Abstract
One of the most effectual and noteworthy methods in formation of the prosthetic fabrication is the detailed procedure which produce oral habituation. Approach to habituation in this study was performed with special reference to experimental palatal plate wearer's utterances. Five adult males served as the subjects. Experimental palatal plates were made and named F, A and P-plates. Speech materials were the eighty-two syllables which were selected from fourteen Japanese words. The analysing data sample of the utterances was measured in a time scale on a Sonagram. Statistical parameter, sample variances and correlation coefficients were calculated, and analyzed contents as follows: Almost compact variances were found in the preliminary experiment, but the fluctuation mode of sample variance was exhibited by features in three particular types after ten days.Correlation coefficient of intra-syllable phonemes was divided into two types, compact or diffuse to the preliminary data value. Optimal syllables of the experiment, based on variance and correlation coefficient, were thirteen syllables in ten words on F-plate, seven syllables in four words on A-plate and five syllables in three words on P-plate.“kou keiki keikai keikoku” and “ui ui sii hito” were selected for the possible materials of speech analysing in the habituation study.
