Program - LPC. Analysis software. This acoustic analysis gave us peaks in the first 4 formants for each investigated sound, their bandwidths and intensity. It is reasonable to assume that subjects with removable partial dentures will probably have more problems with producing sound because of short adaptation period for
gaining complete speech adaptation. The same subjects without removable partial dentures will probably have much more accurate sounds production because of long term speech adaptation due to gradual tooth loss.
